I was playing around with the DVR, with an hls link which was streaming past 7 hours, but when I add the dvrEnabled=true it doesnt work why? I enabled the recording and the videos are there.

Another issue, when the stream loses connectivity , the recoreded videos is stopped and a new one is created does the DVR combine them by default if it works?

DVR for Live · Cloudflare Stream docs

Stream Live supports "DVR mode" on an opt-in basis to allow viewers to rewind,
resume, and fast-forward a live broadcast. To enable DVR mode, add the
dvrEnabled=true query parameter to the Stream Player embed source or the HLS
manifest URL.

You need to read the docs on the DVR feature (below isn't directly copied from docs, but the page does explain things)

Manifests are limited to 7200 segments, so depending on your keyframe interval you will probably hit that limit after a number of hours
The DVR won't combine the different streams together. There is a small timeout period where the stream will wait for a reconnection before splitting into a new stream

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:

Sub-second latency live streaming (using WHIP) and playback (using WHEP) to unlimited concurrent viewers.

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

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?
