应用层调用播放器的方法例如点击列表播放:
1.首先取得当前的device 然后进行播放
LTDevice *device = [AppUtils getDeviceMonitor].getDeviceManager.getCurDevice;
if (device.player) {
if (self.playlist && startIndex < self.playlist.songs.count) {
[device.player playWithIndex:startIndex playlist:self.playlist];
}
}
播放歌曲的方法:
LTMediaPlayer中调用这个API播放;
1.- (void)playWithIndex:(NSInteger)index playlist:(LTPlaylist *)playlist
Kxmovie中调用下面这个API播放;
2.- (void)play:(LTSong *)song position:(CGFloat)position
这个API 根本上是根据Url ,所以内部要获取song的Url
- (void)getCacheUrlWithSong:(LTSong *)song position:(CGFloat)position listener:(getCacheListener)listener;
本地的songUrl 是localUrl;
1.方法代码如下 主要根据不同情况做各种处理,但这些情况没有做具体说明;
- (void)playWithIndex:(NSInteger)index playlist:(LTPlaylist *)playlist {
if ([self ipIsValid] && playlist) {
//如果有手机正在播放，则需要提交到服务器
if (type == LOCAL && _playInfo.status == PLAYING && [_playInfo.progress longTimeValue] >= 5) {
[self subjectPlayInfo];
}
[self setPlaylist:[playlist copyObject]];
if (_playInfo.playlist && index >= 0 && index < [_playInfo.playlist.songs count]) {
_playInfo.index = index;
LTSong *song = [_playInfo.playlist.songs objectAtIndex:index];
if (song.from != FROM_LOCAL) {
if ([AppUtils getNetType] == DISCONNECTED) {
_playInfo.status = STOPPED;
return;
}
if (type == BOX && _playInfo.isOutdoorMode) {
[[LTOutdoorPlayHelper sharedInstance] buildServerPlaylist:_playInfo.playlist];
}
} else {
//如果是本地推送，则需要更换当前的歌曲列表
if (type == BOX) {
[[AppUtils getLocalMusicManager] changeSvrTracklist:_playInfo.playlist.songs listener:^(LTResult *result) {
_playInfo.pid = _playInfo.playlist.pid = [[AppUtils getLocalMusicManager] getSvrPlaylistId];
[self play:song playlistId:_playInfo.playlist.pid seek:@"00:00" index:0];
}];
return;
}
}
[self play:song playlistId:_playInfo.playlist.pid seek:@"00:00" index:index];
}
