Hi guys! We're developing a DGA program that render full screen at 1280x1024 16
bpp 15fps the video image read from a sony camera, but we're experiencing
tearing artifacts during rendering. This is a part of the code that copies the
data to the frame buffer:
void CAM_APP::DisplayImage_NoPartial(unsigned char* offset)
{
register int j;
register unsigned long caddr = (unsigned long) offset;
for(j=0; j<iSize; caddr+=2,j++){
*( (unsigned short*) caddr ) = sTable[g_pBuf[j]];
}
}
Where the offset is the start of the buffer destination, and g_pBuf is the data
captured from the camera. we've tried copying the data during vertical resync
but we're still experiencing tearing on the image. We're using an AMD gx2 geode
processor w/ 128 mb ram and 8mb vram. I would like to ask your help in removing
the tearing artifacts. Thanks.
