I took a look at a few videos and they worked just fine even with pre-fetch enabled. Is there a particular video on that site that you can reliably cause to fail?
Theoretically, pre-fetching failing should be transparent and when the request is made for real it'll go through. I'm guessing that the pre-fetch being blocked is somehow prevent the real request from going through still.

All those worked for me, though, I am on macOS. Also, it seems like these all loaded mp4s for me. Is it loading HLS for you?

[gkatsev]

I'll try and check it out on a win10 machine.

[gkatsev]

Just tried on a win10 machine and still couldn't reproduce, unfortunately.

[T4eus]

I will investigate more, maybe is something related just to me

[gkatsev]

Maybe another extension as well? Try disabling all other extensions.

Let us know.

[T4eus]

I don't have any other, just UBO, I think the players loads before the video source, and get a error, running ping I get 200ms of latency, what you think?

thanks for attention

I tried thottling bandwidth and it made no difference for me: some videos load, others do not. The ones that do not are simply 403 responses, likely because the You Tube CDN URLs they are scraping expire.

[gkatsev]

Based on iv-org/invidious#161 (comment), it's possible that this is a googlevideo redirect issue and not something we can do anything about

[T4eus]

but if I use firefox default player, I don't get the error.
if I open the video source on other tab and wait the redirect, I can reload the invidio.us page and it will work.

this problem don't occurs on chrome, all videos plays well.

this fail specifically on the videojs player at firefox,
if get the redirect on external tab, and retry videojs player, it works.

[gkatsev]

Unfortunately, I'm not really sure if there's anything we can do here. URLs are transparent to us and mp4 loading is handled directly by the browser.
