Recording video for streaming and storage is hard. 

Open hardware is fun.

Lets create some open hardware to record video!

The timvideos project is an effort to create an easy to use, modern video recording workflow for conferences like linux.conf.au. Central to this effort is HDM2USB, a FPGA based HDMI capture board.

The FPGA system captures video, does compression, USB streaming, and more, and it’s built on open hardware to boot. Come learn about the challenges of designing an open video capture system, and how to use open source to help you along the way.
