dve karty BT878

[Jindra Fucik]

No nevyjadril jsem se dost presne.
Takze konkretne - poustim programy z baliku xawtv, nejcasteji pomoci 
programu streamer grabuju obrazky.

No a po nejake dobe zacnou programy psat tohle:

evzen# /usr/local/bin/streamer -q -r 1 -t 3 -o /tmp/ram/strsnap00.ppm 
bktr: sigalrm
bktr: sigalrm
bktr: sigalrm

pak nedokazou spravne zachytit sync obrazu - myslel jsem, ze je problem 
nekde mezi driverem, mainboardem a kartou, (napriklad ze driver neovlada 
ioapic).

Ale jak jsem tak googloval, tak jsem se docetl, ze spis bude problem ve 
zpusobu, jak xawtv realizuje cteni z karty.

V diskuzi na 
(http://lists.freebsd.org/pipermail/freebsd-bugs/2005-May/012969.html) jsem 
nasel vetu:
"Ouch.  When this has happened in the past, it's typically been
because the motherboard and/or video card isn't well supported by
FreeBSD.  Fxtv uses the very old trick of pointing the TV board
output to the memory-mapped linear frame buffer of the video card
"in the application".  Back when it was written there wasn't any
other option.  Now we have Xv and other methods, which are much
better and cleaner for TV apps to use.  Fxtv was just never revised
to use these."
