If you want audio as well, you could mux your audio+video streams into a
container such as MPEG-TS (mpegtsmux) or matroska (matroskamux).

Are you re-encoding to a specific format on purpose here by the way? If
you know the client side supports all formats (containers/codecs) you
want to stream, you could stream directly without decoding+re-encoding.

You also don't really need the rtp payloading/depayloading here, esp.
not if you're using gdppay/depay as well (which you shouldn't if you're
using a proper container format).

There's also gst-rtsp-server, which supports streaming over UDP as well
as TCP.
