We are facing a weird problem in Surface device with Windows RT operating system

When we are playing the video from Cloudfront CDN through JW player, Video takes long time to load and buffers very often than other devices. Sometimes it stops playing video. Same problem when we are using HTML5 video player

When we tried to play the video in Surface pro 2, it works fine.

What might me the problem here, it is because of CPU, GPU, RAM or any other browser issue in that specific device?

  • This seem to be more about a networking problem than a code problem? Could you share the code you have problems with? –  May 15 '14 at 06:44
  • @Epistemex: We tried with the page that contains only JW player and HTML5 player. Same problem exists. – Sathiyamoorthy May 15 '14 at 06:51

  • @Sathya : How was the performance of the same player with other tablet devices like iPad, Nexus, Samsung tablet, Can you give little more information on how was it behaving with other devices, other then surface? – Hitesh May 15 '14 at 13:17
  • Yeah, have you only tested on the surface? – emaxsaun May 15 '14 at 20:58

The GPU of the device is only used for decoding the video. If you can watch a video locally with no problems then you can almost certainly rule out the GPU as a bottleneck.

It doesn't seem very likely that the CPU is slowing you down but you should be able to check how much of the CPUs time the video player is taking through Task Manager or something similar.

The only 2 remaining factors I can think of that would affect you are RAM and your network hardware (since you've already tried watching it on another device on the same connection I'm assuming).

I'd get some info on what network speeds your device + connection is capable of and if you can rule that out, investigate how much RAM the browser is using.
