graphedit

问题 I'm trying to execute a code generated by graphEditPlus (using VS2010) but having a trouble with the following line: CComQIPtr<ISampleGrabber, &IID_ISampleGrabber> pSampleGrabber_isg(pSampleGrabber); where the errors are: error C2065: 'ISampleGrabber' : undeclared identifier error C2065: 'IID_ISampleGrabber' : undeclared identifier error C2514: 'ATL::CComQIPtr' : class has no constructors I tried downloading different versions of Windows SDK (V7.1, V6.0A, V5) and set the include / lib paths

问题 Currently I'm writing a DirectShow based application that should help users configuring their TV capture cards, since GraphEdit seems to be too difficult for most to understand. The idea is that this application exports the generated Graph to a .GRF file, that will be used in another application. Users can select which device (IMoniker) should be used to create a source filter, and can change some settings regarding video / audio. Next to exporting .GRF files, my application should also have

问题 I notice that avisynth can accept as input a "live directshow source" only through a graphedit file that includes that source in it. Is there any help tool out there to create a graphedit file on the fly, given you know a capture sources name (and/or the output format you want from that pin)? ref: http://betterlogic.com/roger/2012/05/avisynth-live-capture The graphedit file syntax is described here: http://msdn.microsoft.com/en-us/library/windows/desktop/dd388788(v=vs.85).aspx (though it

问题 I'm using DirectShowNet in C#. I've been developing an application to work with webcams to display video, change resolution, and take pictures (either Still pin or from the Capture stream). I've been testing it on 2 different machines (Win 7 64-bit & Win 8 64-bit) and with the internal webcams on those machines (they are laptops) and 2 other webcams, Logitech C920 and Microsoft LifeCam Studio. One day, the LifeCam Studio stopped working on my Win 8 machine. Using GraphEditPlus, checking the

问题 I Created a CTransformFilter, this is used to Resize the output video. It is working with default values which i gave in the code. Is it possible to make this filter receive values, i mean when i create Instance of this filter in my code is it possible to pass the values say like Resizer->width = 100 Resizer->height = 50 here Resizer is the filter. 回答1: You want to implement a "private interface" on your filter and then the controlling application will use it to communicate with the filter.

问题 How to reconnect Filter Pins? I created a resizer filter (c++) and added a property page with options Pal(720X576) and Ntsc(720X480).(default is Pal). In Graph Edit i selected a video file and added My resizer filter to it, when i played the graph it is working fine and showing video in Pal. when i tried to change it to Ntsc, it is not working correctly. To make it work correctly i need to first disconnect the Resizer filter pins and then change the output settings and then reconnect it.(i do
