Easycap is not really a brand. They describe the hardware here a bit.

Device Manager (Right Click win Start), then Properties, then Details, in menu select "Hardware Ids"
Try and match the hexadecimal numbers, like the EB1A:2861 part listed there in Device Manager.
The idea is, to get some idea which Easycap you've got, may make
finding software easier.
The video capture market kinda collapsed before COVID, and
some of the chips are no longer made. Cheesy chips have been
made to replace them. It was never easy finding software
for these things -- this is why when purchasing, you read
the Amazon reviews and see if the owners say "the software
was crap but I found that XXX worked". The hardware is not
worth buying, unless there is an identifiable software package
to use.
If you were more of a digital guy... Well.... :-)

To give an example of the misery, I have a TV tuner card (which
has capture on the front end), and even the Linux DVD won't
run it out of the box. So I added a firmware file to the DVD, and
that DVD exists purely for running the hardware in question.
See, that's how nasty the digital world is for ya. Look at
the extra work you get to do.
