gst-rtsp-server, appsrc/appsink and tee

[Eloi Bail]

I wrote a simple test application that use appsrc /appsink and tee without
a gst-rtsp-server context and can reproduce the issue.

In test.py in attachment, one of my tee branch is decoding and displaying
videotestsrc, the other tee branch is muxing the h264 streams into a file.

When running* ./test.py* I have my content displayed.
When running *./test.py --serialize, *the matroska file is correctly fed
but the video is never displayed.

I will investigate that further tomorrow. If someone could give me advice,
that would be great.

Thanks,

Eloi
