Comment (by wenbin,chen):
According to
https://spec.oneapi.io/onevpl/latest/API_ref/VPL_func_vid_decode.html#_CPPv431MFXVideoDECODE_DecodeFrameAsync10mfxSessionP12mfxBitstreamP16mfxFrameSurface1PP16mfxFrameSurface1P12mfxSyncPoint
“Before decoding the first frame, a sequence header (sequence parameter
set in H.264 or sequence header in MPEG-2 and VC-1) must be present. The
function skips any bitstreams before it encounters the new sequence
header”
