Summary of the bug:
See a partial fix (12 years ago) here: https://trac.ffmpeg.org/ticket/2230
This only provided a fix for metadata flags
-service_name
-service_provider
to be passed on to the chained mpegts muxer
but it did not pass on the flags for
-mpegts_pmt_start_pid or
-mpegts_start_pid
You can obtain a copy of big buck bunny here:
https://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_320x180.mp4
What I want:
{{{
-mpegts_pmt_start_pid and/or -mpegts_start_pid flags to be passed on to
the mpegts muxer
Then, if you use TSDuck tsanalyze tool (or another mpegts analyzyer) on
.ts segment files you should see
tsanalyze output of final file:
|===========================================================================|
| PID: 0x01E0 (480)
PMT|
}}}
What I get:
{{{
|===========================================================================|
| PID: 0x1000 (4096)
PMT|
}}}
How to reproduce:
{{{
% ffmpeg -i BigBuckBunny_320x180.mp4 -t 24 -start_number 1 -hls_time 6
-segment_time 6 -hls_list_size 0 -hls_segment_filename
BigBuckBunny_%05d.ts -hls_playlist_type vod -sc_threshold 0
-mpegts_pmt_start_pid 480 -mpegts_start_pid 481 -f hls BigBuckBunny.m3u8
}}}
