Hi Wim, Thanks for the reply. I will look into the TI encoder plugin and make the appropriate changes. Any suggestion for me to go ahead with the RTSP??? Sorry, I forgot to attach the files last time. Thanks.

It seems the TI encoder does not provide this config string and thus the payloader can not create output caps. We could probably fix the payloader to not output anything before the config string was found. If you file a bug, I'll look into that.
