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

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.

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.

Hello, same problem here, videos plays on desktop but not on app.
The video files are from a SMB share mounted with "external storage" plugin.
The Nextcloud intro.mp4 doesn't work either.
Phone: Galaxy note 9.

Tested with the mobile website in chrome on my galaxy note 9 and it works.
So only the app cannot retrieve the file, and even if I want to make it play with an external player, that player would not receive the file.
So it looks like it not event the app that cannot play, it's the app that don't receive the .mp4 at all

At start download from 0 to end and when has a minimum buffer start the video, when you seek video him stop the download and start a new download from seek to end, when has all the data the video is abailable in offline (download completed). In network you can fin several material or lib for a proxy

Thanks for insights how you handle it on iOS.

Maybe we can wait for buffer: https://developer.android.com/reference/android/widget/VideoView#getBufferPercentage()

And if this is too low, we wait and resume automatically if buffer is filled again.

There is an experimental switch to another video player in #8132 (comment)

This apk can be installed in parallel.
It would be great if you can give this a test, if it helps in your scenario.

Wotisrv commented Mar 8, 2021

I am testing the development apk. Where to wright comments? This edition is playing fine all my videofiles, no matter what filesize.

Missing: full-screen support
Issue: when clicking back while video is playing the video does not stop. It continues playing in the background. Sound is playing but no video to see and no possibility to stop. Need to reboot the mobile phone.
Clicking stop first and so back is working fine.

Thanks for testing.
Then this is the way to go, and to make this working reliable.
As it was only a quick & dirty test, such problems like playing all the time or no full screen were expected.

My mistake. I expressed myself wrong.
For a while ago I wrote in the thread that I observed the same behavior with the NC app on iOS and also got feedback from users using the NC app on iOS, that they cannot stream. Now I thought, if the ExoPlayer is the solution in the NC app for Android, is it maybe also for iOS? Sorry if I'm wrong.

szaimen commented Mar 9, 2021

Since the Exoplayer is only for Android, this won't be possible.
But videostreaming does already work with the NC iOS app, in my experience...

Ok thanks for feedback. I will take a more accurate test with iOS and not mix it here.

Setting up valid certs fixed this for me. Valid certs (not self-signed certs) are required to watch the media via the nextcloud app. In my case I have a certificate authority setup on windows server 2019, generate a csr on the client system, sign the cert on the ca, then present those two @ nextcloud/appdata/keys/cert.key & nextcloud/appdata/keys/cert.crt .

Apparently the android app requires TLSv1.2 when using WiFi. I had TLSv1.2 disabled in my ssl config, re-enabling it fixed it for me.
This also fixed another issue I had with not being able to upload files while on WiFi.

Do you know a way to do this with a Linux system? I just installed Nextcloud for the first time, uploaded 20 GB of my media, then tried streaming from my android and the video never loads. Tried "Stream with" to VLC and Plex, no luck. I don't want to make it public facing, it's solely for encrypted shared media storage between my home devices. But it seems, if the case is that it needs a proper cert, it's impossible to get it working without assigning a public domain to it?

Even with self signed certificates the Certificate Authority, the certificates you used to sign with, has a public and private key. On your PC you have probably said to trust a self signed certificate, and after that it stopped giving you an error. Same thing applies with a mobile device. You can add the public key of the CA to your mobile and you'll be good to go after that. You can Google to find help with words like, "how to add ca chain to phone android".
…

I'm aware of how to add a CA chain, but unsure how to get a CA working on a Linux system. If I was hosting NextCloud on Windows, I could follow your instructions above and simply paste those certs in their respective folders.

Try googling, "use linux as certificate authority". Is that what you are looking to do? If yes, find an article for your Linux distribution and I might be able to help out if you get stuck.
…

I can do that, but it doesn't help me with configuring anything on a NextCloud VM image for access. And that's only part of the equation, this is a stock NextCloud VM image. I need to be able to stream video from NextCloud to the Android app, but all I have is your comment stating a Windows CA cert helped you. No confirmation or update from NextCloud. There's no guarantee installing a third party CA (and potential security risk) and deploying a cert would work, nor does it seem possible.

Unfortunately, appdata doesn't exist in Linux. You would have to somehow integrate them into Apache I believe, and I have no clue how to even begin that. I've already had two instances get corrupt for trying to edit the configs, so it's frustrating there is a lack of documentation for it.

I used the full VM, https://www.hanssonit.se/nextcloud-vm/.

I just bumped into this but on NC 29 and I use browser as a client.

  • I use Firefox (latest to this date)
  • when I open video via Files menu item it starts loading and i see in NC log that my nginx starts to streaming the file
nextcloud_proxy  | 192.168.88.10 - - [01/Aug/2024:17:52:36 +0000] "GET /remote.php/dav/files/n1/photos/UNSORTED/VID_20240722_223008_HDR10PLUS.mp4 HTTP/1.1" 206 2377635 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:129.0) Gecko/20100101 Firefox/129.0" "-"

When I try to access the file on the URL from log downloading in my browser starts to I guess the file gets served just fine. However NC files start loading the player and then I get

@im-n1 Looking at you Firefox log. You don't have the correct codec installed for Firefox to load the video. Firefox on Linux uses libavcodec to play most MP4 files. Try sudo apt install libavcodec

I just tried and the lib is installed (I even updated it to 61).

The vedio test page https://tekeye.uk/html/html5-video-test-page play mp4 just fine. Looks like mp4 is totally playable in my browser. It it possible that it might be just the video I try to play? Or anything else?
