Bug 1409105 - Downsample av1 images unconditionally. r=kinetik
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.
