[PATCH 0/2] media: verisilicon: fix reference padding issue

[Benjamin Gaignard]

Hantro hardware is splited into two parts: the decoder which produce
tiled pixels formats and the post-processor which produce raster pixels
formats.
When post-processor is used the selected pixels format may not have the
some padding/stride than the decoder output pixels format. This led to
miscomputing chroma and motion vectors offsets so data are overlapping.
This series introduce a reference pixels format that decoder use to
compute the various needed offsets and size.

With this series Fluster for VP9 tests is now 207/305 vs 145/305.
HEVC test score isn't impacted by these patches (still 141/147).
