splitmuxsink: documented pipeline example too simplistic to be useful

Submitted by min..@..arp.fm

Link to original bug (#759355)

Description

In the docs at http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-splitmuxsink.html an example pipeline is given where a single file stream is split into multiple individual files.

This example is excessively simple, only in rare cases will you ever want to deal with streams containing just video and nothing else. In typical real world usage, streams consisting of video, audio and subtitles are processed, and there is no workable example to demonstrate how this is done.

Given that the splitmuxsink element wraps the muxer element, how do you target the muxer element with sources?

None of this makes any sense.
