Hi Chris, Diego,
We met that problem. That happened because when CaptureFrame(
&capbuf_phyaddr) was called, that function returned but the returned buffer was
not filled up with an entire new frame. That means, the "top part" of the
buffer belongs to the current frame but the "bottom part" belongs to the old
frame. We overcame this by using the previous buffer (the buffer returned by
the previous call to CaptureFrame) for displaying / encoding when calling
CaptureFrame( &capbuf_phyaddr) for getting current frame.
Let us now if this can help.
Regards,
Viet Hoang.
