media: v4l2-ctrl: add MPEG-2 profile and level controls

2019-05-29T10:19:12+00:00

Add MPEG-2 CID definitions for profiles and levels defined in ITU-T Rec.
H.262.

media: coda/venus/s5p_mfc: fix control typo

2019-05-28T16:07:22+00:00

These two slice modes used by the V4L2_CID_MPEG_VIDEO_MULTI_SLICE_MODE
control had a silly typo:

V4L2_MPEG_VIDEO_MULTI_SICE_MODE_MAX_MB
V4L2_MPEG_VIDEO_MULTI_SICE_MODE_MAX_BYTES

SICE should be SLICE.

Rename these enum values, keeping the old ones (under #ifndef __KERNEL__)
for backwards compatibility reasons.

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

2018-11-02T10:36:32+00:00

As warned by "make headers_check", the definition for the linux-specific
integer types is missing:

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

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.
