I want to develop a capture application for live streaming using H.264. I have earlier worked on Windows Media Encoder SDK and Format SDK, but I could not figure out how I can connect H.264 encoder directshow graph to Windows Media Services. I want to leverage the benefits of Smooth Streaming. Thanks, Neeraj Hi Alex, Thanks for the nice blog over Windows Media and Silverlight.

Do you have any sample code for how to accomplish this? I know the Player SDK has this functionality of smooth streaming sources but we are just dealing with progressive downloaders. I looked through the Player SDK code, but wasn't able to get a great grasp on it since it was obfuscated. It seems counter-productive for us to re-write a WMV file format parser if you guys already have one written. Is that something you could share? Let me know if you want to take the conversation offline. That makes a lot of sense, thanks. Do you have any sample code for how to accomplish this?

Smooth Streaming server is a completely stateless HTTP server. Slow motion is easy to do because on the lowest level SSME is implemented using the MediaStreamSource API which requires the video/audio samples to be parsed from the file format the container and fed to the MediaStreamSource interface to be decoded and rendered. You can set any timestamp on the video samples, so if you want to play a 30 fps source at 10 fps, all you have to do is change the timestamps so they're 100 msec apart.

How is the Slow Motion trick play done? Is that now possible with a standard SL MediaElement or is it all handled server side? Alex – very exciting stuff! How is the Slow Motion trick play done?
