refactor(server): video transcode processor (#2163)
* refactor(server): video transcode processor * refactor: rename shouldRotate to isVideoVertical, remove unnecessary await * refactor: rename getOptions to getFfmpegOptions to be clearer in that context * fix: optimal preset converting vertical videos already smaller than target resolution --------- Co-authored-by: Zack Pollard <zackpollard@ymail.com>
