Hi- I have a ubuntu 11.04 machine that I'm trying to capture 12 usb webcam feeds on. The webcams are split over 3 pcie usb cards and the motherboards's usb controller. I'm encountering instability using both streamer and guvcview. I can get all 12 streams running but eventually one dies (in a minute or so) and then about 3 more die as well...leaving me with 7 or 8 stable streams. What is the limitation? The guvcview error is:
Could not grab image (select timeout): Resource temporarily unavailable which is repeated repeatedly.... the streamer error is: v4l2: oops: select timeouts this usually only effects one or two cameras with both programs dmesg yields: [ 5330.048166] uvcvideo: Failed to resubmit video URB (-27). [ 5330.048174] uvcvideo: Failed to resubmit video URB (-27). [ 5330.048178] uvcvideo: Failed to resubmit video URB (-27). [ 5330.048183] uvcvideo: Failed to resubmit video URB (-27). [ 5330.048188] uvcvideo: Failed to resubmit video URB (-27). I only need to capture an image from every camera every 2.4 seconds, if someone can provide me a good work-around I'd appreciate it! -cheers jason -- /* Jason Pitt PhD 206.667.5603 Roth Lab jp...@fhcrc.org Basic Sciences Division Fred Hutchinson Cancer Research Center 1100 Fairview Ave N A3-135 Seattle, WA 98109 */ _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
