For many uses, playing video while animations are running is pretty useful and it is also
considerably stressful for the GPU. I therefore tested a couple of cheap chips with the same
Qt/QML sample app. I created a small demo video comparing Qt on A31s and Raspberry Pi (PiOmxTextures):
In the demo, all the media (video and images) are 720p, and the output is 720p for A31s and
1080p for Raspberry Pi (16bpp). It is pretty hard to tell from the video, but Raspberry
seems to still be above A31s.
