RTOS/TDA2x get encoder buffer issues

Hi all,

    I am facing issues in dump data to SD card when i run my usecase on TDA2x EVM.

    My usecase like this,

     Capture->dup->Enc->Dec->Merge->Display

    Now I want to dump encoder data to SD card. So I use theSystem_getLinksFullBuffers to  get the buffer between Enc&Dec Link after start the app.

    the issues is:

    1.I found the function sometimes can not get buffer data. It will return with numBuf = 0;

    2.The SD write speed is to slow(5MBytes/s). How can i improve the speed.

    3.I found the MJPEG data dump to SD is the same despite the data size is 1024*720 or 960*540.

    4.If i dump h264 data to SD card. VLC can not play the video.

Regards,

Zhang
