Never tried this, did not even know it existed! As long as this -f just ordinary avformat muxer you probably can copy your favourite ffmpeg video/audio profiles with new .seg name and put "segmented" at very first line there , where "mov" or "matroska" or other format name was, and add rest of options. And add pattern (%02d) into name just as with ffmpeg-based image lists. I'll try this with termux's version, but I do not have audio here so it will be incomplete. > Terje J.
