Good Lord Murphy's working overtime. It's not the timing I would have chosen. Anyway.

Not the cleanest code in the world, and as H-P mentioned, MyFirstDriver(tm). It does not adhere to either V4L2 or DVB, because V4L2 is in flux and I've only briefly looked at DVB. I'm not sure where the better fit is. I wanted to get the basics of capturing the MPEG stream down first before I worried about getting the capture framework correct at the same time. I think the card *can* do YUV capture, but I haven't explored it.

This is the model I've been trying to maintain, but without as much separation as I'd like. Regardless, the following link contains the fruits of my efforts to date: http://www.projectplasma.com/PVR/ Please don't slashdot it ;) Michael Hieb wrote: > Obviously I have been a dunce and bought the wrong card. I wouldn't go that far. Other than kfir based cards which, other than the Hauppauge PVR-PCI, are hard to come by, what hardware encoders have a Linux driver Open or Closed?

This acquisition occured in the middle of 2002, so their still getting settled in. and earlier: > For all I know the "leaked" ... drivers are put there as a proof of > concept to lure suckers like me into writing a Linux driver for > the 350 and 250. :-} Nice try ;) The leak caused a lot of embarrasment and trouble for the party at fault. That said, unless you're trully desparate, I urge people to not pursue those drivers: it has its own incompatible API and it eats at least four majors regardless who they're assigned to. If you need to get them working, I posted a method in SHS's forums http://www.shspvr.com/forum/viewtopic.php?t=1378 (warning: NTSC specific). Other people have gotten PAL and SVideo working. I think some people need help with SECAM. John (aka PlasmaJohn)
