Title:
zbar: JPEG datastream contains no image
Status in zbar package in Ubuntu:
Fix Released
Bug description:
zbar-0.10 has a problem with its JPEG handling. Specifically, libjpeg
can request that zbar skip forward in its input, but zbar-0.10 does
not implement this callback, instead it returns EOF. This manifests as
certain JPEGs causing the error "JPEG datastream contains no image",
when in fact the JPEG does contain an image.
This was reported upstream [1] and fixed in trunk two years ago [2],
but an updated version of zbar still has not been released. I
contacted the zbar maintainer but got no response.
This patch currently ships with the Homebrew formula on OSX [3], but
Ubuntu users are still encountering this issue [4].
