My application needs to open multiple AVI files, and I create a GraphBuiler then call RenderFile. But I cannot open more than 75 avi's.

Is this a limit fixed by DirectShow, is a parameter or other

Many thaks

Re: DirectShow Development Maximum numer of filtergraph

You are trying to play 75 videos at the same time Seems like a busy display.

What error do you get and what statement do you get it on

I need to preload a large number of avi, but not all videos are played togheter. Ther are grouped in "pages" (single windows) of 7-8 videos, that I show in different times (I need to switch instantly from one page to another).

For every avi I create a graph, then i call renderfile...not a complicated job. The error (0x80040295 - Certification failure ) appear on the 76 call to RenderFile, sistematically. It is not related to video file (it occurs even if I open the same file for 76 times)

Here my c# code (I use DirectShowLib):

...

this.graphBuilder = (IGraphBuilder)new FilterGraph();

hr = this.graphBuilder.RenderFile(_FileName, null);

DsError.ThrowExceptionForHR(hr);
...

Thanks!!!
