Error ingesting stream with DVBSub subtitles from a multicast source

[laxmipk]

System info

Operating System: macOS Ventura 13.5
Shaka Packager Version:shaka-packager:latest

Issue and steps to reproduce the problem

Deployed ShakaPackager using docker from link "https://shaka-project.github.io/shaka-packager/html/docker_instructions.html"

docker run -v /Users/userabc/Documents/Demo/shaka-packager/media/:/media -it --net=host --rm google/shaka-packager

Packager Command:

Following command is executed in docker

packager
'in=udp://239.0.0.1:5004,stream=audio,init_segment=audio_init.mp4,segment_template=audio$Number$.m4s'
'in=udp://239.0.0.1:5004,stream=video,init_segment=h264_360p_init.mp4,segment_template=h264_360p_$Number$.m4s'
--protection_scheme cbcs
--enable_raw_key_encryption
--keys label=:key_id=33333333333333333333312300004444:key=15cc53b18d424690a1021b3b8fb05212
--protection_systems Widevine
--mpd_output h264.mpd_

-------------Extra Step--------------

1. UDP multicast is created from the mac host system by running vlc streaming service in loop "udp@239.0.0.1:5004
   alias vlc='/Applications/VLC.app/Contents/MacOS/VLC'
   vlc tears-of-steal-teaser-1280-720.mp4 --sout="#std{access=udp, dst=239.0.0.1:5004}" --loop
2. Shaka packager docker is created in the same macbook host, network is mapped with "--net=host" as mentioned in guide
3. "docker ps" command gives docker running status without any open port as below

-------------Expected Result should be ---------

It should package the live udp multicast stream on 239.0.0.1:5004

-----------------But the Result is as per below----------

Packaging is not done, output is stuck over initialising Demuxer, Please kindly help to fix this issue.

Hello,

I have the same problem if DVBSub subtitles are in Multicast source. When I block the subs it starts working:

packager in=udp://239.239.239.239:1234?reuse=1 --dump_stream_info [0821/115802:INFO:demuxer.cc(89)] Demuxer::Run() on file 'udp://239.239.239.239:1234?reuse=1'.
