 Here is very simple demonstration of the bug:


 >> ffmpeg -hide_banner -i 1.png -y 1.mp4


 Input image "1.png":
 [[Image(https://user-
 images.githubusercontent.com/29530279/38143163-8e07b0e8-343f-
 11e8-8545-96c51e8e21e7.png)]]

 Output video "1.mp4" (has only one frame):
 [[Image(https://user-
 images.githubusercontent.com/29530279/38143164-8e25a846-343f-11e8-971b-
 69b4d0958fbc.png)]]

 Do you see what I am talking about? Image is darker, colors were changed.
 I tried to set different pixel formats, to set different presets, to
 change quality, bitrate, etc, but no matter what I try, the output is the
 same.

 When will this bug be fixed? Thanks.
