[Bug 1385152] Re: jpgl support in libv4lconvert is missing

 

You're preloading the wrong library. The following two are made for preload:
/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so
/usr/lib/x86_64-linux-gnu/libv4l/v4l2convert.so

V4L1 applications need v4l1compat.so, newer and V4L2 compatible ones
need v4l2convert.so

** Changed in: v4l-utils (Ubuntu)
       Status: New => Invalid

Title:
  jpgl support in libv4lconvert is missing

Status in “v4l-utils” package in Ubuntu:
  Invalid

Bug description:
  Seems support for the jpgl palette has been around in v4lconvert since 2011 or so, but is not present in the ubuntu version.
  Is there an easy way I can add that so I can get my old webcam working on ubuntu?
  I'm trying to use the cam with either"motion" or "fswebcam".  

  I tried this on an up to date 14.04LTS:
  # v4l2-ctl --list-formats-ext
  ioctl: VIDIOC_ENUM_FMT
  	Index       : 0
  	Type        : Video Capture
  	Pixel Format: 'JPGL' (compressed)
  	Name        : JPGL
  		Size: Discrete 320x240
  		Size: Discrete 640x480

  # LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4lconvert.so.0.0.0 fswebcam
  --- Opening /dev/video0...
  Trying source module v4l2...
  /dev/video0 opened.
  No input was specified, using the first.
  Unable to find a compatible palette format.
