Disregard. 

Seems to have fixed itself after uninstalling and reinstalling and rebooting. 

I have noticed same issue today. Tried uninstalling chrome. Reboot. Now shows Android icon in place of chrome icon but launches chrome and plays videos on youtube. Installed newest chrome from play store and now all videos stop after 3 seconds again. Can play videos on Firefox though. I also have Nvidia shield.

When this occurs can you go to chrome://media-internals and grab the log shown for the player in question there?

+timav, do you have a shield tablet?

Dale: it looks like we don't have it.

Okay, Frank || Chris, can one of you order one of these tablets? Typically videos stopping after 3 seconds means that the video rendering underflowed and did not recover.

Yep, I'll order one now.

It just started happening again for me. Whatever I did to make it work was apparently only temporary. 

Here's my log:

Player properties 
render_id: 14
player_id: 0
pipeline_state: kStopped
event: WEBMEDIAPLAYER_DESTROYED

Timestamp	Property	Value

Maybe this might help. I found one youtube video that works. It is a "pen and teller fool us episode" from season 1. But another episode for season 2 does not work. Seems like they must be encoded differently?

One that works is https://m.youtube.com/watch?v=rnz92gYuHpI

One that doesn't is https://m.youtube.com/watch?v=K_-YtXdvcb4

I also seem to recall that advertisements would play fine, but when it got to the youtube video, it would stop after 3 seconds.

Another clue. If I request the desktop site for a youtube video that doesn't play, that video WILL play correctly.

Hmm, it's possible either the hardware decoder isn't working for vp9 which is why some of them are hanging, but h264 ones are working. What video_codec shows up in chrome://media-internals when it works versus does not?

Desktop site which works is vp9, vpxvideodecoder
Regular which doesn't is h264, gpuvideodecoder

It is a little different that what you expected. Looks to me that Hardware decoder isn't working for h264?  Beware I am by far from an expert on this subject, just trying to give accurate info. But I checked twice to make sure.

The root cause of this issue seems to be the feature "unified-media-pipeline" that is enabled by default in chrome 52.

Could you try disabling this feature from chrome://flags disable-unified-media-pipeline and verify if you still see the issue

Will take a look, we have a shield on order and are in communication with nvidia to try and get one sooner. As c#14 mentions, for now you can disable this feature using the chrome://flags setting.

I have uploaded https://codereview.chromium.org/2258113002 to suggest the source of the problem. Would appreciate if owners of the files in the change can take an initial look and post their comments there.

Having the same issue. I tried the disable-unified-media-pipeline and it seems to have fixed the problem.

@akshaya: That fix doesn't seem correct unless the Shield is doing something wrong to the buffers.

(I've replied on the code review, lets continue discussion there)

Nvidia is currently working on a fix for this. Marking external dependency.

@akshaya That setting fixed the issue for me. Videos now playing on latest version of Chrome on my Shield Tablet

Seems fixed on the shield devices I have, so closing.
