FB2V4L

This little program connects a virtual framebuffer device to a virtual v4l device. This allows you to run framebuffer-enabled software (such as X with the fbdev driver) and have the output turned into a video stream which can be captured (for example with OpenBroadcast).

Requires:

• Virtual Framebuffer Module - https://github.com/Freescale/linux-module-virtfb
• V4L Loopback Module - https://github.com/umlaeute/v4l2loopback

Usage:

1. Load the above modules
2. Start a session, for example:
fb2v4l -f /dev/fb1 -v /dev/video3

You can now wrote to /dev/fb1 and the results will be shown on /dev/video3.

You can specify the dimensions using:

fb2v4l -w 640 -h 480 -f /dev/fb1 -v /dev/video3

The default size is 800x600 and it always uses 32-bit RGBA.
