The capture filter typically has two or more output pins, and they output the same type of media, such as previewing the pin and capturing the pin, so the pins cannot be distinguished according to the media type. Each pin is differentiated according to the function of the pin, and each pin has a GUID, called the pin type.If you want to get a closer look at the type of pin, see the related content working with pin Categories.

Preface
Over the past few days, I have been eager to write server programs. All series of articles have been updated slowly. Sorry :)
Note:
This series of articles is limited to learning and communication and focus on the process. Due to the involvement of companies, source code download is not provided. Sorry !! But please rest assured that I will post the core, implementation, and other codes that can be pasted out, and strive to answer every question in the message as much as possible. Thank

The idea of remote screen capture is very simple, that is, direct access to the device's video memory data, reproduced by the PC screen. Since we have implemented the Custom channel, we can complete the data acquisition by adding a custom_command_screenshots command on the basis of the original program. But what's more
