What's in this PR?

I added the ffmpeg parameter adaptation_sets for dash streams

Why?

When testing DASH mpd generated by this project, the different qualities (representations) were not properly recognized in the dash.js reference player: http://reference.dashif.org/dash.js/nightly/samples/dash-if-reference-player/index.html

I tested with other players and none of them recognized the different representations until I added the adaptation_sets parameter.

BC Breaks/Deprecations

Probably breaks support for subtitles? I am not sure if it is even supported by the project.
