c++ - Write to Directshow source filter

Question

I have got a directshow source filter which is based on http://tmhare.mvps.org/downloads/vcam.zip. I want to write the webcam frames that has been manipulated using opencv by my (separate) application, to this virtual webcam (Directshow filter). How can I do this?

Any helpful code snippets please?

Answer 1

在 Directshow 中操作帧的一个好习惯是在源过滤器之后添加 SampleGrabber 过滤器。看

SampleGrabber 的目的是操纵帧。
