Hi

I am trying to display a RTSP stream from two different onvif cameras which
I start with

gst-launch-1.0 rtspsrc --gst-debug=3 user-id="admin" user-pw="admin"
location="rtsp://192.168.42.3:554/1/h264major" ! rtph264depay ! h264parse
!  avdec_h264 ! autovideosink  # (with and w/h264parse)

The output shows a repeating

0:00:05.663361958 11664 0x7f44600014a0 WARN            videodecoder
gstvideodecoder.c:732:gst_video_decoder_setcaps:<avdec_h264-0> Subclass
refused caps

Both streams can be displayed with mplayer and vlc

Any advice how to debug the problem?

Best
Stefan

PS:

   - Ubuntu 16.04
   - Gst-Build (1.14 branch)
   - FFMPEG (release/3.4 branch, newer version failed to build)
