Can not play youtube videoss in Firefox, Chrome or any browser except Tor.

If I download the video it will play. But, I can not play a live cam unless I use Tor.

I have had this problem for 3 years and no one can seem to figure it out.

Error is: Failed to find video url.

Thanks, Rob

Hi Rob, it's a little hard to read, but a "304" means a cached version does not need to be updated, so that is fine.

The --- status seems to indicate a request did not finish yet, either it is in process or it's going to time out.

On http://explore.org/live-cams/player/decorah-eagles-north-nest

Could you take a closer look at this line:

red square 400 qoe?event=streamingstats&fmt=244&afmt=251&cpn=M s.youtube.com

Is your Firefox sending the referrer and cookies shown in the Request Headers in my attached image?

On the bears video I get all status 200, 200 chunk_1491796023_731af1d23f.flv sjc-ucdn01.ustream.tv objectSubdoc

The .flv is Flash video, and why it is coming from UStream instead of YouTube? Maybe it's an alternate outlet for that feed?

Did not get a status 400 this time but got status 404 and two 304 www.google.com after the 404.

In your attached image of s.youtube.com. Here is what I got.

Status 404, under Headers tab, subheading Response headers: Content-Type: "text/html:charset=UTF-8" referer-policy: "no-referer" Content-Length: "1561" Date" "Mon, 01 May 2017 03:52:13 GMT"

Hope I got the information right that you need.

Thanks for all the help. Rob

A 404 "not found" response code is odd. Was it a "qoe" request as in my screenshot?

Could you check your REFERER-related preferences:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste referer and pause while the list is filtered

(3) If any of the items are bolded and set to a non-default value, you can make a note of them, then right-click > Reset to restore the default.

Note: I have network.http.referer.trimmingPolicy set to 1 and it seems to work.

I do not understand the question about "qoe"? I used the link; http://s.youtube.com/ and had to reload the page. Is this the screenshot you referred to?

Present settings: Search: referer

network.http.referer.XOriginPolicy default integer 0

network.http.referer.XOriginTrimmingPolicy default integer 0

network.http.referer.spoofSource default boolean false

network.http.referer.trimmingPolicy default integer 0

network.http.referer.userControlPolicy default integer 3

network.http.referer.sendRefererHeader default integer 2


I reset the following: network.http.referer.trimmingPolicy user set integer 1

Thanks, Rob

I was on a page you had linked to with little birds in a nest. I was viewing the Network Monitor and used qoe to filter down the list (highlighted/boxed area of the screenshot). Could you try it that way?

Hi Rob, if you reload the page and change the filter to youtube how much of what I see in the attached do you see? I assume at least some requests are sent to YouTube.

If I put youtube in the filter. I get nothing shown. Using the network tab and All tab.

Then I deleted youtube out of the filter and get the following results.

Okay, it seems you are getting to a critical point, but when I compare mine, it is not a plain text response, it's an encoded response that's over 7KB in size. Are you getting anything like that? If not, could you click the Response tab on the right side and see what it shows -- could be an error message?

That looks better than I expected from the summary line. It's still puzzling that the response header says

Content-Type "application/x-www-form-urlencoded"

but the summary line says plain; there's some kind of disconnect there.

In case there is a problem with an intermediary ("man in the middle") munging the brotli compression, do you want to try this test:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste enco and pause while the list is filtered

(3) Double-click the network.http.accept-encoding.secure preference to pop up an editing box, and remove this from the end:

<font face="courier new,courier"> , br</font>

so it looks like the line above it

<font face="courier new,courier">gzip, deflate</font>

Then click OK to save the change.

Any difference when you reload the eagles page?

Below is what I get for that line: After revision "gzip, deflate". I find it odd after "cache-control" it shows Expires:"Tue, 27 Apr 1971 19:44:06 EST"? Still failed to find video url but in the Status column of the Network Monitor it is all 200's with the first 1/3 gray dots and the balance green dots. Were making progress!
