I wrote a program to play MPEG video on a window (of course, DirectShow will open its own window as the sub-window of that window). On Windows Vista and 7, the program works fine. But on XP, the video is only visible when I set the WS_CLIPCHILDREN style on the outer window (i.e. not the DirectShow one). Is this a bug in XP or some model ...
I want to read an mp3 file, crop section of it, fade in & out and finally save it as a new mp3 file. I found a library called DirectShow that apparently can do this, but I can figure out how to do it. Has anyone done something like this? ...
I have a DirectShow source filter for receiving a Network stream containing RFC2435 data (MJPEG over RTP). The properties of the source filter's output pin need to be set-up prior to receiving the stream which is the only source of the image's dimension data. The dimensions for the output pin are currently set to some default values (...
Hi ! Pbm: I have a device that shows a microscope capture through usb port device interface. I would like to capture the video flow to process the images for research purposes. I've tried several available codes with directshow that works for webcams and similar devices but they don't work because the interface device is not known. Is ...
Hi, I have made a sample application which constructs a filter graph to capture audio from the microphone and stream it to a file. Is there any filter which allows me to stream to a memory buffer instead? I'm following the approach outlined in an article on msdn and are currently using the CLSID_FileWriter object to write the audio to...
I need put one bitmap image to my directshow filter. Then user can use this bitmap image and do not care where is it. First, I import this bitmap file into resource bundle, and get one IDB_BITMAP1. Then, I need to read this IDB_BITMAP1 using opencv cvLoadImage or some windows image API to load this image into buffer. So question is h...
Below is the code extract from my decoder transform filter which takes in data from my source filter which is taking RTP network data from an IP camera. The source filter, decode filter can dynamically respond to changes in the camera image dimensions since I need to handle resolution changes in the decode library. I've used the 'Rec...
I'm trying to debug my DirectShow source filter. I'm using Delphi Pro 6 on Windows XP along with the DSPACK component library. I'm using Skype as my host application, which I set in the Parameters option in the Run menu, for testing my source filter DLL (ax file extension). Skype runs fine and I see a stream of my OutputDebugString me...
I am attempting to use DirectShow to play two AVI files consecutively (one after the other) so that there is no interruption in the audio or video when the player transitions from one file to the next. I have two custom controls on my form. Each one is pre-loaded with an AVI file, and before playback begins I set up all the DirectShow ...

Today I have such graph. I run it on windows I need some easy crossplatform DirectShow like alternative where to reconstruct such graph will not be a hard task. Where can I get such alternative? *(and If you can presenta way to reconstruct such graph in It It would be grate!) BTW: By crossplatform I mean Linux Mac and Windows compa...
HI, I want to keep watermark into my video. How can i implement it using Directshow. Is it possible to create a filter for this. i want to fix watermark at the time of saving video to my machine. PLease give some suggestion and help ...
I am trying to do a few things using DirectShow for audio playback. I have a header file, at the top is: #pragma once #include <dshow.h> #pragma comment(lib, "strmiids.lib") and then it goes on to define a class. When including dshow.h I get the following complilation errors: C:\Program Files\Microsoft SDKs\Windows\v7.0\include\dd...
I have a DirectShow filter created with Delphi Pro 6 and the DSPACK direct show library. I'm running under windows XP. I've tried creating the form dynamically when the container class for the DirectFilter has its constructor called, passing NIL into the constructor as the AOwner parameter (TMyForm.Create(nil) and then calling the Form...
Hi, I'm now building a video transforming filter that have to transform video frames in real-time. One of the key requirements of the filter is to have high performance to minimize the number of dropped frames during the transform. Another requirement that is of lower priority but also nice to have is to make it cross-platform (both PC...
I've written a DirectShow push filter for use with Skype using Delphi Pro 6 and the DSPACK DirectShow library. In preview mode, when you test a video input device in the Skype client Video Settings window, my filter works flawlessly. I can leave it up and running for many minutes without an error. However when I start a video call aft...
