I'm currently trying to change my libpwc to be able to decompress the MJPEG
buffer and convert it in YUV420P or RGB24. So perhaps one day, we will have a
v4l2 library like in the alsa world. As i've a pretty small decoder, this can
be embeded in a lot of applications. But i don't known if more developper
will want to use the tiny library, so for the moment, it's just a small
pixel format convertion library.
