From 4365e08f272ba098698196234dbd38ac3dd5a606 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dsteve@broadcom.com>
Date: Mon, 9 Dec 2013 10:58:01 +0000
Subject: [PATCH 31/54] V4L2: Fixes from 6by9
V4L2: Fix EV values. Add manual shutter speed control
V4L2 EV values should be in units of 1/1000. Corrected.
Add support for V4L2_CID_EXPOSURE_ABSOLUTE which should
give manual shutter control. Requires manual exposure mode
to be selected first.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Correct JPEG Q-factor range
Should be 1-100, not 0-100
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Fix issue of driver jamming if STREAMON failed.
Fix issue where the driver was left in a partially enabled
state if STREAMON failed, and would then reject many IOCTLs
as it thought it was streaming.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Fix ISO controls.
Driver was passing the index to the GPU, and not the desired
ISO value.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Add flicker avoidance controls
Add support for V4L2_CID_POWER_LINE_FREQUENCY to set flicker
avoidance frequencies.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Add support for frame rate control.
Add support for frame rate (or time per frame as V4L2
inverts it) control via s_parm.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Improve G_FBUF handling so we pass conformance
Return some sane numbers for get framebuffer so that
we pass conformance.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Fix information advertised through g_vidfmt
Width and height were being stored based on incorrect
values.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Add support for inline H264 headers
Add support for V4L2_CID_MPEG_VIDEO_REPEAT_SEQ_HEADER
to control H264 inline headers.
Requires firmware fix to work correctly, otherwise format
has to be set to H264 before this parameter is set.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Fix JPEG timestamp issue
JPEG images were coming through from the GPU with timestamp
of 0. Detect this and give current system time instead
of some invalid value.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Fix issue when switching down JPEG resolution.
JPEG buffer size calculation is based on input resolution.
Input resolution was being configured after output port
format. Caused failures if switching from one JPEG resolution
to a smaller one.

V4L2: Enable MJPEG encoding
Requires GPU firmware update to support MJPEG encoder.

V4L2: Correct flag settings for compressed formats
Set flags field correctly on enum_fmt_vid_cap for compressed
image formats.

V4L2: H264 profile & level ctrls, FPS control and auto exp pri
Several control handling updates.
H264 profile and level controls.
Timeperframe/FPS reworked to add V4L2_CID_EXPOSURE_AUTO_PRIORITY to
select whether AE is allowed to override the framerate specified.

V4L2: Correct BGR24 to RGB24 in format table
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Add additional pixel formats. Correct colourspace
Adds the other flavours of YUYV, and NV12.
Corrects the overlay advertised colourspace.

V4L2: Initial pass at scene modes.
Only supports exposure mode and metering modes.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Add manual white balance control.
Adds support for V4L2_CID_RED_BALANCE and
V4L2_CID_BLUE_BALANCE. Only has an effect if
V4L2_CID_AUTO_N_PRESET_WHITE_BALANCE has
V4L2_WHITE_BALANCE_MANUAL selected.

config: Enable V4L / MMAL driver
V4L2: Increase the MMAL timeout to 3sec
MJPEG codec flush is now taking longer and results
in a kernel panic if the driver has stopped waiting for
the result when it finally completes.
Increase the timeout value from 1 to 3secs.

V4L2: Add support for setting H264_I_PERIOD
Adds support for the parameter V4L2_CID_MPEG_VIDEO_H264_I_PERIOD
to set the frequency with which I frames are produced.

V4L2: Enable GPU function for removing padding from images.
GPU can now support arbitrary strides, although may require
additional processing to achieve it. Enable this feature
so that the images delivered are the size requested.

V4L2: Set the colourspace to avoid odd YUV-RGB conversions
Removes the amiguity from the conversion routines and stops
them dropping back to the SD vs HD choice of coeffs.

V4L2: Make video/still threshold a run-time param
Move the define for at what resolution the driver
switches from a video mode capture to a stills mode
capture to module parameters.

V4L2: Fix incorrect pool sizing

V4L2: Add option to disable enum_framesizes.
Gstreamer's handling of a driver that advertises
V4L2_FRMSIZE_TYPE_STEPWISE to define the supported
resolutions is broken. See bug
https://bugzilla.gnome.org/show_bug.cgi?id=726521
Optional parameter of gst_v4l2src_is_broken added.
If non-zero, the driver claims not to support that
ioctl, and gstreamer should be happy again (it
guesses a set of defaults for itself).

V4L2: Add support for more image formats
Adds YVU420 (YV12), YVU420SP (NV21), and BGR888.
Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
V4L2: Extend range for V4L2_CID_MPEG_VIDEO_H264_I_PERIOD
Request to extend the range from the fairly arbitrary
1000 frames (33 seconds at 30fps). Extend out to the
max range supported (int32 value).
Also allow 0, which is handled by the codec as only
send an I-frame on the first frame and never again.
There may be an exception if it detects a significant
scene change, but there's no easy way around that.
