Subject: [PATCH] media: rp1: cfe: Improve link validation for metadata
|
|
|
|
Improve the link validation for metadata by:
|
|
- Allowing capture buffers that are larger than the incoming frame
|
|
(instead of requiring exact match).
|
|
|
|
- Instead of assuming that a metadata unit ("pixel") is 8 bits, use
|
|
find_format_by_code() to get the format and use the bit depth from
|
|
there. E.g. bit depth for RAW10 metadata will be 10 bits, when we
|
|
move to the upstream metadata formats.
