Cannot run bob.bio.baselines of face images on video databases

After the introduction of baselines: https://www.idiap.ch/software/bob/docs/bob/docs/master/bob.bio.base/doc/baseline.html I noticed that I cannot run face baselines on video databases.

The preprocessor, extractor, and algorithm need to be wrapped inside bob.bio.video classes.

What do you think is the best approach to do this?
