Yes, it should be a Generic capability as per H.245 Annex E.
Last time I looked the MPEG4 plug-in did not support H.323 at all. I will
talk to some others about adding the correct code.

Subject: [h323plus] How to add a generic Video Capability?
Hi
I have been able to build mpeg4 plugin code taken from opal cvs. Its
PluginCodec Definition has defined it as type
PluginCodec_H323Codec_nonStandard.
I have changed it to PluginCodec_H323Codec_generic and compiled it.
Should mpeg4 capability be added as generic or non-standard? What is the
difference between two?
My application is loading the dll perfectly fine now but the capabilities
are not being added because of the following reasons:
1.) Generic and non-standard video capabilties require
h323CapabilityData(last member in PluginCodec_Definition) to point to
generic capability data info. This has not been defined in opal plugin
code.
2.) H323Capability *CreateGenericVideoCap() is checking for
PluginCodec_H323GenericCodecData in PluginCodec_Definition and it is null
currently ,so capability is not created
Can someone help me in how to define generic capability data and what all
information it needs? I have recognized the structures in opalplugins.h but
don't know how to fill them with suitable values for mpeg4 plugin.
Please help
Thanks
