hiya,

i have a bktr card in a 3.2/i386 machine. it works, i can use fxtv with it. but what i really need is a command line tool that will record from the card; i'm hoping to hook up the recording to a motion sensor. also, eventually i'll need two cards in the system but it seems that adding another bktr dev to GENERIC should handle this.

so, two questions:
anyone know a cmd line tool to record video from a video-in card?
anyone have success using OpenBSD with two bktr cards?

and no, the application isn't what you think, it's actually for an art installation piece.

D00d, awesome. I've never tried anything like this with OpenBSD. I think your best bet'll be bsdjunkie, he's moving of course right now so it might be a few more days until he can get back up on the board.

actually id love to help, but have never used those types of cards b4 =) I havnt heard of a program offhand for bsd, So i guess the best bet may be to search freshmeat for a linux prog and use linux emulation.

You may have luck with mencoder, part of the mplayer package. It is currently in the FreeBSD ports tree, and has also been ported to Darwin.

I have used it under Linux and Darwin, but not OpenBSD.

i got mencoder to work on NetBSD with the following:
mencoder -tv on:driver=bsdbt848:device=/dev/bktr0:width=320:height=240:norm=NTSC:input=0 -o /data/video/tv.avi -ovc lavc

but the results were dodgy at best - often the encoding would halt after a random number of seconds. a friend of mine got it to work with a similar line under FreeBSD and didnt notice that problem, i believe.

it doesn't work under OpenBSD b/c the bktr driver is different compared to Net/FreeBSD. Doesn't seem like it would be too hard to port; from what i've looked at OpenBSD splits the bktr driver files up whereas Net/Free have them all in one (plus name changes, etc). Maybe some kind soul will port that functionality over.

Someone wrote what i needed. Videod does command line captures from bktr devices in OpenBSD.

I tried it at work on 3.2 with the following:
bktr0 at pci0 dev 10 function 0 "Brooktree BT878" rev 0x11: irq 5
bktr0: Hauppauge WinCast/TV, <no> tuner.
but it didn't work.

Of course all new ports should be used with -current, but instead i tried it at home running 3.3-stable and a:
bktr0 at pci0 dev 8 function 0 "Brooktree BT878" rev 0x11 fun=2900006<MEM,MASTER,CAPLIST,BACK2BACK_STAT,DEVS EL_MEDIUM>pci_mapreg_map: memt 1, memh e7799000, size 1000
bktr0: Warning - card vendor 0x1002 (model 0x0003) unknown.
bktr0: Pinnacle/Miro TV, Temic NTSC tuner.
and this time it worked.

Once i get back to work i'll try the other card on 3.3-stable as well, but i'm happy rigth now that i can get on with the original project.

Oh yeah, i should note that it currently does only still image capturing, not video capturing, though the to-do lists video capture as an eventual goal as well, and i'm a patient man.

Whats a "bktr card"?

[frisco]

Whats a "bktr card"?

A card supported by the bktr(4) driver, which covers a variety of Brooktree chipsets. man bktr on an OpenBSD system for complete info.

They're cheap ($25 on up) and fairly popular.

xawtv was recently ported to OpenBSD as well:

i have it working on a 3.3-stable box, though some apps have some distortion. Don't know whether it's the card's fault or the software's fault, but i'll be testing it on a few more bktr cards i have lying around.
