For me Gstreamer is a science in itself and I hope that you succeed.

Today I changed my 2nd PC (same hardware except CPU and same Mint) from 
stable to master and got the same scrambling with MediaView.

My first PC has a i5-3470/ Intel® HD Graphics 2500 and the 2nd a 
i7-3770/ Intel® HD Graphics 4000 and I use no graphics card.

When I played the video with GStreamer by command line ...

gst-launch-1.0 playbin 
uri=https://files.edge.network/misc/avi/file_example_AVI_640_800kB.avi

or any other video player the video was displayed correctly.

As an experiment I removed the gstreamer1.0-vaapi package on my 2nd PC 
and the scrambling of the MediaView was gone(!)

What does this mean in general and for the Gambas MediaView control?

Best regards

Claus
