I am generating HLS/fmp4 as follows: ffmpeg -hide_banner -loglevel warning -itsoffset 0.010666450 -i audio.121063.m4a -i video.242528.m4v -i video.141815.m4v -i video.84763.m4v -map 0:a:0 -map 1:v:0 -map 0:a:0 -map 2:v:0 -map 0:a:0 -map 3:v:0 -c:a copy -c:v copy -copyts -bsf:v setts=pts='not(not(N))*PTS' -var_stream_map "a:0,v:0,name:363591 a:1,v:1,name:262878 a:2,v:2,name:205826" -hls_flags single_file+independent_segments -hls_playlist_type vod -hls_segment_type fmp4 -hls_list_size 0 -hls_time 9 -hls_segment_filename hls/%v/fragmented.mp4 -f hls hls/%v/index.m3u8
The resulting HLS/fmp4 seems to be valid, but at least one player (hls.js) has a problem. The player believes the fmp4 file is mpegts because it sees the byte 0x47 appearing three times in the stream, with very specific offsets: - 0x47 @ i - 0x47 @ i + 188 - 0x47 @ i + 376 This does not happen in most cases, just in one unlucky case (with specific media files). I have 2 questions about this: 1. Is there an ffmpeg command that can insert short (meaningless) byte sequences to prevent the mpegts pattern (described above) from appearing? 2. If not, I'd like to build my own. Is there a particular escape sequence that allows one to insert a meaningless byte into the stream of mp4 bytes? _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
