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.
