Thank you. I will try to correct.

Plese try now with iTunes. Same errors corrected.

Working for me as well, good stuff.

Thank you for comment. I have same problems with ffmpeg conversion. I'm working to correct problem.

Yes. Youtube-dl and ffmpeg. Code will be posted on github.

great! look forward to seeing it.

I thought about it, but it complicates the procedure.

Take the original audio stream to reduce losses and always use the best quality video for the audio track source. Youtube already transcodes on upload, you don't want to have three steps of loss in the output.

Unless you're dealing with 10min+ videos, the size difference in the mp3s won't matter anyways.

If there's competition will be good for shoppers.

The algorithm games can not be patented (licensed). Only the name and design.

I thought I'd ask for a goal 3^6 (729). But this is impossible with this algorithm.

243 243 243 x x

81 81 81 x x

27 27 27 x x

9 9 9 x x

3 3 3 x x

What about if I move target to 729 (3^6)?
