I have a BT848, which is very outdated, but i've got my niftyness quotent out of it by doing wacky video molestation stuff for parties, and other various teleconferencing stuff. > Might be nice if it works in Linux too, but doesn't _have to_ > I was also wondering what res people are using it at and if mpeg4 would be a > good choice for encoding TV programmes to disk ;P It really depends on what you're sampling. If you're sampling free-to-air analogue PAL, then capturing at any more than PAL resolution is pretty worthless. If you're grabbing digital TV though, thats another matter. > So far I only know of the Leadtek WinFast 2000 card. I'm not up on the current cards, but go for something that has MPEG encoding onboard. That way your CPU won't get all loaded up with it. MPEG-4 is great, but won't play on a DVD player. Most DVD players these days will play SVCD (MPEG-2) or VCD (MPEG-1). MPEG-4 however is much better compression.

I'm not sure which system was relevant to the UCC, but there was a 16 bit user ID field which could be used to map to a TLA. Generally speaking, I don't think interoperability was high on the priorities of the people using that sort of scheme, so you can pick any character set you want. ::-) http://www.byte.com/art/9612/sec4/art4.htm The character set above lists: $.0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ Nick. -- Nick Bannon | "I made this letter longer than usual because nick-sig@rcpt.to | I lack the time to make it shorter." - Pascal From nick at ucc.gu.uwa.edu.au Mon Mar 15 23:43:40 2004 From: nick at ucc.gu.uwa.edu.au (Nick Bannon) Date: Wed Oct 27 01:28:38 2004 Subject: [tech] tv tuner card In-Reply-To: <20040315130900.GA30328@shikita.rcpt.to> References: <20040315115655.GA186084@morwong.ucc.gu.uwa.edu.au> <20040315130900.GA30328@shikita.rcpt.to> Message-ID: <20040315154340.GF423999@morwong.ucc.gu.uwa.edu.au> On Mon, Mar 15, 2004 at 09:09:00PM +0800, David Basden wrote: > On Mon, Mar 15, 2004 at 07:56:55PM +0800, Paul Marinceu wrote: [...] > > Might be nice if it works in Linux too, but doesn't _have to_ Pah, of course they work with Linux. It's what they use for embedded media appliances. As a marketing stunt, one HDTV vendor even sells a card that _only_ works with Linux. ::-) [...] > I'm not up on the current cards, but go for something that has MPEG > encoding onboard.

Most DVD players these Some will, Strathfield has a $179 and a $249 DVD player that will play MPEG-4 (though perhaps not all the variations on MPEG-4).

I've found in general the problem is with false negatives, not false positives, so negative scores don't make much difference (except allowing a way for mail to get through sometimes). If anyone's seeing many false postives, let me know.

The mtimes update fine, and the atimes update fine locally on morwong (looking with ls -l and ls -lu). Has anyone seen this before, or got suggestions on sorting it out?

A script tells me if a file* in my public-html directory had been updated (by procmail) more recently than it has been accessed. For many months (maybe up to a year?) the atime has not changed whenever I access the file via HTTP. * This file is my spam list. I use procmail and a script to merge the URLs from the SpamCop "browse to this URL to report this spam" messages into the list. The first level (forwarding spam to my spamcop.net reporting address) is also handled through procmail. Because SpamAssassin user configs are turned off (therefore no whitelisting, custom scoring or Bayesian filtering is done) I do manual whitelisting and homebrew spam tests with procmail. -- ... File not found. Should I fake it?
