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 *** *
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.

The MPEG4 is defined in H.245 Annex E and it is a generic codec Follow the same principals as the H.264 code (which is also generic)
