Here is a new version taking into account Roland remarks:

https://code.videolan.org/tguillem/vlc/commits/multiple-es/4

And a diff between the new branch and the old one: https://code.videolan.org/snippets/983

What changed

 - Rename vlc_spu_channel_order to vlc_vout_order:
The order can be attributed to SPU and VIDEO ESes. For a VIDEO_ES, the primary ES is the ES using the main vout (most likely embebed inside the UI (when supported)).

 - Merge input vout event with the spu one

 - Add vlc_player_AddEsId():
An helper that will use vlc_player_SelectEsIdList(): way more convenient to just add one track.
 
 - vlc_player_SelectEsIdList() and vlc_player_AddEsId return the number of selected tracks.

 - vlc_player_SelectEsIdList() now handle the limit of tracks per category. It won't try to select more than 2  subtitles tracks for example.

Regards,
