Merge video and audio to file

[Vivia Nikolaidou]

Hi,

If you notice, you have to give a name to mp4mux:

mp4mux name=m faststart=true

That's the meaning of the last "m." line: this should link to the
element that we named m. The last dot basically means "try to
automatically find a sink to use". In more complicated use cases,
you'd specify a sink name, like m.audio_0, but here you can leave it
blank as "m."

Hope it helps!
