How about placing return NS_OK; after AfxMessageBox((LPCTSTR)"never show",MB_OK,-2); gr. Pjotr

Hi, Thnx for the reaction. I must admit I was expecting the question about the 'screenshots' I'm kind of using MJPEG compression, without the M. :) We have a defined format regarding directories and filenames, so I can uniqly indentify every image. This is done to be able to display...

Hi, I'm using a XP Pro (sp2) machine to record video in jpg format. I'm writing huge amounts of jpg files to a (spanned) volume. After I've written many files (varying from 150GB to 340GB), the machine stops recording. Indicating an invalid path to a file. If I reboot, the computer just...

Hi, I do use a linear scale, but it is translated to a logarithmic value. This section has been doublechecked many times. but thnx for the suggestion gr. Pjotr

Hi, I've resolved some timer issues. Put the PresentationInterval on D3DPRESENT_INTERVAL_ONE and it's 'working'. On high frequenties, you can sometimes see a small hickup on the display, suggesting a incorrect image (the wrong one) on the screen. hope someone can use this info.... gr. Pjotr

Hi, We' re currently developing a 3D sound system for a driving simulator. But we having difficulties with the volume of the sound. If a sound (other car) passes our own car, it's volume is very low. The factors aal are set to 1.0 (Rolloff, doppler and distance) If we set the rolloff to 0.0...

Hi, It seems to work, at least for slower refresh rates. If I use it at 75 Hz. Some v-syncs are missed and the screen does not refresh for 2 v-syncs. Since we want to measure the decay of the screenfosfors, we need to make sure our application only displays a picture (or a white screen) for one...

Hi, I' am programming a monitor testing programm. I need to switch images during a v-sync. I would like to use DirectX if possible, but I need to make sure I display only 1 image between v-syncs. Anyone have some suggestions. Does anyone know if the D3DPRESENT parameter will force this...

Hi, You can also look at DirectSound. With this lib you can pan (L/R) sound and select a device(soundcard) to load a sound to. You can probably achieve the same in DirectMusic. Pjotr

Hi, Does anyone know a simple way to wait for the v-sync and then blit some images. I have to blit two times two images during every v-sync (so i have four images in total). I know DirectX has a way to wait for the v-sync, but some people told me this method uses a lot of resources since it's...

Hi, I'm building a Filter with two input pins. I need to synchronize both input to make a calculation based on the two incomming IMediaSamples. Can someone give me some pointers or samplecode to achieve this? thank you, Pjotr

Hi, Have you already looked at framestepping in the DirectX SDK? Look under: DirectShow Reference -> Interfaces -> IVideoFrameStep greetings Pjotr

Hi, I am developing an DirectShow In Place TransformFilter using DirectX 9. I want to use the message map and classwizard supplied by Visual C++ to control the properties page. I can create controls and underlaying classes and variables with the classwizard, but the variables aren't used in...

Thnx All, already solved the problem by using malloc. greetings Pjotr

Hi, I want to create a large Array in Visual C++. I have an array of [256][256][256] containing a 3 Byte value. It compiles, but I get an error in runtime. (Yes I know it is an array of 48 MB) Does anyone know of a way to create a large array without the runtime errors? thnx Pjotr

Hi, Does this behaviour also occur when playing files in GraphEdit? Pjotr

Hi, Also the URL looks a bit strange. Is it a local Network playing the movie? And it is using the http protocol, which I find a bit strange. I suggest to use another source in your FilterGraph like...

Hi, You don't have a clue in what format the video is broadcasted? If not, open the stream in the windows media player and look at the properties of the stream. If I'm correct, the mediaplayer lists the filters used by its filtergraph. You can reconsturct these filters in graphedit and try to...

Hi, I am more skilled in the video part. I haven't used Direct3D that much. Not yet anyway. Good luck, Pjotr

Hi, Thanks for the star. It's my first :-) Pjotr
