Newbie: Video DSP beginner guidance "divya_rathore_[ at ]gmail.com" <divyarathore[ at ]gmail.com> 4/20/2007 7:19:40 PM I want to implement Video DSP for WMP 9 onwards (am hoping that things won't change too drastically in further version as far as handling the frame bitmap is concerned). Basically, I would like to implement simple DSP algorithms like blurring, denoising etc on each video frame while running from within Windows Media Player using WMP Plugins. How should I start? Some sample programs are available to begin straighway? Particularly one that can give me the pointer to the frame data (R,G,B components). regards, divya

The WindowsMediaPlayer SDK contains a wizard to create WMP plugins and DSP plugins are documented in the SDK. Notice that a DSP plugin is a DMO and generic DMOs are documented, with samples, in the DirectShow SDK, which is part of the Platform/Windows SDK. DMOs work with WMP7+ on XP. They might not work with WMP11 on Vista and you may need to write an MFT for it (but I don't know for sure - MediaFoundation is documented in the latest Windows SDK for Vista). -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm

I will look further into the A-B-C of DMO, MFT etc and revert back :) I understand that it would be a fine balance between signal processing and industrial terminologies/practices but worth a try, am sure. - divya

At least my video decoder MFT doesn't and MSFT support people suggest it won't at the moment. ..a
