Preferences window

Currently there is an implementation of the layout of a Preferences window, but it is still not implemented.

Here is a screenshot:

Really interesting!!! Usually I use Jdownloader when I want to extract the music track, cause JDownloader let me choose between ogg (opus), m4a (mp4) and other containers and the quality. It would be very interesting if your implementation let user not only select "Quality" but container and quality as kbps not as generic like "Medium", "Low" ... etc.
Thanks!!!

That's because Youtube gives you a bunch of URLs of streams for different formats and qualities. Based on that information, it is not very easy to find the right format and bitrate pair as you are suggesting. To be able to choose the quality, I created a simple rating system that categorizes each stream and then it picks one for each quality level. It can happen for example to use the same stream in high and low quality. It will depend in how Youtube had store the video.
It is possible (and probably is useful) to implement what you suggested with the help of a transcoder, but I have no plans to that. It will add extra complexity with little in return.
But unfortunately I'm not been able to work on this project at all... :(

You must understand that for users looking for not proprietary format, to have the ogg format option (using opus codec) is very important. Really I don't know if JDownloader uses FFmpeg in background to make the conversion or is YouTube who make all possible format/bitrates available for download :(
