Description
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.

Can't reproduce it with master branch (commit: 40102a21374096ce0ba05c67c6e7474f176af2d0) on Linux (centos 7.3, MSS2017ESSR3). I see many qsv patches on master branch haven't been merged to ffmpeg 3.4.2. Could you try the master branch?
