Hi,Sir and Miss:
      I compile the plugin code H.264 and MPEG4-ffmpeg of opal-3.5.0.there are two problem.
     (BTW:#define LIBAVCODEC_VERSION      51.14.0)

============================================================
      1.For H.264.
      I compile successfuly and general h264-x264_pwplugin.dll,but both opalvoip and myphone2 can not find the plugin code.I debug the project "X264 H.264 Video Codec",
<1>FFMPEGLibraryInstance.Load() successfully
<2>H264EncCtxInstance.Load()    successfully
<3> *count = sizeof(h264CodecDefn) / sizeof(struct PluginCodec_Definition);
I can get the *count = 2.

In Myphone.
the function "H323PluginCodecManager::RegisterCodecs(unsigned int count, void * _codecList)" also successfully.

============================================================
2.For MPEG4
I compile successfuly and general ffmpegMpeg4_pwplugin.dll.and myphone2 also can find the plugin code.
