[media] V4L: add two new ioctl()s for multi-size videobuffer management

2011-11-03T20:28:24+00:00

A possibility to preallocate and initialise buffers of different sizes
in V4L2 is required for an efficient implementation of a snapshot
mode. This patch adds two new ioctl()s: VIDIOC_CREATE_BUFS and
VIDIOC_PREPARE_BUF and defines respective data structures.

V4L/DVB (13571): v4l: Adding Digital Video Timings APIs

2009-12-16T02:18:03+00:00

This adds the above APIs to the v4l2 core. This is based on version v1.2
of the RFC titled "V4L - Support for video timings at the input/output interface"
Following new ioctls are added:-

        - VIDIOC_ENUM_DV_PRESETS
        - VIDIOC_S_DV_PRESET
        - VIDIOC_G_DV_PRESET
        - VIDIOC_QUERY_DV_PRESET
        - VIDIOC_S_DV_TIMINGS
        - VIDIOC_G_DV_TIMINGS

Please refer to the RFC for the details. This code was tested using vpfe
capture driver on TI's DM365. Following is the test configuration used :-

Blu-Ray HD DVD source -> TVP7002 -> DM365 (VPFE) ->DDR

A draft version of the TVP7002 driver (currently being reviewed in the mailing
list) was used that supports V4L2_DV_1080I60 & V4L2_DV_720P60 presets.

A loopback video capture application was used for testing these APIs. This calls
following IOCTLS :-

 -  verify the new v4l2_input capabilities flag added
 -  Enumerate available presets using VIDIOC_ENUM_DV_PRESETS
 -  Set one of the supported preset using VIDIOC_S_DV_PRESET
 -  Get current preset using VIDIOC_G_DV_PRESET
 -  Detect current preset using VIDIOC_QUERY_DV_PRESET
 -  Using stub functions in tvp7002, verify VIDIOC_S_DV_TIMINGS
    and VIDIOC_G_DV_TIMINGS ioctls are received at the sub device.
 -  Tested on 64bit platform by Hans Verkuil

V4L/DVB (10813): v4l2: New function v4l2_video_std_frame_period

2009-03-30T15:43:05+00:00

Some code was calling v4l2_video_std_construct() when all it cared about
was the frame period.  So make a function that just returns that and have
v4l2_video_std_construct() use it.

At this point there are no users of v4l2_video_std_construct() left outside
of v4l2-ioctl, so it could be un-exported and made static.

Change v4l2_video_std_construct() so that it doesn't zero out the struct
v4l2_standard passed in.  It's already been zeroed out in the common ioctl
code.

V4L/DVB (10141): v4l2: debugging API changed to match against driver name instead of ID.

2009-01-02T19:11:52+00:00

Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.

Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.

Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

V4L/DVB (10139): v4l: rename v4l_compat_ioctl32 to v4l2_compat_ioctl32

2009-01-02T19:11:39+00:00

This rename prevents conflicts with the older compat_ioctl32 module.
