• Charles Lewis How to get/set the Bottomup value of a sample?

  As you know in the DMO we are using BITMAPINFOHEADER to describe some video information. In the BITMAPINFORHEADER, if the bmiHeader.biHeight > 0, the data is organized as bottom-up; otherwise, the data is organized as up-bottom. But in MFT, how can we assign the value You don't need to specify top-down/bottom-up in the media type. When you get the buffer, QI for IMF2DBuffer. If the buffer supports IMF2DBuffer, the IMF2DBuffer::Lock2D method tells you the stride of the buffer, which is >0 for top-down or <0 for bottom-up. (It will almost certainly be top-down in this case, because it will be a D3D surface.) If the buffer does not support IMF2DBuffer, then it uses "GDI rules", ie, bottom-up for RGB ...Show All

  Is there any Media Foundation Team blog. Or maybe individuals blogging about it. I have been doing quite a bit of development using it and it would just be fun to read about what is coming up and what not. Marc Hi Marc, Thanks for suggestion but unfortunately there isnt one right now. I very much want to start one but I am holding back just because we are in the final stages of Vista. I will definitely post a message here when we start one! Thanks, Prakash Channagiri ...Show All

• vzzvzz How to get a topology node's friendly name?

  I am writing an application that needs to reveal the details of a topology. Q:How can I get the friendly names of File/URL Sources, MFTs and a Media Sink(Renderer). eg: Enhanced Video Renderer to Video Media Sink - everything like what shows in graphedit.exe in direct show. There seems to be no direct member functions of IMFTopologyNode to display friendly names and I've tried to get the attribute by using IMFAttributes, however, I couldn't find appropriate GUIDs to accomplish this. And I couldn't find any function call like IBaseFilter::QueryFilterInfo used in DirectShow. Yup, I did use that "whenever possible" qualifier on purpose :-) I bet you're looking at the decryptor node. In a ...Show All

• Jose A. M. yet another doubt on unsetProperty

  Hi .... Consider this : CASE 1 ) In markup I have : <div id = "diva" > </div> In Script : document.diva.setProperty("x","100px"); document.diva.unsetProperty("x"); Assume no animation on "diva" :::::::::::::::::::::::::::: This will cause the div to have style:x = 100px since style:x is not explicitly specified (in xmu ) by the content author and hence even after unsetting the style:x its value persists . CASE 2) In markup I have : <div id = "diva" style:x="20px" > </div> In Script : document.diva.setProperty("x","100px"); document.diva.unsetProperty("x"); Assume no animation on "diva" :::::::::::::::::::::::::::: This will cause the div to have style:x = 20px since style:x ...Show All

• Wil Burton Audio Device Enumeration inconsistent in Vista

  Hi, I have build a application which enumerates all the audio devices installed in the system and searches for a particular PnP audio output device. To provide this feature I make use of 'DSPROPERTY_DIRECTSOUNDDEVICE_ENUMERATE_DATA' data structure. I populate this data structure and register it with dsound.dll. As a result of it a callback registered by me is invoked depending upon the number of audio devices present in the system. This approach is working perfectly find in Window's XP and 2K. But on Windows Vista (32 bit) I am facing some unique problems. Though there are 2 audio devices present in my system but sometimes the callback registered is invoked just once. Hence I loss the other device. What may be the reason for this Followin ...Show All

• StumblingInTheDark Gadget Piracy

  Vista hasnt been out for long but we are already seeing a big issue relating to gadgets which is piracy. I have already seen probably 5 examples of people taking someone elses gadget, making a few changes and re-releasing it. I have been developing widgets/gadgets for Mac OS X and Yahoo Widget Engine for 2 years now and i dont think i can even think of 5 similar cases in that time. As far as im concerned unless a gadget specifically states that you may modify and re-release it then those people are breaking copyrights. Just because you can view the source of a gadget that does not mean it should be considered open source in a typical sense. I've released more then 25 widgets/gadgets over the past 2 years and ive never had a proble ...Show All

• Andrew Buyan Question about WMP 10 SDK in VB2005

  This may be a stupid question for this forum, if so my apologoes... I am writing some simple code hosting WMP 10 in VB 2005 and I am trying to take advantage of the "playstatechange" event. This code works fine on the first pass, but on subsequent events, WMP starts playing, but then goes black upon exiting the subroutine... Just curious where I might go for some assistance on this issue. A code snippet follows: Private Sub AxWindowsMediaPlayer2_PlayStateChange( ByVal sender As Object , ByVal e As AxWMPLib._WMPOCXEvents_PlayStateChangeEvent) Handles AxWindowsMediaPlayer2.PlayStateChange If e.newState = 1 Then AxWindowsMediaPlayer2.Ctlcontrols.play() End If End Sub <-----we die ...Show All

• AshN How to combine DShow filters and IWMWriter together

  Hi All, I read all the post on IWMWriter and DirectShow stuff here and I am still having problems on how to mix them together (Obviously IConfigAsfWriter and related interface used in Asfcopy project is fading away..., so we are not going to use them much longer): 1) Can we add IWMWriter to the directshow filter graphs directly 2) If #1) is out of questions, how can we convert encoded avi files (compressed) to the WM file (WM files) by using IWMWriter 3) Lets say this AVI file has both audio and video output and If we have the sample grabber for both the Audio and Video pin, how could we mix it back together when we write to the WMV files Thanks you very much in Advance!

• edward1028 Can XPath variables be used in <styling>

HI there Xpath variables are meant to be used only inside Xpath Expressions (that's why they are called Xpath Variables :) ).
