VERSION: ffmpeg version 4.4 | Windows & Linux
The HLS encoder (used with fmp4 segmenting) began generating invalid
initialization segments consisting of 5 boxes (ftyp, moov, sidx, moof, &
mdat) with the latest release -- and an invalid first data segment
consisting of a single styp box with no data.
Version 4.3 and the dash encoder generate an initialization segment with a
single ftyp and moov box, as expected.
Here is sample command that exhibits the behavior:
ffmpeg.exe -i "any.mp4" -y -an -codec:v libx264 -profile:v baseline -level
3.0 -b:v 1000k -s 960x540 -force_key_frames "expr:gte(t, n_forced * 2)"
-deinterlace -flags +cgop -hls_init_time 0 -hls_time 4 -hls_list_size 0
-hls_segment_filename %06d.m4s -hls_segment_type fmp4
-hls_fmp4_init_filename init.m4s -hls_flags
+independent_segments+temp_file -hls_playlist_type event -f hls
"output.m3u8"
