I am unable to reproduce. I put together this simple test case:

I don't see the problem that you're observing on 57.0.2970.0 (Official Build) dev (64-bit). Could you help me get this right?

In your stackoverflow question you can see that the subsequent requests are getting a 304 (Not Modified) status response. So this is a caching issue. Can you provide a network trace? 

See https://sites.google.com/a/chromium.org/dev/for-testers/providing-network-details

Likely this is a cache freshness issue. That you are indicating the video's lifetime is something expired or something that must be re-validated.

Unfortunately can't find the commit with the video and can't test it again, but dglazarov demo is working fine, without making new requests. Maybe my test was on some previous version and didn't notice the update.

Reporter can't reproduce and can't provide a network trace and the issue works correctly in a example dglazarov wrote.

It looks like this bug is back. Please see the example and attached screenshot below. "Disable Cache" is unchecked but the video is downloaded over and over.

This issue is noticed on 56.0.2924.87 and 57.0.2987.74 beta (64-bit) Versions. 

I am pretty sure that the issue is with the file size. The small video (less than 5MB) file plays without re-download. Is it intended?

I am finding the same. Videos over 5mb send out partial content requests on loops. I am on version 56.0.2924.87. This is a costly issue as a website left open can rack up 100s of gigs worth of video requests. Is there any solution?

 

That is my testing site after 35 minutes… Chrome 56.0.2924.87 (MacOS). I can not provide a link, it will probably ruin my hosting :( Honestly with this bug I can't publish my site to production.

Anyway the bug is reproducible (for me) on https://www.strv.com

I have updated to ver 57.0.2987.98 and I have my video under 5mb, and it is still requesting the video every loop (206) BUT it is at least pulling from disk cache now and no longer pulling from server.

Can anyone else comment on if it works with videos over 5mb on ver 57.0 +

Nick, 

Here is one example with 22 MB video. In  57.0.2987.98 beta (64-bit) I  can confirm if it requesting from disk cache.  

Is this fix applies to other media like images too?

Great! It was re-downloading every loop in 56.0.2924.87 (64bit), but after upgrading Chrome to 57.0.2987.98 (64bit) no more re-downloading! ('from disk cache' in every loop).

I have the same problem with a newer version of Chromium. My app is build in a framework (EmberJS). It keeps requesting the same video even when redirected to another page (it's gone from DOM but still requesting (already resolved)).

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.79 Safari/537.36

Video specs:
- 00:00:17 
- 64.1 MB
- 4K

- Disable Cache is unchecked
