TechRec
A Python3 web application that assist radio speakers in recording their shows. Meant to be simple to install and to maintain.
It basically takes a directory with the continuous recording and create new files "cutting/pasting" with ffmpeg.
Features
- little system dependencies: python3 and ffmpeg
- The interface is extremely simple to use
- Supports nested recording (ie: to record an interview inside of a whole show)
- There is no user system: any user opening the website will see the complete status of the applications. There is, also, nothing stored in cookie or similar mechanisms. This means that recording a session does not require a browser to remain open, or any kind of persistence client-side: server-side does it all. It also means that authorization must be done on another layer (for example, your webserver could add a Basic Auth)
How does it work
We suppose that you have a continous recording of your radio broadcasting. What techrec does is taking files from this directory and "cutting/pasting" parts of them. This can boil down to something like
ffmpeg -i concat:2014-20-01-00-00.mp3|2014-20-01-00-01.mp3 -acodec copy -ss 160 -t 1840 foo.mp3
This continous recording needs to be configured so that:
- It can be split in multiple directories, but the granularity of this must be below one directory per day.
- The filename must be fully informative, without looking at the parent directories.
How to run
pip install .
env TECHREC_CONFIG=yourconfig.toml techrec serve
Implementation details
It is based on fastapi, a really nice framework. Simple APIs are offered through it, and the static site uses them through JS.
Jobs are not dispatched using stuff like celery, but just using
BackgroundTasks,
in order to keep the installation as simple as possible.
The encoding part is delegated to ffmpeg, but the code is really modular so
changing this is a breeze. To be quicker and avoid the quality issues related
to reencoding, the codec "copy" is used: this means that input and output must
have the same format.
testing
gitlab-runner exec docker test
(or, pytest-3, assuming you have a properly configured system)
