 Summary of the bug:
 How to reproduce:
 {{{
 ffmpeg.exe -y -i src.mp4 -c:v libx264 -preset slow -b:v 8000k dst.mp4

 FFmpeg 4.1.3, Win64, built by Zeranoe.

 After re-encoding of my source video file with libx264 and bitrate 8000k
 mode I see many missing frames (about 300 frames).

 After re-encoding I see only 2 images and 3rd image is missing. I played
 created video in VLC player 3.0.6, MPC-HC, Media player in Windows 10.

 ffplay.exe plays correctly created video.

 If I use -crf 22 instead of bitrate mode created video looks correctly in
 all players.

 Source video (src.mp4) for testing:
