[PATCH v3,16/21] media: medkatek: vcodec: support one plane capture buffer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The capture buffer has two planes for format MM21, but user space only
allocate secure memory for plane[0], and the size is Y data + uv data.
The driver need to support one plane decoder for svp mode.
