Comment (by mmironov):

 I reproduced the problem. It appeared that AMD HEVC encoder has an
 additional parameter that controls frequency of IDR frames. And in turn
 IDRs are needed to indicate key frames used in seek. Please add
 "-gops_per_idr 1" to your command line. It will write IDR on every GOP.
 Maybe, it makes sense to change ffmpeg AMF default value from 60 to 1.
