SRT protocol expect packets of size around 1300 bytes. Also, it's not
really meant to be used without a container.

Most users will send a transport streams (mpegtsmux) to the element, and
use the alignment to control the size (alignment being a number of TS
packet, so N * 188 bytes). On top of which, you may need to pick a
compression method. Unfortunately, you have to know these things to use
GStreamer, but we can help here.
