I have a VGA to USB capture device -an Epiphan VGA2USB - that I've finally starting using with my Youtube channel. On the Epiphan website under Linux support it says it has the drivers for most of the major kernels and it works with V4L (Video 4 Linux) programs with the loopback module. I know I had to fiddle and fuss with it to get it going but I finally got it working on a spare machine. It works... okay I guess - better than shooting the screen with my cellphone camera. VLC is my capture software.

I've moved most of my computer experiments out of the living room - where I can have natural light and it's warm - down into the basement. I definitely could use more light but there's not much I can do about the heat - it's a little chilly down there right now.

I wanted to free up the capture computer and use a different system for capturing the output of my test computers. I got the 'new' capture computer updated, drivers installed, plugged in the Epiphan... and I got no capture. VLC doesn't see it.

*&^#@!

After spending perhaps an hour reinstall drivers, extra programs and utilities without success I double checked the website: yep, it says Linux support with V4L supported programs with the V4L loopback module.

Wait... did I install the V4L loopback module?

*head desk* I'm an idiot.

I installed the loopback module and boom! Up it comes! If I remembered that and hour ago I would have saved myself a lot of time and effort. And a bit of shivering.

There may be an upside to all this time I spend shivering in the basement. I've installed a few V4L utilities so maybe I can tweak the capture device using software. Something is goofy with the capture device and some of my video programs will not render the video *at all*. My video editor is fine with the capture so I'm not terribly concerned - but if I can tweak things it might make my life a little easier.

Possibly warmer too.

Heh, get a couple more Pentium machines down there.. nothing like Intel's best room-heater-on-a-chip for warming up a space..
