[vlc-devel] [PATCH v2 5/5] libvlc: media: set WITH_ASSOCIATED_MEDIA option to preparser

When a LibVLC client associates multiple inputs to a media through the
input slave mechanism, it should expect that all associated media get
preparsed so that listing tracks and elementary stream ids give
a comprehensive result.

To achieve this, always set the WITH_ASSOCIATED_MEDIA when requesting
a preparsing from the LibVLC API.
