Flash player for chrome

I failed to install flash player for chrome browser on jetson tk1. How can I do that?

So far, I am only able to access youtube through XBMC.

Thanks peba. I installed player as suggested in the link. Now I am able to play youtube videos. But video play back in 1080p resolution is very jerky. While a 1080p video stored on an sdcard plays well. Any solution?

If you play online video in 1080p your internet connection or video server might be the bottleneck.
Do you have a link to the Online video ? Which format is it ?
Have a look here:

You are correct peba. I tested using another internet connection and youtube 1080p video plays without any issue. Thanks
