I can't seem to download some captions from the API and Dashboard. The captions show up in the video, but when downloading from the dashboard I get an empty file, and from the API I get a 500 error.

They are captions I uploaded a while ago, problem is I lost the original file and now I'm trying to download the file in Cloudflare but it comes empty.

does anybody know if cloudflare SRT supports multi track audio? I think i tried it and it doesnt seem to work but I dont know if its on my end of if it just isnt supported in cloudflare stream

Nah not possible, this is a feature I would use plenty if it was available

This is for a mobile app.

Josh - NEXX•9/19/25, 12:55 AM

It’s serving as a panic button for potential victims of crimes.

Josh - NEXX•9/19/25, 12:55 AM

So the idea is to have the potential incident streamed to a control center.

Josh - NEXX•9/19/25, 12:56 AM

While giving real time video and also having it recorded if needs be for them to enter evidence.

Currently you can only get live viewer numbers via API. I'm hoping they make all of the metrics/events from live inputs available eventually

Hi, is there any plan for custom playback domain for Cloudflare Stream? (I mean the one used for serving videos not for ingestion)

javery•9/23/25, 8:24 AM

Looking at setting up a small streaming app that allows users to register and get a streaming key that they can then use for live streaming, but we do the heavy lifting and automagically create the streaming endpoints on Cloudflare. We're looking at a few different providers but we're already using stream for uploading existing videos, and with the clipping already built in I'm hoping that CF can handle all our needs.

TL;DR - LiveU SRT flowing through Cloudflare Stream, SRT playback works but customer m3u8 and recording does not exist???

Wondering if anyone has a similar experience to me....
I know LiveU (Solo + LRT) is the cause of many a woe with its lack of reporting errors, no feedback on connection status, not accepting rtmp parameters, etc. but I have a specific issue I'm looking at.

I decided to experiment with Cloudflare Stream as a gateway for two remote LiveU Solos with LRT to SRT to provide a single hop SRT connection to a remote vMix producer.

Once dialled in, the two LiveUs stay in sync all day long. Playback via the Cloudflare SRT output. No problem at all. However I noticed that the camera sessions weren't being recorded! 2 seconds or 'problem encoding'. Two four hour streams that cloudflare doesnt seem to think existed but the end to end was uninterrupted.

Last night I used a produced output direct into cloudflare stream via LRT + SRT and the same thing - it was there, it was readable over SRT playback, but no event recording and crucially this time - no customer side m3u8 playback.

I asked the producer to switch over to RTMPS output from LiveU and it was fine - absolutely normal.

Anybody else experienced anything like this, and know of any fix? I actually dont mind these long running CAMERA sessions not being recorded, but the Production TX not being recorded could be problematic.

If anyone from CF Stream team is here, sample videoIDs are:

davidinfinity•9/24/25, 9:31 AM

like 2 seconds, 2 seconds, error, error, error, 2 seconds. with SRT. (but the SRT playback FROM cloudflare on that same INPUT channel is uninterrupted)

RTMPS is absolutely normal

1984 Ford Laser•9/24/25, 9:31 AM

Yeah okay weird

1984 Ford Laser•9/24/25, 9:31 AM

Lemme do a test tomorrow with SRT and see if I can reproduce

1984 Ford Laser•9/24/25, 9:33 AM

Does vMix send straight to your endpoint? I use an additional live input and restreaming to record both my camera inputs and mixed outputs

1984 Ford Laser•9/24/25, 9:33 AM

I'm actually not sure if my unit has LRT enabled as we don't use it often

1984 Ford Laser•9/24/25, 9:33 AM

Will check in morning

davidinfinity•9/24/25, 9:34 AM

Almost always use vMix direct to CF; but in this situation its multi cam remote production i had to solve; and then last night, production from a remote location they used liveu to balance bonding -- and same issue. So, all LiveU LRT SRT

davidinfinity•9/24/25, 9:34 AM

IIRC can only use SRT with LRT enabled?

You have to do it video by video, and updating video details is a POST request

davidinfinity•9/26/25, 9:07 PM

were you able to have a look at this? I've had another stream this evening, a two different liveus from a different location - same thing, 2secs or 22secs and 'error' on the pre-event and event connections despite signals routing through cloudflare, out the other end to vmix producer for three hours straight. bizarre!

JayTheDeveloper•9/27/25, 1:50 AM

1984 Ford Laser•9/27/25, 2:03 AM

I can't seem to get SRT working on my unit at all, no LRT. I can't really purchase LRT just for this test cos the unit won't be getting used for events for the next 6 months so can't really justify the cost

any reason why you can't go RTMP from LiveU to CF, then SRT from CF to vMix?

1984 Ford Laser•9/27/25, 2:14 AM

Is there any plan to expand Media Transformations to include functionality like stitching multiple videos together? I'd also love to be able to export MOVs with a transparency layer. The plan is to take clips produced by Live Instant Clipping and add top/tail clips, and figured doing that natively on-platform would be faster than either writing a Worker or moving off-platform entirely

On the topic of feature requests, I'd love to be able to add images/videos as overlays to live streams. We can apply watermarks to uploaded videos, but adding that as a live feature would be sick. Customizable stream delay would also be cool, like if I have multiple RTMP re-streams, would be cool to be able to define different delays on each output

I can't seem to download some captions from the API and Dashboard. The captions show up in the video
