Hi, re: > has anyone succeeded in using a webcam under freebsd ? > any comments on any webcam and freebsd version ... Yes, I added fixed isochronous support for the ohci usb so that a friend could run "vid" using an OV511-based D-Link DSB-C100 camera. He is hacking around with a webcam as part of his chicken coop and greenhouse controller. I believe he was running one of the 5.x release candidates. I think he has the details at his site where you can usually see his webcam in operation: http://chicks.surfingsc.com/ vid also needs at least one minor hack to comment out a check that just gets in the way, I think this is the needed patch to "vid.c": -/*HACK THE THING +#if 0 +/* HACK */ if(ov511_i2c_read(fd, 0x00) < 0) exit(1); -HACK END*/ +#endif /* set YUV 4:2:0 format, Y channel LPF */ if(ov511_reg_write(fd, OV511_REG_M400, 0x01) < 0) @@ -447,12 +461,16 @@ if(ov511_reg_write(fd, OV511_REG_CE_EN, 0x0) < 0) exit(1); -/* HACK THE THING - * This returns 0 if we have an OV7620 sensor * +#if 0 +/* HACK */ + /* This returns 0 if we have an OV7620 sensor */ if((is20 = ov511_i2c_read(fd, OV7610_REG_COMI)) < 0) exit(1); -HACK END*/ is20 = !is20; +#else + is20 = 0; +#endif + It appears very few webcams have readily available doc. That was what drove the use of the OV511, which may be hard to find. - bruce
