V_Videocompile

Master repo to compile ffmpeg for veda & veda subsidiaries

Intro

There wasn't a good, universal *nix solution to compiling ffmpeg on various node, ingest, and worker machines. It's simple and should work for most local and AWS instances, assuming the running of a *nix machine.

This won't compile a full-flavored version of ffmpeg, this is just for what we use (and might use later) at edX. You'll get mp3, mp4, and theora, as well as the basic HLS encoder.

If you're interested in ffmpeg, and want something that's a little more functional for general and workaday use: https://trac.ffmpeg.org/wiki/CompilationGuide

NOTE: 'Impolite' full compilation isn't currently working with terraform - though the script will run if run manually.

So We've backed off into a 'polite' build, using a (known, tested) static build for EC2 instances and a brew-based install for Darwin machines

This will check for an extant ffmpeg install, and install if the global command ffmpeg returns something that doesn't look like ffmpeg.

Use (for compile) <--currently in bin

from v_videocompile import VideoCompile

F = VideoCompile(
    compile_dir=${optional directory}
    )
F.drun()

Use (for impolite compile)

from v_videocompile import VideoCompile

F = VideoCompile(
    compile_dir=${optional directory}
    )
F.run()

This software uses code of FFmpeg licensed under the LGPLv2.1 and its source can be downloaded here: http://ffmpeg.org/releases/ffmpeg-3.1.1.tar.bz2

NOTE: Does not compile on Windows machines (poss. a later release)
