Subject: [PATCH v3 10/10] media: rkvdec: h264: Support High 10 and 4:2:2 profiles
Add support and enable decoding of H264 High 10 and 4:2:2 profiles.
Decoded CAPTURE buffer width is aligned to 64 pixels to accommodate HW
requirement of 10-bit format buffers.
The get_fmt_opaque and valid_fmt ops is implemented to select a CAPTURE
format suited for the provided SPS control.
Signed-off-by: Jonas Karlman <jonas@...boo.se>
---
v3:
- Add get_fmt_opaque ops, the expected pixelformat is used as opaque
- Add new valid_fmt ops that validate pixelformat matches opaque
- Update H264_PROFILE control max value
