Re: [Bug 1421847] Re: No webcam video input ubuntu 14.04 x86_64

 

Hi,

does it also happen if you use qv4l2?
If yes, please open the device on raw mode (somewhere in the file menu). 
Does it happen now, too?

Thanks,
Gregor

Bug description:
  I tried different webcams on different machines with Ubuntu 14.04 x86,
  x86_64 and Ubuntu 14.10 x86_64.

  This is a BIG trouble : No video on 14.04 x86_64 systems !

  Latest tests :
  Ubuntu 14.04 x86_64
  Lowlatency Kernel and Generic kernel on a second machine.

  lsusb : Bus 003 Device 003: ID 093a:2621 Pixart Imaging, Inc. PAC731x Trust Webcam
  No image on /dev/video0

  vlc : "main demux error: option v4l2-exposure does not exist"
  guvcview : "Could not grab image (select timeout): Resource temporarily unavailable"
  cheese : no output
  skype : nothing

  Same cam pluged on my netbook under Ubuntu x86 : worked out of the box with the same softwares.
  Tried on a Ubuntu 14.10 x86_64 Laptop : perfect

  Two of my customers have the same problem with logitech webcams under
  Ubuntu 14.04 x86_64.

  Any idea ?
  I can't ask them to use normal versions with only 6 months lifetime !
