ISampleGrabber interfaces support it on WM5

            


WM5 of CameraCapture
saved to a file after the video captureI now want to get a frame by frame video capture after the original data, and then use my own coding library for encoding
(Ie, video capture data, I do not need the back part of the framework DShow, and I would like to direct the data VideoCapture of Filter outputted own processing)
DShow Windows on there ISampleGrabber interface, you can get the output buffer
FilterDo not know if I have a WM5, I feel like I did not find

I do not know I mean there is no clear expression
Is the video capture of this piece, I realized with DShow, but behind the encoding and transmission, I used my own code
It needs to have a connection in the middle of the process, would ISampleGrabber can be achieved, but I did not like on WM5 find this interface
I do not know there is no other way

Thank you :)

The landlord, now that the
Now researchers like me
I also want to get data from one frame of

It did not find ISampleGrabber

An estimated it might not be supported.

However, there are a IMediaSample interfaces which has GetPointer function
virtual HRESULT STDMETHODCALLTYPE GetPointer (
/ * [Out] * / BYTE __RPC_FAR * __ RPC_FAR * ppBuffer) = 0;

Inside SDK description: IMediaSample: Provides shared memory buffer functionality, holds some properties about the data, and holds a pointer to the data itself

I do not know whether to use this interface to replace ISampleGrabber ah

Haha, like beauty, is not supported. You can use Contrast that example.
