Cannot Connect Sample Grabber

I have downloaded your demo project and it seems that without making any changes to the original code, it does not show the volume levels of my mic. Thanks again! The camera can provide video in different formats and resolutions. For video rendering, the output buffer is likely to be located on the graphics card, where read operations are much slower, compared with read operations in main memory. http://electrictricycle.net/cannot-connect/cannot-connect-sample-grabber-capdvhs.html

The first (preview) i did using samplegrabber. I then used GraphEditPlus to construct a graph and generate the code in C#. wasifmirza commented Jan 17, 2015 import java.awt.Dimension; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; import javax.swing.JFrame; import java.awt.*; import com.github.sarxos.webcam.Webcam; import com.github.sarxos.webcam.WebcamPanel; public class Camera extends JFrame { JFrame cam=new hodka commented May 11, 2013 Hi, just tried the 640x480 after a reboot of my Windows XP machine. http://geekswithblogs.net/lorint/archive/2009/01/02/128316.aspx

This operation failed because the QueryInterface call on the COM component for the interface with IID '{6B652FFF-11FE-4FCE-92AD-0266B5D7C78F}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 In terms of the issue you found, to avoid such situations, I think I should remove all non-standard resolutions from the supported set, thus I would leave only QQVGA, QVGA and

I created it in lately so it does not have distribution ZIP yet, but I can release it if someone would like to try it. https://msdn.microsoft.com/en-us/library/windows/desktop/dd407288(v=vs.85).aspx Keep it up and all the best for the future development!

I can see there, that DivX H.264 Decoder is used to decode source file. Well, almost. This article describes buffering mode. (Before using callback mode, be aware that the callback function must be quite limited. Thanks for the prompt reply!

If recording works, than the dump might be useful to find the cause because for cueing the same graph would be expected. navigate to this website like DirectX must be version 11, etc. While .Net performs all the necessary magic to call and be called by COM objects, having unmanaged code make calls to a c# method... I think that the higher sample rate for audio is the cause of the problem.

You could see me as thedeemon on reddit or LiveJournal. I can step into other parts of the unmanaged code or place breakpoints in the unmanaged code with _asm int 3. Below is the code snippet from the DirectX SDK code sample: STDMETHODIMP CSampleGrabber::SetCallback( SAMPLECALLBACK Callback ) { CAutoLock lock( &m_Lock ); m_callback = Callback; return NOERROR; } Does the C# SetCallback

I'm not quite sure where my C++ filter would be calling C# code, I thought it worked the other way around.

Seek to the desired time, run the graph, and wait for the EC_COMPLETE event.

But when I tried to build it for several .mp4 files, I had a problem (common for all of these .mp4 files).

AMMediaType media; int hr = 0; media = new AMMediaType(); media.majorType = MediaType.Video; media.subType = MediaSubType.YUY2; media.formatType = FormatType.VideoInfo; hr = sampleGrabber.SetMediaType(media); DsError.ThrowExceptionForHR(hr); DsUtils.FreeAMMediaType(media); media = null; hr = sampleGrabber.SetCallback(this, 0); If you need your app to be portable and running on many operating systems, then you should still use default one, but if you do not need it to be portable, In this case I want to invert each pixel's intensity (luma) while keeping color (chroma) intact. click site Thanks for the great informative post and you effort.I think the above article is valuable for all concerned people.

The missing sln file is not the problem. If you would like to refer to this comment somewhere else in this project, copy and paste the following link: snarfle - 2010-10-01 It appears to me that this code will Then the grabber might be in time to get the next frame. Webcam.setDriver(new GStreamerDriver()); The other option is to use LTI-CIVIL Webcam Capture Driver which also use some unique streaming method, but there is no guarantee it will be working.

The Sample Grabber is more flexible, however, because it works with nearly any media type (see ISampleGrabber::SetMediaType for the few exceptions), and offers more control to the application. Thank you .I've bookmarked this page for my reference. To activate buffering, call ISampleGrabber::SetBufferSamples with a value of TRUE. Here is the log for the same application start, both after a reboot, once doing well and once failing: OK ***** VIDEOINPUT LIBRARY - 0.1995 - TFW07 ***** VIDEOINPUT SPY MODE!

However I still cannot step into the StepCallback() method in C#. What's really important is media major type, subtype (MEDIASUBTYPE_YUY2 in my case) and resolution.
