hey - does anyone else also run into the issue of stream starting to get problems when you add around ~15 viewers when streaming? basically we're running into the issue of video getting stuck and needing to refresh the page whenever that happens, and it seems to only happen when we go above a certain load limit - and if so, anyone have any advice here? unfortunately since its in beta we cant see any metrics

and its not an issue with streaming out as that is fine with OBS, nothing dropped on that side

1984 Ford Laser•12/4/25, 8:40 PM

There shouldn't be an issue here that relates to the platform, can you reproduce this across different users/devices?

Penguinius•12/5/25, 7:33 AM

thank you for responding!

if you mean from end user side, then yep - could be reprod both from one device (where we put several streams running when trying to debug this - after adding more than 5, some of the streams started to get stuck) as well as from around 20-30 end-users who were in different networks (and ISPs) in the same country - who were all running just a single instance of the stream to their own device

near as i can tell from documentation and publicly available info, it shouldnt be a p2p sharing issue as well even though webrtc is generally meant to be that sort of thing, but it looks like for cloudflare stream product, cf network and servers do the heavy lifting, so to speak, and given the beefy hardware and network (and extremely small amount of people being streamed to) involved, this shouldnt be a product limitation - especially since we even tried pulling the resolution down to 720p, but that didnt make much of.a difference either

though since everyone is in the same country, most probably everyone is using the cf datacentre in tallinn, estonia, both for ingress and egress - but id like to imagine that shouldnt make much of a difference

so im trying to understand what might be happening, and if we can get around this issue - is there any way to enable metrics and logging? by default theyre disabled and couldnt find a way to enable them - figured its because its technically in beta as a product, but perhaps theres away regardless

in browser inspector we occasionally get 404 for get request to stream url/key, but that happens even when stream is running fine, so it probably handles occasional cuts just fine, but at some point it gets stuck and page needs to be reloaded

To sanity check, what are you streaming from?

Penguinius•12/5/25, 8:54 AM

yea shouldve specified before, but yea doubt this is the bottleneck

panasonic S9 -> m2 pro 18gig ram + OBS -> 100mbit uplink
and cf datacentre is in the same city we are streaming from (tallinn)

1984 Ford Laser•12/5/25, 10:18 AM

What are your OBS encode settings? I find that 99% of the time, that's the issue

Mehdi-Hp•12/8/25, 4:58 PM

Hi team.

I have a question about streams and live streams.

I'm in the web environment and I need to upload a video as I record it. I first tried TUS, but Cloudflare doesn't support Upload-Defer-Length: 1Upload-Defer-Length: 1 like the official TUS does.

Then I tried live streams, but the issue is, Cloudflare doesn't create recordings for those made with WebRTC.

So, the only option left seems to be uploading multipart to R2 and using a service to create the stream later.

I want to double-check: Is there no way to use streams or TUS for this?

MMehdi-Hp Hi team. I have a question about streams and live streams. I'm in the web envi...

1984 Ford Laser•12/8/25, 10:48 PM

You can push videos from R2 to Stream

1984 Ford Laser•12/8/25, 10:50 PM

You could also send WebRTC to RealtimeKit which can output RTMP and send it to Stream via RTMP

11984 Ford Laser You can push videos from R2 to Stream

Mehdi-Hp•12/9/25, 9:10 AM

Is this something that Cloudflare does, or just using a Worker?

Correct

Mikey Beats•12/21/25, 10:19 PM

thank you @1984 Ford Laser one other question. the "5,000 minutes of video delivered per month" is that the minutes I stream to the server or is that watched, like say 10 viewers watch for 10 minutes each live, is that 100 minutes spent towards the 5,000?

1984 Ford Laser•12/21/25, 10:19 PM

Thats the viewers watching, 100mins towards 5k

Mikey Beats•12/21/25, 10:19 PM

ok. thank you!

Mikey Beats•12/21/25, 10:45 PM

One last question i think.

Do you recommend Apple hardware or x264 for video encoder?

1984 Ford Laser•12/21/25, 10:46 PM

Apple hardware for sure

Mikey Beats•12/21/25, 10:46 PM

thanks!

Mikey Beats•12/21/25, 11:29 PM

oh i do have one other question.. If I am streaming, but have 0 views, does that still count as delivered minutes for the minutes with 0 views but i'm still live?

1984 Ford Laser•12/22/25, 12:19 AM

If there is 0 viewers it wont incur any minutes delivered. But even monitoring your own stream in the backend will count as a viewer fyi

Mikey Beats•12/22/25, 12:26 AM

ok. thank you. gonna order it and give it a try

Shanu•12/22/25, 4:21 PM

Hello guys, I’m planning to use Cloudflare Stream’s API to upload videos and let them transcode to H.264/AAC/1080p. I then want to download that encoded MP4 from Stream and store it in R2. I’ll serve that MP4 via a Worker, not via Stream’s player or HLS/DASH. I’m only using Stream as an encoder, then serving the MP4 from R2. Is this “Stream as encoder → download MP4 → serve from R2” pattern allowed to use or will it be risky as per cloudflare policies. Thank you.

1984 Ford Laser•12/22/25, 8:47 PM

I'm 99% sure that this pattern is against ToS, if you use Stream to encode then you need it to deliver too

Shanu•12/22/25, 11:51 PM

I observe this from ToS "Customers can serve video and other large files using the CDN so long as that content is hosted by a Cloudflare service like Stream, Images, or R2." . Also I noticed that streams have an api for downloading content. This makes me think about using it as a transcoder service.

1984 Ford Laser•12/22/25, 11:56 PM

I can't find any exact docs/tos reference to support what I'm saying, but I swear I remember reading something from CF that using Stream basically as a transcode/download service only is not allowed. But I personally use the service in a similar way, I guess your mileage may vary

Subject: How to force Cloudflare Stream Iframe to fill container (Object-fit: cover) without losing quality?
Body: Hi everyone,

I'm building a mobile video feed (TikTok style) using Cloudflare Stream embedded via iframe. My container is responsive (100vw / 100vh), but I'm struggling with two main issues:

Aspect Ratio & Letterboxing: Even with fit=cover in the URL and object-fit: cover in my CSS, the video often shows black bars (letterboxing) or refuses to fill the entire height of the viewport on different mobile devices.

Quality Degradation: When I try to force the iframe to stretch using transform: scale() or by setting large dimensions, Cloudflare's adaptive bitrate seems to downscale the resolution, resulting in a blurry video.

Current Code:

HTML

<div class="video-container" style="width: 100vw; height: 100vh; overflow: hidden; position: relative;">
<iframe
src="https://customer-ID.cloudflarestream.com/VIDEO_ID/iframe?fit=cover&preload=true"
style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; object-fit: cover;"
allow="autoplay; encrypted-media;"
allowfullscreen>
</iframe>
</div>
What I've tried:

Adding &stretch=true and &fit=cover to the iframe URL.

Using object-fit: cover on the iframe and the container.

Attempting to use the Cloudflare Stream SDK (<stream> tag), but had issues with initialization in a dynamic AJAX feed.

Question: Is there a reliable way to make the Cloudflare Stream player fill the entire screen (cropping the sides if necessary) while forcing it to maintain high resolution? Is there a specific CSS trick or SDK configuration I'm missing to achieve a true "Vertical Fullscreen" effect?

Thanks for the help!
