旁路录像(边推边录)

旁路录像是指在开始推流之后, 启动录像可以将推流的视频内容同步保存为本地文件, 也称为边推边录. 目前支持保存为本地的MP4文件和flv文件. 必须要启动推流后才能开始录像, 结束推流时, 会强制停止录像.

启停旁路录像

在推流的基础类中和启动和停止推流的API, 平行的增加了一组启动和停止旁路录像的API

    _bypassRecFile =[NSHomeDirectory() stringByAppendingString:@"/Documents/rec.mp4"];
    NSURL *url =[[NSURL alloc] initFileURLWithPath:_bypassRecFile];
    [_kit.streamerBase startBypassRecord:url];
    // ...
    [_kit.streamerBase stopBypassRecord];

旁路录像状态监控

• 通过状态属性来查询当前旁路录像的状态

KSYRecordState bypassRecordState;

• 通过状态回调函数来接收状态变化通知

_kit.streamerBase.bypassRecordStateChange = ^(KSYRecordState state) {
         [self onBypassRecordStateChange:state];
};

 - (void) onBypassRecordStateChange: (KSYRecordState) newState {
     if (newState == KSYRecordStateRecording){
         NSLog(@"start bypass record");
     }
     else if (newState == KSYRecordStateStopped) {
         NSLog(@"stop bypass record");
         [self saveVideoToAlbum:_bypassRecFile];
     }
     else if (newState == KSYRecordStateError) {
         NSLog(@"bypass record error");
     }
 }

录像文件时长查

通过如下接口查询, 返回结果是单位为秒的浮点数

_kit.streamerBase.bypassRecordDuration;

注意: 由于是将录像的内容保存在本地, 请注意限制时长, 避免手机存储满.
