Here's a V4L2 output module.
It is mostly indented to be used/and have been tested with the linux
v4l2loopback module (can be used to fake a v4l2 webcam or use a dv cam).
The usual way was to redirect the YUV vout into a fifo and then a v4l2 writer.
Unfortunately, some apps (skype, flash, ...) won't work with YUV or will require
a custom size. On the performance side, all current implementations were based
on device I/O only.
This module outputs in a negociated format, and tries to use mmap.
To make things even easier, applications profiles can be used to configure
With luck it should also work with regular v4l2 output devices (non mpeg stream).
