Mutate XMLTV guide data to fix errors.
When using Channels with the XMLTV data for Australia, I found there were a bunch of things that were just not quite right.
For instance, episodes on the ABC that did not have the <previously-shown> tag did not have the <premiere> tag; this caused Channels to not mark these episodes as "New".
This is problematic because these episodes are often repeated several times during the week, resulting in no way to filter these out.
This is an attempt to fix that. It runs a Quart server that acts as a proxy, downloading the referenced file, mutating it, and then returning the mutated version.
The following mutations are applied to each program:
- If the program does not contain
<previously-shown>, then add the<premiere>tag (if it is not present). This excludes SBS programmes, which do not contain the<previously-shown>element. - If the program contains both
<previously-shown>and<premiere>tags, remove the latter.
You can run the server locally, to debug issues or add extra mutations:
$ poetry install
$ poetry shell
$ python app.py
It listens on interface 0.0.0.0 to enable you to point your Channels (or other DVR) at this server.
You'll probably want to run it in a better way: I run Channels DVR using a docker-compose.yml file, which can be extended to run this server too:
version: "3.5"

lan:
external: true

Your setup may vary. I use an external network, for instance.
