Hey, I'm trying to test the WebRTC live-streaming feature and seeing some issues.
I managed to get a WHIP live input working (see attached image). I'm also aware of the beta limitations (https://developers.cloudflare.com/stream/webrtc-beta/#limitations-while-in-beta), and to my understanding I should be able to consume this stream using WHEP. However, with every player I've tried so far the stream failed to load.

Additional context that might be relevant -
For this test I'm using an RTSP test stream with H.264 encoding (on MediaMTX) and publishing to cloudflare using a gstreamer pipeline with "whipsink" (which is listed as gst-plugins-rs here - https://developers.cloudflare.com/stream/webrtc-beta/#whip).

Did anyone manage to get this feature to work?
I'm currently subscribed to the live-streaming service based solely on this use-case - I'd really appreciate your help getting it to work (or at least some pointers on how to debug this further). :MeowHeartCloudflare:

To me it looks like the issue might be on the MediaMTX side. CF is only receiving 200kbps which is obviously incorrect which means something about your pipeline is not working

I want to host a video editor SaaS, where I need to store high quality versions of files for rendering and want to get low quality previews for displaying in my editor. Can I use R2 or MUST use Stream for this? And would Stream allow me to retrieve the originally uploaded file?

Voxus•3/6/25, 9:21 AM

It's not against their TOS?

Voxus•3/6/25, 9:21 AM

I got so confused

Voxus•3/6/25, 9:21 AM

Since it says serving large video files from R2 is not what they want

1984 Ford Laser•3/6/25, 9:22 AM

think HLS manifest/segments

1984 Ford Laser•3/6/25, 9:22 AM

or if youre encoding low enough quality you might be right. I think its best to keep filesize below 500MB to be safe?

Voxus•3/6/25, 9:23 AM

Okay that's fair, and so if I didnt convert into smaller videos, and just served the larger files in my editor that'd be against TOS?

Voxus•3/6/25, 9:23 AM

It's not a classic streaming site use case that's why I'm confused

MMD yeah, and it'd be a terrible user experience cos you're asking them to download ...

Voxus•3/6/25, 9:24 AM

yes absolutely hence why I wanna generate a low quality preview

Voxus•3/6/25, 9:24 AM

Can I build any worker inside of Cloudflare for that?

1984 Ford Laser•3/6/25, 9:24 AM

Is your software cloud based?

Voxus•3/6/25, 9:24 AM

Yea obviously, more asking, is there a video transcoding (compressing files) thing in cloudflare

VVoxus Yea obviously, more asking, is there a video transcoding (compressing files) thi...

1984 Ford Laser•3/6/25, 9:25 AM

No there isnt

Voxus•3/6/25, 9:25 AM

or would I need to setup a worker to call a transcoding service

11984 Ford Laser No there isnt

Voxus•3/6/25, 9:25 AM

alr appreciate it

1984 Ford Laser•3/6/25, 9:25 AM

Good luck getting a Worker to do that in an economical way

11984 Ford Laser Is your software cloud based?

Voxus•3/6/25, 9:25 AM

yes

1984 Ford Laser•3/6/25, 9:25 AM

I really want a transcode option for Workers

1984 Ford Laser•3/6/25, 9:25 AM

top of my wishlist

Voxus•3/6/25, 9:25 AM

unfortunately not

Voxus•3/6/25, 9:25 AM

I tried with ffmpeg.wasm

Voxus•3/6/25, 9:25 AM

but its so terribly slow

Voxus•3/6/25, 9:26 AM

it was transcoding at 200kb/s

1984 Ford Laser•3/6/25, 9:26 AM

That would have been my suggestion lol

Voxus•3/6/25, 9:26 AM

which even for a 20mb file it took minutes

1984 Ford Laser•3/6/25, 9:26 AM

as in ffmpeg.wasm running in browser or in worker?

Voxus•3/6/25, 9:26 AM

browser of the user

MMD (forgive me i'm from audio land where we have sensible file sizes)

1984 Ford Laser•3/6/25, 9:26 AM

delivering video is so cooked

Voxus•3/6/25, 9:26 AM

yea

Voxus•3/6/25, 9:26 AM

i could obviously build an instance that I call that transcodes

Voxus•3/6/25, 9:27 AM

but scalability and managment would be terrible

1984 Ford Laser•3/6/25, 9:27 AM

Yeah for your use case you might be better off with some sort of intermediate server that can handle transcode

1984 Ford Laser•3/6/25, 9:27 AM

Depending on the business case and plan for revenue making

Voxus•3/6/25, 9:28 AM

I did look into AWS, Azure and GC with their on the fly transcoding but their storage egress would kill me with an editor

1984 Ford Laser•3/6/25, 9:28 AM

But doing video transcode in Workers is not economical in Workers rn, hence why Stream exists

1984 Ford Laser•3/6/25, 9:28 AM

yeah thats the big CF draw, no egress

Voxus•3/6/25, 9:28 AM

Also when I looked into the CF pricing, it does say no egress, but cost for infrequent storage may apply?

Voxus•3/6/25, 9:29 AM

but it never says what that actually looks like

1984 Ford Laser•3/6/25, 9:29 AM

Yeah basically dont use the IA tier in R2
