I have now also tried on a Raspberry-Pi5B, which runs the fully updated most recent operating system PiOS (Debian based, I guess). I did a test with this: - sudo apt update (showed 190 packages to upgrade) - sudo apt full-upgrade (this upgraded ffmpeg too) Then I made a copy of my stream download script where I added the extra parameters to the ffmpeg call at the end just before the output file name: -movflags +frag_keyframe+hybrid_fragmented Everything else untouched. Then I used the script to download a 30 s test sequence. But then ffmpeg threw and error and quit with this at the end of the run: [mov/mp4/tgp/psp/tg2/ipod/ismv/f4v muxer @ 0x55559f9f4fb0] [Eval @ 0x7ffffa717520] Undefined constant or missing '(' in 'hybrid_fragmented' [mov/mp4/tgp/psp/tg2/ipod/ismv/f4v muxer @ 0x55559f9f4fb0] Unable to parse option value "hybrid_fragmented" [mov/mp4/tgp/psp/tg2/ipod/ismv/f4v muxer @ 0x55559f9f4fb0] Error setting option movflags to value +frag_keyframe+hybrid_fragmented. Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument Error initializing output stream 0:0 -- So clearly this version of ffmpeg does not support the argument. Output starts with this: ffmpeg version 5.1.6-0+deb12u1+rpt1 Copyright (c) 2000-2024 the FFmpeg developers built with gcc 12 (Debian 12.2.0-14) So is there a way (not involving self-compiling ffmpeg) to get the latest version on board? Just wait some weeks perhaps? -- Bo Berglund Developer in Sweden _______________________________________________ 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".
