[h323plus] Optmized version os libs

All video codecs in h323plus are plugin. Seperate files which are read in at startup with your application. These plugins are just generic c/c++ code which do not need linking to the main h323plus library. There are plugins for H.261,H.263 and a H.264 under testing. The H.263 and H.264 plugins use the FFMPEG library however having the AMD option would be good. The best place to start would be to look at the H.263 plugin which is available with the A/V plugins (Linux) from the H323plus website. Knowledge of the interworkings of h323plus is not needed although you may need assistance with how the plugins are linked in and used in the library.

If you need further assistance please let me know.

  To not spend work in reinventing the wheel I want to know if there are people working in the codecs and PColourConverter classes using the AMD Performance Library.

  AMD is providing the APL lib in Linux, Windows and Solaris flavours, and they version of GNU GCC 4 for RH and SuSe.

  I'm woking in a project for use in internet2, so I'll 'spend' some time in create of a RAW YVU420 codec, but reading the APL manuals they provide suport for H.264 :). If some have interest or already in the same effort....

  If someone already have a RAW codec or already using the APL please can share some hints on sourceforge forums of this project, I'll be pleased.

  Other question I have is how to add the H.263 video capability in H323Plus, I'm new to the H.323 and openH323 implementation and I am a bit lost with the modifications in H323plus.

  When the work is done I'll ask to put the code or the link it to the internet (it's a project sponsored by the government for a public university so, I think I'll have no problems in sharing the codes produced/modified)
