I think both the opal and h323plus community can benefit.

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.

The answer to your questions are:

1) Yes, but you need to compile it.

2) The result of compiling it is a DLL

3) You will have to figure out why it doesn't compile under windows.

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.

Hi robert.

Many thanks for your last support; I need to use OpenPhone3.8.2 by H.263 codec run.

1) Is OpenPhone 3.8.2 with Opal 3.8.2 & Ptlib2.8.2 support H.263 codec inside?

2) If the above response is YES, Are you suggesting any H.263 DLL file?

3) I find a source that name is “H.263-1998” then I download that and compiles it but I find below Error inside:

I try to solve this problem by download a “libavcodec” that use some header & DLL file that I copy in “C:\opal\plugin\video\common” but I take below error:

1>------ Build started: Project: H.263-1998 (FFMPEG) Video Codec, Configuration: Debug Win32 ------

Please guide me to i can have H.263 codec with DLL & source over OpenPhone 3.8.2 here.

I am in wait for your response.

Best Regards.
