Generative artificial intelligence (AI) describes algorithms that help in creating/generating new content, including audio, code, images, text and videos.
In this kit, we build a Music generator from Text and Audio prompts using the Meta's MusicGen model. Meta's Audiocraft research team has released MusicGen, an open source deep learning language model that can generate new music based on text prompts and even be aligned to an existing song.
MusicGen is a single stage auto-regressive Transformer model capable of generating high-quality music samples conditioned on text descriptions or audio prompts. The text descriptions are passed through a frozen text encoder model to obtain a sequence of hidden-state representations. MusicGen is then trained to predict discrete audio tokens, or audio codes, conditioned on these hidden states. These audio tokens are then decoded using an audio compression model, such as EnCodec, to recover the audio waveform.
MusicGen has been trained on 20000 hours of licensed music. MusicGen is exceptional in its capacity to handle both text and musical cues, in addition to the effectiveness of the design and the speed of creation. The text establishes the fundamental style, which the audio file’s music subsequently follows.

QUESTION
Vuejs Webpack Compression Plugin not compressing
Asked 2022-Mar-28 at 12:53I need help debugging Webpack's Compression Plugin.
SUMMARY OF PROBLEM
- Goal is to enable asset compression and reduce my app's bundle size. Using the Brotli algorithm as the default, and gzip as a fallback for unsupported browsers.
- I expected a content-encoding field within an asset's Response Headers. Instead, they're loaded without the field. I used the Chrome dev tools' network tab to confirm this. For context, see the following snippet:
- No errors show in my browser or IDE when running locally.
WHAT I TRIED
- Using different implementations for the compression plugin. See below list of approaches:
- (With Webpack Chain API)
1config
2 .plugin('brotliCompress')
3 .use(CompressionWebpackPlugin, [{
4 exclude: /.map$/,
5 cache: true,
6 algorithm: 'brotliCompress',
7 test: /\.(js|css|html|svg)$/,
8 threshold: 10240,
9 minRatio: 0.8,
10 }])
11- (With Webpack Chain API)
1config
2 .plugin('brotliCompress')
3 .use(CompressionWebpackPlugin, [{
4 exclude: /.map$/,
5 cache: true,
6 algorithm: 'brotliCompress',
7 test: /\.(js|css|html|svg)$/,
8 threshold: 10240,
9 minRatio: 0.8,
10 }])
11config
12 .plugin('gzip')
13 .use(CompressionWebpackPlugin, [{
14 algorithm: 'gzip',
15 test: new RegExp('\\.(' + ['js', 'css'].join('|') + ')$'),
16 threshold: 8192, // Assets larger than 8192 bytes are not processed
17 minRatio: 0.8, // Assets compressing worse that this ratio are not processed
18 }])
19- (With Webpack Chain API)
1config
2 .plugin('brotliCompress')
3 .use(CompressionWebpackPlugin, [{
4 exclude: /.map$/,
5 cache: true,
6 algorithm: 'brotliCompress',
7 test: /\.(js|css|html|svg)$/,
8 threshold: 10240,
9 minRatio: 0.8,
10 }])
11config
12 .plugin('gzip')
13 .use(CompressionWebpackPlugin, [{
14 algorithm: 'gzip',
15 test: new RegExp('\\.(' + ['js', 'css'].join('|') + ')$'),
16 threshold: 8192, // Assets larger than 8192 bytes are not processed
17 minRatio: 0.8, // Assets compressing worse that this ratio are not processed
18 }])
19config
20 .plugin('CompressionPlugin')
21 .use(CompressionWebpackPlugin)
22- (Using vue-cli-plugin: compression) This fails due to a Missing generator error when I use
vue invoke compressionin response to an IDE console message after I runvue add compressionas an alternative to using Webpack Chain API for compression configuration.
1config
2 .plugin('brotliCompress')
3 .use(CompressionWebpackPlugin, [{
4 exclude: /.map$/,
5 cache: true,
6 algorithm: 'brotliCompress',
7 test: /\.(js|css|html|svg)$/,
8 threshold: 10240,
9 minRatio: 0.8,
10 }])
11config
12 .plugin('gzip')
13 .use(CompressionWebpackPlugin, [{
14 algorithm: 'gzip',
15 test: new RegExp('\\.(' + ['js', 'css'].join('|') + ')$'),
16 threshold: 8192, // Assets larger than 8192 bytes are not processed
17 minRatio: 0.8, // Assets compressing worse that this ratio are not processed
18 }])
19config
20 .plugin('CompressionPlugin')
21 .use(CompressionWebpackPlugin)
22 pluginOptions: {
23 compression: {
24 brotli: {
25 filename: '[file].br[query]',
26 algorithm: 'brotliCompress',
27 include: /\.(js|css|html|svg|json)(\?.*)?$/i,
28 minRatio: 0.8,
29 },
30 gzip: {
31 filename: '[file].gz[query]',
32 algorithm: 'gzip',
33 include: /\.(js|css|html|svg|json)(\?.*)?$/i,
34 minRatio: 0.8
35 }
36 }
37 },
38- Lastly, I tried setting the threshold field to 0 as well as raising it larger than 10k bytes.
POINTS OF SIGNIFICANCE
- The above attempts didn't achieve the goal I stated in the first summary bullet and were used in place of the previous approaches tested.
- I prioritized my efforts with Webpack Chain API since it resulted in no errors when rebuilding and running the app.

ANSWER
Answered 2021-Sep-30 at 14:59It's not clear which server is serving up these assets. If it's Express, looking at the screenshot with the header X-Powered-By, https://github.com/expressjs/compression/issues/71 shows that Brotli support hasn't been added to Express yet.
There might be a way to just specify the header for content-encoding manually though.
QUESTION
Different behavior between match and unwrap
Asked 2022-Mar-15 at 18:39I have done a small program, and it shows a weird behavior that I cannot explain. I am using rodio crate to try out some audio stuff.
I have done two programs that, in my opinion, should give the same result.
The first one I use matches to handle errors:
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11In the last one, I have used unwrap instead.
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11let (_, handle) = rodio::OutputStream::try_default().unwrap();
12let s = Sink::try_new(&handle).unwrap();
13println!("{}",s.len());
14The first one executes the print statement as expected, while the last one panics in the second unwrap.
It is very strange to me as soon as there is no error propagation, implicit conversions or other things that can explain that. The problem here is not related to the error itself but the difference between the two codes.
ANSWER
Answered 2021-Sep-30 at 19:08The issue is one of scoping and an implementation detail of rodio: the one critical item here is OutputStream::try_default(), it doesn't really matter how you handle Sink::try_new(&handle) it'll always behave the same, not so try_default, if you match or if let it it'll work fine, if you unwrap it it'll fail.
But why would that be, the two should be equivalent. The answer is in the details of rodio, specifically of OutputStreamHandle:
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11let (_, handle) = rodio::OutputStream::try_default().unwrap();
12let s = Sink::try_new(&handle).unwrap();
13println!("{}",s.len());
14pub struct OutputStreamHandle {
15 mixer: Weak<DynamicMixerController<f32>>,
16}
17So an OutputStreamHandle (OSH thereafter) only holds a weakref to a DynamicMixerController, to which the OutputStream (OS thereafter) holds a strong reference.
This means the OSH only "works" as long as the OS is alive.
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11let (_, handle) = rodio::OutputStream::try_default().unwrap();
12let s = Sink::try_new(&handle).unwrap();
13println!("{}",s.len());
14pub struct OutputStreamHandle {
15 mixer: Weak<DynamicMixerController<f32>>,
16}
17let (_, handle) = OutputStream::try_default().unwrap();
18does not name the OS, so doesn't hold onto it, it's immediately dropped, the Arc is released and the OSH holds onto nothing, and the sink is unhappy.
How can the other one work then? Because
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11let (_, handle) = rodio::OutputStream::try_default().unwrap();
12let s = Sink::try_new(&handle).unwrap();
13println!("{}",s.len());
14pub struct OutputStreamHandle {
15 mixer: Weak<DynamicMixerController<f32>>,
16}
17let (_, handle) = OutputStream::try_default().unwrap();
18 if let Ok((_, handle)) = OutputStream::try_default() {
19 let sink = Sink::try_new(&handle).unwrap();
20 println!("match {}", sink.len());
21 }
22is really rather
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11let (_, handle) = rodio::OutputStream::try_default().unwrap();
12let s = Sink::try_new(&handle).unwrap();
13println!("{}",s.len());
14pub struct OutputStreamHandle {
15 mixer: Weak<DynamicMixerController<f32>>,
16}
17let (_, handle) = OutputStream::try_default().unwrap();
18 if let Ok((_, handle)) = OutputStream::try_default() {
19 let sink = Sink::try_new(&handle).unwrap();
20 println!("match {}", sink.len());
21 }
22{
23 let _var = OutputStream::try_default();
24 if let Ok((_, handle)) = _var {
25 let sink = Sink::try_new(&handle).unwrap();
26 println!("match {}", sink.len());
27 }
28}
29so the match/if let itself is keeping the Result alive, which is a blessing here (but causes issues just the next question over).
Since the Result is kept alive, the tuple is kept alive, the OutputStream is kept alive, the Arc is kept alive, and thus the OSH has a working mixer, which the sink can make use of.
You can fix the issue of the second version by binding the OutputStream to a "proper" name e.g.
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11let (_, handle) = rodio::OutputStream::try_default().unwrap();
12let s = Sink::try_new(&handle).unwrap();
13println!("{}",s.len());
14pub struct OutputStreamHandle {
15 mixer: Weak<DynamicMixerController<f32>>,
16}
17let (_, handle) = OutputStream::try_default().unwrap();
18 if let Ok((_, handle)) = OutputStream::try_default() {
19 let sink = Sink::try_new(&handle).unwrap();
20 println!("match {}", sink.len());
21 }
22{
23 let _var = OutputStream::try_default();
24 if let Ok((_, handle)) = _var {
25 let sink = Sink::try_new(&handle).unwrap();
26 println!("match {}", sink.len());
27 }
28}
29let (_stream, handle) = OutputStream::try_default().unwrap();
30prefixing a name with _ will create the binding for real, but will suppress the "unused variable" warning.
FWIW being careful around this sort of things is incredibly important around RAII types whose values you "don't need", most commonly mutexes protecting code as opposed to data:
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11let (_, handle) = rodio::OutputStream::try_default().unwrap();
12let s = Sink::try_new(&handle).unwrap();
13println!("{}",s.len());
14pub struct OutputStreamHandle {
15 mixer: Weak<DynamicMixerController<f32>>,
16}
17let (_, handle) = OutputStream::try_default().unwrap();
18 if let Ok((_, handle)) = OutputStream::try_default() {
19 let sink = Sink::try_new(&handle).unwrap();
20 println!("match {}", sink.len());
21 }
22{
23 let _var = OutputStream::try_default();
24 if let Ok((_, handle)) = _var {
25 let sink = Sink::try_new(&handle).unwrap();
26 println!("match {}", sink.len());
27 }
28}
29let (_stream, handle) = OutputStream::try_default().unwrap();
30let _ = m.lock().unwrap();
31doesn't do anything, the mutex guard is not kept alive, so the lock is immediately released. In that case, you'd rather
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11let (_, handle) = rodio::OutputStream::try_default().unwrap();
12let s = Sink::try_new(&handle).unwrap();
13println!("{}",s.len());
14pub struct OutputStreamHandle {
15 mixer: Weak<DynamicMixerController<f32>>,
16}
17let (_, handle) = OutputStream::try_default().unwrap();
18 if let Ok((_, handle)) = OutputStream::try_default() {
19 let sink = Sink::try_new(&handle).unwrap();
20 println!("match {}", sink.len());
21 }
22{
23 let _var = OutputStream::try_default();
24 if let Ok((_, handle)) = _var {
25 let sink = Sink::try_new(&handle).unwrap();
26 println!("match {}", sink.len());
27 }
28}
29let (_stream, handle) = OutputStream::try_default().unwrap();
30let _ = m.lock().unwrap();
31let _lock = m.lock().unwrap():
32or even better
1let sink : Option<Sink> = match rodio::OutputStream::try_default() {
2 Ok((_, handle)) => {
3 match Sink::try_new(&handle) {
4 Ok(s) => Some(s),
5 Err(_e) => None,
6 }
7 },
8 Err(_e) => None,
9};
10println!("{}", sink.unwrap().len());
11let (_, handle) = rodio::OutputStream::try_default().unwrap();
12let s = Sink::try_new(&handle).unwrap();
13println!("{}",s.len());
14pub struct OutputStreamHandle {
15 mixer: Weak<DynamicMixerController<f32>>,
16}
17let (_, handle) = OutputStream::try_default().unwrap();
18 if let Ok((_, handle)) = OutputStream::try_default() {
19 let sink = Sink::try_new(&handle).unwrap();
20 println!("match {}", sink.len());
21 }
22{
23 let _var = OutputStream::try_default();
24 if let Ok((_, handle)) = _var {
25 let sink = Sink::try_new(&handle).unwrap();

29let (_stream, handle) = OutputStream::try_default().unwrap();
30let _ = m.lock().unwrap();
31let _lock = m.lock().unwrap():

145I understand that there is a thread already about similar issue but it still doesn't solve the issue. Hence seeking out help
I really have no idea why is the error occurring and how to resolve it. I am pasting the script below for your reference. Can some one please help? Thank you in advance

279There's the issue. Python 3.10.0 has a bug with PyInstaller 4.6. The problem isn't you or PyInstaller. Try converting it using Python 3.9.7 instead. Ironic, considering 3.10.0 was suppose to be a bugfix update.
QUESTION
Javascript: frame precise video stop
Asked 2022-Jan-28 at 14:55I would like to be able to robustly stop a video when the video arrives on some specified frames in order to do oral presentations based on videos made with Blender, Manim...
I'm aware of this question, but the problem is that the video does not stops exactly at the good frame. Sometimes it continues forward for one frame and when I force it to come back to the initial frame we see the video going backward, which is weird. Even worse, if the next frame is completely different (different background...) this will be very visible.
To illustrate my issues, I created a demo project here (just click "next" and see that when the video stops, sometimes it goes backward). The full code is here.
The important part of the code I'm using is:
1 var video = VideoFrame({
2 id: 'video',
3 frameRate: 24,
4 callback: function(curr_frame) {
5 // Stops the video when arriving on a frames to stop at.
6 if (stopFrames.includes(curr_frame)) {
7 console.log("Automatic stop: found stop frame.");
8 pauseMyVideo();
9 // Ensure we are on the proper frame.
10 video.seekTo({frame: curr_frame});
11 }
12 }
13 });
14So far, I avoid this issue by stopping one frame before the end and then using seekTo (not sure how sound this is), as demonstrated here. But as you can see, sometimes when going on the next frame it "freezes" a bit: I guess this is when the stop happens right before the seekTo.
PS: if you know a reliable way in JS to know the number of frames of a given video, I'm also interested.
Concerning the idea to cut the video before hand on the desktop, this could be used... but I had bad experience with that in the past, notably as changing videos sometimes produce some glitches. Also, it can be more complicated to use at it means that the video should be manually cut a lot of time, re-encoded...
EDIT Is there any solution for instance based on WebAssembly (more compatible with old browsers) or Webcodec (more efficient, but not yet wide-spread)? Webcodec seems to allow pretty amazing things, but I'm not sure how to use them for that. I would love to hear solution based on both of them since firefox does not handle webcodec yet. Note that it would be great if audio is not lost in the process. Bonus if I can also make controls appear on request.
EDIT: I'm not sure to understand what's happening here (source)... But it seems to do something close to my need (using webassembly I think) since it manages to play a video in a canvas, with frame... Here is another website that does something close to my need using Webcodec. But I'm not sure how to reliably synchronize sound and video with webcodec.
EDIT: answer to the first question
Concerning the video frame, indeed I chose poorly my frame rate, it was 25 not 24. But even by using a framerate of 25, I still don't get a frame-precise stop, on both Firefox and Chromium. For instance, here is a recording (using OBS) of your demo (I see the same with mine when I use 25 instead of 24):
one frame later, see that the butter "fly backward"(this is maybe not very visible with still screenshots, but see for instance the position of the lower left wing in the flowers):
I can see three potential reasons: first (I think it is the most likely reason), I heard that video.currentTime was not always reporting accurately the time, maybe it could explain why here it fails? It seems to be pretty accurate in order to change the current frame (I can go forward and backward by one frame quite reliably as far as I can see), but people reported here that video.currentTime is computed using the audio time and not the video time in Chromium, leading to some inconsistencies (I observe similar inconsistencies in Firefox), and here that it may either lead the time at which the frame is sent to the compositor or at which the frame is actually printed in the compositor (if it is the latest, it could explain the delay we have sometimes). This would also explain why requestAnimationVideoFrame is better, as it also provides the current media time.
The second reason that could explain that problem is that setInterval may not be precise enough... However requestAnimationFrame is not really better (requestAnimationVideoFrame is not available in Firefox) while it should fire 60 times per seconds which should be quick enough.
The third option I can see is that maybe the .pause function is quite long to fire... and that by the end of the call the video also plays another frame. On the other hand, your example using requestAnimationVideoFrame https://mvyom.csb.app/requestFrame.html seems to work pretty reliably, and it's using .pause! Unfortunately it only works in Chromium, but not in firefox. I see that you use metadata.mediaTime instead of currentTime, maybe this is more precise than current time.
The last option is that there is maybe something subtle concerning vsync as explained in this page. It also reports that expectedDisplayTime may help to solve this issue when using requestAnimationVideoFrame.
ANSWER
Answered 2022-Jan-21 at 19:18The video has frame rate of 25fps, and not 24fps:
After putting the correct value it works ok: demo
The VideoFrame api heavily relies on FPS provided by you. You can find FPS of your videos offline and send as metadata along with stop frames from server.
The site videoplayer.handmadeproductions.de uses window.requestAnimationFrame() to get the callback.
There is a new better alternative to requestAnimationFrame. The requestVideoFrameCallback(), allows us to do per-video-frame operations on video.
The same functionality, you domed in OP, can be achieved like this:
1 var video = VideoFrame({
2 id: 'video',
3 frameRate: 24,
4 callback: function(curr_frame) {
5 // Stops the video when arriving on a frames to stop at.
6 if (stopFrames.includes(curr_frame)) {
7 console.log("Automatic stop: found stop frame.");
8 pauseMyVideo();
9 // Ensure we are on the proper frame.
10 video.seekTo({frame: curr_frame});
11 }
12 }
13 });
14 const callback = (now, metadata) => {
15 if (startTime == 0) {
16 startTime = now;
17 }
18 elapsed = metadata.mediaTime;
19 currentFrame = metadata.presentedFrames - doneCount;
20
21 fps = (currentFrame / elapsed).toFixed(3);
22 fps = !isFinite(fps) ? 0 : fps;
23
24 updateStats();
25 if (stopFrames.includes(currentFrame)) {
26 pauseMyVideo();
27 } else {
28 video.requestVideoFrameCallback(callback);
29 }
30 };
31 video.requestVideoFrameCallback(callback);
32And here is how demo looks like.
The API works on chromium based browsers like Chrome, Edge, Brave etc.
There is a JS library, which finds frame rate from video binary file, named mediainfo.js.
QUESTION
How to detect if a device can play Dolby Atmos Sound with Javascript
Asked 2021-Dec-24 at 06:57I am looking for a way to detect if the device I am using can support Dolby Atmos sounds.
After searching around I found this call.
https://github.com/w3c/media-capabilities/blob/main/explainer.md#spatial-audio
1navigator.mediaCapabilities.decodingInfo({
2 type: 'file';
3 audio: {
4 // Determine support for Dolby Atmos by checking Dolby Digital Plus and spatial rendering.
5 contentType: "audio/mp4; codecs=ec-3",
6 spatialRendering: true,
7 }
8}).then(result => {
9 // Do things based on results.
10 console.log(result.supported);
11 console.log(result.smooth);
12 console.log(result.powerEfficient);
13});
14I guess this detects the codec the media was encoded with and if it support spatial audio.
Detecting the codec doesn't necessarily detect whether the system can support Dolby Atmos from what I understand the system needs to be connect to a receiver via a HDMI cable with arch support.
https://www.samsung.com/my/support/tv-audio-video/how-to-use-hdmi-arc-on-samsung-smart-tv/
The receiver needs to support multiple outputs to take the meta data sent from the codec parse through the HDMI arch and then the receiver knows which speaks to send the specific sounds too.
Something like this. https://www.richersounds.com/catalog/product/view/id/16007/s/denon-avcx8500h-black/
What reliable way is there to detect if your system will truly support Dolby Atmos whether its with a receiver or a Dolby Atmos compliant sound bar.
Any suggestions?

Correct.
What reliable way is there to detect if your system will truly support Dolby Atmos whether its with a receiver or a Dolby Atmos compliant sound bar.
Unfortunately, this undetectable from the browser.
The browser itself and even the OS doesn't always know what is downstream. Sorry for the bad news!

FFMPEG's xstack command results in out of sync sound, is it possible to mix the audio in a single encoding?
Asked 2021-Dec-16 at 21:11I wrote a python script that generates a xstack complex filter command. The video inputs is a mixture of several formats described here:
I have 2 commands generated, one for the xstack filter, and one for the audio mixing.

46[swscaler @ 0000020bac5a19c0] Warning: data is not aligned! This can lead to a speed loss
47I think this is unrelated to audio desyncing this unaligned data is about x264 resolutions being multiple of 16, but my filter takes this into account already.
There is a perceptible audio desyncing, which is the main problem I am having. FFMPEG doesn't seem to get other errors. Is it because I use 2 commands to mix the audio after? How could I proceed to to the xstack stage and the audio mixing in a single stage?
I'm a bit confused as how FFMPEG handles diverse framerates. I was told to reencode all the video inputs before performing the xstack stage, but I would create some disk overhead, so I'd rather do it in a single ffmpeg job it possible.
ANSWER
Answered 2021-Dec-16 at 21:11I'm a bit confused as how FFMPEG handles diverse framerates
It doesn't, which would cause a misalignment in your case. The vast majority of filters (any which deal with multiple sources and make use of frames, essentially), including the Concatenate filter require that be the sources have the same framerate.
For the concat filter to work, the inputs have to be of the same frame dimensions (e.g., 1920⨉1080 pixels) and should have the same framerate.
(emphasis added)
The documentation also adds:
Therefore, you may at least have to add a scale or scale2ref filter before concatenating videos. A handful of other attributes have to match as well, like the stream aspect ratio. Refer to the documentation of the filter for more info.
You should convert your sources to the same framerate first.

Audio recording in Python with Pyaudio, error ||PaMacCore (AUHAL)|| ... msg=Audio Unit: cannot do in current context

Answered 2021-Nov-03 at 16:29Apparently the problem were mismatched bitrates in BlackHole's aggregated output device. I was aggregating Blackhole's output (44,1kHz) and the Mac Speakers (48kHz). This did not cause any consistent bad behaviour but sometimes led to these errors.
QUESTION
Java mp4parser to create a single .m4s fragment— invalid moov box
Asked 2021-Oct-22 at 06:01This use case is a service that manually encodes a series of uncompressed .wav media segments into .m4s fragments for broadcast via MPEG-DASH, using ffmpeg to compress the .wav to .aac and sannies/mp4parser to assemble the aac audio into an .m4s media fragment.
I created this public GitHub project to reproduce the issue in its entirety.
For example, here's the custom CustomFragmentMp4Builder.java class.
It's critical that we be able to designate this single .m4s fragment with a sequence number (index) that we will manually increment for each media segment.
The objective is to build an .m4s fragment comprising the box types SegmentTypeBox, SegmentIndexBox, and MovieFragmentBox. As For reference, I have used mp4parser to inspect an .m4s fragment that was generated via ffmpeg -f hls. This specification is available here as a .yaml file
My implementation creates an MP4 without error. But, when the unit test attempts to read the file that the ChunkMp4Builder just wrote to a temp folder:
1java.lang.RuntimeException: A cast to int has gone wrong. Please contact the mp4parser discussion group (3724673092)

However, at the end of the file appears a box of an unknown type:
ANSWER
Answered 2021-Oct-21 at 20:57Your m4s segments are invalid due to an incorrect mdat atom size.
For example in test5-128k-151304042.m4s the mdat is marked as having a length of 16 bytes but there is data at the end and file size is 164884.
The parser then attempts to read an invalid offset. avc5 is not an atom but actually part of the string "Lavc58.54.100". The length read as 3724673100 is also invalid and greater than the max for a 32-bit integer, hence the invalid cast to int.
In your implementation you have:
1java.lang.RuntimeException: A cast to int has gone wrong. Please contact the mp4parser discussion group (3724673092)

11isoFile.addBox(moov);
12List<SampleSizeBox> stszs = Path.getPaths(moov, "trak/mdia/minf/stbl/stsz");
13// ...
14
15protected MovieFragmentBox createMovieFragmentBox(Movie movie) {
16 MovieFragmentBox mfb = new MovieFragmentBox();
17 // ...
18}
19This is not a moov atom, it's a moof. There is no stsz in there and the sum of your sample sizes is 0 so the total calculated size of the mdat is 16 + 0.
The moov is supposed to be in the initialization segment.
QUESTION
Node.js - Client to Server WebRTC with P2P
Asked 2021-Aug-26 at 04:13After looking to implement WebRTC with a Client to Server model (like Discord), I came to the conclusion that the way to do this is to have 2 clients - the server and client. Audio streams can be overlayed and sent back to the user in 1 single stream.
backend/server.js
1const clientPeer = new Peer({ initiator: true, wrtc });
2
3clientPeer.on('connect', () => console.log('hi client, this is server'));
4clientPeer.on('data', (data) => console.log('got a message from client peer: ', data));
5frontend/index.js
1const clientPeer = new Peer({ initiator: true, wrtc });
2
3clientPeer.on('connect', () => console.log('hi client, this is server'));
4clientPeer.on('data', (data) => console.log('got a message from client peer: ', data));
5serverPeer.on('connect', () => console.log('Connected to server'));
6serverPeer.on('stream', async (stream) => {
7 const video = document.createElement('audio');
8
9 ('srcObject' in video)
10 ? video.srcObject = stream
11 : video.src = window.URL.createObjectURL(stream);
12
13 await video.play();
14});
15How would I implement sending media streams between the client and server?
ANSWER
Answered 2021-Aug-26 at 04:13A possible solution can be: Create a MediaRecorder object, which can record the media streams on the client-side. This object emits data chunks over time. You can send these chunks via WebSocket to the server. On the server side, you can do what you want with the data chunks.
For more details, you can check this https://mux.com/blog/the-state-of-going-live-from-a-browser/.
https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder Another solution can be: Making a node.js application a PEER with WebRTC
