[FFmpeg-user] DShow and Crossbar support for device name?

[Andrew Blake]

Hi there,

I have a NUUO 7108 - 8 Channel Video Capture Card that I'm trying to stream
into images using image2 over TCP to an application I've built.

The actual streaming over TCP and splitting video to images is fine with a
static file or an AVerMedia TV Capture Card using dshow (1CH)... but I'm
having no luck with this 8 Channel Video Capture card?

I'm assuming that the 8Ch using crossbar? and I don't know how to list the
device name for crossbar devices to try a pin? any ideas?

Two of my attempts below of about a hundred! any help or guidance would be
much appreciated,

Anyone else got a NUUO Capture card working with FFMPEG? (using Windows)

Many thanks,

Andrew
