To fix 1002 errors Piped project disabled ump with this commit: https://github.com/TeamPiped/Piped-Backend/commit/d5572d70a77ca6db1d0381bd506ae85cf8047468

Which breaks DASH for some reason

[VitoItalianGamer]

Can you guys fix this issue?

[Not-A-Coder2023]

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

edit: GrapheneOS Android 14 Pixel 6a

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;

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).

[VitoItalianGamer]

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

[CarlosRuiz-globalqss]

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

[Bnyro]

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.

[ARR552]

This happened to me just recently

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

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.

[VitoItalianGamer]

How do I enable UMP in libretube?

[aviallon]

Would implementing an MPV player fix the issue? MPV can play almost every thing, after all. I know Findroid (native Android client for Jellyfin) had a very good MPV player integration that just works when enabled.

[VitoItalianGamer]

I got Findroid how do I add a server to it?

[sonisaltiner]

Greetings. Is there a problem with entity? Occasionally entitys starting with the prefix Kavin disappear. If I select any other occurrence, there are problems, some things stay loading.

[Moonstone3010]

Hi, I've been having the same problem for (I think) a few weeks now. No video is playing, it shows the message: source error. This is independent of the instance. Piped in the browser works on the same device. A workaround for this problem is to disable the piped proxy. When videos are sucked directly from YT everything works. The second solution is to enable HLS instead of DASH, but - as someone wrote above - in version 0.22.2 this does not work in audio-only mode.

edit: I also tested last nightly and HLS audio-only playback works, but the main problem remains unsolved.

[sonisaltiner]

@Moonstone3010 Thank you for your reply. Solution 2 seems to work. Solution 1 causes a different problem. The videos open but do not play. I hope you are working on these issues.

[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...

[VitoItalianGamer]

I know everybody has the same issue and when will the issue be fixed?

[aviallon]

@Bnyro could something like an automatic fallback be implemented?

Also, I think trying to use MPV as the player might help there, although it would probably be a major pita to add.

Yeah...at this point I think that too. Maybe the current player implementation lack of some codec, useful to correctly decode the video stream.

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 ...

[Pamilg8]

The YouTube app uses the Android Testsuite or the iOS YouTube API instead of the default Android YouTube API for video player requests. This is why the videos don't work. But how can the problem be solved? Maybe in NewPipe Extractor. But in NewPipe, videos open smoothly. Maybe this should be fixed in Piped

[mckellenjaundice122]

Ever since December I haven't been able to use the app at all, nothing has changed, it's just as broken even with all the default settings. Only way I can get anything to play is to disable the piped proxy, the hls setting does absolutely nothing whether off or on for me

YouTube blocks LibreTube and servers are sometimes down (initial player not response). It seems that the ipv6 rotator is not implemented. YouTube proxy is not reliable. NewPipe is more stable. Innertube or NewPipe Extractor as additional support would be great

[VitoItalianGamer]

I'll install New Pipe until LibreTube fixes the DASH problem

You can simply disable the proxying in the settings. Go to settings -> Instance and select 'Disable Piped proxy'. That setting will make LibreTube basically act just like NewPipe.

i have the same issue here, video not loading at all but for specific channels like Ohara, Joseph Blaze and TheAvatarist.

[VitoItalianGamer]

Ok

[VitoItalianGamer]

But there is no auto generated captions.

[Not-A-Coder2023]

unrelated but apparently adding a channel to a group crashes libretube debug
