Youtube video playback starts but stops immediately.

I tried running both IE10 and 11, Firefox and Chrome and they all have the same unwanted behaviour. When a Youtube video is used as a source the playback starts and the video is seekable but stops playing immediately.

My player (v6.5.3609) is configured correctly and works perfectly for all operating system and browser combination, except for windows 8.1. The version of Flash that I'm running is up to date (v13.0.0.214) and identical on both my mac and other windows boxes. I am not using an add-blocker.

The following error is shown in the console:
Error: Ad adLoadError error: Unable to request ads from server. Cause: Error #2048: Security sandbox violation: http://s.ytimg.com/yts/swfbin/player-vfltTelqG/ad3_f9.swf cannot load data from http://googleads.g.doubleclick.net/. errorCode: 1103

The Flash debugger log also shows a bunch of **Security sandbox violation** errors resembling the one above all related to request going to Google/Youtube servers.

I found this quirk when using JW Player in my own application but the same behaviour can be replicated using the wizard on jwplayer.com.

Not sure it will make any difference, but your first step should be to update to JW Player 6.8.

Then, can you give us a link to your page?

I thought you could find your way to your own wizard but here's a link: <a href="http://www.jwplayer.com/wizard/">http://www.jwplayer.com/wizard/</a>

The only platform I know for sure this happens is <strong>Windows 8.1</strong>

As I mentioned, the same behaviour applies to the implementation in my own application (not public, so I can't link) and the JW Player wizard. Version does not seem to matter.

Hi,

I’m currently not seeing an issue with our wizard + youtube video. Again, if you can send over a public-facing page with steps to reproduce the issue, we can take a look.

The only publicly available example I can come up with without giving you access to my personal Windows 8.1 VM is BrowserStack.

Here's a link with an instance that has the unwanted behaviour:

http://www.browserstack.com/start#os=Windows&os_version=8.1&browser=IE&browser_version=11.0+Desktop&url=http%3A%2F%2Fwww.jwplayer.com%2Fwizard%2F&resolution=1280x1024&speed=1

You can create a free dummy account to try it out.

Interestingly enough, I have seen this sort of behavior, however I’ve only seen it while testing in VMs. (On Windows 7 VMs as well) I’ll definitely take a look further, however the issue doesn’t happen on every VM, and I have not seen this on actual Windows machines.

I just tested on my machine at home that runs Windows 8.1 which has the same version of flash and can confirm the issue is not isolated to virtual machines.

If can provide the flash debugger logs if it helps you out or any other logs that might be useful. I'm not sure if I should post them here thought, the layout will probably break like it did in my previous post.

I'm afraid this question will get buried without any follow up.

How do I get updates about the issue, is there a tracker I can subscribe to?

We’ve been taking a look via our VMs, but we can’t seem to replicate this with a youtube clip, oddly enough. Out of curiosity, is this happening on IE11 metro (Er… “Windows Store App”) or within the Windows desktop mode? We have tried both, but narrowing this down should help a bit more.

I only tested in desktop mode on both my native windows box and the Browserstack VM I linked earlier. I'll have a look at metro mode this evening.

If you're getting different results on your own VMs you can compare them to this Browserstack VM that has the issue (just tested to make sure there are no updates): http://www.browserstack.com/start#os=Windows&os_version=8.1&browser=IE&browser_version=11.0+Desktop&url=http%3A%2F%2Fwww.jwplayer.com%2Fwizard%2F&resolution=1280x1024&speed=1

Video used if that even matters (has preroll adds): http://www.youtube.com/watch?v=HkMNOlYcpHg

p.s.: Is there a clean way to post hyperlinks here?

Hmm.. still working for me on Windows 7 and my coworker on Windows 8.1. Let me know if metro mode makes any difference.

Metro mode suffers from the same issue as well as Firefox (30.0) and Chromium(33.0). I'm guessing this might be a Adobe Flash problem?

Flash versions tested:
- 13.0.0.214
- 14.0.0.125

I assumed remoting into my windows 8.1 box at home had nothing to do with this issue because playing video's on Youtube works perfectly.

I tried again, physically sitting behind the machine instead of using remote desktop and the problem did not occur.

As you mentioned using a VM can cause unexpected behaviour like this but using remote desktop on a host operating system does too...

The weird thing is that remoting into a Windows 7 or 8 box works just fine. Any idea what might be causing this? I'm guessing some weird streaming optimisation but why does it work when watching directly from Youtube then?

For completion: I'm using Microsoft Remote Desktop (8.0.7) on OS X (10.9.3). The program does not mention a protocol but I'm pretty sure it's RDP.

For RDP (And possibly VMs in this case) I do know that different video card drivers get utilized. I’m curious if this could be causing some problems that we’re seeing. If you try tinkering around with your hardware acceleration settings within Flash, is this having any influence?
