To fix 1002 errors Piped project disabled ump with this commit: TeamPiped/Piped-Backend@d5572d7

Which breaks DASH for some reason

This happened to me just recently

Try disabling DASH in settings. Worked for me, probably will for you as well

This did it for me.
Settings -> Audio and video -> Quality -> Use HLS

edit2: it pauses every few minutes now, though

For those using libretube with a selfhosted piped server with docker, where switching to HLS doesn't seem to work and where the backend got updated recently by watchtower;

1337kavin/piped@sha256:afa51dbe3089686e42e894a405dabf7cc6f649b739c4f801c766153bf7a96a3c is the image with digestID just before the update that disabled UMP and breaks DASH as mentioned by @ngn13.

Currently using this image, back up and running, till the issue git fixed.

Debug log shows the issue comes from ExoPlayer:

The DASH manifest created using PlayerHelper::createDashSource works fine using other video player, including Piped (shaka-player).

I'm using hls and the auto generated captions don't appear.

I'm using hls and the auto generated captions don't appear.

same here - DASH is not working, and HLS is slow and without automatic subtitles

I've logged and compared requests from Piped and LibreTube at the proxy's side, and they're pretty much identical. So I suspect that when disabling ump, YouTube's video format is different and thus no longer compatible with the ExoPlayer, while Shaka does handle things differently at the Piped frontend on the web.

I've tested downgrading the ExoPlayer version - without any notable changes.

This worked for me as well but only for the video. It is still failing in audio mode...

The audio player did not respect the Use HLS setting and always used DASH. This issue was resolved in #5862. You can expect it to be resolved in the next release or try the nightly builds.

[Bnyro]

Please ONLY comment here if you have useful information on how to solve the issue at LibreTube's or Piped proxy's side.

It's not helpful to say that the issue exists for you too - everybody has the same issue...

[0xrxL]

UPDATE: seems DASH working again on this debug build, I can even watch the age restricted videos (with a custom piped instance, obviously), but there's no specifically merged code related to it.
What happened? 🤔🤷‍♂️

You certainly disabled the proxy ...

I checked it, and it's disabled. But I wasn't able to make restricted video working on current stable version (also with proxy disabled).

So I wondered if there was a fix (or fixes) merged recently.

[Bnyro]

No ...
