Re: [Xpert]Tearing, with regard to viewing DVDs (Trident Ai1)
This is really stretching the bounds of 'on topic', but just this once... :) Kenneth Wayne Culver ([EMAIL PROTECTED]): Is the code in this de-interlacing player portable??? meaning will it work in FreeBSD? The algorithms are portable. The capture API I use is 'video4linux' which afaict has nothing linux specific about it, and I would hope it would be supported under FreeBSD, but I have no clue. -Billy On Wed, 19 Dec 2001, Billy Biggs wrote: Mark Vojkovich ([EMAIL PROTECTED]): The Wedding Singer and Dark City are good ones. There is also a good vob trailer for Lost in Space on the web someplace. Of course, good is relative. They're not DVD quality because they're all interlaced. That said, many DVDs are interlaced, for example on a large percentage of NTSC DVDs you will see sections of the disc with the 3:2 pulldown sequence expanded, and as such require deinterlacing. My technical discussion on DVD deinterlacing: http://www.dumbterm.net/graphics/dvd/ My DVD player source with realtime deinterlacing and 3:2 pulldown removal: http://www.sf.net/projects/movietime/ Not to mention all the DVDs of TV shows which are natively interlaced, unlike the film-source examples mentioned above. ObOnTopic: One way to test for tearing if you have a v4l card would be to try out my TV deinterlacer, which will output at 59.94fps (or 50fps for PAL). You'll see tearing pretty quick if your driver doesn't double buffer: http://www.dumbterm.net/graphics/tvtime/ -- Billy Biggs [EMAIL PROTECTED] ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert

I'm using the latest CVS release on my Toshiba Satellite 1805-S204. It has the Trident CyberBlade Ai1 chipset. Is the apparent tearing an issue with the driver in the CVS release or possibly the software? Although this isn't in response to the SiS630 driver, I thought it was a relevant question. It's usually a driver issue. Mark.
