Is it possible to use the h264 and aac encoders that ship with windows 7 from directshow?

I see that windows 7 ships with an aac encoder and an h264 encoder. I'm writing a directshow application that needs to do video encoding. I think: "Great! Now I don't have to license a video encoder!", but then I read on to discover that these encoders use the new MFT api which seems to be incompatible with directshow, and there doesn't seem to be a wrapper filter like there is with DMO. Is there a way for me to use these filters in directshow? Maybe there's a wrapper I didn't find? Maybe I c开发者_Python百科an access these filters as DMO's?

As far as I know the H264 and AAC encoders are only available using the Media Foundation APIs. See the Supported Media Formats in Media Foundation on MSDN. So if you want to make use of these you'll need to use WMF instead of or in addition to DirectShow. As far as I know there is now wrapper or adapter to get a MF graph into DirectShow.

The good news is that MF is much improved compared to DirectShow and offers very nice higher level APIs for video like the SinkWriter which make it much easier to write video to a file.
