Amazon Prime Video halting every 5-10 seconds

Reported by robinpri...@gmail.com, Nov 6

Issue description

UserAgent: Mozilla/5.0 (X11; CrOS x86_64 11021.56.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.76 Safari/537.36
Platform: 11021.56.0 (Official Build) stable-channel guado

Example URL:

Steps to reproduce the problem:
1. Open Amazon Prime Video in browser.
2. Select title to play.
3. Click play button. ;)

What is the expected behavior?
Video starts, streams smoothly.

What went wrong?
Video & audio stutters every 5-10 seconds.

Did this work before? Yes Pre- version 69? I did not take note of the date of last os update, did not expect this problem to persist so I have no exact date to report. About 1 month ago.

Is it a problem with Flash or HTML5? N/A

Does this work in other browsers? Yes

APV streaming fine for over a year, image quality suddenly degraded then crashed, reporting error 7031. Updated to Version 70.0.3538.77 (Official Build) (64-bit), cleared cache, cookies, history, log out/in, restart, disabled all extensions, etc. Streaming quality is good, but stutters every 5-10 seconds. Unwatchable. Reported to Amazon last week, spoke with rep on phone 2 days ago, they vaguely acknowledged that there is a problem between Prime Video and Chrome os and promised a fix within 2 weeks.

Thanks! Could you please also share chrome://media-internals logs?

Comment 3 Deleted

@robinpritchett : also, could you copy/paste in the Platform line from chrome://version? should be something like :
Platform : ######.##.# (Official Build) beta-channel <devicename>

I tried to repro on 2 different intel-based Chrome OS devices and playback was smooth. Thanks!
Platform: 11021.56.0 (Official Build) stable-channel guado
robinpritchett: Thanks for the quick response! 

I don't think you've captured media-internal logs for the repro case. Please try to repro the issue again, then go to chrome://media-internal and find the player for your repro case, and provide the logs associated with that player. Thanks!
Sorry, I'm obviously not a coder! I selected a different movie to reproduce the problem. There was a 30 second ad in front for their new show, naturally the ad played perfectly. The movie itself skipped as expected.
I think this is the log for that event.

Thanks for the log. I do see a lot of buffering state changes. We'll see whether we can repro here and get back to you.
I deleted #3 since it doesn't provide any useful info.

I filed an internal bug crbug.com/903558 for this.
Labels: M-71
Status: Fixed (was: Assigned)
Not fixed. Problem persists.

Logged out, restarted, updated, etc. Amazon Prime Video stutters approx. every 7 seconds except for on brand new "Prime Original" titles, ads, and trailers.

Thanks for your help.
Hi, It is fixed in Chrome 71. Can you check the Chrome version?
Version 70.0.3538.110 (Official Build) (64-bit), just updated yesterday.

When does 71 release?
ChromeOS is scheduled to be updated to version 71 next week. Or you can switch to beta channel to get Chrome 71 early.
