[Affected versions]:
- latest Nightly 51.0a1 (2016-08-31)
- latest Aurora 50.0a2 (2016-08-31)
- 49.0b8 build1 (20160829102229)
- 48.0.2 build1 (20160823121617)

[Affected platforms]:
- Windows 10 x64
- Mac OS X 10.10.5
- Ubuntu 14.04 x86

[Steps to reproduce]:
1. Launch Firefox
2. Assure that e10s is on
3. Go to http://edition.cnn.com/videos and choose a random video from "Videos You Should Watch" section (or wait a few seconds, the first video is automatically started)
- inspect the chosen video 
- inspect the Browser Console

[Expected result]:
- The chosen video is properly loaded and no rendering issues are encountered

[Actual result]:
- The chosen video is not loaded 
- "Video Player failed error is :TypeError: this.getDOMPlayer(...) is undefined" error is thrown in Browser Console 

[Regression range]:
- I will investigate this as soon as possible

[Additional notes]:
- Switching e10s to off state, the videos are properly loaded and no rendering issues are encountered
- I could't reproduce the issue on other sites that also use Adobe Flash plugin (www.bbc.com/news; http://www.flashgames247.com/; http://www.miniclip.com/games/en/)
Component: Audio/Video → Audio/Video: Playback
Steps To Reproduce:
0. Always activate Flash Player and enable e10s.
1. Open http://edition.cnn.com/videos and wait for ~60seconds(depended on net speed)

Actual Results:
CNN Video would not autostart.
However, reload(F5) will start the video.

Expected Results:
CNN Video should playback automatically without reload(F5)

I never doubt Alice. The link between loading Flash and the load event of images is hard to imagine, perhaps there is some weird timing effect?
I'm having the same problems with cnn videos.  I run with the 64bit-PGO inbounds and started to have this problem a few days ago.  At the time I got this regression range which has a lot of patches between the bbad cset and the good one.  I don't see any of the patches in the regression range Alice came up with.

Currently I can get around the problem by turning off e10s.

@:streetwolf,
According to the affected version in comment #0, your range looks like not related to this bug.
So, Please file a separate bug.
@alice... My regression range seems to be in error.  I went back about 2 weeks and have the problem.  Isn't the patch that caused this from 6/15?  If so I would think I would have encountered this problem a long time ago.  I only noticed it less than a week ago.

I guess, in a recent, CNN has changed their code.
So CNN hits the old Firefox bug.

I double checked the bisection that Alice did, I got it down to the same day as Alice, but I don't have inbound builds cached so I couldn't go any further.
Andrei, this sounds to me like the videos still work and are playable. But autoplay does not work on first page load with e10s on. Can you confirm that is true ?  If it's just autoplay, and users can still click to play the videos, I am not going to block 49 on this issue.

It seems like this might be a site bug, moving to TE for diagnosis (but also looking forward to Andrei's response, because I'm not sure I can reproduce).

It is affected under only e10s mode. 
So, I think this is definitely Firefox e10s BUG even if this is caused by timing bug.
I'm testing in DevEdition 50 w/ e10s enabled (which is why I'm confused).
The problem is intermittent, you might have to try a few times to see it (restarting the browser in between).

When the problem happens the only way to fix it is to reload the page. There is no way to click play, and even choosing a different video to play on the page doesn't work.
I made it so that we send the load event for images even if we haven't parsed the size of the image yet (I think this goes against spec) and that does fix the site for me. I also made it so that only the url for the poster shown before the video (http://i2.cdn.turner.com/cnnnext/dam/assets/160906111804-bog-snorkelling-2-large-169.jpg when I did it) would wait until it had the image size before sending the load event and that also showed the broken behaviour.

So I think it is something to do with the load event of the poster image.

Correction: I was special casing it based on the url length, but another image the page loads could be the cause too, the small version of the same image http://i2.cdn.turner.com/cnnnext/dam/assets/160906111804-bog-snorkelling-2-small-169.jpg

I mention this because the delay introduced by doing the size decode async is much more significant for the "small" image because the "small" image load is trigger via js, but the "large" image is in the original html source of the page so it's size decode happens much earlier in the page load, when there are less tasks competing for resources. I saw 17-32ms for the "large" image, and ~500ms for the "small" image.

I investigated again this issue on 
- 49.0 build1 (20160905130425) 
- 49.0 build2 (20160907153016) 
- 49.0b10 (20160902105049)
- latest Aurora 50.0a2 (2016-09-07)
- latest Nightly 51.0a1 (2016-09-07)
using Windows 10 x64.
Only with e10s on, the autoplay is not working and also, any video chosen from the "Videos You Should Watch", "Recommended For You", "Don't Miss These Videos", "Best of CNN Digital Videos", "CNN Style and Travel" sections is not loaded; after a page refresh or after a browser restart, the problem is temporarily resolved - changing the video section returns the problem.
Flags: needinfo?(andrei.vaida)
I don't know if its totally related but often when loading a video I see 
Transferring data from: social-login.cnn.com and the page never completes.

A reload seems to either bypass that url or something as the page will then load almost instantly.

Pasting that url into the address bar results in a '301' error.
Jim do you know anyone good with e10s related timing issues who could help here?
Flags: needinfo?(jmathies)
Actually, I'm not marking this as blocking 49 since the same issue is on 48. So stopping people from updating from 48 won't help here. We do have some time to get a patch into another RC since we are slipping the release date.
tracking-firefox49: --- → +
Tech evang is probably the right call for this bug, if the network was slow it would be perfectly reasonable for the load event of the image to take 500 ms.
Daniel, maybe you are still at CNN and could take a look or pass this on.
Karl, can you help find a contact for this? I am also emailing CNN's tech support general email.

That's all I've got. I got lost in the page js trying to figure out who observed that load event of the poster image.
OK, thanks Timothy -- just wanted to confirm. I have a long flight to Berlin tomorrow and digging around this code is on my TODO list.
Can you please try this again with a more recent Nightly? I tried it today 2016-09-12 with Nightly and cnn.com via STR and it works fine for me.
Flags: needinfo?(iulia.cristescu)
Today's Nightly still hangs on social-login.cnn.com , video never loads.
I can still reproduce the problem on 2016-Sep-12 Nightly with e10s enabled.

As Alice already confirmed, the issue is still reproducible with latest Nightly 51.0a1 (2016-09-12), with mentioned STR.

Unfortunately this doesn't reproduce from Germany (in Dev Edition or Nightly, w/ TP disabled). Will test again from the US on Friday.
On my end the problem only happens if the video is located at .../vidoes.  Other flash videos at cnn like at money.cnn.com play fine.  Videos here are not in .../videos.

Not really, sounds like it's a dom events related issue of some sort. FWIW I can reproduce pretty easily in Nightly.
Flags: needinfo?(jmathies)
Trying to understand the status here. We are still in needsdiagnosis.

0. Using Firefox Nightly 52.0a1 (2016-09-22) (64-bit) with e10s on OSX 10.11.6 (15G1004) without Flash installed at all. No tracking protection on. Clean Profile.
1. Going to http://edition.cnn.com/videos
2. Video on the home page starts automatically without issues.
3. Click the second video in the caroussel, video starts and plays without issues.
4. Randomly clicking on a video down the page such as
   http://edition.cnn.com/videos/travel/2016/05/11/biggest-airplane-antonov-an-225-mriya-orig-nws.cnn?iid=ob_video_vr2
   It takes a bit of time, then the ads plays, then the video (just to be patient).

The player used is 
https://www.theoplayer.com/

```

transitions are definitely not smoothed, with a **lot** of trackers and HTTP requests. I see some requests to HLS files too. Some videos are stalling sometimes without specific reasons, except waiting on trackers to react.

Like for example now the carousel is sending videos in chunks


For example a click on thumbnail starts the initialization process:

BUT THEN the video is stucked. After retrying it, it worked. So sometimes it gets stopped.

The pause/play combination is also a recipe for getting the video stalled.

Comment #11 suggests the issue as reported is about video autoplay on page load (which doesn't reproduce for me here in Portugal, in any browser w/ new profiles, FWIW).
So, Dennis (Germany), Adam (Canada) and I (USA) just tried to reproduce and none of us can. Adam also VPN'd to Romania. Ways we've tested this:

w/ Flash always enabled
w/ Flash ask to activate
w/o Flash even installed on system
In a private tab w/ tracking protection off

STR: 

0) make sure e10s is enabled
1) go to http://edition.cnn.com/videos
2) wait for video to autoplay

For Dennis and myself, we get a localized ad, then an autplay video about Chinese telescopes. Adam just gets the video without an ad.

Iulia, does this still repro for you? Not sure it's worth tracking at this point.
Flags: needinfo?(iulia.cristescu)
Still does not play here, in the US, with latest Nightly build win32, e10s enabled, and tracking protection enabled.

Using on win10 x64

New Profile does not make any difference, video never starts and hangs waiting for 'social-login.cnn.com'
> Still does not play here, in the US, with latest Nightly build win32, e10s enabled, and tracking protection enabled.

So, tracking protection is not a default configuration we ship with (currently, anyways). liz, I don't think we should track due to TP bustage. WDYT?
Flags: needinfo?(lhenry)
(Also, as reported, it doesn't seem like TP is related. But as reported, I can't get it to reproduce anymore.)
I wasn't using tracking protection when I was able to reproduce.

I tried to reproduce on current nightly, and nightly from back when I could reproduce, but I couldn't reproduce now. I'm guessing cnn changed their site.

I investigated this issue on Windows 10 x64, Ubuntu 14.04 x86 and Mac OS X 10.11, using latest Nightly 52.0a1 (2016-09-26), latest Aurora 51.0a2 (2016-09-26), 50.0b2 (20160926162149) and 49.0.1 build3 (20160922113459), with a clean profile, Shockwave Flash installed and set on `Always Activate` and  with e10s on. I encountered the same issues as I mentioned in comment 19 and comment 0, but with some differences: 
- after opening the site, the autoplay is not working and also randomly chosen videos are not playing - these are intermittent (if they are not observed from the 1st try, they occur after spending some time on the site and switching videos)
- after reload / restart, the problem is resolved, but just temporarily - untill a video from another section is chosen
- changing again the section may resolve the situation, but still temporarily
Flags: needinfo?(iulia.cristescu)
Thanks tnikkel and Iulia for checking again. Sort of at a loss on how to proceed with debugging given that it doesn't reproduce for anyone on my team. It also makes it hard to approach CNN without concrete steps to reproduce.
ok finally this morning I have something which is not working. On this video:
http://edition.cnn.com/videos/politics/2016/09/27/donald-trump-microphone-first-presidential-debate-sot.cnn/video/playlists/2016-debates-the-morning-after

It doesn't auto-start
And when I click the play button it doesn't start either.

I'm running the latest inbound and I no longer have the problem as stated in this report.  Some other patch must have 'fixed' the issue.
Perhaps things are working now due to a change by CNN?
> Perhaps things are working now due to a change by CNN?

Possibly. Or possibly there are a few bad ads that screw this up. That would explain why it appears intermittently and in some locales and not others.
I disabled my adblocker which is uBlocko. the latest beta version. and the problem came back.  Enabled uBlocko again and the video played.  With prior versions of uBlocko videos wouldn't play.  So it might be the new beta version I'm on or perhaps even a new ad filter or two that 'fixed' things for me.
The beta version of uBlocko has a couple of fixes that affect Firefox.  Perhaps these are helping to fix the problem.  Here's a link to them:  https://github.com/gorhill/uBlock/releases/tag/1.9.11rc1
Seems I have two problems.  Videos like the one at http://www.cnn.com/videos/weather/2016/09/27/nccorig-weather-typhoon-megi-landfall.cnn which weren't playing before now are.  However, videos at http://edition.cnn.com/videos still hang unless I refresh the page.
I was wrong about videos not playing at http://edition.cnn.com/videos.  They do play after about 5 seconds or so.

So are these videos working for you? I was able to reproduce a week ago, but can't in current nightly (52.0a1 (2016-09-28) (32-bit).

In safe mode the example video at http://www.cnn.com/videos/weather/2016/09/27/nccorig-weather-typhoon-megi-landfall.cnn would not play right away unless I did an F5 refresh. Videos at http://edition.cnn.com/videos did play but a crash dump was produced in the background. Back in normal mode the videos at http://edition.cnn.com/videos also played and I didn't get a crash dump. The other video also plays fine.

I'm leaning towards some type of ad or some other thing that uBlocko is blocking as being responsible for all videos working as they should at CNN. Of course this is really just a serendipitous workaround. Obviously one shouldn't need an ad blocker to get the videos to work correctly I would think.

I have a discussion over at http://forums.mozillazine.org/viewtopic.php?f=23&t=3024111 you might want to peruse.
Btw... I'm on 64-bit Fx52.
Still 100% reproducible here:

Clean un-altered Profile

Visit cnn.com main page
Select any video from front page, loading occurs indefinitely.

Open browser Console and note tons of errors...

Running Win10 Anniversary Update x64 OS
Just to reiterate, without uBlocko enabled I get the same errors.  With uBlocko enabled the videos play fine.  Something that uBlocko is doing appears to be 'fixing' the problem for me.
Sounds very much like this is some specific ad. That would also explain why the videos play when the page is reloaded. If we have a specific example of an ad that makes the page fail, that might help CNN to figure out what the bad ads are, or it may be something we can defend against in Firefox, but I agree with Mike that we don't need to track this for 49.
