[media] Move DV-class control IDs from videodev2.h to v4l2-controls.h

2013-02-05T20:00:00Z

When the control IDs were split off from videodev2.h to v4l2-controls.h these new Digital Video controls were forgotten (the two patches may have crossed one another). Move these controls to their proper place in v4l2-controls.h. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-ctrl: Add helper function for the controls range update

2013-02-05T17:04:06Z

This patch adds a helper function that allows to modify range, i.e. minimum, maximum, step and default value of a v4l2 control, after the control has been created and initialized. This is helpful in situations when range of a control depends on user configurable parameters, e.g. camera sensor absolute exposure time depending on an output image resolution and frame rate. v4l2_ctrl_modify_range() function allows to modify range of an INTEGER, BOOL, MENU, INTEGER_MENU and BITMASK type controls.

[media] v4l: Define video buffer flags for timestamp types

2012-12-21T12:44:52Z

Define video buffer flags for different timestamp types. Everything up to now have used either realtime clock or monotonic clock, without a way to tell which clock the timestamp was taken from. Also document that the clock source of the timestamp in the timestamp field depends on buffer flags.

[media] v4l2: add new pixel formats supported on dm365

2012-12-19T15:02:10Z

add new macro V4L2_PIX_FMT_SGRBG10ALAW8 and associated formats to represent Bayer format frames compressed by A-LAW algorithm, add V4L2_PIX_FMT_UV8 to represent storage of CbCr data (UV interleaved) only.

[media] v4l: add buffer exporting via dmabuf

2012-11-25T19:20:47Z

This patch adds extension to V4L2 api. A new ioctl VIDIOC_EXPBUF is added. The ioctl is used to export an mmap buffer as a DMABUF file descriptor.

[media] v4l: Add DMABUF as a memory type

2012-11-25T19:10:36Z

Adds DMABUF memory type to v4l framework. Also adds the related file descriptor in v4l2_plane and v4l2_buffer.

[media] v4l2: Fix typo in struct v4l2_captureparm description

2012-10-28T20:39:39Z

Judging from what drivers do and from my experience temeperframe fraction is set in seconds - look e.g. here static int bttv_g_parm(struct file *file, void *f, struct v4l2_streamparm *parm) { struct bttv_fh *fh = f; struct bttv *btv = fh->btv; v4l2_video_std_frame_period(bttv_tvnorms[btv->tvnorm].v4l2_id, &parm->parm.capture.timeperframe); ... void v4l2_video_std_frame_period(int id, struct v4l2_fract *frameperiod) { if (id & V4L2_STD_525_60) { frameperiod->numerator = 1001; frameperiod->denominator = 30000; } else { frameperiod->numerator = 1; frameperiod->denominator = 25; } and also v4l2-ctl in userspace decodes this as seconds: if (doioctl(fd, VIDIOC_G_PARM, &parm, "VIDIOC_G_PARM") == 0) { const struct v4l2_fract &tf = parm.parm.capture.timeperframe; ... printf("\tFrames per second: %.3f (%d/%d)\n", (1.0 * tf.denominator) / tf.numerator, tf.denominator, tf.numerator); The typo was there from day 1 - added in 2002 in e028b61b ([PATCH] add v4l2 api)(*) (*) found in history tree git://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git Signed-off-by: Kirill Smelkov Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
