Headline: Optimization of x264 for video conferencing system
Acceptance: User can use settings for x264 to implement real-time encoder
[yang.zhang - 31.Aug.2011]: the conclusion of the benchmark analysis was to disable some features of x264 to achieve real-time h.264 encoder. Now the performance of x264:
profile parameter
baseline PSNR: 37, bit rate: 900 kbps, frame rate: 21 fps
high PSNR: 36.4, bit rate: 700 kbps, frame rate: 20 fps
Related to the final optimization on the ARM platform - the estimated improvement of frame rate is about 10%. The performance improvement is not obvious, so it may be delayed.
