OK you are using 1.19.5. There has been some improvements in the current CVS which changes the detection method of extended video capability. You should be using the CVS version.

I hope to have the next and first stable release 1.20 available within the next couple of weeks.

I think the reason why dynamic H263 codec is not being loaded is because of the flags field in PluginCodec_Definition

For dynamic codec flag is

PluginCodec_MediaTypeVideo | // audio codec PluginCodec_MediaTypeExtVideo | //extended video PluginCodec_RTPTypeExplicit, // specified RTP type

which makes up value of 69.

Now in H323PluginCodecManager::RegisterCodecs() function

the check ( videoSupported && ((encoder.flags & PluginCodec_MediaTypeMask) == PluginCodec_MediaTypeVideo ) && strcmp(encoder.sourceFormat, "YUV420P") == 0 )

fails because (encoder.flags & PluginCodec_MediaTypeMask) == 5 and PluginCodec_MediaTypeVideo = 4 . There is no flag check for extended video. So the codec is not loaded. I am using H323plus version 1.19.5 downloaded from h323plus site.

I am just calling AddAllCapabilities(0, 0, "*") to load the plugins. Is there something else to be done to load extended video capabilities because I think this call is not loading extended video codecs because of the reason mentioned above.
