[FFmpeg-devel] GreenMetadata complexity metric access through high level API

[Nicolas Derouineau]

Hello

>you should look at avframesidedata

Actually the issue is that the green metadatadata are concerning the upcoming frame (They are used to predict the upcoming complexity).

The avframesidedata are concerning a frame which is already decoded (so it's not useful in the case of greenmetadata).

We made a proof of concept using a home made parsing function (replacing av_read_frame() by a custom one), but we are thinking about a more portable solution.

you should look at avframesidedata
