[GStreamer (GNOME Bugzilla)]

Hi Sebastian,

we have webrtc rtp streams going from camera/desktop -> chromium (chrome 58) ->
janus -> gstreamer and compose a video stream in gstreamer which we are
streaming via rtmp.

The example video stream originated from a logitech camera.

I have attached a dot graph png so you can see the pipeline.

vpxdec = Gst.ElementFactory.make("vp9dec")
# vpxdec.set_property("post-processing-flags", 0x00000003);
vpxdec.set_property("post-processing", True)

Without the post-processing it works great.

I also tried to set post-processing-flags to 0x00000003 vs. the default. Both
exhibited the error.

The log file gets to big to be attached so I gzipped it and put it on my google
drive:

thank you,
Florian
