确定MPMovieController比特率 [英] Determening MPMovieController bit-rate

问题描述

有没有办法确定MPMovieController正在播放的流的比特率？
我在iOS上的objective-c编程

Is there a way to determine the bit-rate of the stream an MPMovieController is playing? I am programming in objective-c on iOS

推荐答案

找到它，accessLog为您提供定期统计数据包括观察到的比特率：

Found it, the "accessLog" gives you periodic stats which include the observed bitrate:

MPMovieAccessLogEvent *evt=nil;
MPMovieAccessLog *accessL=[moviePlayer accessLog];
NSArray *events = accessL.events;
for (int i=0; i<[events count]; i++) {
    evt=[events objectAtIndex:i];
}
return evt.observedBitrate
