Package: ffmpeg
Version: 5.1.4-0
Release: Bookworm
ffmpeg terminates (without error) after a couple of frames when trying
to download, copy or transcode an HLS/fMP4 stream.
HOWEVER, the same ffmpeg command lines work fine on HLS/TS streams.
I am generating the streams using the program `go2rtc` on an RPi5
Note that the problem seems to be *specific* to Debian Bookworm.
Specifically the same HLS/fMP4 stream and ffmeg command lines:
- Fail on:
x86/Debian/Bookworm - ffmpeg 5.1.4
RPi5/Bookworm - ffmpeg 5.1.4
- Succeed on:
RPi4/Buster - ffmpeg 4.1.11
x86/Debian/Bullseye - ffmpeg 4.3.6
x86/Debian/Trixie - ffmpeg 6.1.1
x86/Ubuntu 18.04 - ffmpeg 3.4.11
x86/Ubuntu 22:04 - ffmpeg 4.4.2
x86/Ubuntu 24:04 - ffmpeg 6.1.1
Win11/Cygwin - ffmpeg 4.0.2
i.e., versions (on multiple platforms) before and after 5.1.4 succeed.
Using even this simple line fails where the stream is HLS/fMP4
# ffmpeg -re -i "http://mypi:1984/api/stream.m3u8?src=picam_h264&mp4";
output.m3u8
But succeeds when the stream is HLS/TS
# ffmpeg -re -i "http://mypi:1984/api/stream.m3u8?src=picam_h264"; output.m3u8
Any ideas on what is "special" about Bookworm/ffmpeg-5.1.4 that fails
but just about any other version seems to succeed
