I think both the opal and h323plus community can benefit. http://www.h323plus.org/source/download/ffmpeg_x264.zip Place all files in your application directory. The FFMPEG (with w32threads) and X264 is built with mingw/msys. x264plugin_helper.exe is built with vs2008 and requires vs2008 runtime.

I have to admit to not being able to get the H.263 (or x264) codecs to compile and work under Windows, though I have only tried somewhat briefly. Unfortunately the authors of all the libraries mainly use Linux, though it is my understanding that it can be compiled using MinGW/Cygwin. I am sure the OPAL community would be incredibly grateful to anyone that can provide a pre-built binary for the H.263 (and x264!) codec. -------- Robert Jongbloed Vox Lucida Pty. Ltd.
