[XviD-devel] encoding xvid (2)

Hello,

I'm not quite sure about the stride value. The documentation 
'xvid-decoding.txt' says thats the difference between the memory 
address of the first pixel and the address of the first pixel of the 
next row is the stride value. The next sentence is when the image is 
one big block, then 'stride=width'.

So I think I have to use 'stride=width', but the memory difference 
would be in XVID_CSP_RGB32 would be 4 times the width. I tried both, 
'stride=width' gives the strange image and with 'stride= 4*width' my 
app crashes.

I think there is no stride value for encoding, isn't it?

Regards
Christoph Nägeli
