问题描述
我有一个可以从两个设备编码的应用程序，并且通过EES自动将这两个信号保存到两个不同的wmv文件，然后我将使用两个wmv文件在pic文件中进行pic，但有时候在
a之后完成任务失败了。特定网站在哪里
Hi,i have an app which can encode from two devices and save the two signal to two different wmv files automatically on timer by EES,then i will do pic in pic file using the two wmv files,but somtimes it is failed to finish the task after a while.The particular site is where
" mRenderEngine.WaitForCompletion（）"此 方法永远不会返回 在照片中拍照。
谁能告诉我哪里出错了？我猜是
关注编码，但令我感到困惑的是为什么somtimes 在pic文件中做图片失败或成功使用文件由selfsame编码参数创建的。
"mRenderEngine.WaitForCompletion()" this method will never return when doing pic in pic .
Who can tell me where is wrong? I guess it is concerned with the encoding ,but i am puzzling why somtimes doing pic in pic file is failed or successed with files that created by selfsame encoding parameters.
谢谢！
推荐答案
我不确定我理解，所以让我验证一下。您使用两个不同的应用程序同时从两个设备实时捕获。这将它们保存到本地wmvs。然后，您尝试重新编码它们，一个作为视频叠加层。这是正确的吗？
I'm not certain I understand so let me verify. You are live capturing from two devices simultaneously using two different apps. This is saving them to local wmvs. You then try to re-encode them, one as a video overlay. Is this correct?
您使用的是Expression Encoder 4 SP1吗？如果不是，我会首先建议升级。
Are you using Expression Encoder 4 SP1? If not I would first suggest upgrading.
您是否正在尝试重新编码为图片中的图片，而设备仍在流式传输？如果是这种情况，这可能会导致您的问题。我不熟悉WaitForCompletion（）方法。这是自定义函数吗？
Are you trying re-encode as a picture in picture while the devices are still streaming? This could cause some of your issues if that is the case. I'm not familiar with the WaitForCompletion() method. Is that a custom function?
