Series media: meson: vdec: Add VP9 decoding support | expand

Commit Message

Neil Armstrong March 4, 2020, 9:46 a.m. UTC 
The HEVC/VP9 aligns the plane stride on 32, so align the planes stride
for all codecs to 32 to satisfy HEVC/VP9 decoding using the "HEVC" HW.

This fixes VP9 decoding of streams with following (not limited) widths:
- 264
 -288
- 350
- 352
- 472
- 480
- 528
- 600
- 720
- 800
- 848
- 1440
