• Wujek Szymon IMFPresentationDescriptor::Clone

  Hi, According to http://msdn.microsoft.com/library/default.asp url=/library/en-us/medfound/html/82db6f32-ad94-4563-b8bd-8a5072c5b221.asp , "To create the copy, call IMFPresentationDescriptor::Clone". Could anyone tell me why we need to call the member function Clone instead of AddRef Yes and yes. Say you're implementing IMFMediaSource::CreatePresentationDescriptor. You may not want to give the application a pointer to the same instance of the Presentation Descriptor that you are using internally, since you likely don't want to be randomly affected e.g. by whatever calls to SelectStream/DeselectStream or changing around attributes that they're making in their code.

• dax_kun OnChangeEvent.fire does not really fire event. (MS CRM server)

  I have very strange problem with MS CRM. Some client-side code are not working at client computers. Finally I traced it down to DHTML behaviour problem. In MS CRM we have IMG.lu.htc behaviour, which implements some kind of lookup control. To fill it I can eighter use a popup dialog (window) with list of values or use Form Assistant pane from the same page. On CRM New Case page I have a number of such lookups for different entities. Repro steps: Open new case, On new case form choose Account from Form Assistant pane (important !) Account field onChange is fired - but from this point no other lookup fields will fire their OnChange events. (while Account continues to fire it's own as intended) If you use any other lookup except Account ...Show All

• MattCollins audio/x-wav with attenuation

  Hi, Does attenuation work in HDiSim I've tried the following code: < object type =" audio/x-wav " src =" file:///dvddisc/ADV_OBJ/ding.wav "> < param name =" AttenuateL " value =" 100% "/> < param name =" AttenuateR " value =" 100% "/> </ object > Attenuation of 100% means silence, right Even if we do not set params like this: < object type =" audio/x-wav " src =" file:///dvddisc/ADV_OBJ/ding.wav "/> Specification tells us in 7.8.1-1 that default attenuation is also 100% i.e. silence again, right But HDiSim plays ding anyway.

• qt1h00 DMOs Operability in Media Foundation ?

  I thought I remembered hearing somewhere that DirectX Media Objects could be directly used by Media Foundation. However reading the current docs for Media Foundataion Transforms ( http://windowssdk.msdn.microsoft.com/en-us/library/ms703138.aspx ), it sounds as if you can implement IMediaObject on an object that implements IMFTransform but one cannot directly use DMOs in Media Foundation. Is this correct Thanks! Scott Hi Scott, You're right: The Media Foundation pipeline is prepared to handle Media Foundation Transforms (MFTs), not DMOs. And you're also right that if you write a wrapper for the DMO that you want to use that translates IMFTransform calls to IMediaObject calls, you should be good t ...Show All

• Haojun Determining 64-bit OS

  I have an app which reads from the registry to look for some registry keys written by a 32-bit app. When run on 64bit windows, the registry entries are under Wow6432Node.

• Bill Gates II Authoring software

  Hi guys.  Please excuse my more basic question that is not about advanced content. I have a SD DVD I need to convert to HD DVD.  I've used the now defunct DVD Maestro to do all my authoring and I am proficient with it.  I need a tool, preferably XP compatible, that will allow me to do some HD DVD authoring with that level of flexibility.  The only thing I know of is Scenarist and that may be a stretch for my pocketbook. Are there any other options   It is important that the authoring process does not do any recompression of the content. Thanks, Scott Denny, et.al: Thanks for the pointer. I'll look it over. I didn't understand teh comment about Sonics part. I was ...Show All

• Santosh A H Any method for MF PVP application fail gracefully if video driver is not PVP signed?

  I am working on an application that runs protected playback with Media Foundation. I've encountered a problem that with some graphics cards, an error dialog box pops up from another process saying " Bad Image: X is either not designed to run on Windows or it contains an error". After repeatedly pressing OK for the same dialog poping up many times, I can see the application hits a debug assertion saying that  ESP is not properly restored. I've read about the following previous thread in this forum and know that this symptom happens because video driver is unsigned and mfpmp.exe failed.
