Dynamic volume mixing with FFMPeg

Asked 2021-Jun-01 at 15:46

I am streaming audio using FFMPeg and need to mix two audio sources using FFMpeg and set the volume level dynamically. I.e. once the stream starts, I need to be able update the ratio of the two volumes.

Currently, I have the volume mixing and streaming working using the CLI version of FFMPeg but the volume mix ratio is static.

Is there a way to dynamically set the volume ratio using the CLI tool? Perhaps something with an FFMpeg expression?

Or is using the API the only option? If so, can anyone point me towards an example of dynamically mixing audio? I haven't been able to find one.

Edit: here are the params I currently pass to mix audio. Again, this works fine, so not including the log as there is no error to fix. The question is how can I adjust the ratio of the amix mix after the process has launched. Willing to use the API if need be.

Commands

Some filters support commands which allow temporal control of some filter options. Not all filters have commands. Sometimes commands get added so always use a recent ffmpeg to take advantage of new features.
Refer to ffmpeg -filters and look for C next to the filter name, or view man ffmpeg-filters or FFmpeg Filters documentation and search for commands under each filter.
Not all options have a command equivalent.

(a)sendcmd and (a)zmq

asendcmd / sendcmd - does scheduled commands or interactive commands via interactive mode.
azmq / zmq - does interactive, on demand, live commands. To enable (a)zmq you need to install the libzmq library and headers and configure ffmpeg with --enable-libzmq.

Low latency video player on android

Asked 2021-May-20 at 11:24

I'd like to be able to stream the video from my webcam to an Android app with a latency below 500ms, on my local network.

I do not know a native low latency player in Android.
However you can use a WebView in Android Studio and use a player in the web.
With this solution I streamed the webcam of my pc to my phone (in the local network) with livecam.
They use websockets to transmit the video frame by frame, which is not ideal. With this method I had 370 ms of latency.

Reading strings and decreasing them

Asked 2021-May-14 at 20:12

I just have a simple question when dealing with text files: I have a text file and want to make a python program to read it and if it finds any number it replaces it by the number preceding it like if it finds 4 it replaces it with 3 so how can I do that?

The problem for me in this program is that python reads the numbers as strings, not integers, so it can't decrease or increase them.

How to create x264 RTSP server with OpenCV Python with GStreamer backend

Asked 2021-May-03 at 23:42

My goal is to create a RTSP server using OpenCV Python using the GStreamer backend. I have RGB images stored as OpenCV Mat, and I would like to create a VideoWriter which can write to a RTSP sink. The output video must be x264 encoded.

I believe this can be easily achieved using a GStreamer pipeline and providing the pipeline arguments to the VideoWriter constructor and then later pushing frames to the VideoWriter, but the issue is I have no experience working with GStreamer and I find it very confusing.

The answers I have found on SO are incomplete, use specific hardware decoders (ex for NVIDIA Jetson), or are overly complex. I'd like to find a more generic solution which works on CPU.

Figured it out myself with some debug assitance from @llogan.

So, it looks like VideoCapture exports frames with BGR format, thus the Red and Blue colors being switched out. In order to fix my issue all I had to do was to convert the frame from BGR to RGB using the OpenCV utility method:

Trying to remove every character inside brackets "[...]"

Asked 2021-Apr-12 at 13:59

I'm trying to find a way to detect and remove characters within a range of characters inside a string. Tried looping around and not much of a success and now experimenting for Regex.

So I'm supposed to input a filename e.g. [1080p]Godzilla.subs.mp4 or JohnnyEnglish_720[EnglishSubs].mp4 or [x264]psa_recording[1270x720].mp4

I'm supposed to remove all characters within the [] and output Godzilla.subs.mp4 or JohnnyEnglish_720.mp4 or psa_recording.mp4`

I think you're overcomplicating your regex. I think in this case a simple one like the following should work.
