Subject: [PATCH] bcm2835: add v4l2 camera device
|
|
|
|
- Supports raw YUV capture, preview, JPEG and H264.
|
|
- Uses videobuf2 for data transfer, using dma_buf.
|
|
- Uses 3.6.10 timestamping
|
|
- Camera power based on use
|
|
- Uses immutable input mode on video encoder

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.

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.

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: 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).

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.

BCM2835-V4L2: Fix compliance test failures
|
|
|
|
VIDIOC_TRY_FMT and VIDIOC_S_FMT tests were faling due
|
|
to reporting V4L2_COLORSPACE_JPEG when the colour
|
|
format wasn't V4L2_PIX_FMT_JPEG.

|
Now reports V4L2_COLORSPACE_SMPTE170M for YUV formats.

bcm2835 camera planar/packed stride length
|
|
|
|
Added a field to the mmal_fmt struct used to compute the bytes per line
|
|
when using a particular format. This results in the correct stride being
|
|
calculated even when the format is planar.

|
|
|
|
it is possible that scene is not found because of an invalue ctrl->val
|
|
and is therefore NULL and hence causing a null pointer dereference.

+==============
|
|
+
|
|
+You need a version 1.0 or later of v4l2-ctl, available from:
|
|
+ git://git.linuxtv.org/v4l-utils.git
|
|
+
|
|
+$ sudo modprobe bcm2835-v4l2

|
|
+Turn on the overlay:
|

+
|
|
+$ v4l2-ctl --overlay=1
|
|
+
|
|
+Turn off the overlay:
|
|
+
|
|
+$ v4l2-ctl --overlay=0
|
|
+
|
|
+Set the capture format for video:
|
|
+
|
|
+$ v4l2-ctl --set-fmt-video=width=1920,height=1088,pixelformat=4
|
|
+
|
|
+(Note: 1088 not 1080).
|
|
+
|
|
+Capture:
|
|
+
|
|
+$ v4l2-ctl --stream-mmap=3 --stream-count=100 --stream-to=somefile.h264
|
|
+
|
|
+Stills capture:
|
