流媒体播放器-阿里云开发者社区

显示下载进度条，支持边下载边播放。想支持边下边播放需要把视频文件放到指定类型的服务器上，服务器不支持流媒体类型无法支持该功能。

支持整屏播放和缩小屏幕播放。

整屏播放示例：

    BGVideoPlayerContainerView *vpcView = [[BGVideoPlayerContainerView alloc]initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.height, [UIScreen mainScreen].bounds.size.width)];
    [self.view addSubview:vpcView];
    [vpcView updateWithWaitTime:[self.entity.watch_video_minutes integerValue] urlVideo:self.entity.part_course_video logo:nil playImage:[UIImage imageNamed:@"play_icon"] isShowPlayTime:NO isStartPlay:YES];

缩小局部播放代码示例：

-(BGVideoPlayerContainerView *)vpcView{
    if (!_vpcView) {
        _vpcView = [[BGVideoPlayerContainerView alloc]initWithFrame:CGRectMake(0, 0, sCommonUnitFullWidth(), 217.5*FULL_WIDTH/375)];
        [self.contentView addSubview:_vpcView];
    }
    return _vpcView;
}

[self.vpcView updateWithWaitTime:waitTime urlVideo:videoUrl logo:logo playImage:[UIImage imageNamed:@"play_icon"] isShowPlayTime:YES isStartPlay:NO];
