Description

Summary of the bug:

Using static build 2.8.5 I can happily send out a multicast stream using rtp_mpegts muxer, but receiving this same stream doesn't work properly.
I have tried the following receiving options :
./ffmpeg -i rtp://239.10.10.10:5000 gives me these errors:

How to reproduce:

Create your RTP_MPEGTS source from a local udp multicast:

'''./ffmpeg -i udp://238.44.100.1:5000 -c:v copy -c:a copy -f rtp_mpegts rtp://239.10.10.10:5200'''

Am i missing something here ? FFMPEG still doesn't seem to demux RTP mpegts packets properly.
Since there was an RTP_MPEGTS muxer added in 2.6, can this not be brought to the demuxing side ?

Thanks

  • Component changed from ffmpeg to undetermined
  • Keywords rtp added; rtp_mpegts removed
  • Priority changed from important to normal

Please test current FFmpeg git head, please use -f lavfi -i testsrc -f lavfi -i sine as source and please provide command lines including complete, uncut console output to make this a valid ticket.

Hiya.

As requested, i have used the latest git head, and reran the tests as follow:

  • Test 1:
    • Use -f lavfi -i testsrc -f lavfi -i sine as a source + generate -f rtp_mpegts output.
    • Receive -i rtp:// from the sender and output to /dev/null

This test shown positive results, i was not getting any issues on the Receiver side.

  • Test 3:
    • On the Receiver side, Use live RTP MPEGTS source from a 3d party encoder + output to /dev/null

This test shows us that the issue is not only with receiving RTP MPEGTS originating from FFMPEG, but also from other 3d party encoders.
