2008-07-03v4l2-library: libv4l: update mercurial tree to latest 0.3.1 releaseThierry MERLE
From: Hans de Goede <j.w.r.degoede@hhs.nl> This patch syncs (updates) the libv4l in mercurial with (to) the latest 0.3.1 release. - Only serialize V4L2_BUF_TYPE_VIDEO_CAPTURE type ioctls - Do not return an uninitialized variable as result code for GPICT (fixes vlc, but see below) - Add an apps-patches directory which includes: * vlc-0.8.6-libv4l1.patch, modify vlc's v4l1 plugin to directly call into libv4l1, in the end we want all apps todo this as its better then LD_PRELOAD tricks, but for vlc this is needed as vlc's plugin system causes LD_PRELOAD to not work on symbols in the plugins * camorama-0.19-fixes.patch, small bugfixes to camorama's v4l1 support, this patch only fixes _real_ bugs in camorama and does not change it to work with v4l1compat. Although it does work better with these bugs fixed :) With this patch and LD_PRELOAD=<path>/v4l1compat.so it works flawless.

2008-07-01v4l2-library: libv4l2 and v4l2convertThierry MERLE
From: Hans de Goede <j.w.r.degoede at hhs.nl> libv4l2 offers v4l2_ prefixed versions of open/close/etc. The API is 100% the same as directly opening /dev/videoX using regular open/close/etc, the big difference is that format conversion is done if necessary when capturing. That is if you (try to) set a capture format which is not supported by the cam, but is supported by libv4lconvert, then the try_fmt / set_fmt will succeed as if the cam supports the format and on dqbuf / read the data will be converted for you and returned in the request format. v4l2convert: open/close/ioctl/mmap/munmap library call wrapper doing format conversion for v4l2 applications which want to be able to simply capture bgr24 / yuv420 from v4l2 devices with more exotic frame formats.
