Comment (by Balling):

 Yep, that is the same issue:

 Lav\ffmpeg.exe -hwaccel d3d11va -i "example.h264" -f md5 -

 gives cb41681f69478a81624b15f11ff96673

 and so does ffmpeg master, for

 Lav\ffmpeg.exe -hwaccel d3d11va -i "example.h264" -f md5 -


 this gives cb41681f69478a81624b15f11ff96673, **yet for master ffmpeg it
 gives  7ff0f074231730af056ed9dc526906b3.
 **

 This is indeed my bug.
