      Description

      While trying to find a reason of "WinRT originate error - 0xC00D5212 : 'Decoder error'."

      in my app, and simulate it on standalone example, I found probably another issue, see below

       

      There're issues with playing several Hi-Res videos simultaneously with OpenGL RHI.

      Also it might be noticed that the frame rate for this videos is various for the same source. 

       

      See example . https://drive.google.com/file/d/1lJxNwJ-EXgx79H8FYVqP2VN8WUyz_MUg/view?usp=sharing.  

      Sorry, I had to upload it on my Google Drive because it's exceeded Jira's limit in 30 MB.

      The sample video itself is 42MB.

       

      Steps to reproduce:

      1. Build and run example
      2. Since started it plays the same video file in 4 Video controls simultaneously
      3. The issue can be observed right after start, or after clicking on "Reload videos" button several times.
