Buid Exoplayer with ffmpeg extension
22 février 2021, par Bhoomi KalavadiyaI'm making IP streaming android application. In which I'm using exoplayer 2.12.0. Input video is having mpeg-L2 audio layer codec which is not supported by exoplayer https://github.com/google/ExoPlayer/issues/6525. So i'm using ffmpeg extension to render audio.

I have followed https://github.com/google/ExoPlayer/tree/release-v2/extensions/ffmpeg steps to build ffmpeg extension with android-ndk-r21d-linux-x86_64 and FFmpeg-release-4.3.

Added code in the application

TrackSelector trackSelectors = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory()); RenderersFactory renderersFactory=new DefaultRenderersFactory(this,EXTENSION_RENDERER_MODE_ON,DEFAULT_ALLOWED_VIDEO_JOINING_TIME_MS); player = ExoPlayerFactory.newSimpleInstance(this, renderersFactory,trackSelectors);


Still audio is not coming and the log is as below

Here, With or without ffmpeg extension, I'm not getting audioEnabled log in Eventlogger.
Also after using ffmpeg audio render, I'm not getting it is being used or not.
Or am I missing some configuration of ffmpeg extension to Exoplayer ?

FFMPEG in thread error : Thread was being aborted
21 juillet 2018, par swabygwI’m using FFMPEG to convert video files from one file type to another. I do it via an ASP.NET web interface where a user can upload their file and the conversion happens in a .NET "thread", like this :
trd = New Thread(Sub(sender) TestSub(folder,interv,objCounter,fname,fversource,fverdest,fext,fhost))
trd.Priority = ThreadPriority.Lowest
trd.StartWhile the conversion is happening, I’m logging the progress of the conversion by using the FFMPEG "-progress" argument.
If I don’t use a thread, I get a complete log that looks like the output below. But when I run it in a thread, the conversion happens successfully still, but I get this error message from .NET : "Thread was being aborted." right after line #46...regardless of the file type, file size, etc., it always errors after line #46. I need to capture the rest of the output from the execution in the thread (just like when it was run outside of the thread). Can anyone help ?
P.S., I have tried extending the server timeout, like this (it didn’t help) : httpRuntime executionTimeout = "600", in the web.config file.
P.P.S, found something interesting. I’m using a StreamReader to capture the output, and I log each line of the StreamReader to an output file, like this :
Dim ffReader As StreamReader
prcFFMPEG.Start
ffReader = prcFFMPEG.StandardError
While Not ffReader.EndOfStream
strFFOUT = "Test:" & ffReader.ReadLine
LogConversion(fhost,"strFFOUT(ffReader.ReadLine): " & (strFFOUT).ToString)
End WhileHere’s the odd part : In the While/EndWhile loop, if I print out just "Test" instead of ffReader.ReadLine, it runs, I get a lot more lines, and the thread aborts but I see FFMPEG still running in Task Manager. If I leave it running in Task Manager and rerun the code with ffReader.ReadLine, it will print out everything with no errors/aborts. But, if I end the background task in Task Manager, I get the same problem and error again.
