Comment (by arizel):

 Thank you for answer and suggestions. Actually I still have problem with
 colors. I have attached screenshot how it looks on my computer (MacOS).
 You can sure that problem still exists.
 I made frames using command:
 ffmpeg -i burger.mp4 -vf framestep=10 burger%3d.jpg
 Then I opened video by default application in macOS(quick time player) and
 default program for images. The main problem that iphone users see
 difference between their video and frame images and we need to fix that.
 Could you please try to reproduce this issue on macOS? I believe it will
 help to understand the problem.
 Thank you in advance!
