Playing .h264 low resolution movie on a HD display through HDMI port. I see the movie gets automatically scaled to full screen and I guess OpenMAX is responsible for that. So, I assume GPU resources are being used to zoom while the movie plays.
If my intro is correct, what does it happen if I scale the movie in advance with FFMpeg for example?
a) visual appearance improves/degrades
b) playing the FFMpeg-scaled movie reduces/leave unchanged GPU utilization
