You are talking about streaming, right?
Is this also happening with en external video player, e.g. VLC?

Dear Tobias Kaminsky I try use VLC can play video Thank you for support

[Se7endevil]

I will upload file m2ts to app nextcloud. but can't show play video and not streaming external app. BR.

[tobiasKaminsky]

Not sure if m2ts is supported.
Can you first try it with a regular mpeg2 file?

I can confirm almost the same issue on an Samsung Galaxy S8 with latest NC app 3.11. With NC app version lower 3.11 there was never a problem to stream smoothly mp4 files directly in the app. No matter file size and quality.
Since updated to 3.11 just small files are streaming with a lot of buffering. Large files do not load or take almost hours to load.
The same happens when using vlc og mediaplayer on mobilephone.

Streaming the same mp4 files in webbrowser is working fine as expected.

So, I have ran into a similar issue with two android phones (OnePlus 5T and OnePlus 6T), NC app 3.11.1 installed.

Tested with both the "default" intro video file that came with the installation (Nextcloud intro.mp4) as well as manually uploaded video.
When opening over the Web browser, it works flawlessly.
When opening from within the app, it gets stuck on loading for exactly 30 seconds before it says "The built-in media player is unable to play the media file. Sorry."
In the app logs, this is the only error I could find:
2020-05-07T01:25:35.403+0100;E;PreviewMediaFragment;Error in video playback, what = 1, extra = -2147483648

When opening from the app using "Stream with..." and picking VLC, it gets stuck on the loading part for almost precisely 300 seconds before it starts buffering/downloading the file (I don't see any real bandwidth being used before then, doesn't really matter so much on the size of the file, after which it starts to play the file in VLC).

I have also tested it with https://demo2.nextcloud.com, and built-in player works fine actually on android app, no issues.

I don't see anything useful in the app logs except that one line, and nextcloud.log doesn't have anything in this time frame at all.

Just a quick update, once I have enabled LetsEncrypt certs on my NC server, everything is working fine in the app. Seems that if the certs are not trusted on Android, it will fail to stream properly for some reason.

Dear Team nextcloud Thank you for support I will use VLC. it can fast forward and play continue. Best regards. Setta ในวันที่ พฤ. 7 พ.ค. 2020 เวลา 09:25 nijezauzeto <notifications@github.com> เขียนว่า:

I am using LetsEncrypt certs. Is there a way to update certs in the NC app without reinstalling the app?

[nijezauzeto]

I believe this would happen on its own if you were to remove your current account from the app. Once you get to the "Log in" page and enter the URL of your server with the valid certs, it should refresh them into the app, but that is only a guess.
Basically I have enabled LetsEncrypt on the server side, deleted my account from the app and used app code from the security tab to authenticate against the app. After that all worked on its own. I haven't done anything with the certs on the android/app itself.

I can confirm the same issue on my Huawei P30 with latest NC app 3.11 even after reinstalling the android app and login with new app token. VLC and Webbrowser are working fine.
