Motion help please (Motion only supports mmap) ??
Hi I'm trying to get Motion to work with my Webcam and hope someone can help.
I'm using Ububntu 8.10 with a webcam Logitech Quickcam Chat. I have used EasyCam to install the driver and tested it with Cheese Webcam Booth. I then Installed Motion through Synaptic. When I try to start Motion I get the below. [0] Processing thread 0 - config file /etc/motion/motion.conf [0] Motion 3.2.9 Started [0] ffmpeg LIBAVCODEC_BUILD 3355136 LIBAVFORMAT_BUILD 3409664 [0] Thread 1 is from /etc/motion/motion.conf [1] Thread 1 started [1] cap.driver: "ivtv" [1] cap.card: "Hauppauge WinTV PVR-150" [1] cap.bus_info: "0000:02:09.0" [1] cap.capabilities=0x01070051 [1] - VIDEO_CAPTURE [1] - VBI_CAPTURE [1] - TUNER [1] - AUDIO [1] - READWRITE [0] motion-httpd/3.2.9 running, accepting connections [0] motion-httpd: waiting for data on port TCP 8080 [1] Supported palettes: [1] 0: HM12 (HM12 (YUV 4:2:0)) [1] 1: MPEG (MPEG) [1] Unable to find a compatible palette format. [1] ioctl(VIDIOCGMBUF) - Error device does not support memory map [1] V4L capturing using read is deprecated! [1] Motion only supports mmap. [1] Capture error calling vid_start [1] Thread finishing... Could someone help me to sort this out with Motion if not is there another motion detector I could use. Thanks in advance Rae |
Fixes the error
Found this on another site. Try preloading v4l2convert.so:
LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so motion -n I'm posting here because this page came up on top of the google search I did... |
motion runs all the time
you wont be able to start any thing to do with the cam till you turn it off wxcam has motion i think its a nice program read and install all the page tell you to http://wxcam.sourceforge.net/ hope that helps |

Sorry to bump this old thread, but i have the exact same error with 1 of my webcams.
Where am i supposed to add the line "LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so motion -n"? I'm running Debian. Thanks in advance... |
