iphone8 plus 系统14.2 导出视频经常失败

[MiTuShuSheng2019]

上面是截图，下面是代码

#pragma mark -- 开始转换视频
-(void)convertVideoWithAsset:(PHAsset *)asset{

__block CGFloat duration = asset.duration;
//根据PHAsset 获取视频相关信息
PHVideoRequestOptions *options = [[PHVideoRequestOptions alloc] init];
options.version = PHVideoRequestOptionsVersionCurrent;
__weak typeof(self) weakSelf = self;
[[PHImageManager defaultManager] requestAVAssetForVideo:asset options:options resultHandler:^(AVAsset *asset, AVAudioMix *audioMix, NSDictionary *info) {
    
   //  asset  这里有时候会返回空的
    if ([asset isKindOfClass:[AVURLAsset class]]) {

      
    }
}];

}

可参考最新版的requestVideoOutputPathWithAsset，这个方法支持iOS14

可参考：#1073
