ffmpeg | branch: master | James Almer <jamrial at gmail.com> | Sat Jun 17 13:06:49 2023 -0300| [f7e0af5edc9e7c1315da35a98f017cb497f65ad4] | committer: James Almer

avcodec/evc_parser: stop exporting delay and gop_size

The former is a property a decoder may export, and the latter is only
used in encoding scenarios.
