Devoloping WMP "Achmed" <Bachmed[ at ]sadat.co.jd> 5/23/2007 5:36:37 PM I'm a C++ developer. I want to develop an WMP like application. Especially I'm interested in receiving nad/or playing HTTP stream video from a WME. Can someone refer to some code examples? Regards Achmed

The DirectShow SDK is included in the Windows/Platform SDK and contains extensive documentation and several samples. To play back an MMS-over-HTTP ASF streams coming out of WME9, you need to use the old WMSourceFilter or newer WMASFReader filter (under the right conditions, the filter is selected automatically). Notice the WMP however uses its own WM source filter, which behaves somewhat differently. Both the WMASFReader public filter and WMP's private filter internally use the WMReader object in the WMF runtime (but you can not use the WMReader directly in DirectShow, hence the need for one of the stock wrappers or a custom one). -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm

Can you direct me with some reference? Using DirectShow to play the WME stream takes a page of code, you should take a look at the introduction to DirectShow in the docs. Even just fetching the stream from WME9 requires you to use the same components (or the WMReader directly) because MMS-over-HTTP is not plain HTTP. Of course you could reverse-engineer the undocumented MMS-over-HTTP protocol (or take a look at some docs and source code from people who reverse-engineered it before) but, beside being doubtfully legal depending on which country you live in, it will be far more complicated than reading a few pages of DirectShow or WMF tutorials. -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm
