When you call addSourceBuffer on a MediaSource, you need to pass in a string that is the MIME type for the codec. If this isn't correct, the video won't play. (You can also pass this to the MediaSource's isTypeSupported function, though there seems to be a gap between what it thinks it can play and what it will play.)

The string looks like this:

video/mp4; codecs="avc1.42E01E, mp4a.40.2"

The values required in that string can be obtained by running the mp4file tool from mp4v2 on a video file, like so:

 mp4file --dump movie.mp4

Open Computing Language (OpenCL) is a language and framework for writing computationally intensive kernels that run accross heterogenious platforms, including GPUs, CPUs, and perhaps other more esoteric devices.

Intel provides an OpenCL implementation for Intel CPUs, but there's not a lot of instructions on how to get it set up. Here's what I did.

Installing Intel CPU OpenCL on Ubuntu (12.04)

Download the Intel® SDK for OpenCL* Applications XE 2013 from the Intel website, here http://software.intel.com/en-us/vcsource/tools/opencl-sdk-xe. The download is a tarball -- the one I got is called intel_sdk_for_ocl_applications_2013_xe_sdk_3.0.67279_x64.tgz
Unpack the tarball and cd into the new directory

Busybox "Embedded Linux from Scratch" Distribution for the Beaglebone

Prepare your Build Sandbox

$ mkdir -p beaglelfs/{sources,rootfs_install,boot_mnt,rootfs_mnt}

Acquire an ARM Toolchain

Download the latest i686 Binary TAR of the ARM GNU/Linux (glibc-based) Lite Toolchain:

	#!/usr/bin/env bash

	# set -x

	if [[ $EUID -ne 0 ]]; then
	echo "You must be root to run this script"
	exit 1
	fi

	# Returns all available interfaces, except "lo" and "veth*".
