Subject: vlc: with vlc 2.x, use vlcMedia for libvlc_MediaMetaChanged event
|
|
|
|
As reported by Wolfgang, the libVlc 2.x fix applied at
|
|
402cbee5e675 ("vlc: fix support for vlc 2.x") still have issues,
|
|
causing some troubles at least on audio CDs.
|
|
|
|
The root cause seems to be that, on vlc 2.x, the event
|
|
libvlc_MediaMetaChanged should be registered against the
|
|
vlcMedia instance, instead of vlcMediaPlayer instance.
|
|
|
|
Document that inside the code, as this is not obvious.
|
|
|
|
While the old way is still supported on vlc 3.x, I opted to
|
|
keep the code inside #ifs, as some day we'll drop support for
|
|
vlc 2.x, making the code simpler.
|
|
|
|
Also, since this event is registered aganst a vlcMedia object
|
|
and behaves different than when applied against a vlcMediaPlayer
|
|
object, I'm also using a different name there, in order to avoid
|
|
confusion.
