 When playing any h264 video in vlc(tested with version 2.1.4) using vdpau
 hwaccel, it aborts with the following assertion:

 Assertion desc->flags & (1 << 4) failed at libavcodec/utils.c:722

 Bisecting the issue ended up on the following two commits:


 Playing h264 without vdpau acceleration works fine in vlc.
 So does playing it with ffplay.
 Also using the ffmpeg cli util with hwaccel vdpau works fine.
