Fixed issue in CODEC regular expression

Previous regular expression for extracting codec information was wrong,
given a line that defines a variant it added information from “CODEC=“
text to the end of the line (including also information about
RESOLUTION or alternate rendition groups as part of the CODEC field).

This is not causing a functional problem (at least known by me)
although is making codecs field storing information that is not related
with the codec.
