Set bitrate limits for transcoding (fixes #638) (#1135)
* Set bitrate limits for transcoding (fixes #638)
* added optimization script and test, changed stuff
* fix test, improve docs
* re-add optimize-old-videos script
* added documentation
* Don't optimize videos without valid UUID, or redundancy videos
* move getUUIDFromFilename
* fix tests?
* update torrent and file size, some more fixes/improvements
* use higher bitrate for high fps video, adjust bitrates
* add test video
* don't throw error if resolution is undefined
* generate test fixture on the fly
* use random noise video for bitrate test, add promise
* shorten test video to avoid timeout
* use existing function to optimize video
* various fixes
* increase test timeout
* limit test fixture size, add link
* test fixes
* add await
* more test fixes, add -b:v parameter
* replace ffmpeg wiki link
* fix ffmpeg params
* fix unit test
* add test fixture to .gitgnore
* add video transcoding fps model
* add missing file
