I'm trying to use GMFBridge to switch between multiple stream buffer graphs and I seem to have two problems. Here's a diagram of the graphs: http://massivefailure.net/dshowgraphsalt.jpg The VMR on the the bridge source graph that's connected to the bridge render graph is very choppy -- displaying a new frame every 4-5 seconds. If I se...
I am trying to understand a DirectShow library implementation. What is a IEEE1394-id in DirectShow terminology? IEEE1394 is firewire. Does it usually also describe ids for USB devices? it gets retrieved by IAMExtDevice::get_ExternalDeviceID() ...
I have created a custom allocator/presenter that works fine for playback of normal media files. However, when I use the following code to try to playback a DVD, it fails with a stack overflow exception. vmr9_ap = new vmr9ap(); HMONITOR monitor = MonitorFromWindow(hwnd, NULL); IGraphBuilder *graph; IBaseFilter *filter; IDvdGraphB...
I'm looking for the interfaces in DirectShow that will let me push a frequency only. The IAMTVTuner interface allows you to 'put_channel' but this requires pretuning your card. I want to just specify the frequency to tune to. Is this possible with analog? (you can do it easy with the interfaces for digital streams however). ...

Hey, So, I have an application which streams two video sources over a local area connection. Each video has its own filter graph, puts the video through a decoding filter, and an Inifinite Pin Tee filter, and then there is a GMFBridge filter, which is used to turn on/off recording using the WM ASF Filter. There is also a video renderer...
Hello I create my custom WM encoder profile. The reason I need a custom, non standard WM profile is that I need that the video resolution must be the same as input video stream. I created below profile but after I encode my video and audio with it, the WMP while loading says that the WMV1 codec is not found and prompts me for downlo...
I have a live 16-bit gray-scale video stream that is pushed through a ring-buffer in memory as a raw, uncompressed byte stream (2 bytes per pixel, 2^18 pixels/frame, 32 frames/sec). (This is coming from a scientific grade camera, via a PCI frame-grabber). I would like to do some simple processing on the video (clip dynamic range, color...
Hi, I'm trying to install a DMO which requires me to write to HKCR\DirectShow\MediaObjects\Categories\57f2db8b-e6bb-4513-9d43-dcd2a6593125, this registry path is protected by TrustedInstaller and it seems that this protection is new in Windows 7 (it work on previous platforms). How am I suppose to install DMOs? There are plenty of p...

I have write a DirectShow video transform filter, which is inserted between a video decoder and a video render filter. It will add a photo frame around the input picture. So the output picutre's size and aspect ratio is different from the input one. Unfortunately, I found the video render would maintain the original aspect ratio and so...

I need to find a video filter in order to mix multiple video streams (let's say, maximum 4). I've found a video mixer filter from MediaLooks and is ok, but the problem is that i'm trying to use it in a school project (for the entire semester) and so the 30 days trial is kind of unacceptable. So my question to you is that: are you aware ...
Hi, I am trying to develop a DirectShow filter with internet access. When I try to use Winsock, 1) In TCP, I wait connections but cannot access to server (try with Telnet) and 2) In UDP in data wait step (recvfrom(...)) program breaks. Is it not possible? Or do I have to change library settings for the filter? ...
I'm developing a custom video capture application. The idea is to capture output from a webcam, and simultaneously display a delayed preview. For instance if a user specifies a delay of 5 minutes, after 5 minutes of video capture the video preview will star playing what was captured 5 minutes ago, and will keep playing until five minu...
Hi all. I'm trying to create an ASF file and instead of using sound or video data I want to create a stream made of custom packets with binary data. Can someone provide a code example of a couple of things : 1) setting up a profile. 2) configuring a custom stream 3) inserting custom packets into the stream. Much appreciated. Thanks! ...
