📄 Description

Changes

In the case that a track title isn't set for audio or subtitle tracks this change checks for a "handler_name" field to use as a title.

Explanation

Handbrake-produced mp4 files don't have a title set on audio or subtitle tracks, but looking at the handbrake code there's a check for mp4 file type that adds the title to the "handler_name" field: Audio Subtitle

Additionally, there's a note in the ffmpeg encoder referencing the use of "handler_name" for track description: movenc.c

As this seems to be a common/accepted use of the field, Jellyfin should read it if there is no track title set.
