-Subject: [PATCH 08/18] media: rkvdec: h264: Do not override output buffer
- sizeimage
-
-The output buffer sizeimage is currently forced to 2 bytes per pixel, this
-can lead to high memory usage for 4K content when multiple output buffers
-is created by userspace.
-
-Do not override output buffer sizeimage and let userspace have control of
-output buffer sizeimage by only setting sizeimage if none is provided.
