Bitstream width / height, may be different from width/height e.g. when
the decoded frame is cropped before being output or lowres is enabled.
@note Those field may not match the value of the last
AVFrame output by avcodec_receive_frame() due frame
reordering.
- encoding: unused
- decoding: May be set by the user before opening the decoder if known
e.g. from the container. During decoding, the decoder may
overwrite those values as required while parsing the data.
