deleting audio files does not delete them from the users media playlist

[MorrisJobke]

The playlist is stored in the browsers localStorage, so the delete hook has no way of updating the playlist there. Doing a rescan does not remove the files as well. We could check the playlist when loading the player and remove deleted items. @icewind1991 @jancborchardt what do you think? since we do not store the playlist on the server and cannot load or save them this might be the simplest soluton.

we should at least skip the files when the player reaches them but cannot find them

Yeah, your proposed solution sounds good. People should not have to manually rescan either way.

I have skipping of files working. Some minor issues before I create the pull request @jancborchardt Should I really delete missing files from the playlist?

@butonic hmm, maybe it’s better to not delete the missing files but just mark the playlist entry, e.g. with a yellow-ish background and maybe a tipsy note (»song could not be found«). That would not destroy people’s playlists, just skip these tracks, and allow to either reupload the source file to fix it or to delete the entry from the playlist.
