Should prefer 'main' track over alternate if same quality #69

Closed Jean-Daniel closed 3 months ago

Jean-Daniel commented 4 months ago

I'm trying to download a file with 2 audio tracks with the same quality, but one is used for audio description. dash-mpd-cli is choosing the second one with role alternate, instead of favoring the track with role main.

When choosing the track, it should favor track with main role instead.

Thanks for the suggestion. This should be implemented (with a commandline option allowing you to modify the preference ordering for role specifications) in the latest release.
