V4L/DVB (7198): V4L, include ioctl.h in videodev headers

2008-02-18T15:18:05+00:00

Fix compilation of user processes which includes videodev*.h but
not includes linux/ioctl.h:

v4l2ext_helper.c: In function 'process_ioctl':
v4l2ext_helper.c:183: warning: implicit declaration of function '_IOWR'
v4l2ext_helper.c:183: error: expected expression before 'struct'
v4l2ext_helper.c:183: error: case label does not reduce to an integer constant

V4L/DVB (6108): videodev2.h: add new pixel formats for the cx23415 OSD

2007-10-10T01:07:04+00:00

The Conexant cx23415 MPEG encoder/decoder supports some unusual pixelformats
for the On-Screen Display. Add new defines to videodev2.h for these formats.

V4L/DVB (5968): videodev2.h: remove superfluous FBUF GLOBAL_INV_ALPHA support

2007-08-20T15:18:01+00:00

There is no need for a global inverted alpha capability since all the
application has to do is to pass '255-alpha' as the global alpha value.

V4L/DVB (5867): videodev2.h: add missing for userspace

2007-07-20T20:35:52+00:00

When videodev2.h is included by an application, it needs to include
 for the timeval struct.

V4L/DVB (5736): Add V4L2_FBUF_CAP/FLAG_LOCAL/GLOBAL_INV_ALPHA

2007-06-08T11:21:15+00:00

Michael Schimek requested the addition of inverted alpha framebuffer
caps/flags to support such hardware.
'Normal' alpha uses this formula to mix the framebuffer and video:
output = fb pixel * fb alpha + video pixel * (1 - fb alpha)
and the 'inverted' alpha uses this formula:
output = fb pixel * (1 - fb alpha) + video pixel * fb alpha

V4L/DVB (5730): Remove unused V4L2_CAP_VIDEO_OUTPUT_POS

2007-06-08T11:21:14+00:00

V4L2_CAP_VIDEO_OUTPUT_POS was initially introduced for 2.6.22 but never
actually used: remove it before the final 2.6.22 is made.

V4L/DVB (5670): Adding new fields to v4l2_pix_format broke the ABI, reverted that change

2007-05-22T19:00:13+00:00

Reverted the change to struct v4l2_pix_format. I completely missed that
this struct was used by existing ioctls so that changing it broke the ABI.
I will have to think of another way of setting the top/left coordinates
but for now this change is reverted to preserve compatibility.

V4L/DVB (5306): Add support for VIDIOC_G_CHIP_IDENT

2007-04-27T18:43:27+00:00

VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be
used to detect which chips are on the board and based on that information
selected register dumps can be made, making it easy to debug complicated
media chips containing tens or hundreds of registers.
This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl.

V4L/DVB (5289): Add support for video output overlays.

2007-04-27T18:43:21+00:00

Add V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY support.
Also add support for local and global alpha overlays.
Add new field enums V4L2_FIELD_INTERLACED_TB and V4L2_FIELD_INTERLACED_BT.
These changes are needed to support the ivtv On Screen Display features.
