media: uapi: move VP8 stateless controls out of staging

2021-03-22T08:52:12+00:00

Until now, the VP8 V4L2 API was not exported as a public API, and only defined in a private media header (media/vp8-ctrls.h). The reason for this was a concern about the API not complete and ready to support VP8 decoding hardware accelerators. After reviewing the VP8 specification in detail, and now that the API is able to support Cedrus and Hantro G1, we can consider this ready.

media: vp8: Rename V4L2 VP8 specific macro to V4L2_VP8_

2021-03-22T08:51:39+00:00

Before we move the VP8 controls to a stable public header, rename this macro so it's clearly V4L2-specific. Signed-off-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: uapi: Move the VP8 stateless control type out of staging

2021-03-22T08:50:57+00:00

Move the VP8 stateless control types out of staging, and re-number it to avoid any confusion. Signed-off-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: uapi: Move parsed VP8 pixel format out of staging

2021-03-22T08:50:38+00:00

Since we are ready to stabilize the VP8 stateless API, move the parsed VP8 pixel format. Signed-off-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: uapi: vp8: Add proper kernel-doc documentation

2021-03-22T08:50:17+00:00

In preparation for making the interface public, document all the structures. Signed-off-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: uapi: vp8: Rename v4l2_vp8_loopfilter to v4l2_vp8_loop_filter

2021-03-22T08:49:48+00:00

Rename to struct v4l2_vp8_loop_filter, which is closer to the VP8 syntax. This change is only cosmetics, but since this API is exposed to userspace, it's worth the trouble to get it consistent. Signed-off-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: uapi: vp8: Remove "header" from symbol names and macros

2021-03-22T08:49:29+00:00

It doesn't seem to add any clarity to have a "header" suffix in controls, struct names and flags. Since this just makes names too long without any benefit, just drop it. Signed-off-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: Rename stateful codec control macros

2020-12-03T11:27:32+00:00

For historical reasons, stateful codec controls are named as {}_MPEG_{}. While we can't at this point sanely change all control IDs (such as V4L2_CID_MPEG_VIDEO_VP8_FRAME_HEADER), we can least change the more meaningful macros such as classes macros.

media: uapi: Expose VP8 probability lengths as defines

2020-12-03T06:42:54+00:00

These values will be used by various drivers implementing the VP8 stateless API. This had been suggested by Ezequiel Garcia for the Cedrus VP8 driver. Signed-off-by: Emmanuel Gil Peyrot Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
