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.

V4L/DVB (5272): Add V4L2_CAP_VIDEO_OUTPUT_POS capability

2007-04-27T18:43:19+00:00

Add V4L2_CAP_VIDEO_OUTPUT_POS capability and x, y position coordinates
to struct v4l2_pix_format.
This is needed to support positioning the MPEG/YUV output of the cx23415.

V4L/DVB (5268): Add support for three new MPEG controls.

2007-04-27T18:43:18+00:00

Added V4L2_CID_MPEG_AUDIO_MUTE, V4L2_CID_MPEG_VIDEO_MUTE and
V4L2_CID_MPEG_CX2341X_STREAM_INSERT_NAV_PACKETS controls together with
their implementation in the cx2341x module.

V4L/DVB (5305): Mark VIDIOC_DBG_S/G_REGISTER as experimental

2007-03-01T15:09:46+00:00

Move VIDIOC_DBG_S/G_REGISTER from the internal ioctl list to the
public ioctls, but mark it as experimental for now.

The VIDIOC_G_ENC_INDEX ioctl can obtain the MPEG index from an MPEG
encoder.
