Created an attachment (id=33067)
 --> (http://bugs.winehq.org/attachment.cgi?id=33067)
This is a byte dump of a frame of data.

Obsoleting 33066 attached the wrong file.

This is a byte dump for the start to the end of a frame.

After looking at the data there is this data doesn't match what would would be
expected for a YV12 buffer. The values being passed to the conversion function
show the image width to be 704 and image height to be 576. However the byte
dump clearly shows that data is 352x240 the input stride lenght is correct and
the output stride length is as expected 2816 (704*4) since the RGB data is 4
bytes. This issue now is where is the U and V data? It is suppose to come after
the Y data. There should be 352*240 of Y bytes, and (352*240)/4 U and
(352*240)/4 V bytes for color.
