[FFmpeg-devel] [PATCH v3 1/5] avcodec/dovi_rpu - field and macro for metadata compression

[Cosmin Stejerean]

From: Cosmin Stejerean <cosmin at cosmin.at>


Add a field to enable or disable metadata compression since not all clients support this.

Introduce DOVI_ENCODING_OPTS macro to faciliate exposing this as an option to encoders.
