"x86"中的axWindowMediaPlayer dvd音频对比“任何CPU" [英] axWindowMediaPlayer dvd audio in "x86" vs "Any CPU"

问题描述

我在使用axWindowsMediaPlayer和DVD播放时遇到了这个问题，无法弄清楚为什么会这样.

I have this problem with axWindowsMediaPlayer and DVD playing and cannot figure out why this behave like this.

1.当我为平台"Any CPU"构建解决方案时，DVD播放OK音频，该音频以PCM编码，而那些音频以AC3(杜比数字)编码，则仅播放视频而听不到任何声音.

1.When I build solution for platform "Any CPU", DVD plays OK audio which is encoded in PCM and those which are encoded in AC3 (Dolby Digital) plays only video and cannot hear anything.

2.当我为平台"x86"构建程序时，问题是相反的. AC3可以，但是听不到PCM.

2. When I build program for platform "x86" the problem is reversed. AC3 is OK but cannot hear PCM.

我已经构建了如下所述的dll:http://msdn.microsoft.com/en-us/library/ms748870.aspx.如果我使用x86，任何CPU，...构建它，都没有效果.

I have build dll like described here: http://msdn.microsoft.com/en-us/library/ms748870.aspx. No effect if I build it with x86, Any CPU, ...

有人知道哪里可能出问题吗?或更佳的解决方案是什么?

Does anybody know where could be the problem? Or better what could be the solution of this problem?

过一会儿我才发现，构建到x86平台后，一切都可以在Windows Vista x64上正常运行，而不是在Windows 7 x64上运行

after a while I just figured out that after build to x86 platform everythings works fine on Windows Vista x64, not on Windows 7 x64

推荐答案

在Windows 7上，杜比(Dolby)按应用程序许可其AC-3音频解码器，而我们仅具有针对Microsoft应用程序的许可，这意味着它不能在 未经许可的应用程序将使用的平台.因此，我希望您不会听到使用以下方法从DVD中获得任何音频 Windows 7中的 axWindowsMediaPlayer .

On Windows 7, Dolby licenses their AC-3 audio decoder on a per-app basis, and we only have licenses for Microsoft apps, which means it can't be in the platform to be used by unlicensed apps. So, I am expecting that you will not hear any audio form the DVD using axWindowsMediaPlayer from the Windows 7.
