Watching TV with DragonFly

[Stefan 'Steve' Tell]

Hi Guys,

I want to watch TV with my Hauppauge WinTV/PCI (bt848) on my
DragonFlyBSD-box. 

The card works:

bktr0: <BrookTree 848A> mem 0xdff00000-0xdff00fff irq 11 at device 9.0 on
pci0
bktr0: Hauppauge Model 60124 C1V
bktr0: Detected a MSP3400C-C6 at 0x80
bktr0: Hauppauge WinCast/TV, Philips FR1216 PAL FM tuner, msp3400c stereo.

I can watch TV with xawtv using grabdisplay (with overlay-mode I only got a
black screen). My favorite TV-application on BSD is mplayer, but I can't
get it working on DragonFly:

Playing tv://.
TV file format detected.
No such driver: bsdbt848

Any hints how to build mplayer with DragonFly-Support?

Thanks in advance.
