Api endpoint for .m3u8 playlist link

[Anishyou]

Hi everyone,

I'm working on an integration between Artemis, an open-source learning platform, and TUM-Live

I need to retrieve the .m3u8 playlist link for a given lecture video so it can be played directly inside a custom video player in Artemis. Ideally, I'm looking for an API endpoint from TUM-Live (or any relevant backend) that:

Returns a .m3u8 HLS playlist URL for a specific lecture video,
Works securely (e.g., with JWT tokens or session-based access),

And can be consumed server-side (e.g., by our Artemis backend)
Does such an endpoint exist officially, or has anyone integrated something similar?

Any help or documentation links would be greatly appreciated. Thanks!

Have you seen our proto spec?

gocast/apiv2/server/apiv2.proto

Line 203 in fe27e2b

rpc getStreamPlaylist(GetStreamPlaylistRequest) returns (GetStreamPlaylistResponse) {

Note: This will only be possible for lectures that are public or hidden. Any streams that require user login won't be obtainable from Artemis servers.

I recommend embeding streams via iframes, adding ?stream_only=1 to any video will yield an embeddable website, e.g. https://live.rbg.tum.de/w/SoSe25SFoL/57786?video_only=1

Thank you for your response,
I will look into the given proto spec
Also We're currently embedding with iframe approach as you suggested, but the reason we're exploring direct .m3u8 access is to implement features like transcript generation, display with clickable segments (jump-to-time) and slide sync — which aren’t possible within an iframe.

If there's any plan to expose that RPC via gRPC gateway or REST, even for public/hidden videos, it would be super helpful for projects like ours (we're using video.js to build a custom player in Artemis).

Thanks again — this helps a lot!

This should be helpful to: https://tum.live/api/v2/docs/

Btw, video sections/segments and transcripts are already features in TUM-Live. Some of the work might be well invested in making those features available in embeded videos too instead of rebuilding an existing feature. But that's just my two cents :)

[Anishyou]

Well I had this understanding that TUM-live doesnt have enough resources to provide transcript generation on videos. Has it changed?

Also, I tried to access the endpoint with https://tum.live/api/v2/streams/57786
As this is a public video https://live.rbg.tum.de/w/SoSe25SFoL/57786

@joschahenningsen I would also like to ask if the following is possible.
Would it be possible to save a video as .mp4 format on TUM-LIVE databse through Artemis and we can fetch as requested?
In short, I wanna create a feature where a video can be uplaoded on artemis and if possible be saved on TUM-live

[joschahenningsen]

We don't have a public API that allows either, uploading or downloading videos from or to tum live.

You are welcome to propose an implementation and send a pr if the proposal is accepted, but I doubt getting authentication/authorisation for such API right is going to be trivial.

[joschahenningsen]

To me it sounds like you want to use tum live as a generic file hosting service or cdn. I think there are tools that are more fit for your requirements.

@joschahenningsen
Thank you for your response and yes I looked into it and will implement accordingly
As you mentioned earlier that public/hidden videos playlist link can be accessed via the https://tum.live/api/v2/docs/.

I have tried the swagger UI and request URL is
http://localhost:8081/api/v2/streams/55921/playlist

Also I tried https://tum.live/api/v2/streams/57786 .
I get missing cookie header, probbaly requires authentication for the token.

I greatly appreciate your help regarding this.

You mentioned earlier, that you want to create transcripts and clickable segments within Artemis.

TUM-Live already provides these features in theory. In the Admin View, you can create video sections that are clickable for students. Additionally TUM-Live also has the option for subtitles, however, these aren't created automatically yet but can be added manually, would this be an option for you?

[Anishyou]

Hi, thank you for your reply.
As Joscha mentioned before that I would be able to access public or hidden videos. I tried using the api https://tum.live/api/v2/streams/57786/
But it still does not work. I checked around and there was a PR opened for it. As it has been merged. I would like to ask when it will be live or when I can use it?
