Coreplayer Benchmark Testing

Hello All,

I decided to start a thread about benchmarking on the TP2. Below is a Free and Legal video to test for benchmarking. If we all use the same video, the tests will be more replicable. Its an 890MB, 1920x1080p video. Suggestions/Comments are welcome to improve this thread. Make sure you are not running other programs on the TP2 at the same time when benchmarking. Thanks.

Coreplayer benchmark of video.

-------------------------------------------------------------
Results:Preliminary Results, I ran many benchmarks but I haven't organized it well.
Note: % refers to playback speed. As long as you are over 100% playback speed in a benchmark, the video will run smoothly.

Quick Conclusion:

MPEG-4 FFmpeg is hardware decoded. So far I have gotten a bitrate of 1160kbits (1000kbits + 160kbits AAC) at a resolution of 720x400. Playback was 108%. As I decreased the resolution, the playback speed would go up only slightly. I am going to try 800x448 and max out the bitrate to see what I can get.

MPEG-4 Xvid. Not sure if it is hardware decoded. Haven't done extensive testing. Plays better than h.264 does.

h.264 is software decoded. I couldn't get 560x315 running better then 91%. 480x270 was 118%.

that's too bad, I don't have many files in H.264 but I think they're all mkv. It's too bad that I have to convert them. I've been opening some ogm files lately that are encoded in Divx which seem to work well... I can give more precise stats later.

I have an iPod touch so I am used to converting. Converting can have some benefits of better battery life. By using the format with the least resources, you can get a significant boost in video playback time.

Bump...

The OP has valuable information in the conclusion.
