Hi All,
I'm afraid version 0.3.3 had a nasty bug, so here is 0.3.4:
http://people.atrpms.net/~hdegoede/libv4l-0.3.4.tar.gz
This release has the following changes:
libv4l-0.3.4 (the brownpaperbag release)
----------------------------------------
* The mmap64 support in 0.3.3, has caused a bug in libv4l1 when running on
32 bit systems (who uses those now a days?), this bug caused v4l1
compatibility to not work at all, this release fixes this
* Some apps (xawtv, kopete) use an ioctl wrapper internally for various
reasons. This wrappers request argument is an int, but the real ioctl's
request argument is an unsigned long. Passing the VIDIOC_xxx defines through
to the wrapper, and then to the real ioctl, causes the request to get sign
extended on 64 bit args. The kernel seems to ignore the upper 32 bits,
causing the sign extension to not make a difference. libv4l now also
ignores the upper 32 bits of the libv4lx_ioctl request argument on 64 bit
archs
* Add a bugfix patch for kopete in the appl-patches dir, currently it assumes
that it got the width and height it asked for when doing a S_FMT, which is a
wrong assumption
Regards,
Hans
