issue also see on HTML5 video from vimeo

From crash/ it looks like this is a browser crash, which indicates these two issues:
https://bugs.chromium.org/p/chromium/issues/detail?id=646643
https://bugs.chromium.org/p/chromium/issues/detail?id=621282

Duping into one of them.

Issue 646643 has OS=Windows, whereas this issue is for Chrome OS.  This issue has a specific cause of killing the GPU process manually via the task manager, which seems to be unrelated to issue 646643.  So the two issues should not be merged.

See issue 646960 for an explanation of why you should not merge issues just because they have the common crash signature "da39a3ee_5e6b4b0d_3255bfef_95601890_afd80709".

Pawel, this seems video-related, can you look?

Sorry, is this crash a second crash, happening after the initial crash triggered from the task manager?

issue reproduce on M-55 8872.16.0/55.0.2883.20.
Crash ID: 71ad9f2b00000000

Could you please clarify per my question in #7? Thank you.

The crash is first crash after kill GPU process from task manager

So basically GPU process crashes twice? Once as expected, and then when trying to reload the page and play the video again, it unexpectedly crashes again? Thanks.

I just want to confirm this issue is always reproduce so after first crash,I reload the page and play the video, do kill GPU process and the crash happen again.

Just want to clarify this test scenario,when manually kill the GPU process from task manager, it should not have any crash at all.

It seems killing a process manually shouldn't result into a crash. 

For the exact same steps on a website/tab without a video playing, does the same behavior not occur?

yes no crash occurs if without a video playing

posciak: ping on this p1 crash bug.

Although I agree we should look into this, I'm not sure this should be a P1 bug, given that this is triggered by the user manually killing the GPU process first...

I could reproduce the crash on cyan 8987.0.0.
- Play a youtube video.
- Press "End process" on GPU Process in Task Manager.

Observed result:
Chrome showed "Chrome didn't shut down correctly." I didn't see anything in chrome://crashes though.

I disabled video acceleration in chrome://flags (Hardware-acclerated video decode). I still could reproduce this. So this doesn't look like a hardware decode issue.

- I could not reprouduce the crash on elm 8987.0.0.
- I don't think this is a P1 either because users need to manually kill GPU process.

hsiangc@ Can you check if you can reproduce after disabling video acceleration in chrome://flags (Hardware-acclerated video decode)? Thanks.

wuchengli@ issue no reproduce on both M-55 and M-56 now 

Lowering priority as per discussion so far, please update if needed. @hsiangc, when you get a chance can you try a repro on stable? Want to see if the magical cure that affected 55 & 56 affected 54 as well. 

hsiangc@ Please try 54. If it doesn't repro in 54, we can close this.

issue still reproduce on M-54 8743.35.0/54.0.2840.101

M54 is already stable. It's too late to fix this in M54. I'm closing this.
