Well it has been a while since I have messed around with all of this... and it seems that the 'Ben' -series PPC kernel tree is no longer maintained... I am not sure if the Bitkepper PPC kernel tree, or the official tree have code that is working... check here: http://www.ppckernel.org/tree.php?id=5 for the bitkeeper PPC kernel also... I don't have the source code that I used to compile this kernel! i thought that I did somewhere... but it is not on this machine anymore... I will try to get the planb driver working with a more modern kernel and report back here when i have some spare time. also -- i am pretty sure that the planb driver needs the i2c subsystem in order to function. I have used the program 'webcam' to capture images from the video input hardware. here is some configuration information: ----------------------------------------------------------------------- [grab] device = /dev/video0 text = "food? %Y-%m-%d %H:%M:%S" width = 640 height = 480 delay = 60 input = composite norm = ntsc rotate = 0 top = 0 left = 0 bottom = -1 right = -1 quality = 85 trigger = 0 once = 0 ----------------------------------------------------------------------- i usually run webcam like this: webcam webcam.conf here is some sample output: ----------------------------------------------------------------------- [EMAIL PROTECTED]:~/notes$ webcam webcam.conf reading config file: webcam.conf ioctl: VIDIOCSCHAN(0,Composite,flags=0x0,type=2,norm=3): Invalid argument ioctl: VIDIOCMCAPTURE(0,fmt=4,size=48x32): Invalid argument video4linux webcam v1.3 - (c) 1998-2001 Gerd Knorr grabber config: size 640x480 [16 bit YUV 4:2:2 (packed)] input composite, norm ntsc, jpeg quality 85 rotate=0, top=0, left=0, bottom=480, right=640 write config: local transfer /home/httpd/uploading.jpg => /home/httpd/cam.jpg "food? 2005-01-16 19:08:17" ----------------------------------------------------------------------- here is a sample image generated by webcam (no video signal, so it is a black screen...) http://surfdavis.no-ip.com/cam.jpg here is some information from the 8500, with planb module: ------------------------------------------------------------------------- surf:/# modprobe planb surf:/# tail /var/log/messages Jan 16 18:59:15 surf kernel: Linux video capture interface: v1.00 Jan 16 18:59:15 surf kernel: PCI: Enabling device 01:0d.0 (0014 -> 0016) Jan 16 18:59:15 surf kernel: PlanB: PowerMacintosh video input driver rev. 2.11 Jan 16 18:59:15 surf kernel: PlanB: SAA7196 video processor rev. 1 ------------------------------------------------- surf:/# lsmod Module Size Used by Not tainted planb 41124 0 (unused) videodev 5312 2 [planb] dmasound_pmac 69104 0 dmasound_core 13560 0 [dmasound_pmac] soundcore 4520 3 [dmasound_core] i2c-core 14584 0 [dmasound_pmac] -- Dylan Beaudette Soil Science Graduate Group University of California at Davis -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
