We have a playback problem in the vce module of the amd graphi=
cs card, when
using libva for h264 encoding, the field of pic_order_cnt_type in sps suppo=
rts
other options besides 0? Includes 1 or 2 and so on.
      Pic_order_cnt_type specifies the encoding method for poc (picture ord=
er
count), and poc identifies the playback order of the images. The poc can be
calculated from the frame-num through the mapping relationship, or it can be
explicitly transmitted by the encoder.
      When pic_order_cnt_type =3D 2, the POC calculation method relies on t=
he
least extra parameters (can save the number of bits in the slice header), a=
nd
it can only get the serial number of the top and bottom fields according to
frame_num. We need to play it quickly in this way.
