A new version of libv4l is out. Simply copying the libv4l-0.5.8 ebuild works. I tested the library with a gscpa and a uvc webcam; seems to work perfectly. The changelog: libv4l-0.6.0 ------------ * Recognize disabled controls and replace with fake equivalents where available * Add support for decompressing ov511 and ov518 "JPEG", by piping data through an external helper as I've failed to contact Mark W. McClelland to get permission to relicense the code. If you know a working email address for Mark W. McClelland, please let me know. * Add tons of laptop models to the upside down devices table * Support for rgb565 source format by Mauro Carvalho Chehab * Many bug fixes (see the mercurial tree for details) * Improved pac207 decompression code to also support higher compression modes of the pac207, which enables us to use higher framerates. Many many thanks to Bertrik Sikken for figuring the decompression out! libv4l-0.5.99 ------------- * Link libv4lconvert with -lm for powf by Gregor Jasny * Fix black screen on devices with hardware gamma control * Fix crash with devices on which we do not emulate fake controls * Add a patch by Hans Petter Selasky <hselasky@freebsd.org>, which should lead to allowing use of libv4l (and the Linux webcam drivers ported to userspace usb drivers) on FreeBSD, this is a work in progress libv4l-0.5.98 ------------- * Add software gamma correction * Add software auto gain / exposure * Add support for separate vflipping and hflipping * Add fake controls controlling the software h- and v-flipping * Add ability to determine upside down cams based on DMI info * Add the capability to provide 320x240 to apps if the cam can only do 320x232 (some zc3xx cams) by adding black borders * Rewrite video processing code to make it easier to add more video filters (and with little extra processing cost). As part of this the normalize filter has been removed as it wasn't functioning satisfactory anyways * Support V4L2_CTRL_FLAG_NEXT_CTRL for fake controls by Adam Baker * Some makefile improvements by Gregor Jasny * Various small bugfixes and tweaks * The V4L2_ENABLE_ENUM_FMT_EMULATION v4l2_fd_open flag is obsolete, libv4l2 now *always* reports emulated formats through the ENUM_FMT ioctl libv4l-0.5.97 ------------- * As the version number shows this is a beta release of the 0.6.x series, the big change here is the addition of video processing to libv4l currently this only does whitebalance and normalizing (which turns out to be useless for most cams) but the basic framework for doing video processing, and being able to control it through fake v4l2 controls using for example v4l2ucp is there. The initial version of this code was written by 3 of my computer science students: Elmar Kleijn, Sjoerd Piepenbrink and Radjnies Bhansingh * Currently whitebalancing gets enabled based on USB-ID's and it only gets enabled for Pixart webcam's. You can force it being enabled with other webcams by setting the environment variable LIBV4LCONTROL_CONTROLS, this sets a bitmask enabling certain v4l2 controls which control the video processing set it to 15 to enable both whitebalancing and normalize. You can then change the settings using a v4l2 control panel like v4l2ucp * Only report / allow supported destination formats in enum_fmt / try_fmt / g_fmt / s_fmt when processing, rotating or flipping. * Some applications / libs (*cough* gstreamer *cough*) will not work correctly with planar YUV formats when the width is not a multiple of 8, so crop widths which are not a multiple of 8 to the nearest multiple of 8 when converting to planar YUV * Add dependency generation to libv4l by: Gilles Gigan <gilles.gigan@gmail.com> * Add support to use orientation from VIDIOC_ENUMINPUT by: Adam Baker <linux@baker-net.org.uk> * sn9c20x cams have occasional bad jpeg frames, drop these to avoid the flickering effect they cause, by: Brian Johnson <brijohn@gmail.com> * adjust libv4l's upside down cam detection to also work with devices which have the usb interface as parent instead of the usb device * fix libv4l upside down detection for the new v4l minor numbering scheme * fix reading outside of the source memory when doing yuv420->rgb conversion
bumped, thanks
