*音频/视频同步问题* [英] * Audio / Video Sync Issues *

问题描述

问候。

我正在使用带编码器4的Hauppauge 1250-PCI Express电视调谐卡。 视频和音频的来源是Hauppauge驱动程序。 编码开始很棒。  Silverlight预览窗口中的音频和视频都是同步的。 
但是，大约5-7分钟后，流不同步。 

I am using the Hauppauge 1250-PCI Express TV Tuner card with Encoder 4.  The source for both the video and audio is the Hauppauge drivers.  The encode starts off great.  Both audio and video are in sync in the silverlight preview window.  However, after about 5-7 mins, the stream gets out of sync. 

我可以重新启动编码并发生相同的行为。 一切都开始很好，然后5-7分钟后，不同步。 我尝试缓冲15秒，但没有运气。

I can restart the encode and the same behavior occurs.  Everything starts out GREAT, then after 5-7 mins, out of sync.  I tried buffering up to 15 seconds, but no luck.

任何想法？

我期待着您的回复。

干杯。

推荐答案

这很难，但可能是Hauppage有问题驱动程序，这发生在翻转摄像机，如果你有Windows 7上的驱动程序，你无法让音频和视频同步。 如果是这种情况，测试
的方法是删除Huppauge驱动程序，然后查看你的音频/视频是否会同步。

This is a hard one, but it may be that there is a problem with the Hauppage drivers, this happened with the Flip Video Camera, if you had the drivers on Windows 7 you couldn't get the audio and video to synch up.  If that is the case ,the way to test it is to remove the Huppauge drivers and then see if your audio/video will synch up.

不是这样的是Hauppauge的错，也不是微软的错，但它确实发生了。 这是对集成的测试。 如何在确定问题位置时进行修复，您需要回复一下您进行测试的情况，也许微软
Expression的人可以给出答案。

It isn't that it is Hauppauge fault, nor is it Microsoft's fault, but it happens.  This is a test of the integration.  How to fix when you determine the problem location, you would need to post back that you did the test and maybe the Microsoft Expression guys can give an answer.
