We use Stream with Signed URLs required for our videos. I just tested out the new AI-generated captions feature, but found that the generated captions didn't display anything during video playback. When I downloaded the caption file to inspect it, I saw that the file contents were: "401 unauthorized". Do I need to do something special to generate captions for these videos? I didn't see any mention of the AI captions being incompatible with Signed URLs in the documentation at https://developers.cloudflare.com/stream/edit-videos/adding-captions/#limitations so wanted to ask here.

This should work, I just tested to confirm and everything worked as expected on my end. Are you able to reproduce the captions not displaying during playback consistently? I would try deleting the generated captions and generating them again. They do take a little bit of time to finish generating depending on the length of the video. If you can reproduce this consistently, could you DM me a video UID where you're seeing this issue?

If you're trying to retrieve the captions on a video with Signed URLs enabled, you will need to use either the v4 API (documented here) or via https://customer-<CODE>.cloudflarestream.com/<TOKEN>/captions/enhttps://customer-<CODE>.cloudflarestream.com/<TOKEN>/captions/en. https://customer-<CODE>.cloudflarestream.com/<VIDEO_UID>/captions/enhttps://customer-<CODE>.cloudflarestream.com/<VIDEO_UID>/captions/en will return a 401 with signed URLs enabled.

The API works, but Stream web UI doesn't work for videos requiring Signed URLs: You can create a new AI-generated English caption, you can wait for it to be in the "Ready" state and then "Download" from the "..." menu. But the downloaded en.vtten.vtt file just contains text "401 unauthorized".

Captions aside, the Stream UI is challenging to use for videos that require signed URLs. There are no previews or poster images visible, so navigation is limited by either filename or record-keeping in an external system.

1984 Ford Laser•8/22/24, 11:22 PM

Super minor thing, but I'd love to be able to open the Live Inputs in a new tab, instead of one by one, in the same way I can do so with the Videos. Yes yes I know I should be using the API to do stuff

While a stream is live, is it possible to load all HLS segments? Or am I just dumb :lul:

PJ•8/27/24, 2:01 AM

Hey Folks, I'm using CF Workers with Bun/hono/Drizzle/Lucia/D1 along with Stream. I'm trying to use TUS protocol in a React component to upload videos using this library (https://github.com/kqito/use-tus). I'm having a hard time to include my session Cookie on the initial tus request to CF worker endpoint protected by Lucia Auth - which will obtain the tus Location header. as response TUS works very well without the protected endpoint/without auth. It breaks when I make the CF worker endpoint protected, because react frontend isn't passing the cookie. Do you folks have any sample react code with tus implementation. In the Stream documentation, the code example uses vanilla js with Uppy library. I'm trying to implement tus using React.

ElliotD•8/27/24, 6:46 PM

Hey all, I'm trying to find a provider to serve HLS VoD content and CF Stream looks promising. One caveat is that I need my HLS content to have multi-channel audio encoded as separate streams. So for example:

video.m3u8video.m3u8 audio1.m3u8audio1.m3u8 audio2.m3u8audio2.m3u8

And a master master.m3u8master.m3u8 to sync everything.

I didn't see anything in the documentation about multi-channel / multiple-stream audio. Is this something that's supported?

agoddard•8/27/24, 11:57 PM

is anyone using Uppy with TUS uploads for stream direct creator uploads? If I use the tus-upload python CLI client, it works fine - if I use the sample code from the CloudFlare docs in JS, every HTTP PATCH request fails. This is the example code I am using https://developers.cloudflare.com/stream/uploading-videos/direct-creator-uploads/#step-2-use-this-api-endpoint-with-your-tus-client

Is anyone else using WebRTC? Do you experience intermittent video stream while audio is fine? I have tried everything, LTE vs WIFI, tranceiver parameters (maxBitrate, maxFramerate), starting with just the basic <video> element on the page. It was working better a couple days ago so maybe it is CloudFlare servers?

Hi, is there any plan to integrate R2 with streams so that video files can be uploaded to a bucket and then used as a source for stream? I would like to use my own upload infrastructure, which also depends on the TUS protocol, but which can upload any data to R2. I also want to keep the original video file in my R2 bucket instead of uploading all the files to stream.

I found the reason. I tried to stream via WHIP, I wanted to receive it as HLS, so I tried to find the stream in the cloudflare dashboard. But the stream didn’t even start there. Since this is beta, cloudflare can only stream via WHEP at this stage. We just had to read the instructions to the end...:NotLikeThis:

1984 Ford Laser•9/13/24, 7:50 AM

Anecdotal evidence, I recently moved ~150k mins/month streaming from a platform that charged per GB to CF Stream and I have seen significant cost savings. Like from several hundred a month (with massive peaks during some major events) to not even a couple hundred a month. Before when we were seeing those outlying peaks, we were out of pocket 1K+ per week this happened, now its maybe a few hundred

1984 Ford Laser•9/13/24, 7:51 AM

I dont have detailed analytics of the bitrates streamed and stuff, but I can say that this pricing model has been beneficial for us in every way

gtech9451•9/13/24, 12:52 PM

Any updates on the WebRTC Beta being ready to release? We need the capacity to go live from our browser/app; without a RTMPS/SRT.

The pain point right now is the lack of Recording/Replay under the WebRTC implementation

1984 Ford Laser•9/13/24, 10:48 PM

I'm also looking forward to WebRTC-to-RTMP which was planned at some stage I believe. I have some workflows that will save me major hassle if that is implemented

Hey guys, i'm using the stream & images product but for some reason i have been getting double charged for my usage over the last 4 months and have paid over $1,000 to cloudflare that I shouldn't have. I have reached out to the support team multiple times but havent gotten any help. They usually respond asking a question, then I answer their email but after that its radio silence. I am really lost for what to do. I am running a small business and we really cant afford this double charge every month. Is there any help I can get here?

Hi,

I'm planning to write a technical article about implementing Cloudflare Stream at our company. Our experience with the Cloudflare Stream service has been excellent, and since there are few case studies in Japan, I'd like to share ours.

I have a question: Is it acceptable to include screenshots of the dashboard in the article? Specifically, since we haven't received any special accommodations regarding pricing, we believe we're only sharing publicly available information.

Thank you!

Is anyone here able to trigger a Cloudflare Stream video via javascript to player.play();player.play(); or player.pause();player.pause();

I have a button on my webpage that will display an overlay with the video. All the javascript calls and flow are correct, but when calling play()play() or pause()pause() they just do nothing.

I'm following the example documented here: https://developers.cloudflare.com/stream/viewing-videos/using-the-stream-player/using-the-player-api/

Anyone else figure this out? Am I missing something obvious here?

Apparently, this is a case where, once again, after hours of messing with this, I figured it out minutes after posting here...

It appears that pause()pause() and play()play() ONLY work if you have autoplay=trueautoplay=true on the iframe source.

Hopefully this helps someone else.

Does Trickle ICE currently work with WebRTC? I'm getting:
"WHIPClient Endpoint does not support Trickle ICE"

leesus•9/18/24, 6:49 PM

Is there an issue currently with webhook notifications? I have had a webhook set up for around a year, pointing at a worker, which has been fine up to this point. The past few days users have been uploading videos, and the worker is not being called via webhook - the videos are uploaded to stream ok and are ready to play. There's nowhere I can see in the UI with event logs for webhook events so I can't see what the issue could be and why it would randomly start failing to send.

I've verified its not an issue with the worker, I can call it manually, and I've checked the logs and there are no requests at all, they're not even being sent from Stream.
