问题 I need to play let's say 10 songs (1-10) serially. After one is played and finished, the next one starts, etc. What I have in mind is: For (int i=0; i<10; i++) { mp = new MediaPlayer(); mp.setDataSource(/* something given i */); mp.prepare(); mp.start(); } But won't that cause just one song to be played only?

I read through some examples and the documentation and this is what I have tried, (note the line myPlayer.currentTime(30);): Script: var myPlayer = amp('vid1', { /* Options */ "nativeControlsForTouch": false, autoplay: false, controls: true,

问题 I am trying to play some audio in background using two MediaPlayers inside a Service.

I found that is because the AVMutableComposition I use just put the original music format in to the video I generated. So is there any way I can lower the bitrate of the music in MPMediaItem, or change the format it is encoded? This is a code snippet of the code I use to add music to video. AVMutableComposition* mixComposition =

问题 Just a very short question: How can I find out if the MPMoviePlayerController instance is buffering data (in this case audio data from a web stream)? Thanks for any kind of help and have a nice day! 回答1: You need to register an object to be notified by the MPMoviePlayerLoadStateDidChangeNotification and then access the loadState of the movie player. See the notifications section of the MPMoviePlayerController reference. 来源： https://stackoverflow.com/questions/9550813/mpmovieplayercontroller
