[FFmpeg-user] How to extract audio from video without re-encoding?
I want to extract audio from any arbitrary video file and have it save to an audio file without re-encoding and without me knowing ahead of time which audio file format to use. I don't know how to do it because ffmpeg requires an output filename with an extension, which means I have to specify the audio file format within the command. I want ffmpeg to choose the audio file format for me based on the type of audio embedded in the video, much like the -x parameter does in youtube-dl. How can I do this? Thanks. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

I consider M4A quite restricted: https://en.wikipedia.org/wiki/Comparison_of_video_container_formats#Audio_coding_formats_support Matroska (MKV) is much more flexible, as is ffmpeg's own NUT format.
