Python example of loading the video file

I generated following files:

gst-launch-1.0 videotestsrc num-buffers=100 ! videoconvert ! matroskamux !
filesink location=raw.mkv

gst-launch-1.0 videotestsrc num-buffers=100 ! videoconvert ! qtmux ! filesink
location=raw.mov

gst-launch-1.0 videotestsrc num-buffers=100 ! videoconvert ! avimux ! filesink
location=raw.avi

They all contain raw video streams and are playable by Totem / gst-play.

GES cannot link the pipeline due to demuxing errors:

MKV

(GError('GStreamer encountered a general stream error.',),

AVI

(I will provide a full backtrace soon, since I don't have debug symbols)
