Hi. When applying the hevc_metadata bsf to a stream without VUI
information, the values in H265SPS.vui are not correctly inferred,
especially the fields inferred by bitstream_restriction_flag. When setting
VUI fields such as colour_primaries, cbs_h265_write_vui_parameters will
error out.
Source of the error could be in cbs_h265_read_sps, which only checks for
vui_parameters_present_flag and - if 0 - does not call
cbs_h265_read_vui_parameters (that would infer the parameters).
