Update test file that seems to have accidentally worked as ffmpeg might have bug related to the global_sidx option where offset ends up wrong when content if shifted. At least with 9.0.1 this seems to produce a broken file: $ ffmpeg -y -f lavfi -i testsrc -c:v h264 -f mp4 -movflags +global_sidx+frag_keyframe+empty_moov -t 100ms test.mp4 $ ffprobe -i test.mp4 ... [h264 @ 0x9ed048380] Invalid NAL unit size (1953658222 > 2992). ...
