End-users should use the installers provided in the binary release. That is one of the benefits of a binary distribution, after all...
AVbin is a C library following standard conventions.
Clone the git repository:
git clone https://github.com/AVbin/AVbin.git avbin
See the header file include/avbin.h
and the online API documentation at
http://avbin.github.com/AVbin/Docs.html
If you are interested in testing, contributing code, or otherwise helping out, we encourage you to join the Pyglet mailing list (AVbin was originally created for the Pyglet project). See http://pyglet.org/contribute.html
AVbin is designed to be used with a particular version of Libav. This version
of Libav is included as a git submodule of the AVbin project under the libav
directory. Note that this version of Libav may contain AVbin-specific patches,
though we try to get all patches accepted upstream.
Use the included build.sh
script to compile AVbin. This takes care of
configuring Libav correctly, compiling it, then linking it with the AVbin
sources. The final AVbin libraries are placed in the dist
directory.
To build on your platform, use the included build.sh
script. See
build.sh --help
for usage information.
If you are planning on distributing the self-built binary to anyone other than
yourself, please create a PRERELEASE
file in the root of the project directory
containing a version modifier such as -my-version
.
get_avbin_info()->version_string
would then return 10-my-version
for a custom
build of AVbin 10, while get_avbin_info()->version
will still return the integer
10
.

./build.sh [desired options and targets]
AVbin is currently known to function on the following platforms
-
Linux x86 (32- and 64-bit)
-
Mac OS X 10.6 - 10.8 (32- and 64-bit)
-
Windows XP (32-bit)
-
Windows 7 (64-bit)
-
Using the same value for
platform
as the build you just did, run:./dist.sh [platform]
-
Install Doxygen from http://www.stack.nl/~dimitri/doxygen/
-
Open/Edit
Doxyfile
to your liking and generate it with Doxygen. The GUI frontend seems to work just fine.
Run the binary installer, or place the resulting avbin.so
, avbin.dylib
or
avbin.dll
from the dist
directory into the appropriate system directory.
The AVbin dynamic library exports all of Libav's functions from libavcodec
,
libavutil
, libavformat
, and libswscale
. It also exports some higher-level
functions which have a fixed ABI (they will not change in incompatible ways
in future releases), documented in include/avbin.h
.
Due to the linkage between AVbin and Libav, AVbin must be licensed under the LGPL or GPL. Currently all GPL features of the Libav configuration are disabled, and AVbin is licensed under the LGPL.
You should see the accompanying COPYING.LESSER file for details. In summary, you must note the usage of AVbin within the documentation of your application. If you make changes to either library, you must either contribute said changes upstream or include the sources of these changes within your distributed application.
