Description

I'm trying to join 2 rtp streams into a single video stream.
Both of the stream's content is mjpeg (rfc 2435).

How to reproduce:

ffmpeg -i rtp://192.168.1.1:54321 -i rtp://192.168.1.2:54321 -filter_complex "[0:v][1:v] overlay=10:10" -f mjpeg - | ffplay -f mjpeg -

It was reproduced on version 2.8.11 and 3.3.

The error messages I'm receiving:

  • "RTP: missed X packets"
  • "RTP timestamps don't match."
  • "Received packet without a start chunk; dropping frame."
  • "Missing packets: dropping frame"

Component: ffmpeg → undetermined
Version: 2.8.11 → unspecified

Please test current FFmpeg git head and provide the command line together with the complete, uncut console output to make this a valid ticket.
