Attachment: Bug 1409105 - Downsample av1 images unconditionally.

Adding partial support for 10/12-bit video images seems to have
broken the native pixel-stride support we were using to pass
8-bit AV1 frame data formatted in 16-bit pixel values, resulting
in vertical green lines.

Revert to the earlier behaviour of always downsampling to 8 bit data.
This is slower for the demo stream, but at least displays correctly.
