Shira Player and Dome Player started to use GPU (Graphic Processor Unit).  This has increased the performance of video playback software by using the shader language. After this, in development of OpenGL sotwares GLSL(OpenGL shader language) will be used more. More about GLSL information-> 

Shira Player 1.5.0

This version has upgraded video performance sharing works between GPU and CPU. Now it can playback up to 4K encoded videos. Also jerky/choppy problem is solved by increasing playback performance on this version. This problem had been reported by several users.

Two checkboxes have been added on “Media Manager Window”. One of them is “High Performance” and the other is “Show FPS”.

Below image shows “Sample FPS Display” on projector screen. If playback speed is equal or greater than video frame rate the FPS display color will be “green” , if playback speed is 28 of 30 color will be “yellow“ for others values the color will be “red”.

 

High level video display cards will be needed to use high video performance. For example testing pc has NVIDIA GeForce GT 330M. You can reach its properties on the link. http://www.nvidia.co.uk/object/product_geforce_gt_330m_uk.html

Below images indicate if “High Video Performance” property status is checked or not. (Not checked status also represents before version of Shira Player 1.5.0)
