PyTranscode is a set of scripts to make handling ffmpeg easier in python, it enables video information extraction, transcoding, presets, splash image extraction (multiple) and state reporting (percentage complete)

1. What is this?
A while back I wrote a proof-of-concept webapp that basically replicated what Brightcove and other online video management tools did, and at its heart was a tool to control FFMPEG - one of the best command-line transcoders out there.
Now the webapp never took off (it was never launched, pending a rewrite), but I had started on rewriting the engine that would control the transcoder software.
I’ve since moved my limited attention span to other, shineir things, but thought I would release this piece of rather nifty and handy code to the public to help others who want to do something with video and don;t want to fork out a fortune.
2. Hopeful Roadmap
PyTranscode is hopefully going to be part of something bigger - the vision is to produce a set of django applications which can do the following:
A storage engine for local or cloud-based storage
A queue manager for scaling, this again would have vairous back-ends for local queue management or something like Amazon Queue Service
A transcode server that can be run on multpile machines and be managed via an API OR be run in a mode to interact with the queue service
An API wrapper to control the transcode-server for common tasks
3. How to use the scripts
There are five files with PyTranscode, these have the following basic functionsality:
- ffmpeg.py: Can be used to build a command line to run ffmpeg for various
settings with input/output
- presets.py: Some presets to use with ffmpeg if you can;t be bothered to
write out the long dictionaries some transcodes require
- runner.py: Runner basically allows you to run ffmpeg in a managed way and
trap the output as well as the percentage complete
- splash.py: This will let you pull thumbnails at equal intervals from the
inpout file and return the filenames
- video_info: Need to know everything about a video file? This basically parses
the -i output from ffmpeg to get all the details and present them as a class
Depending on what you need, the documentation on how to use each one is in the header of the file.
If you want to see a test run, there’s the file test.py which should show an easy way to get started with these classes.
