Hello, I'm using DM642 to process video. However, I found that the frames were captured as YUV422 format by the chip on my DM642 EVM. Then the frames were transformed to be RGB565 format and put into an output buffer. I now utilize the image data in the output buffer to perform desired image processes based on RGB color model. I wonder if the flow is appropriate? Or I'm supposed...

Hi, all Recently, I develop Mpeg4 decoder by using DM642. Video bitstream was transfered from PC throuth PCI to SSDRAM in dm642. The bitstream was a ".avi" file and is of PAL type video. The frame is of 352*288 pixels(CIF type). As we know, to correctly display the video, the output frames should be in speed of 25 frames per second. While the frame rate is a little faster than 25 frames per s...
