Code description

1, the vlc-android version is 2.2.0-pre1 Weatherwax

2, copy vlc-android official website example below ORG.VIDEOLAN.LIBVLC all classes, as well as Vlcinstance, Preferences. Only the voice does not have the picture on vlcinstance this question, has less some configuration, the reference vlcinstance.updatelibvlcsettings.

3, PLAYMRL do not use the URI to turn, otherwise can not open

4, the code provided has been compiled so, also modify the source open eventhandler.mediaplayerbuffering (also modified LIBVLCJNI.C), but there is no buffer progress value, still need to explore further.

5, the actual discovery if only in surfacechanged Attachsurface,setsurfacesize callback does not trigger, you need to set in surfacecreated.

6, this article does not discuss the handler non-static may cause the memory leaks the question, everybody writes the time oneself notice:)

Article

1, vlc-android call with libvlcjni.so to achieve streaming media playback

2, [Github]vlc-android-macbuild

3, VLC Android compilation and, recording video and other functions

4, Vlc-android source code compilation process record

5, Vlc-android get the response of mediaplayerencounterederror,mediaplayerbuffering and other events

6, Vlc-for-android Source analysis

End

Article 2 of the GitHub project is for VLC encapsulation, also quite good, worth reference. Vlc-android's example is more complex, and the API may be old, and when you look at the article, take note of the version issue.
