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
