The quality is a bit less than I’m used to with Handbrake and this is video only (still need to find out how to add audio to gstreamer transcoding). However for the quality it’s at it is an impressive speed for something the size of a credit card that consumes 5V1A of power and costs only $35.

Here’s how I was able to get the Raspberry Pi to get this far.
