down-frab-videos

Download videos and lecture attachments from events managed with the frab system or with the pretalx (like the Chaos communication congress, MRMCD, Camp, ...)

By default the most recent, known chaos event is considered and high-quality webm files are downloaded. This can, however, be changed using the --event and --format flags respectively. A list of configured events and available formats for a given event can be printed (using flags --list-events and --list-formats). For a list of all flags the script understands, try

down-frab-videos --help

When downloading a talk the script will not only download the recording, but also some information from the frab Fahrplan as well. This includes:

• The attached files
• The abstract and summary for the talk
• The list of links and references

In order to download talks, you just need to provide the script with a list of talk ids. You can find the talkid in the url of your webbrowser. For example the frab page with url ending in events/8414.html has the talkid 8414 and the pretalx page ending in talk/VHLTSN/ corresponds to talkid VHLTSN.

You can either list the talkids line-by-line in a file and hand that file over to the script via the argument --input-file. For example the file

6258
# some crazy comment
6450

downloads the talks with IDs 6258 and 6450. For downloading only a small number of talks with the script the command line syntax

down-frab-videos 6258 6450

is usually more convenient.

Some of the options configured via the command line can be set more permanently via a configuration file as well. To get started with this you should dump the defaults using

down-frab-videos --dump-config

This will write a stub config to ~/.config/down-frab-videos/config.yaml.
