Comment:

 The problem is more complex as ffmpeg incorrectly decode also yuv format.
 Reference picture was taken after the following commands:
 1 - ldecode.exe -i eva.h264 -o eva_ldecod.yuv (h.264 stream was extracted
 from mkv with mkvextract tracks command)
 2 - Using yuv player (https://github.com/Tee0125/yuvplayer) I saved 288th
 frame.
 3 - ffmpeg -s 1920x1080 -i eva_ldecod.yuv -ss 11.46 -frames:v 1
