Request for opencv style .grab() and .retrieve() feature

Open dmenig opened this issue 4 years ago • 0 comments

The opencv VideoCapture class has grab and retrieve methods that allow it to ingest codec data but not actually decode a frame, which saves compute power (not 100% though ofc).

It would be great to have this on VideoLoader in order to save GPU ressources.

Cf https://docs.opencv.org/3.4/d8/dfe/classcv_1_1VideoCapture.html
