 Summary of the bug:
 I get a video file filmed by android phone. Try to transcode using ffmpeg
 with qsv to accelate video decode. But it doesnot work well.
 How to reproduce:
 {{{
 ffmpeg.exe -v debug -hwaccel qsv -c:v h264_qsv -noautorotate -i
 VID_20180127_122111.mp4 -vcodec h264_qsv -f mp4 out.mp4
 ffmpeg version 3.4.2 Copyright (c) 2000-2018 the FFmpeg developers
 }}}

 But when I use CPU mode to decode, it works well:
 {{{
 ffmpeg.exe -v debug -hwaccel qsv -noautorotate -i VID_20180127_122111.mp4
 -vcodec h264_qsv -f mp4 out.mp4
 }}}

 ffmpeg.exe download from https://ffmpeg.zeranoe.com/builds/
 video file can play using android video player or vlc or other video
 player.
