I have written a video capture program which uses the syncronous capture mode on a BT848 card. I called it "videocat", and its was originaly developed with FreeBSD 3.3, and everything was more or less happy. Unfortunately when I upgraded to FreeBSD 4.1-Stable, it broke. My hardware is: bktr0: <BrookTree 878> mem 0xfebfe000-0xfebfefff irq 16 at device 16.0 on pci0 iicbb0: <I2C generic bit-banging driver> on bti2c0 iicbus0: <Philips I2C bus> on iicbb0 master-only smbus0: <System Management Bus> on bti2c0 bktr0: Hauppauge Model 61291 D110 bktr0: Hauppauge WinCast/TV, Philips NTSC tuner, remote control. The problem is: bktr dosn't seem to send the per-frame signal when I have it set to just give me one field of the video. (I'm digitizing at 1/4 screen resolution, so I only want one field). When I tell it to get both fields, then the signal is delivered. Unfortunately when its in both-fields mode and I ask for 352x240 (or 320x240) it only gives me about 3/4 of the image, stretched verticaly. When I ask for 640x480 the signal is again not delivered. fxtv, and another program I wrote which is similar to fxtv, work fine. But then they use the "gimmie a frame now" API, not the syncronous one. They also use RGB format, while videocat uses YUV-422. I've stared at the bktr sourcecode, with no luck... Am I missing something obvious? Please Help... My program can be found at http://www.bobdbob.com/~protius/software/video.tgz. Its pretty much a BSD license, if anyone actualy wants to use it. -Tommy "Are you alright?"
