问题
We would like to leverage the codec capabilities of DirectShow from Silverlight. Is this possible?
回答1:
MediaStreamSource is really the closest you will get to accessing decoders in Silverlight.
You also may want to look at this project: http://directshow4sl.codeplex.com/ It is a managed re-imagined version of DirectShow.
回答2:
In short (because I can't even think of a long answer) no, you can't use DirectShow in Silverlight.
