17.我用media encoder utility 8压缩的wmv的图像居然是反的,人物
都大头朝下了,这是怎么回事?是不是参数设置有问题?以前用wm8 beat2很正常的
呀。
答:可以参看下面微软的回答.....以下是在该产品帮助中的faq中有的:Why is my encoded video upside down when I
play it back in
Windows Media Player? Occasionally, encoded
video
will be upside down when it is played
in Windows Media Player because capture card
drivers interpret the packed YUV file format
in different ways. (是由于捕获卡驱动解释方面的原因)Windows Media 8
Encoding Utility enables you to set a
registry key that will flip the video before
encoding it so that it displays correctly.
By default this feature is disabled. To
enable this feature, use the registry editor
to locate the registry key HKEY_CURRENT_USERSOFTWARE
MicrosoftScrunchWMVideoVertical
Flip Packed YUV, and then set the DWORD
value of
this registry key to 1。(即可以将以上键值改成1解决)
18.请问怎样把asf和wmv转换成avi的文件?
答:如果可以用virtualdub1.3c(或者支持asf的1.4版也可以)打开的话,就
简单了,video/audio都选择direct stream copy,然后save as成avi
就可以了。不过vd好像对于asf支持的好一些,我试过对付wmv好像不行。另一种方法
是用graphedit来转换,这种方法通杀wmv、asf。
19.装了windows media player7.0之后,我还可以用windows media
player6.4版本么?
答:当然了。那个6.4版本已经被升级成了6.4系列的最高版本了。这个程序的位置是C:Program FilesWindows Media Playermplayer2.exe。
