libvlc_media_tracks_get returns 0 on mac os x

[Zajo]

Hello, on Mac OS X I'm using libvlc to play videos, and I'm calling libvlc_media_tracks_get but it returns 0 after the media was successfully parsed. This same code works correctly on Windows, with the same media file. Any idea what I might be doing wrong? What is the best way to diagnose the issue? Thanks!

I have the same question on Windows. after parsed media, libvlc_media_tracks_get returns 0 for mpeg2 file, but returns >0 for mkv file.
after played media and delayed for about 1-2 seconds, it always returns > 0.

Thanks!

Some formats spawn tracks asynchronously. Sorry but deal with it.
