• leonlai sample premium content media available anywhere?

  Hi, I was wondering if there is a sample premium content (media file) posted anywhere, which can run only in the protected environment on Vista and not on XP. Something, I guess like the premium content stored on blu-ray and hd-dvd media.. Thanks, Sandeep If you want to try PE/PMP, use WMV. That's what we can use PE/PMP right now... A WMV with high definition can be called premium, too. For BD/HD No, no Media Foundation solution yet... No we do not currently have a publicly available sample. Can you elaborate on what you are trying We may be able to suggest you alternate ways to achieve what you are trying. -Sumedh ...Show All

• JasonDunham Set Cursor Image

  How can I add an image to the cursor I've tried: CursorManager.setImage(" file:///dvddisc/ADV_OBJ/cursor.png "); and CursorManager.Image=" file:///dvddisc/ADV_OBJ/cursor.png "; but that won't work. Also I've attached an optical mouse to the Toshiba's USB port but it doesn't seem to work but using the remote controller in cursor mode works. Thanks, it worked perfectly! This should work: CursorManager.setImage( "file:///dvddisc/ADV_OBJ/cursor.png" , 0, 0); where 0, 0, are the x,y coordinates of the hotspot of the cursor (so 0, 0 would be the top left corner of the cursor). Also cursor.png needs to be listed as a resource in the manifest and playlist. Hop ...Show All

• dustinto Tools and Resources for Authors

  I'm a professional web developer interested in iHD/DVD authoring. At this point it is pretty difficult to get going due to lack of tools and resources and documentation. I am proficient in xml and javascript, but this is a slightly different bird for sure. What I am trying to figure out is - are the lack of resources a symptom of being early to the process, or is it a symptom of the content authoring industry (proprietary thinking) Yes I've read all the *basic* documentation. But beyond that I haven't found any good resources for authoring (beyond Peter's blog). When I try that sample in the iHD simulator I can see the 5 buttons. But when I click on any one of those buttons I get the error: "VCP Catostrophic Failure Occured" ...Show All

• net_ravikumar Maximum number of output nodes

  Is there an undocumented maximum number of output nodes supported in Vista because I am having issues using more than 8 devices. I have developed an application using a tee node where I am creating a topology that contain sseveral output nodes. I have a total of 16 usb audio devices (Turtle Beach) using the standard usbaudio driver that I am testing with. Now, with up to 8 output nodes, everything works fine but as soon as I want to use a 9th device as output node, the application crashes. What is even more weird is that I can reuse the same first 8 devices as output node in other streams. But if I add a stream with a 9th device as output node and or create a new stream with the 9th device as the only output node, it crashes. ...Show All

• doener OT: Suggestions about gallery.live.com

  Several things stand out about this site, now that people are starting to use it. So, here's some suggestions: Implement some sort of language filtering. Although I have nothing against the use of non-English and think it's actually commendable than MS allowing it, I would rather filter out Gadgets that are of no use to me. Alternatively allow multiple languages in the Gadget description, or some form of language translation. Improve Gadget images. It would be great if you could attach screenshots, as well as the 100x100 icon. Do something about Gadget spam. "Vamos Strip Player" springs to mind, I'd hate to think how many times it's posted. Remove the 1000 character limit on the description field, and allow it to be rich text ...Show All

• Kamen How to use custom interface in PMP environment?

  Hi, all: I am trying to build a media playback system with PMP environment. I try to build my system without PMP first. But many custom interfaces are exported by my media source and MFT. Currently, I use those interfaces directly. But I want to know how to use those interface with PMP. 1) Is it necessary to write my components as DCOM 2) Will MF generate proxys of my custom interfaces automatically 3) Can I get those components which in PMP and use them Thanks Hi Fei-tian, > Is it necessary to write my components as DCOM Yes, you need to provide a DCOM proxy-stub for the interfaces you want to export from the PMP process to the application process. If you are declaring your interfaces using IDL, the Mic ...Show All

  How likely are we to get a graph edit replacement for Media Foundation This tool has proven itself invaluable when working with DirectShow and it would seem a must to have some kind of tool to build graph/topology with an application.

• jacknsa How to handle device lost with D3DDeviceManager ?

  Hi, all: How to handle device lost with D3DDeviceManager If device lost is happend, how to notify other modules to free and re-create hw resource with D3DDeviceManager Thanks Hi Fei-tian, I asked our D3D expert, and here's what he had to say: When the device is lost, everything works as it did previously until the device is restored. The EVR’s presenter is the only component that really knows of the device lost situation. When the device is restored, the D3D Device Manager owner calls IDirect3DDeviceManager9::ResetDevice, which invalidates all the handles. All clients of the device manager should have been polling using TestDevice during this time and TestDevice will now fail, as the handle is invalid. This is how ...Show All

• JavaBoy dxva2.0 vs dxva1.0

  Hi, I am trying to figure out how to update my dxva1.0 based application to dxva2.0. In dxva1.0, things seemed to be simple enough: IAMVideoAcceleratorNotify is implemented on the output pin of the decoder, and IAMVideoAccelerator is implemented on the input pin of the renderer. However, due to lack of documentation (I couldn't find it), I don't know how to map DXVA2.0 interfaces to the the decoder output and renderer input pins: Is IDirectXVideoDecoder implemented on the renderer input pin Is IDirectXVideoProcessor implemented on the decoder output pin How does IDirectXVideoMemoryConfiguration fit in The DXVA1.0 document gave an excellent example of the call sequence of dxva1.0 IAMVideoAccelerator calls. A similar example ...Show All

• vasudupe Is this posible with Media Foundation?

  Hey there guys, Im looking for clearification about a media playing scenario im trying to solve - so here goes: Say i have managed to encrypt and include a known media file (e.g. mp3) in another custom media file named "song.sd3k" Is it posible to tell Windows when an application is trying to play this file, to pass the file to an MFT when the file has the .sd3k extension, and is it then posible for an MFT to decrypt and pass a decrypted MP3 stream to the application which is trying to play the file. Im not asking how its done - im asking if it is even remotely possible in your eyes. I have been trying to do it with a DMO in Windows XP - but the Media Foundation sounds more capable of such actions - if any of you h ...Show All

• jkidd01 uncompressed YUV to EVR

  Hi, I am writing a simple YUV media source to take in .yuv bytestreams and send it to the EVR. I have modified the MFT_Grayscale to act as a dummy transform to copy the yuv samples to the EVR. I am also using the playbackFX sample for the player. I'm having a problem with the player just showing a black screen, as if no samples are being sent to the EVR. I have verified that the samples are being processed in the dummy transform with the correct image size and attributes for my given yuv sample. I have tried other yuv samples and all just display a black screen, but the samples are being processed for sure. Is there any way to debug this to see if the samples are being sent to the EVR Or does anyone have any clues why this is happeni ...Show All

• daniel mark codec selection for RTC SDK

  As i am using RTC (SDK) with C#. I found a bit problem with its default codec selection. As the best codec and the frame size will be selected for different conditions. The changes will happen dynamically during the call. But i want to do it manually i want to select my own codec among the available and supported codec list. So is it possible to do so if yes than how Hi Xishan, This forum is about Media Foundation, the new multimedia API for Windows Vista. Since you're asking about the RTC API, which isn't in the realm of multimedia, I don't know whether there's a newsgroup that would be most appropriate for your post. Here's a list of all newsgroups, in case there is one: http://www.microsoft.com/communities/newsgroups/list/e ...Show All
