Hello Mark,

Thanks for the info!  I also have another question about H.239, I am testing simple-application now, after connection and when I type "S" in callee-side(to start H.239), I got error message said "Application Open Error: Remote may not support Feature!",  does it mean I need to enable H.239 capability in caller-side first?  could you tell me how to make a H.239 enabled call with simple-application? do I need to modify the code of simple-application or just update the configuration?  Thanks!

Regards,
Bo

Did you install video plugins?

Using plugins

Installing a codec plugin consists of copying the DLL or library.so file into a directory where it can be found by OpenH323. By default, the stack will search "C:\PWLIB_PLUGINS" (on Windows) or "/usr/local/lib/pwlib" (on Unix) and all sub-directories. The default directory will be different if the --prefix option is passed to configure. 

At run-time, the default plugin directory can be changed by setting the value of PWLIBPLUGINDIR environment variable. If set, this variable is assumed to contain a list of directories, seperated by ":" (colon) on Unix, and ";" (semi-colon) on Windows.

All plugin codecs must have a name that ends in "_pwplugin.dll" (Windows) or "_pwplugin.so" (for Unix). This allows the plugin search path directory to be safely pointed at a directory like "/usr/lib" or "C:\WINDOWS\SYSTEM32" without PWLib attempting to load every single shared library while looking for codecs.

Hello Simon,

Thanks for the info! now I have compiled ptlib-2.10.1-src and h323plus-v1_23_0, also I have built two applications(simple and myphone). when I started them in my two PCs, I can do audio call successfully, but there is no video, could you tell me where I can find the document for adding video capability into simple/myphone application? Thanks!

GnuGk fully supports H.239 (most gatekeepers do) and can be used with H323plus to do H.239. You can do H.239 with or without a gatekeeper.

Hello Simon,

 

Thanks! 

 

could you also tell me if I want to make a H.239-enabled call with H323Plus terminal, do I also need a H.239-enabled gate-keeper? or I can use one H323Plus to make a H.239-enabled call to another H323plus directly?  Thanks!

 

also could you tell me if GnuGK supports H.239? Thanks!

 

Regards,

Bo
