      • I have a DirectShow app that builds a filter graph with the (among others) audio capture filter of the mic. The data is sent over the network. The problem is that the microphone filter sends its data 2 times a second. So if I work at a rate which requires transmitting 44100 bytes a sec, I get 22050 bytes every 0.5 seconds.

At the same time, I must say that I was surprised with the non existence of the architectural and design documentation. Based on the fact that this is a brand new framework (WF) and based on the fact that huge number of us would like to start using it ASAP, it would be

      • hi, I have a HDTV capture card that always combines two fields into a frame, i.e., it will generate a 30fps video at 1920x1080 for a 1080/60i input. The interlacing effect is very noticeable in the video render. Is there any existing de-interlacing filter for DirectShow The only one I found online (from alparysoft.com) does not work with HD (it seems). Note that I need a real-time solution.

      • Our installation depends on a number of merge modules (mscomctl, mscomctl2, etc). The files in these modules are required by our software because our software still needs to run on Win9x (gasp!) and those OSs don't have the DLLs/OCXs installed by default. Our application also needs to be Vista certified. Test Case 15 says no files can be put into the System32 folder, yet the merge modules put the
