Specified MPEG-TS mpegts_pmt_start_pid is not written to HLS(-ssegment) segments

[adamvaul]

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 -hls_playlist_type vod -sc_threshold 0 -mpegts_pmt_start_pid 480 -mpegts_start_pid 481 -f hls BigBuckBunny.m3u8

Your command uses the HLS muxer (-f hls), for which you have to specify
-hls_segment_options mpegts_pmt_start_pid=X:mpegts_start_pid=Y to pass on the values

Thank you so much. I will try this!
