The first thing that happens is that the native mediascanner code in opencore classifies files into container formats using extensions. It parses the container headers to see if it has video/audio and a few other details. Anything that doesn't fail here is available to the MediaPlayerService. Then you need to follow the MediaPlayerService::getPlayerType() where anything that's not vorbis or midi falls through to opencore, returning PV_PLAYER. This is what would happen in the case of your H.264 example (in an .mp4). At that point, createPlayer() is called to create an instance of the opencore player. -Matt --~--~---------~--~----~------------~-------~--~----~ unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting -~----------~----~----~----~------~----~------~--~---
