Subject: [PATCH 0729/1085] include: uapi: v4l2: Add additional pixel formats
|
||
|
|
for use with PiSP
|
||
|
|
|
||
|
|
Add the following formats:
|
||
|
|
|
||
|
|
- V4L2_PIX_FMT_RGB48/V4L2_PIX_FMT_BGR48
|
||
|
|
48-bit RGB where each colour sample is 16-bits.
|
||
|
|
|
||
|
|
- V4L2_PIX_FMT_PISP_COMP1_MONO/V4L2_PIX_FMT_PISP_COMP2_MONO
|
||
|
|
16-bit to 8-bit pisp compressed monochrome pixel format.
|
