Steps to reproduce the bug

Open this random stream.

Choose 720p as video quality.

Actual behaviour

Stream doesn't start on Foreground with 720p selected as quality.
Pressing Android home button and thus continuing the stream in background works fine.

Expected behavior

The video to be opened on 720p.

I can't find any useful information in the logcat, but I can reproduce the issue. I'll look further into this later, but I suppose it's just one more instance of an unsupported DASH stream

[opusforlife2]

@allendema The log seems to suggest you're using MP4. Can you try using WebM?

[allendema]

@opusforlife2 That does not resolve it.

[opusforlife2]

Oh. That stream is not random at all. @wb9688 this is one of those DASH videos. There is only a 360p and 720p stream. We know 360p and 1080p play correctly, but this rogue 720p has some issue. I can't play it either.

[Stypox]

Shouldn't those be blacklisted by TeamNewPipe/NewPipeExtractor#400?

[opusforlife2]

If they're not OTF streams, then no. 360p is a known progressive HTTP stream. This 720p is the unknown quantity.

So all DASH video streams are trimmed by TeamNewPipe/NewPipeExtractor#400, but two normal resolutions remain: 360p and 720p, as NewPipe shows. I don't know why the 720p resolution would not work: even exoplayer does not write anything in the logcat (I tested this with an emulator).

[opusforlife2]

I don't know why the 360p resolution would not work

I don't know either, because as I said, it does work. 🤔

1. Open this random stream.
2. Choose 720p as video quality.

The video cannot be downloaded (720p) using youtube-dl so I don't think it's NewPipe's issue.

[Stypox]

@xibr is there a report for this bug on youtube-dl's repo?

[xibr]

I think this issue youtube-dl#3721

[Stypox]

Oh, then this is a YouTube issue. We should implement automatic fallbacks, though, when a resolution raises an error
