-v4l-utils
----------
-
-Linux utilities and libraries to handle media devices (TV devices,
-capture devices, radio devices, remote controllers).
-
-You can always find the latest development v4l-utils in the git repo:
-	http://git.linuxtv.org/v4l-utils.git
-
-Those utilities follow the latest Linux Kernel media API, as documented
-at:
-	http://linuxtv.org/downloads/v4l-dvb-apis/
-
-Any questions/remarks/patches can be sent to the linux-media mailinglist.
-See https://linuxtv.org/lists.php for more information about the mailinglist.
-
-There is also a wiki page for the v4l-utils:
-
-	https://linuxtv.org/wiki/index.php/V4l-utils
-
-
---------
-Building
---------
-
-A number of packages is required to fully build v4l-utils. The first
-step is to install those packages. The package names are different on
-each distro.
-
-On Debian and derivated distributions, you need to install the following
-packages with apt-get or aptitude:
-    debhelper dh-autoreconf autotools-dev autoconf-archive doxygen graphviz
-    libasound2-dev libtool libjpeg-dev qtbase5-dev qt5-default
-    libqt5opengl5-dev libudev-dev libx11-dev pkg-config udev make gcc git
-
-
-On Fedora, the package list for a minimal install with dnf or yum is:
-	git automake autoconf libtool make gcc gcc-c++ which perl gettext-devel
-
-(git is only requiried if you're cloning from the main git repository at
- linuxtv.org).
-
-And, to be able to compile it with all usual functionality with qt5,
-you'll need also:
-	alsa-lib-devel doxygen libjpeg-turbo-devel qt5-qtbase-devel
-	libudev-devel mesa-libGLU-devel
-
-The v4l2-tracer also needs the json-c library.
-On Debian: libjson-c-dev; on Fedora: json-c-devel.
-
-After downloading and installing the needed packages, you should run:
-
-	./bootstrap.sh
-	./configure
-	make
-
-If ./configure exit with some errors try:
-
-	autoreconf -i --force
-	./configure
-
-And, to install on your system:
-	sudo make install
-
-Optional features
-^^^^^^^^^^^^^^^^^
-
-Please notice that there's an extra feature to add an extra table to
-decode Japanese DVB tables via iconv. This is meant to be used when
-the iconv itself doesn't come with the ARIB-STD-B24 and EN300-468-TAB00
-tables.
-
-That requires not only the gconv package, but it also needs to be manually
-enabled with:
-	--enable-gconv
-
-----------
-versioning
-----------
-
-The v4l-utils doesn't quite follow the release versioning defined
-at semver.org.
-
-Instead, since version 1.0, it uses:
-
-	MAJOR.MINOR.PATCH
-
-Where:
-
-	MINOR - an odd number means a development version. When
-		the development is closed, we release an even
-		numbered version and start a newer odd version;
-
-	MAJOR - It is incremented when MINOR number starts to be
-		too big. The last change occurred from 0.9.x to 1.0.
-
-	All numbers start with 0.
-
-All versions have their own tags, except for the current
-deveopment version (with uses the master branch at the git tree).
-
-The PATCH meaning actually depends if the version is stable
-or developent.
-
-For even MAJOR.MINOR versions (1.0, 1.2, 1.4, 1.6, ...)
-
-	PATCH is incremented when just bug fixes are added;
-
-For odd MAJOR.MINOR versions (1.1, 1.3, 1.5, 1.7, ...)
-	PATCH is incremented for release candidate versions.
-
-API/ABI stability:
------------------
-
-There should not have any API/ABI changes when PATCH is incremented.
-
-When MAJOR and/or MINOR are incremented, the API/ABI for the
-libraries might change, although we do all the efforts for not
-doing it, except when inevitable.
-
-The TODO files should specify the events that will generate
-API/ABI breaks.
-
----------------
-media libraries
----------------
-
-There are currently three media libraries defined at /lib directory,
-meant to be used internally and by other applications.
-
-libv4l
-------
-
-This library is meant to be used by applications that need to
-talk with V4L2 devices (webcams, analog TV, stream grabbers).
-
-It can be found on the following directories:
-	lib/libv4l1
-	lib/libv4l2
-	lib/libv4l-mplane
-	lib/libv4lconvert
-
-See README.libv4l for more information on libv4l.
-
-The libv4l is released under the GNU Lesser General Public License.
-
-libdvbv5
---------
-
-This library is meant to be used by digital TV applications that
-need to talk with media hardware.
-
-Full documentation is provided via Doxygen. It can be built,
-after configuring the package, with:
-	$ make doxygen-run
-
-It is possible to generate documentation in html, man pages and pdf
-formats.
-
-The documentation is also available via web, at:
-	http://linuxtv.org/docs/libdvbv5/
-
-It can be found on the following directory:
-	lib/libdvbv5
-
-The libdvbv5 is released under GPL version 2.
-
-
-libv4l2rds
-----------
-
-This library provides support for RDS radio applications.
-
-It can be found on the following directory:
-	lib/libv4l2rds
-
-The libv4l is released under the GNU Lesser General Public License.
-
----------
-Utilities
----------
-
-The utilities are stored under /util directory.
-
-The (for now for v4l-utils private use only) libv4l2util library is
-released under the GNU Lesser General Public License, all other code is
-released under the GNU General Public License.
-
-v4l-utils includes the following utilities:
-
-decode_tm6000:
-Decodes tm6000 proprietary format streams.
-Installed by make install under <prefix>/bin.
-
-ir-keytable:
-Dump, Load or Modify ir receiver input tables.
-The ir tables for remotes which are known by the kernel
-(and loaded by default depending on dvb card type) can be found
-under utils/keytable/keycodes.
-v4l-keytable does not get installed by make install.
-
-ir-ctl:
-A swiss-knife tool to handle raw IR and to set lirc options
-
-qv4l2:
-QT v4l2 control panel application.
-Installed by make install under <prefix>/bin.
-
-rds-saa6588:
-Poll i2c RDS receiver [Philips saa6588].
-rds-saa6588 does not get installed by make install.
-
-v4l2-compliance:
-Tool to test v4l2 API compliance of drivers.
-Installed by make install under <prefix>/bin.
-
-v4l2-ctl:
-Tool to control v4l2 controls from the cmdline.
-Installed by make install under <prefix>/bin.
-
-v4l2-dbg:
-Tool to directly get and set registers of v4l2 devices,
-this requires a kernel >= 2.6.29 with the ADV_DEBUG option
-enabled. This tool can only be used by root and is meant
-for development purposes only!
-Installed by make install under <prefix>/sbin.
-
-v4l2-sysfs-path:
-FIXME add description.
-Installed by make install under <prefix>/bin.
-
-v4l2-tracer:
-Tool to trace, record and replay userspace applications
-that implement the v4l2 memory-to-memory stateless video
-decoder interface.
-Installed by 'make install' under <prefix>/bin.
-
-xc3028-firmware:
-Xceive XC2028/3028 tuner module firmware manipulation tool.
-xc3028-firmware does not get installed by make install.
-
--------------------
-Syncing with Kernel
--------------------
-
-There are a number of files on this package that depends on the Linux Kernel.
-
-In order to make easier to keep it in sync, there's a target on this
-package to do the synchronism.
-
-For the sync to work, you need to run it on with 64 bits userspace and
-be sure that glibc has the development package for 32 bits.
-
-For Fedora, this is provided via this package: glibc-devel.i686
-
-There are some steps required:
-
-step 1) at the Kernel git tree:
-
-We need to sanitize the headers to be installed. To do that, you should
-run
-
-	$ make headers_install INSTALL_HDR_PATH=usr/
-
-This will create the dir "usr/" inside the Kernel tree.
-
-step 2)
-
-Be sure that you have installed both glibc development packages for
-32 and 64 bits, as otherwise the next step will fail.
-
-step 3) at v4l-utils tree:
-
-	$ ./sync-with-kernel.sh location/of/the/kernel/tree
-
-Alternatively, steps 1 to 3 can be replaced with:
-
-KERNEL_DIR=location/of/the/kernel/tree && (cd $KERNEL_DIR && make headers_install INSTALL_HDR_PATH=usr/) && ./sync-with-kernel.sh $KERNEL_DIR
-
-step 4)
-
-Remove the usr/ from the Kernel tree.
