Can you capture video with DirectShow ? This works normally for windows (only). Testing can be done with the GrapphEdit(64) or GraphStudioNext(64). For both gives 32 and 64 bit Versions.

If this works, you can deal with freepascal and the LazarusVideoUtilities

For using HDMI you must have a FrameGrabber to handle the HDMI signal. On a PC it is only output, no input possible.

I don't know how to do it but maybe I can help make your question a little more clear*: You mean that your capture devices, however they are connected to the computer, do have HDMI and composite inputs and what you want is to select the HDMI ones. Is that it?

they have inputs hdmi and composite, and they're connected by USB to the computer but I can't see digital signal, only analogic signal with the attachment src, instead the webcam signal if I see it. thanks for all replies.
