Hello - streaming question about WHIP/WHEP and Cloudflare's implementation of it - specifically, has anything changed in the past 1-2 months? I've been working on a project in which a Docker container streams audio via

gstreamer

gstreamer

gstreamer

gstreamer to a WHIP endpoint on Stream, and this was working successfully; however, returning to it in the past week or two, and nothing appears to connect. Obviously there are loads of places we could be having issues - the gstreamer Rust plugins, networking issues, etc - but just trying to pin down if there's anything at the CF end that has changed.

I've tried using with https://github.com/meetecho/simple-whip-client/tree/main, and I get a 400 error from cloudflare with the sample "connect and stream test video/audio":

This is also a GStreamer-based project. so: my gut sense is that either something has changed in GStreamer, that means it now leeds to Bad Requests on the trickle spec, or something has changed at Cloudflare's end that means these requests are now 400ing.

I mention it's specifically GStreamer related, because other clients - eg OBS - still stream to WHIP just fine.

So I'm building an application, and for testing, I have created a looping live stream from FFmpeg on my server and am publishing it to a live input. does anyone know How will I be billed for it as it forces me to record it?

1984 Ford Laser•7/13/25, 4:48 AM

if no one views the stream then you will only be charged for the storage used

1984 Ford Laser•7/13/25, 4:50 AM

If its a 24/7 stream, I'd set up a cron Worker to stop/restart the stream every x hours. Live stream recordings have a max segment length of 7200 so Im not sure if you'll have issues running a super long continuous stream

Has Cloudflare Stream degraded to being unusable over the past 2 months? I have changed nothing on my end but now get constant buffering and random repeated key frames. Even after having my broadband connection investigated and found to have no dropouts or jitter, the same issues persist when using Cloudflare stream. Even with new modem/router. Way overdue updates in anycase here in Cloudflare Stream including option to live stream only with no automated recording function as I don't require recording of my streams. And if anyone ever knew what the Cloudflare RTMP or SRT push settings are, I would be eternally grateful instead of playing what is now the pointless guessing games when it comes to Cloudflare stream push settings.

I was able to stream

42c01f

42c01f

42c01f

42c01f in OBS via WebRTC.

For what it's worth, to stream the profile

42c01f

42c01f

42c01f

42c01f, set the video encoder to x264 with custom options

profile=baseline level=3.1 ref=1 keyint=60 scenecut=0 bframes=0

profile=baseline level=3.1 ref=1 keyint=60 scenecut=0 bframes=0

profile=baseline level=3.1 ref=1 keyint=60 scenecut=0 bframes=0

profile=baseline level=3.1 ref=1 keyint=60 scenecut=0 bframes=0

Thanks for the pointer! Now I can eliminate the codec as the source of the issue

Nah I'm 99% sure the Images Transformation binding is separate to Video/Media Transformations. You could do a fetch() within a Worker to the same URL that you would use to generate the transformed video, that might just speed up access slightly but that's all

Deanna•7/28/25, 4:40 PM

@Meisa you won't be able to upload more images/videos once you hit your storage limit. you can always modify your subscription to purchase storage.

delivery is usage-based, so you'll be charged for additional usage beyond the delivery volume included in the bundled plans

hello guys, is this information relevant and still valid ? "All Cloudflare customers with a Biz or Pro domain will be able to store up to 100 minutes of video content and deliver up to 10,000 minutes of video content each month at no additional cost"

If i buy CDN Pro plan is there included 10 000 minutes of video streaming in that price 20 dolllars monthly for Cloudflare PRO service ?

TLDR: Does WebRTC Cloudflare Stream support h264 profile 42c01f? Hey Stream devs, I'm using WebRT
