System info

Operating System:Rocky-8.4-x86_64 Shaka Packager Version: v2.6.1

Issue and steps to reproduce the problem

Situation 1. I use ffprobe to view the content of udp, and I see three streams. When I use packager -dump_stream_info, I only see one stream.

/opt/asorigin/web/bin/ffprobe 'udp://224.1.1.1:5002'

Input #0, mpegts, from 'udp://224.1.1.1:5002':
  Duration: N/A, start: 49.824100, bitrate: N/A
  Program 1 
    Stream #0:0[0x44]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv, bt470bg, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
    Stream #0:1[0x32](zho): Audio: eac3 (EAC3 / 0x33434145), 48000 Hz, stereo, fltp, 128 kb/s

Condition 2. Transfer files directly, it will appear「 Ignore unsupported MPEG2TS stream type 0x87」 /opt/asorigin/web/bin/packager \ 'in=/opt/mv/eac3.ts,stream=0,output=/opt/asorigin/content/vod/nfs/s05/video/video_init.mp4'

Condition 3. But I see that the file shows that it can be output.

question:

  1. I would like to know that shaka packager, mpeg2-ts support output format is EAC3, but that is, do I want to use iso-bmff format for input?
  2. How to generate data in iso-bmff format?
  3. Does mpeg2-ts currently support input?

I would like to know that shaka packager, mpeg2-ts support output format is EAC3, but that is, do I want to use iso-bmff format for input?

Yes, the only supported input format for now is ISO-BMFF.

How to generate data in iso-bmff format?

You can use FFmpeg to transmux your input to iso-bmff format.

Does mpeg2-ts currently support input?

Yes, but not with EAC3 yet. If you are interested in helping the project, you are welcome to work on it and submit a PR to us.
