2. Click download ( I always choose 4 threads)

Expected behavior

Expected the download speed be fast around 3-4 MB/s consistently since I had 50mbps connection.

Initially the download speed be fast but it then throttle to 5-30kbps.
The only way to bypass is manually pause and start when see it throttle until the download finished

Unfortunately, that's YouTube which is throttling more and more streams (generally when HTTP chunk size reaches 10MB) when you are not using the same way official clients use to fetch streams.

Could you try the APK of TeamNewPipe/NewPipeExtractor#780 and see if by any chance, the issue is solved? Thank you in advance.

You may also try as a workaround to set 32 download threads.

I tested the debug apk but the issue still persists. (Edit issue still persists in version 0.23.1)

The workaround of 32 threads will still throttle but it takes a bit longer before the speed was throttle down.

Since it was Youtube feel free to close the issue if needed.

I noticed the same thing, freezing the download during or towards the end. If at the end of the download then I pause and redo the download, then it is complete.

Android 10

Current version of Newpipe 0.22.1

3 or 4 threads of downloading.

Yeah, I remember when this started happening to me a few years ago, though at the time I thought it was due to my had cellular reception (I have always had 32 download threads set).

Nowadays, I just figured it must be YouTube throttling all connections, so I didn't think of posting a big report.
For me, it generally starts throttling at ~88-98%.

There is a strange problem with some video files from YT. The downloaded file in the place where originally something is shown is unchanged as if in a loop although the sound is OK. In the original YT application there is no such problem. Moreover, when the VLC player plays such a file to the end of the original time it continues to play this "looped" video significantly exceeding the original duration. Presumably the strange download occurs when there is a stop download, then I pause the download and then resume. This is mainly when I notice the strange problem.

This problem with incompatibility of the video downloaded via newpipe and the original is currently only noticed on one particular channel. It's not the first time this has happened, on a previous version of NP it sometimes happened too. Shadow ban??? The timeout in your program mpv also occurs when a download from that particular channel is inconsistent with the original and shows the video in a loop. Maybe I will prepare a separate topic with examples but unfortunately it will take a while through the template.
P.s. I downloaded the same video using another competing program and there is a 100% compatibility with the original as well as with the native YT.
