Video player in 18.04 shows a psychedelic mixture instead of a clear video

I just installed Ubuntu 18.04 along with the restricted extras. I've also installed virtually all the GStream packages in an attempt to fix this problem. Whenever I try to play an mp4 I get a mixture of psychedelic colors. I can make out movement in the videos, but I cannot discern features. I do not have this problem with another Linux I installed.

My computer runs an AMD processor with R7 Radeon graphics.

Thanks for any help you can give.

Solution 1:

I had the same problem when playing a MP4 video, totem/gnome-videos displays a purplish corrupted video output and I have done the following:

From the terminal sudo apt-get remove gstreamer1.0-vaapi

I have done a test and yes, the problem has been fixed now I can see the video correctly.

So the problem is gstreamer1.0-vaapi

Best Regards,
