Is it possible to not decode the audio samples and just mux the audio sample after getting it from the demux Please let me know if there is a sample example for that available Really appriciate your help -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/3107#comment:7> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
