Comment (by teslan):

 Ok, So after another testing the decoder seems to be corrupted only after
 it is flushed (by one of these functions or both) and is then fed by a
 non-key frame. Now it makes sense that with a "proper" container this
 issue does not manifest itself.

 I worked around this by simply throwing away all non-key packets after a

 '''The issue is not fixed. ffplay still crashes with qsv_h264 after a seek
 in .ts and the behaviour is not consistent with h264, h264_cuvid or h264
 with any tested hwaccel (vaapi, vdpau, dxva2, d3d11va)'''
