About UV wrong

Is this the decoded image or live capture preview

Thanks very much!

Decode image.

In AlgLink_ScdAlgCopyFrame,

pFrame->addr[0][0] and pFrame->addr[0][1] is really  all data?

or pFrame->addr[0][1]  may be not right if image no detect changed, right?

Check if the preview image from capture is showing artifacts . This looks like reference buffer size for decoder chroma buffer is wrong or the decoder output buffer is being corrupted. If you are using the DVRRDK without any modification this will not occur. Undo all your changes and check if you see the issue. Try creating the decoder for larger resolution and tiled output. I don't think this has got anything to do with ScdCopyFrame.

Thanks. My step is:

1.  pBuffer = Utils_memAlloc(704*576*3,  SharedRegion_getCacheLineSize(SYSTEM_IPC_SR_CACHED) );

2. Encode pFrame->addr[0][0] and chroma data to pBuffer

3. memcpy(pOoutBuffer, pBuffer, fillLenth)

is it right? or is it cause that effect?

Only chroma data wrong. 

why? 

who can help me?
