The Raspberry Pi is not bad at hardware H264 encoding. It processed a 5.81GB 720P 60fps Mpeg Transport Stream that was an 1hr, 2min, 27seconds long and converted to H264 1280 x 720 60fps in 1hr, 38min, 57seconds with a resulting file size of 293MB.

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.

So without further ado here’s a script that takes recording from TVHeadend and transcodes it to an h264/AAC mp4 file using the “Normal” preset in Handbrake(CLI).
