[XviD-devel] RE: possible vfw YV12 stride bug

[Klaus Post (KPO)]

Hi!

Yes.  I posted a (proper) fix at doom9 for Koepi.

- See:
http://forum.doom9.org/showthread.php?s=&threadid=70379&perpage=40&pagen
umber=2  - post #4 on that page.

I also set the UV-planes for proper alignment, and added the same code
for the decoder. I don't know if setting stride for the other planes
have any effect, but everything seem to work nicely now.

Can someone please commit the following? Change:

	if (frame.input.csp == XVID_CSP_I420 || frame.input.csp ==
XVID_CSP_YV12)               
		frame.input.stride[0] = (frame.input.stride[0]*2)/3;

to:

	if (frame.input.csp == XVID_CSP_I420 || frame.input.csp ==
XVID_CSP_YV12)
		frame.input.stride[0] = ((icc->lpbiInput->biWidth + 3) /
4) * 4;

Klaus Post suggested something similar in this thread, but left out the 
"* 4" at the end.
