I have a video with some background music in it.
I wish to add a piece of spoken dialogue at a particular location in the video, such that the background music is lowered for the entire duration of the dialogue audio.
I found a similar solution using
sidechaincompress, which just works for mp3. I made some changes to it so that it includes the video too (
-map 0:v). However, now the audio is cut short as soon as the dialogue ends.

I have a HEVC encoded 4k Video captured from a Reolink IP-Cam with VLC Player 3.0.14. I want to extract each frame of the video but the encoding stops after only two frames. This also happens when I try to convert into another video format. This happens on Windows and Ubuntu with different ffmpeg versions.

MP4s may have an edit list which tell the player to construct a virtual playback timeline. Occasionally, this timeline can leave out frames needed to decode stream correctly, or the sync samples table may be wrong.
-ignore_editlist to demux the stream without any edits.

Try something like this:
This 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 a .m4s media fragment.
I created this public GitHub project to reproduce the issue in its entirety.
For example, here's the custom ChunkFragmentM4sBuilder.java class.
The first example using MP4 box works, insofar as I am able to generate an initializing MP4 + series of fragment M4s files which can then be concatenated to form a playable MPEG4 stream.
Note: it's a requirement for this use case that each media segment is encoded from an individually generated source segment, versus using a tool such as MP4Box to stream from a continuous audio source.
Attempts to manually build media segments via mp4parser are still failing overall, because the fragments written by my ChunkFragmentM4sBuilder.java used below are malformed. But I'm having a difficult time understanding how exactly they are malformed.
ANSWERAnswered 2021-Oct-23 at 13:07
test-java-mp4parser.mp4 is not empty but is invalid because:
sidxentry referenced size is wrong
tfhdis overriding the default sample description index (
trundoesn't specify the data offset
mdatAAC data starts with 8 zero bytes which cause the decoding to fail
The file plays with FFmpeg if these are fixed.
m4s segments listed are also malformed and don't seem to correspond to the concatenation result. For example the sequence number is used as the sample description index.
I would need to be able to seek to a position before playback of a video is started with JavaFx 16
When MediaPlayers seek() or setStartTime() is called before play() it is breaking video output and no frames are updated anymore (sound is still playing).
The duration of the video is known and not indefinite. No errors are printed by the listener nor any meaningful stalling (only sometimes in the beginning when video is loaded via https), but the same issue appears for local files as well. So I think this can be ruled out. I am building and running the app with Maven,
mvn clean javafx:run.
I tried to call those methods separately and also one after each other inside the ready listener and outside in the start method.
I am using JDK 11 (11.0.11+9-Ubuntu-0ubuntu2), maven 3.6.3 and openjfx 16 at GNU/Linux (Ubuntu 21.04)).
I assembled a minimal example and do I do anything wrong in the following code? Do you know how this could be handled or worked around? Thanks in advance.

This is a known bug, which is a regression bug introduced in JavaFX 14. It was resolved in JavaFX 17. The best fix is to change your JavaFX version to 17 (or later; 17 is the current version at the time of writing). If that is not possible for some reason, reverting to version 13 or earlier will work, though you will see longer wait times before the video is ready.

I have a video file in MP4 format which supposedly has a 720×576 resolution yet is 786 × 576 according to the Finder on Mac:
As part of this discussion here it's been pointed out to me that this may be because the file is PAL standard video, according to which this is the expected behaviour. I'd like to change this using ffmpeg so that the file actually is no longer PAL standard video but always only 720 pixels in width.
To do so, I've been pointed to this question to find the corresponding ffmpeg command. Yet when I try to run
ffmpeg -i weird_video.mp4 -vf "scale=iw*sar:ih,setsar=1" -crf 28 -c:a aac -b:a 80k -ac 1 -movflags +faststart h-264-out.mp4, I get an error message as the actual width of the video seems to be 785 and not 786 pixels as indicated by finder:

I need to trim some clips in the video, the best way I found (without unpacking frames, or trimming only the keyframe, although with the ability to do so without transcoding) I do not quite understand the meaning of such setpts, and ffmpeg writes that there is something wrong with ',', but nevertheless it works....

- h264_rkmpp appears to incorrectly have priority over the built-in FFmpeg H.264 decoder (named h264), so h264_rkmpp is being used by default.
- h264_rkmpp is having trouble decoding this video (I don't know why).
ffplay to use h264 instead:

You can use SoundHandler like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the SoundHandler component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
