svtplay-dl: Issues with detecting and avoiding duplicates

svtplay-dl versions:

3.2

Operating system and Python version:

Windows 10 (2004) Python 3.8 (included in release) Python 3.9.2 (global install)

What is the issue:

There doesn’t seem to exist a consistent way avoiding to download duplicates, especially when the episode IDs might change.

When id’s has changed

svtplay-dl.exe --subtitle --all-episodes https://www.svtplay.se/exit when IDs have not changed will skip the already downloaded episodes unless -force is specified

When id’s have changed it will download the episode again.

Downloading only episodes after date

svtplay-dl.exe --subtitle --after-date 2021-03-06 https://www.svtplay.se/exit renders this error:

ERROR: No videos found. This mode is not supported anymore. Need the url with the video.

Downloading only latest 5 episodes

svtplay-dl.exe --subtitle --all-last 5 https://www.svtplay.se/exit render this error:

ERROR: No videos found. This mode is not supported anymore. Need the url with the video.

(Bad workaround) Downloading only missing episodes with some scripting

1. Find the available episodes with svtplay-dl.exe --subtitle --all-episodes --get-only-episode-url https://www.svtplay.se/exit
2. Exclude the local episodes by matching season and episode

The issue with this approach is that the output is 1) hard to parse and 2) is doesn’t return the s0Xe0X for you so you can’t easily match this with your local episodes. Is there an easier way parse the episode information from svtplay-dl?

(Better workaround) Download only missing via exclusion with powershell:

1. Get a list of all local episodes and create a list of each s0Xe0X pattern
2. Use the --exclude option to exclude episodes matching this pattern

svtplay-dl.exe --subtitle --all-episodes --exclude $((Get-Item * -Filter *.mp4 | ForEach-Object { $_.BaseName -replace '.*(s\d+e\d+).*','$1'}) -join ',') https://www.svtplay.se/exit

It works but it’s not especially fast.

(Future solution?) Custom output format

Can the output format be customized in any way? I’m thinking that specifying a custom output file format could help detecting duplicates when downloading multiple episodes.

Something like:

svtplay-dl.exe --all-episodes URL --episode-name-format '%series%.%season%%episode%%title%'

then if the file names match a existing local one it’ll be skipped, unless -force is supplied.
