libam7xxx uses the linux kernel coding style:
http://kernel.org/doc/Documentation/CodingStyle
+=== Getting and compiling libam7xxx
+
+libam7xxx depends on 'libusb-1.0' and optionally on 'libav' or 'ffmpeg' for
+its example programs, the build system used is 'cmake'.
+
+On a Debian based system, the dependencies can be installed with this command:
+
+ $ sudo aptitude install cmake \
+ libusb-1.0-0-dev \
+ libavformat-dev \
+ libavcodec-dev \
+ libavdevice-dev \
+ libswscale-dev
+
+With libav/ffmpeg version previous than 0.9 this patch is needed:
+http://git.ao2.it/libam7xxx.git/blob_plain/refs/heads/debian:/debian/patches/0002-Revert-am7xxx-play-switch-to-avcodec_encode_video2.patch
+
+The library and the example programs can be compiled following these steps:
+
+ $ git clone git://git.ao2.it/libam7xxx.git
+ $ cd libam7xxx
+ $ mkdir build
+ $ cd build
+ $ cmake ../
+ $ make
+
+After that the example programs can be found in the +bin/+ subdirectory.
+
=== Debug builds
The suggested way to hack on the project is:
$ cd build
$ wget -nv http://sourceforge.net/projects/libusbx/files/releases/1.0.11/Windows/libusbx-1.0.11-win.7z
$ 7z -olibusbx-1.0.11-win x libusbx-1.0.11-win.7z
+ $ wget -nv http://win32.libav.org/win32/libav-win32-20120521.7z
+ $ 7z x libav-win32-20120521.7z
