The x264 library is only the H.264 encoder, the decoder is in FFmpeg. Note that this is GPL and is not compatible with the MPL license of PTLib/OPAL. As a work around a GPL application "x264plugin_helper" was created and OPAL talks to it via a socket. While in breach of the spirit of GPL, it is legal. And don't get us started on licensing issues ... Changed lines 18-21 from:

The [[http://ffmpeg.mplayerhq.hu | FFmpeg]] library is used by several of the OPAL video plugin codecs. The history of FFmpeg is long and torturous, and there are many API breaks along the way. That said it is the best game in town for performance and interoperability. !!Building and installing FFmpeg on Linux FFmpeg and x264 are usually available as packages in the distribution. Installing the package and running OPAL configure is usually sufficient. It will be detected and compiled as required. The exact name of the package varies depending on the distribution. For example, on Red Hat it is "sudo yum install ffmpeg-devel x264-devel". !!Building and installing FFmpeg on Windows Most importantly, don't try to compile FFMpeg for Windows unless you enjoy pain. Seriously. Many have tried and failed.

FFmpeg can only be built on Windows using the Msys+MingW toolchain. The [[http://ffmpeg.arrozcru.org/wiki/index.php?title=Main_Page|FFMpeg on Windows Wiki]] gives detailed instructions on how to do this. '''IMPORTANT''': You will need to add "c:\msys" to the VSNET2005_PWLIB_CONFIGURE_EXCLUDE_DIRS environment variable to avoid Opal configure from attempting to use the new header files. '''Note 1''': If you experience a "hang" while running the "./configure" for FFmpeg, try opening the Task Manager and killing the "lvprcsrv.exe" process. This is apparently a known issue when compiling with the MingW toolchain. '''Note 2''': If the compile fails with errors relating to "vfw", add the "--disable-devices" option when confguring FFmpeg Changed lines 4-8 from:

!!Building and installing FFmpeg on Linux 1. Check to see if your system has the correct version of FFmpeg installed using the pkg-config program: $ pkg-config --modversion libavcodec libavformat libavdevice libavutil 51.71.0 52.22.1 52.1.0 49.10.0 If the version numbers differ, we strongly suggest you uninstall FFmpeg and install the recommended version as described below. If pkg-config does not know about FFmpeg, check for the existence of the following files - probably in /usr/local/lib: libavcodec.so libavformat.so libavdevice.so libavutil.so Remove these files if they exist. Also check for the existence of the following include directories - probably in /usr/local/include libavcodec libavformat libavdevice libavutil Remove these directories (and their contents) if they exist 2. Extract the recommended revision of FFmpeg using the Subversion command below, or download this [[http://files.opalvoip.org/bin/ffmpeg-v15261.tar.gz | tarball ]] svn checkout -r15261 svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg 3. Configure and build the shared library version of FFmpeg. cd ffmpeg ./configure --enable-shared make '''NOTE:''' it may be necessary to add options depending on the architecture of the system. For example, it has been found that some Intel Core Duo systems require --disable-mmx to prevent a crash in the H.263 codec at run-time. 4. Install FFmpeg. The default install location is /usr/local - if you want to use a different location then you will need to use different configure options. sudo make install 5. Add the directory /usr/local/lib/pkgconfig to the search path for pkg-config. Without this, Opal will not be able to locate FFmpeg when running configure. This is usually done by setting the PKG_CONFIG_PATH environment variable For bash/sh export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig For tcsh/csh setenv PKG_CONFIG_PATH /usr/local/lib/pkgconfig Test this by running the pkg-config command described in step 1 above. 6. Add the directory /usr/local/lib to both the LD_LIBRARY_PATH and PTLIBPLUGINDIR environment variables. Without this, Opal will not be able to locate the libavcodec.so file and it's dependencies at run time. For bash/sh export LD_LIBRARY_PATH=/usr/local/lib export PTLIBPLUGINDIR=/usr/local/lib For tcsh/csh setenv LD_LIBRARY_PATH /usr/local/lib setenv PTLIBPLUGINDIR /usr/local/lib 7. Configure Opal. For the release version ./configure For the debug version ./configure --enable-debug The status of the codecs will be displayed at the end of the configure process.
