I’m also fairly certain that this line “omxmpeg2videodec” requires the MPEG2 codec installed which I purchased from Raspberry Pi from here for under $5: Gst-launch-1.0 filesrc location=/home/pi/ ! tsdemux ! mpegvideoparse ! omxmpeg2videodec ! videoconvert ! omxh264enc ! h264parse ! avimux ! filesink location=/home/pi/Gotham.m4v I used this code in terminal to transcode input file to output file Gotham.m4v I changed the video RAM split on the RPi to give it 128MB (I run the RPi headless from SSH so I had video RAM set at 16MB and received errors that the encoder wouldn’t start). I installed an OpenMax enabled version of gstreamer from here: Here’s how I was able to get the Raspberry Pi to get this far. 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. 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). 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 Raspberry Pi is not bad at hardware H264 encoding. ***Scroll to bottom of article to see updated code with audio & video trancoding.***
