Yes. Things look okay in the API. Here's what I see after manually-uploading caption:

[
  {
    "result": [
      {
        "language": "en",
        "label": "English",
        "generated": false,
        "status": "ready"
      }
    ],
    "success": true,
    "errors": [],
    "messages": []
  }
]

[
  {
    "result": [
      {
        "language": "en",
        "label": "English",
        "generated": false,
        "status": "ready"
      }
    ],
    "success": true,
    "errors": [],
    "messages": []
  }
]

Did you manually add that file before/after deleting the generated one? I'm not sure what's happening but wanna nail down what could cause it

1984 Ford LaserOP•4/28/25, 11:48 PM

Just out of curiosity, does the same thing happen when trying to upload that caption to another language?

ari•4/29/25, 12:02 AM

Issue only happens if an AI-generated caption was generated first. If the first upload was manually-generated, everything is fine.

ari•4/29/25, 12:04 AM

Can repro this outside of my video player, just by switching captions and visiting https://customer-....cloudflarestream.com/.../captions/en in a browser. Seems like there's a 1-2 minute (cache-related?) delay between when caption status shows as "Ready" and when the change is reflected in the browser, but setting aside the display, the issue is definitely replicable there.

The live stream still stops whenever the signed token changes

ari•4/29/25, 12:10 AM

Related feature request: It would have been easier/faster to isolate the bug I was running into if the Stream video player embedded on the Captions page included a menu option to display closed captions.

1984 Ford LaserOP•4/29/25, 12:49 AM

That feels like such a Cloudflare oversight that the page for captions doesn't have a captions option for viewing

Hello everybody. I bought stream package and I have a question. Is there a way for rejecting abuse watches of our videos? For example someone can open videos continuously and bill will increase. Is there a way for protecting this?

You would need to create your own flow of some sort. Creating signed tokens on your frontend or something

Neo•4/29/25, 10:08 AM

I see

any knows the best way for stream player to handle when the signed tokens get refreshed, my player stops every time for like a 1 sec or 2

Hi, I’m encountering the error “The video duration exceeded the constraint set by the account holder” when uploading a video to Cloudflare Stream, even though the video is short (around 30 seconds). I’ve correctly set the upload metadata and the video is encoded with filetype: "video/mp4; codecs=avc1.42000a,mp4a.40.2". Could this be an issue with the encoding or is there a hidden duration constraint that I might be missing?

Any help would be greatly appreciated!

Mladenovic13•5/2/25, 10:05 PM

We never had this problem until iOS 18.4.1

1984 Ford LaserOP•5/2/25, 10:09 PM

So this issue only happens on iOS 18.4.1? You're uploading on the device, or just recording the video?

Mladenovic13•5/2/25, 10:15 PM

We record the video on the device using the MediaRecorder API, and then upload it to Cloudflare via the TUS client.

Mladenovic13•5/2/25, 10:17 PM

The error doesn’t occur with every video, but rather in about 20-30% of cases

Can we get these new UI updates pushed to the Stream dash as well? I wanna middle click my live inputs!

JJon M.Does anyone know when WebRTC will support recording?

1984 Ford LaserOP•5/3/25, 12:37 PM

RealtimeKit, once available, should apparently support this

No? Did you read the docs page on WebRTC streaming, specifically the Limitations section? https://developers.cloudflare.com/stream/webrtc-beta/#limitations-while-in-beta

1984 Ford LaserOP•5/9/25, 10:59 PM

Okay? You're free to use another platform if this isn't good enough for you.

Is Stream linked to R2 in the backend at all? Like when I'm uploading a video in the UI, is that actually going to an R2 bucket behind the scenes? Wanna ascertain if there are upload speed limits for an account due to this

Gabriel Francisco•5/10/25, 4:14 PM

Is that possible to know the video aspect ration using the cloudflare player? I would like to resize the parent of the iframe based on that. The runtime API doesn't have anything to help me on this, but is that any other way?

They've disclosed before in incidient reports for R2 (like when they rotated creds and caused r2 to fail), that Stream uses R2:
https://blog.cloudflare.com/cloudflare-incident-march-21-2025/

All (100% of) uploads failed during the primary incident window. Successful Stream video segment delivery dropped to 94%. Viewers may have seen video stalls every minute or so, although actual impact would have varied.
