ffmpeg error "Could not write header for output file #0 (incorrect codec parameters ?) : Operation not permitted Error initializing output stream 0:0"
27 juillet 2022, par DevSharmaI am running FFmpeg in my app and specifically in "Android 11" I am getting this error from several users


I have researched a lot but no solution found.


I thought there is something wrong with the codec parameter that is being passed since it is saying "incorrect codec parameters" but most of the parameters looks good.


also verified if all the required file permission are granted and those are good too


now I m unable to find the problem,


please help, thanks

8 avril 2021, par Tommy KhumargaBelow is my ffmpeg command :


-y -i vidInput.mp4 -vcodec mpeg4 -b:v 1000k -b:a 48000 -preset ultrafast vidOutput.mp4


And the result is :


[Mon Jul 06 2020 20:42:08.171] LOG Unrecognized option 'preset'.
[Mon Jul 06 2020 20:42:08.172] LOG Error splitting the argument list:
