Feature Request: Add support for Bayer image format

Description

A lot of new cheap webcams output their images in Bayer format. According to the driver writers it is not the job of the driver to provide a conversion routine to something like RGB24, this has to be done in the userspace application. I've found a bit of code that converts Bayer to RGB24, I hope this will make it easier to include support for this image format in Motion, as I'm not a coder I don't really understand what it does, hopefully one of you guys will be able to fathom it out. The file is attached.

• bayer.c: Bayer to RGB

[Update: Bayer seems to be supported natively under V4L2]

As motion works with YUV420P Palette is better to do a conversion from Bayer ( gbrg ? ) to YUV420P intead of Bayer <-> RGB24 <-> YUV420P . There's some work that seems is working around this issue.

• I would not mind adding it if someone writes it. Not currently being developed by anyone and not on the high priority list for the currently active developers. -- KennethLavrsen - 17 Mar 2005

Comments

Supporting bayer would be relativly easy if it was just treated as if it was an black and white Y plane. If that is done the detection would work just fine... Only when the real image would have to be outputted would it have to be converted and only if the output doesn't understand bayer itself. (e.g. the vloopback would need no conversion, ffmpeg might not need it and jpeg probably will need it)
