Images and minimal player

Using master on raspbian, RGB pngs don't display, there is just a black screen.

Attachment zip includes minimal python player and the two png files that demonstrate the issue.

Also reproducible with videotestsrc ! video/x-raw,format=RGB ! glimagesink on the RPi but not on my linux desktop.
Comment 4 Stuart Axon 2016-12-16 09:49:49 UTC 
This may explain why I couldn't display any jpegs on the Pi.
Comment 5 Stuart Axon 2016-12-16 13:06:48 UTC 
I've made a test program that demonstrates this and other bugs available here

    gl/format: use the unsized format for RGB on GLES2
    
    In GLES2 GL_RGB8 doesn't exist so we cannot use it, use GL_RGB
    instead.
