Hi,
We are trying to play video files on Wince 7 on Logic PD Zoom AM3517 EVM .
We have noticed that when we increase the video resolution for a given video file , the frame rate is dropping.
For eg: When we play a video of 320x240, 30 FPS video Its playing fine. However when we double the resolution of the video (i.e. 640x480, 30 FPS) it is playing slower than the normal speed (lower framerate) . (We tried playing those two videos on a desktop pc and couldnt find any drop in perfomance, so it is not an issue with the files themselves.)
We used Ceplayit for doing the playback. we tried the playback on the onboard LCD as well as on DVI screen on all possible resolution provided by the BSP in eboot. (The native resolution of the External DVI display is 1440 x900 , 60Hz).
Our requirement is to make an 800 x 600 , 30 FPS video run smoothly on an external 15" LCD display (native resolution 800 x 600) with Wince7 BSP.
We have tried the same using the Linux BSPs provided for the platform. Even though the playback perfomance is slighty better , we still observed a drop in frame rate.
So is it possible to acheive smooth playback for a 800 x600, 30 FPS video on AM3517 platform. What are the parameters that we can tweak to get a better perfomance?
