I tried examining the meta_type field in
libvlc_event_t->media_meta_changed but it was almost always
libvlc_meta_ArtworkURL and I never got a <em>libvlc_meta_Artist</em>,<em>
ibvlc_meta_Title</em>, or <em>libvlc_meta_Album</em>.<br>

<pre wrap="">I am using libvlc 1.1.0 to play an audio steam on Linux. I want to get the
title, album, and artist every time the track changes so I am hooking up a
callback function to the libvlc_MediaMetaChanged event. The problem is when
the stream starts playing the libvlc_MediaMetaChanged event is sent serveral
times before all the track meta data is valid. If I call
libvlc_media_get_meta(m,libvlc_meta_Artist), or
libvlc_media_get_meta(m,libvlc_meta_Album) too soon then I get a segment
fault. I thought about waiting for the libvlc_MediaPlayerPlaying event but
libvlc_MediaMetaChanged event is still sent several times before the album
and artist data is valid.
Is there a way to check if the artist and album data is valid before calling
libvlc_media_get_meta?

There is the meta_type field in the libvlc_event_t that describes what
meta (artist...) has changed. This should be what your are looking
for.
