The bug also appeared on Desktop version:
65.0.3311.3 for Linux
65.0.3315.3 for Linux

It worked fine (not buggy) on 65.0.3298.3.

I don't repro this bug on 65.0.3315.0 and 65.0.3318.0 for Win.

I recognize the versions given by extrom... : they were those I uploaded automatically with chrome dev update.

Quite strange that you could not reproduce because without doing anything it is broken. But :
- youtube is displayed well
- I didn't identify which types of videos or readers are impacted (google drive doesn't work - see new screenshot)
- More strange, even if the video isn't displayed, the picture "anouncing" video is shown

Haapily, I found a workaround to display videos. I disabled hardware video acceleration which was activated for a while (all switchs were by default before) !

Unable to reproduce the issue on reported chrome version 65.0.3315.3 using windows 10 with the below mentioned steps.
1. Launched chrome
2. Navigated to ttp://www.01net.com/astuces/comment-afficher-un-compteur-et-les-limitations-de-vitesse-dans-google-maps-sur-android-1332553.html
We are able to play the video without any issue. Attaching the screen cast for reference.

@Reporter: Could you please check the screen cast and let us know if we have missed any steps while reproducing the issue. As per your comment#6 the issue seems to be resolved, please confirm on this for further investigation.

Thanks!

I received an update of chrome : version is now Version 65.0.3322.3 (Build officiel) dev (64 bits).

Bug is still present when flags are all reset to defaults but I confirm that workaroud is to disable hardware acceleration to solve the problem (cf. screen cast).

I found another site where, even with my workaround, some videos aren't displayed while they are correctly shown with Edge (but not Firefox 57.0.4). I think it depends on the player :

http://www.allocine.fr/video/player_gen_cmedia=18372199&cfilm=55681.html 

this one is the trailer of an old movie. For recent movies, no problem with the workaround

Sorry ;-(

Are there new drivers available for your GPU? Generally this is a driver issue of sorts.

7chervet@ Thanks for the feedback.

Able to reproduce this issue on Windows 10, Mac OS 10.12.6 and Ubuntu 14.04 on the latest Canary 65.0.3323.0 and Stable 63.0.3239.132 using the URL given in comment #10.

Can observe that only the audio is playing, but the video is not seen.
Attached is the screen cast for reference.

This is a non-regression issue as it is observed from M50 Chrome builds. 
Hence, marking it as Untriaged for updates from dev team.

Thanks..

I made a test html file with local videos (See attachment).

All 5 videos played smoothly with 65.0.3298.3,
but not played with:
65.0.3311.3 (Only showed 5 still images)
65.0.3315.3 (Only showed 5 still images)

Not fixed in « Version 65.0.3325.18 (Build officiel) dev (64 bits) » that has been uploaded

since this issue can be fixed by disable H/W decoding, it's likely a GPU related bug.
7chervet@, can you report info in chrome://GPU?

hy,

You will find the results in the attached file hoping it helps !

sandersd@, this seems H/W related. can you take a look? chrome://gpu log is provided in c#18.
7chervet@, can you also provide a chrome://gpu log when enable H/w decoding?

I didn't see any answer to my Q in c#11, "Are there new drivers available for your GPU? Generally this is a driver issue of sorts."

Hy,

You will find attached the result of chrome://gpu with hardware acceleration. 

I use Driver Booster and all my drivers are up to date regarding GPU. Notice that I didn't encounter any problem until first Chrome update 65.0.3311.3

Hmm +gpu folks, since the only thing I see in the change log that might be video related is angle updates:

https://chromium.googlesource.com/chromium/src/+log/65.0.3311.0..65.0.3315.0?pretty=fuller&n=10000

Does chrome beta work for you? It should be on M65 now, so if it's not working this might be a dev-only experiment.

It is still not working with HW acceleration in Version 65.0.3325.31 (Build officiel) dev (64 bits)

Still not fixed in Version 65.0.3325.51 (Build officiel) dev (64 bits) I received today

The allocine site is serving mpeg4 videos, so it will never play in Chrome on desktop actually. If it has recently stopped working, it is a site bug of some sorts.

Is there another site that you are not seeing video on? I'm unable to reproduce the issue on the original link in comment#0.

With this URL and with the version given in comment 27, with HW acceleration on, I confirm that I hear the sound but the video isn't displayed. With no acceleration, it works fine.

But you can use url given in comment#14 : I just checked that videos are not displayed too whent HW acceleration is on

Can you grab chrome://media-internals when you try to play that video? I wonder if some sort of geo-fencing is going on.

(w/ hardware decode)

If you check chrome://gpu do you have any errors after trying to play a video? We're not able to reproduce this, so it must be something specific to your hardware.

Hi.
many info & more about this issue: https://bugs.chromium.org/p/chromium/issues/detail?id=820643&q=component%3AInternals%3EGPU%3EVendorSpecific&colspec=ID%20Pri%20M%20Stars%20ReleaseBlock%20Component%20Status%20Owner%20Summary%20OS%20Modified

Problem exist with ATI card.
Not solved.

Hi All
I have the same issue (video is not played but I can hear the sound)
I made some tests and found that the problem arises only in Windows 10 system (does not matter 32 or 64 bit), while Windows 7 is OK for both 32 & 64 bit
I tried Opera, Vivaldi and Chrome - they all have the same issue (while FireFox and IE 11 does not)
I have Toshiba Satellite A300 with ATI Mobility Radeon HD 3470 videocard with Microsoft drivers

Drivers are pretty old are there any newer ones?

>> Drivers are pretty old are there any newer ones?

No I do not think so. But again, under Win 7 old drivers work well

And when I run Opera with "--disable-direct-composition" and Hardware acceleration enabled - all seems to be fine
Does it mean, that in this case hardware acceleration works, but with some restrictions. And better using with "--disable-direct-composition" and hardware acceleration enabled, then simply remove hardware acceleration from settings?

Hmm, +zmo, probably this is a case which should be on the GPU blacklist if it's not working with direct composition. I thought there was another bug about that somewhere.

My understanding is without hardware overlay support, direct composition isn't doing anything in Chrome. So it's a bit strange to me why you experience the difference with/without the flag, because on AMD, we definitely don't have hardware overlay support.

sunnyps@: can you confirm the above or I misunderstood something?

Then why the same hardware, the same Chromium (Opera, Vivaldi, Chrome) does not break these videos on Windows 7??? And it seems that the drivers are the same at Windows 7 and Windows 10. So what is the difference here?

OK, let me correct it: we do create a different surface if DirectComposition is supported, even though we don't need it. So for now, let's just blacklist DirectComposition on AMD/NVidia GPUs where it's not needed. This should work around the bug here.

Next step here is to use direct composition only if overlays are supported.  This should be a straightforward change, but we don't absolutely need it for the time being.

Please use this bug to track the original issue that's seen on Windows only.  If you see video rendering bugs in Linux or Mac, they are most certainly other issues.

 Issue 820643  has been merged into this issue.

I wonder when the fix is going to be implemented? Any ETA (even approx)?

The CL in #46 should fix the issue. So if you download Chrome Canary, most likely it's already there.

Thanks. I'll be waiting for the stable release of Chromium and when Opera starts using it )

Per offline discussion with sunnyps@, we are going to limit this workaround to AMD GPUs only (probably driver 8.970.100.9001 only), so we could limit the scope of impact and merge back to Beta, so you will get this fix sooner.

Revert "Disable DirectComposition on everywhere except for Intel GPUs"

This reverts commit 95797d793ebf16c80259e84f1aea4aac69844b48.

Reason for revert: will limit the workaround to AMD gpus only, so we could merge back to Beta affecting less machines.

Disable DirectComposition on certain AMD GPUs/drivers.

Most user reports are for driver version 8.970.100.9001.

However, there is one report on AMD r7 M360 (0x6900) with driver 24.20.11016.4,
which is from May 2018.

Limit the scope of applying this workaround, so we can backport to Beta without
changing code path for most users, although in theory we don't need direct
composition on non Intel GPUs on Windows.

How do we know when this fix is going to be implemented in Release? And what number? 

This fix is implemented on top of tree and has been merged back to Chrome M70 branch.

So you will get this fix when Chrome is M70 or newer.

Use flexible surface compatibility extension for default pbuffer surface

EGL_ANGLE_flexible_surface_compatibility allows contexts to be able to
bind to surfaces with different formats e.g. with or without alpha.

With DirectComposition, we have a real surface inside a Begin/EndDraw
pair, and use a default 1x1 pbuffer surface outside of that.  That
surface must be created with flexible surface compatibility so that we
can MakeCurrent outside of Begin/EndDraw.

Noticed this while working on a related change.  There were some crashes
in MakeCurrent in SetSwapInterval which was fixed in a different way by
removing SetSwapInterval, but it's possible the root cause was this.
