Limit FFMPEG threads

[supernova_ws]

FFmpeg always starts with "-threads auto" (or no threads-param at all).

It would be VERY nice if it will be option that can limit FFmpeg to a number of threads.

Config, console drop-down/input box etc - everything would be just fine. Because for now starting FFmpeg for transcoding/adding new file/retrieving meta info makes PC almost unresponsible.

This is already there, Transcoding tab in the console.

Oh! Sorry! Very strange - miss it. May be looked at one of the previous version and didn't look there too long.

Thank you for a great product!
