Camilo Celis Guzman 0cee3cd833 rtpvp8pay: rtpvp9pay: access picture_id property atomically
Atomically set and get the picture_id. This changeset only atomically gets
the picture-id when such property is queried on the element, on every other
place where it is accessed internally it is accessed directly.

This is because there is no MT scenario where we would be modifying this value
and reading it internally in parallel.
