Selenium chrome headless bowser and playing html5 video

[JT]

I am trying to set up Selenium chrome headless browser to run my scripts on docker containers.  When I run without headless mode, The scripts run fine. When I try headless, any scripts that play videos are not working.  Is there an issue with playing videos in headless chrome? And are there workarounds? My selenium scripts are written in C#.

Hey,

can you send me some screenshots of the errors that you get ?

I tried to set-up my BDD framework scripts run in headless jenkins server and was successful in doing that!

Send me the errors that you're getting so that i can help you!

Sorry, the screenshot doesn't help too much. The player window is supposed to close when video finishes playing however the video never plays so it fails when I look for the window disappearing.  

It seems to happen when I run chrome in headless mode without selenium too.

Do you have any tests that play html5 videos?

[Jayam, Vishnudeep]

No, i dont have any such tests playing  html5 videos! i will post the  screenshot of my base class! It might help u!

Thanks. I do not have any problem getting selenium chrome to run in headless mode. The problem is my tests cannot interact with playing a video.  The video wont play.

I'm assuming could be a visual/display problem in that embedded video playback/player plugin, etc. requires UI to properly function and headless mode puts it in a weird state. Video is different from static images and animated GIFs in the technology used to render the content.

Would be interesting to see if headless Firefox has the same issue or not. Alternatively, you could also try running the test in a headless setup that's not docker based. Could be docker related as well.

If you've narrowed it down to Chrome (docker or not), perhaps you could then bring this up with the Chrome/ChromeDriver team as it wouldn't be Selenium specific.
