Comment:

 The cbs_h265 code completely ignores the possibility of
 reserved_payload_extension_data that may be present at the end of every
 SEI message. The uploaded sample has 8 zero bits of
 reserved_payload_extension_data present.

 (The current version of the spec says that reserved_payload_extension_data
 shall not be present in bitstreams conforming to this version of the
 specification, so its presence may very well be a bug somewhere. But even
 then cbs_h265 should not error out and has to treat this as potential
 reserved_payload_extension_data; right now this seriously impairs
 cbs_h265's forward compatibility.)
