这个是针对 AliPlayer 的 trackInfos 的切换方式, 通过 URL 切换请直接前往 切换清晰度 查看.
#import <SJBaseVideoPlayer/SJAliMediaPlaybackController.h>
SJAliMediaPlaybackController *playbackController = SJAliMediaPlaybackController.new;
_player.playbackController = playbackController
// 当前视频的所有 track 准备好后, 查询它们中是否有可切换的 track
__weak typeof(self) _self = self;
playbackController.onTrackReadyExeBlock = ^(SJAliMediaPlaybackController * _Nonnull playbackController) {
__strong typeof(_self) self = _self;
if ( !self ) return;
SJAliMediaPlayer *player = playbackController.currentPlayer;
SJVideoPlayerURLAsset *curAsset = playbackController.media;
AVPTrackInfo *curInfo = [player currentTrackInfo:AVPTRACK_TYPE_SAAS_VOD];
NSArray<AVPTrackInfo *> *trackInfos = player.trackInfos;
NSMutableArray<SJVideoPlayerURLAsset *> *definitions = [NSMutableArray arrayWithCapacity:trackInfos.count];
// 查询其他清晰度的track
// 创建相应的asset, 用于切换
for ( AVPTrackInfo *info in trackInfos ) {
if ( info.trackType == AVPTRACK_TYPE_SAAS_VOD ) {
SJVideoPlayerURLAsset *one = nil;
NSString *fullname = [NSString stringWithFormat:@"清晰度 %@", info.trackDefinition];
NSString *lastname = fullname;
if ( info.trackIndex != curInfo.trackIndex ) {
// 创建其他清晰度的asset
one = [SJVideoPlayerURLAsset.alloc initWithSource:curAsset.source subTrackInfo:info playModel:curAsset.playModel];
one.definition_fullName = fullname;
one.definition_lastName = lastname;
}
else {
// 当前正在播放的asset
curAsset.definition_fullName = fullname;
curAsset.definition_lastName = lastname;
one = curAsset;
}
[definitions addObject:one];
}
}
self.player.definitionURLAssets = definitions;
};
