Subject: [PATCH 00/05] video: Extended vivi pixel format support
Date: Tue, 14 Oct 2008 21:46:51 +0900 [thread overview]
Message-ID: <20081014124651.5194.93168.sendpatchset@rx1.opensource.se> (raw)
Extended vivi pixel format support
[PATCH 01/05] video: Precalculate vivi yuv values
[PATCH 02/05] video: Teach vivi about multiple pixel formats
[PATCH 03/05] video: Add uyvy pixel format support to vivi
[PATCH 04/05] video: Add support for rgb565 pixel formats to vivi
[PATCH 05/05] video: Add support for rgb555 pixel formats to vivi
These patches improve the RGB->YUV color space conversion code
in vivi.c and also add support for the following pixel formats:
V4L2_PIX_FMT_UYVY
V4L2_PIX_FMT_RGB565 /* gggbbbbb rrrrrggg */
V4L2_PIX_FMT_RGB565X /* rrrrrggg gggbbbbb */
V4L2_PIX_FMT_RGB555 /* gggbbbbb arrrrrgg */
V4L2_PIX_FMT_RGB555X /* arrrrrgg gggbbbbb */
With these patches the vivi driver can be used as a reference for
testing the byte order of 16-bit pixel formats. This allows testing
of user space software without actual capture hardware. It is also
useful for people who are developing new drivers and have doubts
which 16-bit RGB interpretation is the valid one (RGB vs BGR).
The color space conversion code is updated to use precalculated YUV
values instead of doing RGB->YUV calculation for every two pixels.
