[h323plus] Unable to load H.263 and H.264 plugin dll for x64 windows

To update my previous post, I can now load H.261 codec after copy the plugin to the ptlib plugin directory. The problem was because the application only search the ptlib plugin directory by default and not the application's directory. Nevertheless, the video does not seems to be working properly. It raises unhandled exception on calling codec->codecFunction (h323pluginmgr.cxx line 1783). 
Simon, you mentioned that you tested the H.261 x64, do you have any issue in the video (en)coding?
I also recompiled the H.263-ffmpeg plugin in 64 bit successfully , but it is not loaded in H323 application. The tracing output show that "Plugin Codec DLL h263ffmpeg_ptplugin contains no codec definitions". What does this error means? how can I get around this problem?
Thanks for any help.

I checked out the H.261 projects from CVS and compiled it without any problem. However, I still cannot see the codec loaded in the simpleplus application, despite I have placed the plugin file on the same folder as simpleplus.exe. I have also double checked to ensure that I am using x64 ptlib and h323 libraries. Any idea what I have done wrong?

Jess X64 support is definitely a work in progress. To load the audio/video plugins the files also have to be compiled x64. I just checked in and tested vs2010 x64 support for H.261 but beyond that you are on your own. You will need to compile the H.263 and H.264 plugins x64 and build your own x64 version of X264 and FFMPEG. Sorry I don’t yet have prebuilt x64 binaries.

Subject: [h323plus] Unable to load H.263 and H.264 plugin dll for x64 windows Hello, I have been trying to get 64-bit H323plus to work. Now I am struggling with getting the 64-bit H.263 (both H263-1998 and ffmpeg) and H.264 video plugins working on 64-bit H323plus application.  I upgraded the h263_2008.sln and h263ffmpeg_2008.sln to VS 2010 and x64 solution files. I am able to compile them successfully. I placed the dlls under the same folder as the simpleplus application. But I do not see the simpleplus application loads either of these h263 codecs. Has anyone tried to compile these plugin projects in 64-bit? I will greatly appreciate if anyone who has done this can share the compiled dlls or give me some guides on this...  I have not tried to recompile the H.264 plugin as I expect much more complication with that project, but I do hope can get the H.264 plugin working as well.  Best regards,Jess
