Subject: Fix: Subsonic Scrobble: Split the internal id for Podcast Episode (#2203)
X-Git-Url: https://git.kitaultman.com/?a=commitdiff_plain;h=7c6f40cd947a7ffc6f21b1cd9d55d85bb6c1f699;p=music-assistant-server.git

Fix: Subsonic Scrobble: Split the internal id for Podcast Episode (#2203)

The Subsonic API only recently added an optional endpoint for retrieving
the metadata for an individual podcast episode but most servers do not
yet implement it. The only way to get an individual episode is through
its channel. This means that we have to include both IDs in the MA
provider ID for an episode.

This causes a problem when scrobbling because we are presented with an
ID that is not actually valid for the subsonic server. In the case where
the string EP_CHAN_SEP exists in the provider id, split it and only call
scrobble on the episode portion.
