Find faces in videos

[jakekapellen]

Describe the enhancement you'd like
I'd like to be able to find people inside videos. That way, I can see a full timeline/album of all content for a person.

Describe why this will benefit the LibrePhotos
This would be sweet! It would allow photos and videos together in those albums.

Additional context
This should be doable by sampling a frame every five seconds or so during the video, finding all the faces, and clustering the found faces as a separate subset, eliminating all noise points. From there, we could find the sample face closest to the centroid of each cluster and use that as the representative face to compare with the rest of the photo database. We would probably need to save these frames as separate metadata images, and labeling the representative face would instead indicate that the known face exists in the video (instead of a photo).

We could then update the albums page to accommodate this.
