DM388: How to flush the YUV buffers ?

Hi All,

While running the capture display demo on dm388evm with 3.8.1 ipnc sdk  the buffers are not flushed , I can see the repeated frames even after disconnecting the input while running the demo.How to flush the YUV buffers so that i should see a blank screen when input is disconnected in between the demo.

I tried to memset the yuv frames to 0x80 in CaptureLink_drvPutEmptyFrames.

for (frameId = 0; frameId < pFrameList->numFrames; frameId++)
 {
            pFrame = pFrameList->frames[frameId];
            size = Utils_getBufferSize();// This one returns the size of the frame which is used while allocating the YUV frame buffer for each frame.
            memset(pFrame->addr[0][0], 0x80, size);

}

Thanks
