-Subject: [PATCH] media: v4l2-mem2mem: add stateless_(try_)decoder_cmd
- ioctl helpers
-
-Commit bef41d93aac64b54c3008ca6170bec54f85784f5 upstream.
-
-These helpers are used by stateless codecs when they support multiple
-slices per frame and hold capture buffer flag is set. It's expected that
-all such codecs will use this code.
