Add cropping metadata #346

Open mattrwoz opened 3 months ago

mattrwoz commented 3 months ago

This adds cropping metadata as proposed in CWG-D038. Accepted in the 10/10/2023 CWG meeting. Most of the text is the same as the proposal document with some minor adjustments:

Replaced "valid picture data" with "rendered"
Clarified the scope of the metadata to be from "metadata_crop OBU to Keyframe and/or next metadata_crop OBU" instead of just "until next metadata_crop OBU"

Some relevant discussion in the file format group on how such metadata can co-exist https://github.com/MPEGGroup/FileFormat/issues/77
