Hardware-accelerated transcoding (#41)

Browse Source 
* add qsv transcoding support

* add basic nvenc support

* add nvenc to docker-compose

* add vaapi hardware acceleration

* add vaapi driver to dockerfile

* raise ffmpeg log level

* lots of progress with nvenc, qsv and vaapi remain untested

* qsv fixes

* code cleanup
