[FFmpeg-devel] [PATCH] Adding frame side data about green metadata

Greenmetadata is a set of metrics specified in ISO/IEC 23001-11.

They are used to predict the decoding complexity (in terms of cycles) of AVC frames. It is useful to perform DVFS (ie: CPU frequency scaling) in order to reduce decoder power consumption.

By the way, I'm not sure the patch was correctly attached. I'm trying one more time to attach it.
