The problem is to build a capture graph supported three states: Preview only Capture to AVI-file only Combine I have built the graph like this: This graph corresponds to state 3. Now, if I want to change on state 2 I remove the preview stream and get the graph like this: Imagine I run the graph and start capture. Now I want to back to state 3. How can I do this (add a preview stream) without stopping the graph? (Capture should continue). UPD. Maybe it will be possible to capture to the end of AVI-file? If so, I could stop the graph at state 2, add a preview stream to it (change to state 3) and

I'm very new to DirectShow and I'm looking for a way to render a video which is already loaded into the memory using DirectShow.NET. How can I do that? I'd be thankful even if you give me a highlight of the path. Roman R. There is no standard component to play from memory data, however Async Filter Sample from Windows SDK implements exactly this. The application reads the file into memory at the specified rate and plays the file. Note that the filter requires, however, expects some C++ development from you.

I should have to write a Direct Show Filter which takes input(video,audio) from live source. And it should give the data(video,audio : which are encoded) to a decoder Filter MyCustomDirectShowSourceFilter ---> Decoder Any real working examples which i can build my own source filter and any suggestion for implementation? Best Wishes Update: Basically i want a source filter which takes streams from network and let to handle the parsing and decoding of video stream by another filter. So when i modify Microsoft sample Push Source Filter and connect to a decoder it does not call FilllBuffer method.

I have a DirectShow graph with a "Microsoft DVBT Network Provider", "AVerMedia BDA DVBT Tuner", "AVerMEdia BDA Digital Capture", "Sample Grabber" and "NULL Renderer". These filters are connected. Beside that I also have an "MPEG-2 Demultiplexer" and a "BDA MPEG2 Transport Information Filter", but these two filters are NOT connected! It seems like they have to be here in order to run the graph. When I start the graph, I'm receiving TS data, but no matter what I do, I'm not able to put the tuning request. I can only capture the MUX data from the last tuned frequency with some other application
