Using C-API based pipelines in RTSP server (without "launch" arg)

[Dmitry Valento]

Hello!

I want to create a RTSP server, which will provide several different 
multicast streams. These streams are based on pipelines, which created 
using C API (gst_element_factory_make, gst_bin_add_many, 
gst_element_link_many, g_object_set).
Therefore the method " gst_rtsp_media_factory_set_launch" couldn't be used.

Could you please give me a list of steps, which I have to implement for 
use C-API based pipelines in RTSP server?

Thank you
Dmitry
