--- Comment #40 from Arnaud Vrac <rawoul at gmail.com> ---
waylandsink does not support padded SHM buffers, yet it still gets padded
buffers from libav based decoders. The result on screen is shifted Y, U and V
planes which doesn't look very good.

waylandsink could support those using the wp_viewport extension by applying
cropping on the buffer. But until this is the case, the buffer pool negotiation
shouldn't result in padded buffers.

Note that I did apply the patch on weston so that GL texture uploads use the
correct stride for U and V planes
