media: v4l: add I / P frame min max QP definitions

2019-04-22T14:25:36+00:00

Add following V4L2 QP parameters for H.264:
* V4L2_CID_MPEG_VIDEO_H264_I_FRAME_MIN_QP
* V4L2_CID_MPEG_VIDEO_H264_I_FRAME_MAX_QP
* V4L2_CID_MPEG_VIDEO_H264_P_FRAME_MIN_QP
* V4L2_CID_MPEG_VIDEO_H264_P_FRAME_MAX_QP

These controls will limit QP range for intra and inter frame,
provide more manual control to improve video encode quality.

media: vicodec: Introducing stateless fwht defs and structs

2019-03-25T18:02:30+00:00

Add structs and definitions needed to implement stateless
decoder for fwht and add I/P-frames QP controls to the
public api.

media: v4l2-ctrl: Add control for h.264 chroma qp offset

2019-01-16T19:03:19+00:00

Allow to add fixed quantization parameter offset between luma and
chroma quantization parameters. This control directly corresponds
to the chroma_qp_index_offset field of the h.264 picture parameter
set.

media: v4l2-ctrl: Add control to enable h.264 constrained intra prediction

2019-01-16T19:02:14+00:00

Allow to enable h.264 constrained intra prediction (macroblocks using
intra prediction modes are not allowed to use residual data and decoded
samples of neighboring macroblocks coded using inter prediction modes).
This control directly corresponds to the constrained_intra_pred_flag
field in the h.264 picture parameter set.

media: mpeg2-ctrls.h: move MPEG2 state controls to non-public header

2018-12-05T18:06:31+00:00

The MPEG2 state controls for the cedrus stateless MPEG2 driver are
not yet stable. Move them out of the public headers into media/mpeg2-ctrls.h.

Eventually, once this has stabilized, they will be moved back to the
public headers.

Unfortunately I had to cast the control type to a u32 in two switch
statements to prevent a compiler warning about a control type define
not being part of the enum.

media: v4l: fix uapi mpeg slice params definition

2018-11-06T10:07:53+00:00

We get a headers_check warning about the newly defined ioctl command
structures:

./usr/include/linux/v4l2-controls.h:1105: found __[us]{8,16,32,64} type without #include 

This is resolved by including linux/types.h, as suggested by the
warning, but there is another problem: Three of the four structures
have an odd number of __u8 headers, but are aligned to 32 bit in the
v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte
for each one. To solve that, let's add explicit padding that can
be set to zero and verified in the kernel.

v4l2-controls: add a missing include

integer types is missing:

media: v4l: Add definitions for MPEG-2 slice format and metadata

2018-09-24T13:54:21+00:00

Stateless video decoding engines require both the MPEG-2 slices and
associated metadata from the video stream in order to decode frames.

This introduces definitions for a new pixel format, describing buffers
with MPEG-2 slice data, as well as control structure sfor passing the
frame metadata to drivers.

This is based on work from both Florent Revest and Hugues Fruchet.

media: v4l2-ctrl: Add control for VP9 profile

2018-07-04T13:32:22+00:00

Add a new control V4L2_CID_MPEG_VIDEO_VP9_PROFILE for VP9 profiles. This control
allows selecting the desired profile for VP9 encoder and querying for supported
profiles by VP9 encoder/decoder.

Though this control is similar to V4L2_CID_MPEG_VIDEO_VP8_PROFILE, we need to
separate this control from it because supported profiles usually differ between
VP8 and VP9.

media: v4l2-ctrl: Change control for VP8 profile to menu control

2018-07-04T13:28:38+00:00

Add a menu control V4L2_CID_MPEG_VIDEO_VP8_PROFILE for VP8 profile and make
V4L2_CID_MPEG_VIDEO_VPX_PROFILE an alias of it. This new control is used to
select the desired profile for VP8 encoder and query for supported profiles by
VP8 encoder/decoder.

Though we have originally a control V4L2_CID_MPEG_VIDEO_VPX_PROFILE and its name
contains 'VPX', it works only for VP8 because supported profiles usually differ
between VP8 and VP9. In addition, this control cannot be used for querying since
it is not a menu control but an integer control, which cannot return an
arbitrary set of supported profiles.

The new control V4L2_CID_MPEG_VIDEO_VP8_PROFILE is a menu control as with
controls for other codec profiles. (e.g. H264)

In addition, this patch also fixes the use of V4L2_CID_MPEG_VIDEO_VPX_PROFILE in
drivers of Qualcomm's venus and Samsung's s5p-mfc.
