[h323plus] How to Add Extended Video Capability for H.239

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 (
((encoder.flags & PluginCodec_MediaTypeMask) ==
PluginCodec_MediaTypeVideo ) &&
strcmp(encoder.sourceFormat, "YUV420P") == 0
fails because (encoder.flags & PluginCodec_MediaTypeMask) == 5 and
= 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.
