Hello everyone, i want to ask about download url. Because i am using aws lambda to create backend server-side so that i cannot wait for the time of API response. I have heard about webhook but it is not have any doc about download url notification. Is there any solution for me. Because i really don't know how to creato webhook for download url and then it will send to me a notification.

There isn't a way natively to get a webhook when a download URL is ready. When you receive the video upload webhook, you could setup some sort of process to poll the video's status until the link is ready or something

When generating tokens for videos, is it required to specify access rules and/or supported regions?

Since there wasn’t an easy way to play WHEP with Stream’s WebRTC,
I wrote a small Go app that pulls the video and plays it with ffplay.
Might be useful for others:

Anyone know if we can put html layer inside the studio of realtime meeting? Just like how streamyard does?

Is there some sort of cap on how far HLS DVR playback can go?
I know m3u8 manifests have the 7200 segment limit, but we're not anywhere close to that. I know it's not time-based because some will go for 4+ hours without issue, while others can start losing the first 30+ minutes of the stream as soon as 70 minutes in. And I don't think it's bytes because I've had issues with some small 480p files much smaller than our normal ones that are fine.
Using OBS + rtmps, but have a couple dozen PC sources so not everyone's encoder settings are the same.
Have also tried pushing some pre-recorded mp4s live via ffmpeg/rtmps and have had similar inconsistencies with those.
We don't use dash and I don't know if it's supposed to support DVR but I threw ?dvrEnabled=true on one and it also only went back to the same spot.

If there's not a retention cap, then it has to be something with the encoding but I haven't been able to figure out the commonalities between the ones that have issues. Any ideas what could cause that?

1984 Ford Laser•8/31/25, 2:14 AM

Go to the metrics tab of one of your live inputs and check out the Upload-to-Duration ratio. Would be interesting to know if your client is sending wildly fluctuating packets. I do at least a dozen 3+ hour live streams a week, use dvrEnabled=true and don't have the issues you're describing

Can you provide an example of OBS settings that have given you issues?

claass•8/31/25, 2:32 AM

A current example, actually. Not my PC nor me streaming. Up for nearly 3 hours at this point but could only go back less than 1.5 hours.

1984 Ford Laser•8/31/25, 2:48 AM

woah that upload to duration ratio is not great at all

claass•8/31/25, 2:48 AM

Has also happened with NVENC H.264 encoder today. Need to check on the rest of their settings. But had the issue with the left picture. No issue on a different stream by same person after that, on the right.

1984 Ford Laser•8/31/25, 2:49 AM

Are you working with mobile networks or something?

11984 Ford Laser woah that upload to duration ratio is not great at all

1984 Ford Laser•8/31/25, 2:50 AM

on my end the lowest ratio I see is like 90+% and can go as high as 150%

1984 Ford Laser•8/31/25, 2:51 AM

Are these users located far away from you geographically? I wonder if general network routing could cause something like this

1984 Ford Laser•8/31/25, 2:53 AM

This is from the same stream I sent before now its been running for a while

1984 Ford Laser•8/31/25, 2:57 AM

oh your keyframe intervals also wildly fluctuate

1984 Ford Laser•8/31/25, 2:57 AM

I wonder if your users are seeing any dropped frames in OBS

1984 Ford Laser•8/31/25, 2:58 AM

x264 could totally contribute to an inconsistent encoding output

1984 Ford Laser•8/31/25, 2:58 AM

especially if the hardware is being strained in any meaningful way while doing the encoding

claass•8/31/25, 3:00 AM

Troubleshooting page
"It should be a consistent flat line below 90%. If you see an inconsistent or wavy line, or a line that is consistently above 100%, try the following troubleshooting steps:"

Admittedly they're not flat but they are under 90% most of the time, thought over 100% was potentially problematic.

Not mobile networks. Pretty spread out geographically. No dropped frames listed in OBS ever.

My guess has been it's related to keyframes/open GOP/b frames but haven't been able to pinpoint.

claass•8/31/25, 3:10 AM

My personal ones never fluctuate with NVENC, which is probably why I've not been able to recreate the issue myself through OBS.
Will have them try keyint, min-keyint, disable scenecut and maybe disable b frames. and see if we can get a constant and closed keyframe and what happens.

claass•8/31/25, 3:19 AM

Are your keyframes always constant @1984 Ford Laser ?

1984 Ford Laser•8/31/25, 3:20 AM

Direct from OBS no

1984 Ford Laser•8/31/25, 3:20 AM

But also working with mobile networks

1984 Ford Laser•8/31/25, 3:20 AM

claass•8/31/25, 3:21 AM

Still far more stable though.

1984 Ford Laser•8/31/25, 3:21 AM

yeah absolutely

claass•8/31/25, 3:21 AM

Cool. Appreciate your time and help!

1984 Ford Laser•8/31/25, 3:21 AM

No worries mate happy to help

1984 Ford Laser•8/31/25, 5:55 AM

@claass another thought I had, do you create the live inputs for your users? Live inputs use Durable Objects under the hood, so I wonder if you're creating a really far away DO instance that's causing less than ideal routing for your users. You aren't broadcasting from outback australia by chance?

claass•8/31/25, 1:09 PM

We do, will keep that in mind.
I was able to recreate the issue myself overnight (on a live input I created myself). Switched to x264 on simple mode and got this. Then did a subsequent one on advanced with keyframe = 2 (hence the big keyframe dropoff and leveling) but still had the issue again.
Retrying now with x264 options keyint=60 min-keyint=60 scenecut=0 closed-gop=1.
I'm thinking B frames are crossing GOPs. But I'm not sure that explains the issue happening for NVENC/QSV encoders since to my understanding those are supposed to be closed GOPs by default.

I think using Stream purely as an encoding service only is against ToS but don't quote me, I swear I read it somewhere

Use Media Transformations https://developers.cloudflare.com/stream/transform-videos/

Cloudflare Docs

Transform videos

You can optimize and manipulate videos stored outside of Cloudflare Stream with Media Transformations. Transformed videos and images are served from one of your zones on Cloudflare.

Using Image Transformations, it should be fine. But iirc, anything that has its own storage, requires you to serve from said storage
