From 4365e08f272ba098698196234dbd38ac3dd5a606 Mon Sep 17 00:00:00 2001 From: Dave Stevenson 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 V4L2: Correct JPEG Q-factor range Should be 1-100, not 0-100 Signed-off-by: Dave Stevenson 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 V4L2: Fix ISO controls. Driver was passing the index to the GPU, and not the desired ISO value. Signed-off-by: Dave Stevenson V4L2: Add flicker avoidance controls Add support for V4L2_CID_POWER_LINE_FREQUENCY to set flicker avoidance frequencies. Signed-off-by: Dave Stevenson 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 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 V4L2: Fix information advertised through g_vidfmt Width and height were being stored based on incorrect values. Signed-off-by: Dave Stevenson 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 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 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. Signed-off-by: Dave Stevenson V4L2: Enable MJPEG encoding Requires GPU firmware update to support MJPEG encoder. Signed-off-by: Dave Stevenson V4L2: Correct flag settings for compressed formats Set flags field correctly on enum_fmt_vid_cap for compressed image formats. Signed-off-by: Dave Stevenson 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. Signed-off-by: Dave Stevenson V4L2: Correct BGR24 to RGB24 in format table Signed-off-by: Dave Stevenson V4L2: Add additional pixel formats. Correct colourspace Adds the other flavours of YUYV, and NV12. Corrects the overlay advertised colourspace. Signed-off-by: Dave Stevenson V4L2: Drop logging msg from info to debug Signed-off-by: Dave Stevenson V4L2: Initial pass at scene modes. Only supports exposure mode and metering modes. Signed-off-by: Dave Stevenson 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. Signed-off-by: Dave Stevenson 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. Signed-off-by: Dave Stevenson 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. Signed-off-by: Dave Stevenson 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. Signed-off-by: Dave Stevenson V4L2: Add support for V4L2_PIX_FMT_BGR32 Signed-off-by: Dave Stevenson 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. Signed-off-by: Dave Stevenson 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. Signed-off-by: Dave Stevenson V4L2: Fix incorrect pool sizing Signed-off-by: Dave Stevenson 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). Signed-off-by: Dave Stevenson V4L2: Add support for more image formats Adds YVU420 (YV12), YVU420SP (NV21), and BGR888. Signed-off-by: Dave Stevenson 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.
