视频如何等比例显示

你好，为什么我调用了才裁剪视频的接口后 我的视频显示并没有发生裁剪变化呢？
if (flagTimes == 1)
   ...

您好，请问你的SDK是什么版本？把日志发出来，在程序运行目录下（.log文件）

您好，你或者可以尝试下修改imageview控件的contentmode属性来达到裁剪效果，contentmode属性参考网址：http://blog.csdn.net/huifeidexin_1/article/details/8524507

你好，我的视频原料demo中两端都收不到语音。不知道是怎么回事。我的音频聊天和视频聊天是分成两个控制器写的，音频聊天有声音，视频聊天没有声音。
关键的代码应该是下面这部分吧？
// open local video[执行这段代码之后 会调用 OnLocalVideoInit[进行摄像头的初始化]]
    [AnyChatPlatform SetSDKOptionInt:BRAC_SO_LOCALVIDEO_OVERLAY :1];
    [AnyChatPlatform UserSpeakControl: -1:YES];//打开本地麦克风
    [AnyChatPlatform SetVideoPos:-1 :self :0 :0 :0 :0];
    [AnyChatPlatform UserCameraControl:-1 : YES];

    // request other user video
    [AnyChatPlatform UserSpeakControl: userid:YES];
    [AnyChatPlatform SetVideoPos:userid: self.theUIImageView:0:0:0:0];
    [AnyChatPlatform UserCameraControl:userid : YES];

2016-02-02 16:16:05.687 PartyConstructionSystem[1517:254335] 接受了对方的聊天请求，  ...

您好，从日志上分析是正常。请问，先进行视频聊天，再转到音频聊天，是否正常呢？

你好，音频聊天没有问题，只是进入视频聊天的时候两端收不到声音，切换的时候也是一样
