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.
