Hi, gstreamer-devel:     1. Consider "decodebin" for demux & decode your media file automatically.     2. You mentioned "encode this file into a perticular format", so why you wanna find encoder & rtppayloader dynamically ? You should link your specified encoder to decodebin then link rtppayloader, that's all.

Now I want to find the encoder dynamically and link with the decoder. Similarly I also need to dynamically link the rtp payloaders. But I am not able to do it. Could anyone help me regarding the same.
