HTML5 SDK - AdError 400: There was an error playing the video ad on Chrome 48 for Android 6

[Arnaud Leyder]

Hi, 

I am seeing an impacting issue with playback of video ads through the HTML5 SDK on Android 6 devices.

It can be reproduced on your test page https://developers.google.com/interactive-media-ads/docs/sdks/html5/vastinspector?player=h5 with your sample tags https://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/single_ad_samples&ciu_szs=300x250&impl=s&gdfp_req=1&env=vp&output=vast&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ct%3Dskippablelinear&correlator=

Here is the log I have on my player and they are the same on the inspector:

adsManagerLoadedEvent

rmp.min.js:8 RMP: processAdsManager

rmp.min.js:8 U {type: "loaded", target: Y, b: Y, Gc: true, l: X…}

rmp.min.js:8 U {type: "contentPauseRequested", target: Y, b: Y, Gc: true, l: X…}

rmp.min.js:8 U {type: "start", target: Y, b: Y, Gc: true, l: X…}

rmp.min.js:8 Wd {type: "adError", target: Y, b: Y, Gc: true, h: Sd…}

rmp.min.js:8 RMP: getError - AdError 400: There was an error playing the video ad.

rmp.min.js:8 RMP: getErrorCode - 400

rmp.min.js:8 RMP: getInnerError - undefined

rmp.min.js:8 RMP: getMessage - There was an error playing the video ad.

rmp.min.js:8 RMP: getType - adPlayError

rmp.min.js:8 RMP: getVastErrorCode - 400

The issue here is that once the error has triggered the player stays on a black screen while the content playback in the background (you can also hear the ad sometimes). I have the same issue with ADV adTags. I could remember it was working fine 2-3 weeks ago so I guess maybe a Chrome or SDK update did bring something new to the table. 

I tried on an Android 5 device with Chrome 48 and I could not see the issue. Then I tried on an Android 4 device with Chrome 48 and the issue was there. I am not seeing any issue in iOS or Desktop.

Can you help me on this one?

Thanks

Arnaud

ok after further investigation I might think it has something to do with Chrome for Android as I cannot play a simple video tag on the devices where I can see the issue. I have filled a bug with Chromium.

Thanks
Arnaud

Hi Arnaud,

Have you been able to localize the source of the issue?  I'm having trouble reproducing it here on our end using Chrome 48 on Android 6.0.1 and Android 5.1.1.  The ad and content playback was seamless to me without any errors on the aforementioned platform.  

Let us know if you have further questions or issues,

Hi Vu,

Thanks for your answer.
I think the latest Chrome (or Android) update did something weird to some of my testing devices. I eventually restarted my Nexus 7 and the issue was gone.
