ffmpeg | branch: master | Chad Fraleigh <chadf at triularity.org> | Mon Oct 18 14:31:36 2021 -0700| [a90e41c59028ae4d83df81ebf05261aae15194b5] | committer: Andreas Rheinhardt

doc/examples/metadata: Constify values from av_dict_get()

Treat values returned from av_dict_get() as const, since they are
internal to AVDictionary.
