There are several links to some online content in my app. and I want user to change the content from one to another with a button click. Since WMP spent some time while buffering for the next content, I want to continue playing the current content. There is an event called "Buffering"... 3 12/29/2008 2:16:15 PM IWMReader::Close crash I'm reading audio stream from some url (mms://). I can normally call Open(), Start(), Stop(), but when I call Close(), I get access violation. I receive WMT_STOPPED and pointer to WMReader becomes 0xfeeefeee. Any idea? ... 1 12/27/2008 12:44:07 AM ASF - Video Stream with 8 bpp Hello guys, I'm creating ASF files with a Video Stream of 8bpp, and a third party codec that was created by my team. When I create the Video Stream, there is no error but then the ASF Viewer shows me that the WMSDK is adding an "Extra Data Size" of 1024 bytes which are garbage bytes (the information of the audio streams). If I change from 8bpp to 16bpp, this behaviour disappea... 7 12/26/2008 9:52:31 PM DirectShow Plug-In For All Popular Video Editing Software Hi All, After three weeks of fiddling, I am finally streaming video over our LAN over a new type of protocol stack that runs in parallel to TCP/IP. The filter is a Source URL filter.The images come out at other end of the LAN up-side-down, but I think I can fix that. I would like to get my filter to load as a plug-in to all popular video editing software (Adobe Premiere, etc.). I noticed... 3 12/23/2008 6:12:38 AM Writing Windows Media script commands in DirectShow? Hi folks, I'm at my wit's end with this. I've created a profile with an audio stream, a video stream, and a script stream. I did this with the WM9 Profile editor, and the ConfigureFilterUsingProfile function on the writer filter seems to accept it. I've created a CSource filter that exposes a WMMEDIATYPE_Script stream, and it successfully connects to the script input pin on the ASF ... 2 12/23/2008 1:34:44 AM recordeing Encoder Stream to Disk Hello, I’m writing an application that uses the Windows Media Format API to read a stream, broadcast by Windows Media Encoder, and save it to disk. I’ve written a quick test application in C++ to test that this can be done. The app can open the stream but cannot save it, getting a FALSE output from the call to IWMReaderAdvanced4->CanSaveFileAs(). Can anyone point me in the right di... 4 12/22/2008 12:57:01 PM VC-1 StartAnalyze BeginWriting 2-pass Chicken Or Egg Conundrum I was wondering how to implement 2-pass encoding for video AND audio using WMF11 and the VC-1 sdk. From what I can tell it can't be done in one fell swoop, as it's a sort of "which came first, the chicken or the egg". For VC-1, you have GetCodecPrivateData which can only be retrieved after StartEncode. Yet, for the ASF profile, you can't set append the CodecPrivateDataSequenceHeader... 2 12/19/2008 5:41:00 PM Change mediatype in asf-file Hello! I am using the wmf sdk to create asf-files containing mpeg4 video. Everything works ok when I use VIDEOINFOHEADER to describe the video stream, but now I want to change to MPEG2VideoInfo. According to the documentation that should be possible? http://msdn.microsoft.com/en-us/library/aa392195(VS.85).aspx The problem is that the created asf-files seems to get a corrupt bitmapinfoh... 2 12/19/2008 5:36:46 PM Simultaneous playback during encoding with IWMWriter Hello, I'd have to write a hardware specific codec to write to Windows Media file format. SDK's UncompAVItoWMV sample was a good start point though I've encountered one issue which doesn't permit me to comply with the software requirements: - Writing content should be available for playout in a editing system. A file is being written in a share mode and can be opened by any DirectShow o... 2 12/19/2008 4:56:34 PM Video/Sound not in sync when embedded When embedded as a control into an application using AxWindowsMediaPlayer, on windows mobile 6.1, the video is much slower than when running as a standalone application. As a result, the video is still playing when the audio stream ends (they're not in sync at all). Anyone experiencing it too?... 1 12/18/2008 2:39:38 AM Setting AxWindowsMediaPlayer.windowlessVideo to true generates an exception... In my numerous attempts to get some video playback capabilities in my CF3.5/WM6.1 application, I finally managed to get something working by using the "Hosting a native windows control" sample from MS. However, when I set the windowlessVideo property of my AxWindowsMediaPlayer control to true, I get an ArgumentException. mp = new AxWindowsMediaPlayer(); mp.uiMode="none"; // I gave the c... 1 12/18/2008 1:18:04 AM WMV file created by IWMWriter not playing properly in wmp 11 My application converts a proprietary video file format to wmv file (using Windows Media Video 9 codec). Playing the WMV file using Windows Media Player 9 all seems to work fine, but if the same file is opened using WMP 11 seeking using the slide bar causes the video to hang, the slide bar resets to the beginning and starts moving forward. Once the slide bar reaches location dragged to ... 5 12/17/2008 7:26:01 PM WPD API in Vista x64? Hi, I would like to know if the WPD (Windows Portable API) can be used in Vista x64? I have successfully used the API on Vista 32-bit and XP 32-bit operating systems (via c# code) but when the same code is executed on Vista x64, it crashes when "GetDevices" is invoked.

However, there is some issue with this buffering - once buffering start event (MEBufferingStarted) is sent out to wmp, wmp stops rendering, and once the buffering end event is sent out to wmp, the playback resumes but the duration of buffering is added into the presentation clock. So... 1 12/11/2008 7:42:03 PM Runtime Error after creating object WMSServerClass --> code: 80040 hi.. I was trying to create a Window Media Server by using C#.

I had a hack to get the USB IDs for a portable MSC device that involved using CM_Parent on a Volume to get the USBSTOR device and again to get the USB device from which I could get the USB IDs. In Vista, the parent of a Volume is not the USBSTOR device. The WPD interface doesn't provide a way to get the USB IDs. This has always been an issue. Why is this so hard? How is an app suppossed ... 3 12/9/2008 8:45:01 PM DirectShow Custom URL Source Filter Fails To Load Hi All, I created a DirectShow Customer URL Source Filter to handle URL's beginning with FUBAR://...but I cannot test it because GraphEdt.exe will not load it when I do "Render URL."

I have been browsing the documentation for about an hour to learn how one would write a plug-in for a custom stream that is not based on HTTP. We have an old protocol that is like TCP/IP in principle, but is not TCP/IP, so it does not support HTTP. We have a server computer that needs to act as the source node of streaming audio/video data ... 10 12/3/2008 7:16:53 AM Windows Media Services plugin Hi, I need to write a C++ plugin for WMS that will grab the stream from a publishing point, parse the stream and save portions of it to file(s). Essentially I want to achieve the same result as the WMS Archive Data Writer but be able to control the archiving by saving desired portions of the stream and making them available while the publishing point is active. I've been looking at the... 8 12/2/2008 10:50:17 PM VB6 Hangs when adding a reference to the WMP.DLL Running on XPSP2 Visual Basic 6 SP5 I created a dll using the WMP.DLL I ran the application and it worked fine Now when itry to open the app in vb it hangs I rebuilt the applicationa and when I try to add a reference to the WMP.DLL vb Hangs Any ideas?... 1 12/2/2008 5:12:17 PM 13 Pages: 1  2  3  4  5  6  7  8  9  10  11  12  13
