Integrate YoutubeThrottlingDecoder into exoplayer

• Bugfix (user facing)

Description of the changes in your PR

old

Going with this https://exoplayer.dev/customization.html#customizing-server-interactions the `ResolvingDataSource.Resolver` should be called, but it isn't. I think it has something to do with exoplayer using different Extractors depending on the media type, see https://exoplayer.dev/doc/reference/com/google/android/exoplayer2/source/ProgressiveMediaSource.html . But I once again have no clue why it's not calling my resolver since, MP4 is a Progressive media type, see https://exoplayer.dev/supported-formats.html#progressive-container-formats

Apply YoutubeThrottlingDecoder when fetching more of a video. This only solves streaming, not downloading

The code is shit and it most likely broke some other stuff, but for know i just want to know if this solves the throttling problem

Fixes the following issue(s)

Hey, so I installed this debug apk for testing, but have unfortunately now run into the buffering issue using it.
This time, the video played fine for a minute or so, which is different from how it usually works with the "main" app, where it occurs immediately upon playing a video. Again, I barely know what I am doing, but I have created another logcat here

2021-07-17-yt-throttling.log

This is a log of the buffering issue starting, where I filtered the log using the word "newpipe". It's just one line repeating itself.

2021-07-17-yt-throttling-2.log

Same log, but this time filtered using the PID. Much more detailed.

[XiangRongLin]

Thanks for the logs. Luckily it was just a simple error on my part of replacing the wrong thing inside the url. I updated the debug apk at the top

[mvasl]

I can confirm that this PR fixes the issue for me.
POCO X3, Android 11.

It seems to have gotten more resistant to throttling, but not fixed for me. What's weird is that it seems to be getting fixed (most of the times) when switching to popup player, but buffering is throttled again when switching back to normal player.

Try watching this video in 3x.

Its not there in current newpipe. Only debug version

[XiangRongLin]

I updated the apk with the changes from the extractor. Functionality-wise nothing changed

[Thewisem]

It didn't fix the lag when 3x is done on that video

[njmdietrich]

I have run into the buffering issue using this version (though not the one with the changes from extractor, I hope that doesn't matter), although this time, instead of only playing for a second or two between buffering, it played for maybe 10 seconds at a time or so. But again, force closing the app was the only way to get it to play seamlessly.
I managed to record another log and filtered it. (hopefully correctly!)
The video in question

[opusforlife2]

So I've been using this PR for the whole of last week, and I have encountered the rapid buffering issue only a couple of times. But fortunately, it lasted for only 10 seconds or so, and then the buffer immediately expanded, loading 50 seconds ahead as expected.

[bibin-v2020]

The issue is not fixed completely in this apk but can see some improvements..

• Buffering for some second's initially and then back to normal speed
• Wipe Cache Data always fix the issue for me
• Using Android 11 (Realme 3 Pro)

[infinitewaveparticle]

I used this apk successfully (no buffering) for 4 days, but today, after watching 2 videos, the issue has returned for every single video. I can no longer watch any videos above 360p and most I have to watch at 240p or 144p. I really want to use NewPipe. I love it. I appreciate all the hard work you put into it too. I will continue using it daily until this issue happens, and then I will use Vanced.

These changes are not needed anymore. Closing in favor of #6792
