Hi. I'm new to Cloudflare Stream and I'm trying to use live input. If I set

Live Playback and Recording to false, is it still possible to view the live video?
Right now, the dashboard shows the live status as

Hi, I'm using streams an images and I'm having problem with sticky cache for images for variants. I feel like this is a recent change when variants keep serving old content, even if the original image has been deleted from CF. My limited human brain tells me that if a image is deleted the variant cache should be invalidated, which does not seem to be the case. Does anyone have any insight into this?

Stone•8/11/25, 2:30 PM

Sorry about posting it in streams. I tired general help and I'm at a loss here. Would really like to keep using images but this is a big roadblock for me... and it used to work fine before

Has anyone seen "Failed to determine file size" when using Media Transform? We started getting this error for 100% of our Azure Blob Storage videos, same video uploaded to R2 works fine, video is publicly accessible, configuration worked a couple months ago and just started failing a few weeks ago. Images in the same blob store transform just fine.

I'm totally stumped, no idea how to even start debugging.

You could re-stream to another platform to check?

1984 Ford Laser•8/11/25, 11:38 PM

You would probably need to manually invalidate your cache. #workers-and-pages-discussions would probably be the best place to ask about this, I'm not sure there's much control over caching from within Images itself

1984 Ford Laser•8/11/25, 11:39 PM

Is it the same video that's failing? Even if you re-encode it into a different format

1984 Ford Laser•8/11/25, 11:39 PM

Also are you abiding by limitations for Media Transforms

tom•8/11/25, 11:40 PM

It's all videos hosted on Azure Blob Storage. The same video works if hosted on R2 (we actually upload the exact same source to both platforms, so guaranteed identical).

tom•8/11/25, 11:41 PM

And yeah, same URL construction between Azure and R2, doesn't change if I monkey with the params to be for sure under e.g. the duration limit.

1984 Ford Laser•8/11/25, 11:42 PM

And it used to work with Azure and doesnt anymore?

tom•8/11/25, 11:43 PM

Correct, last verified success was in early June, we don't have metrics on when it stopped working unfortunately.

tom•8/11/25, 11:43 PM

Also tested across a couple of different Azure Storage accounts

1984 Ford Laser•8/11/25, 11:46 PM

Just for completeness sake, have you tested with the video that worked in June?

1984 Ford Laser•8/11/25, 11:47 PM

Have you set up Specified Origins in your Media Transform settings?

tom•8/11/25, 11:47 PM

Yeah, same deal.

My hail mary guess is that it has something to do with Azure not returning Accept-range: bytesAccept-range: bytes header by default, even though it does support streaming, and Media Transformations relying on that header now

tom•8/11/25, 11:48 PM

And yeah, no changes to the origin config, triple checked it, same behavior if I remove the origin restrictions and allow all origins

1984 Ford Laser•8/11/25, 11:48 PM

Yeah okay thats an odd one. Sorry I cant be more help, only suggestion from here is just use R2 totally

tom•8/11/25, 11:49 PM

Yeah we are actually doing that (part of the June work was to duplicate uploads between both as we progressively migrate away from Azure Storage) but still need it for old stuff

tom•8/11/25, 11:49 PM

Thanks anyway!

I've definitely had some viewers watching from China so I guess they kinda counts?

Any problems with watching from China that you encountered?

McSneaky•8/15/25, 8:05 AM

When I upload 580x400 16.6MB video to Cloudflare stream and then use "Direct download" to pull it down again I get 522x360 800kb video. There's quite a bit of quality reduction

Same quality reduction is when I stream it at highest HSL quality

Anyone else seen something similar? Are then any quality flags or something that can change?

McSneaky•8/15/25, 8:22 AM

Oke, found it. CF Stream turns everything to lowest step
470x470px video will be turned to 360x360

1000x1000px video will be turned to 720p etc

Since 470x470 isn't enuf to have 480p video, so it gets turned down to lower step

Steps seem to be
240p, 360p, 480p, 720p 1080p (and maybe 4k?)

Does this happen with a specific video? Decoding error is odd

1984 Ford Laser•8/17/25, 8:08 AM

You can't use the HTTP API to do this

1984 Ford Laser•8/17/25, 8:08 AM

Use tus or upload videos elsewhere and provide the MP4 link (I use R2 for this sometimes)

1984 Ford Laser•8/17/25, 8:09 AM

https://developers.cloudflare.com/stream/uploading-videos/upload-video-file/

Really helps if you read the documentation
