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: 1

Upload-Defer-Length: 1

Upload-Defer-Length: 1

Upload-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?

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

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

In the Video URL box here, enter the video's URL on R2, whether that be public or custom domain

Which can also be achieved with this API request

That's helpful. Thanks

I see that simulcasting is not yet supported with web-rtc.
What would be the most practical way to deploy a feature for my application that allows users to multistreaming to different social platforms from their browser ?

What hardware/software are you using to send to Stream?

1984 Ford Laser•12/21/25, 10:12 PM

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

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.

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

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!
