Select tracks by their string identifier.

This function can be used to pre-select a list of tracks before starting the player. It has only effect for the current media. It can also be used when the player is already started.

'str_ids' can contain more than one track id, delimited with ','. "" or any invalid track id will cause the player to unselect all tracks of that category. NULL will disable the preference for newer tracks without unselecting any current tracks.

Example:

(VIDEO_ES, "video/1,video/2") will select these 2 video tracks. If there is only one video track with the id "video/0", no tracks will be selected.
(SPU_ES, "${slave_url_md5sum}/spu/0) will select one spu added by an input slave with the corresponding url.

Note: The string identifier of a track can be found via vlc_es_id_GetStrId().
