Immense thanks, on my native language, when relistening to search for something that was said, I can keep up with 3.75 speed. So this will be very usefull from time to time.

And more rarely, when searching for something visually and when the timeline preview isn't enough, greater speeds like x5 are useful too. I usually use x8 in PipePipe (it could go to x10 but it bugs and goes back to x8, it might be my phone or an exoplayer bug) but maybe the UX for selecting speeds with precision (like comming back to x1) would be too hard so x5 as a maximum is a good simple step forward 😀

You're welcome. Actually It would be good if this PR will be merged to Tubular. Are you planning to open a PR in Tubular? (as I archived my fork bcs lack of time and won't merge it unfortunatelly) @klaviartur
