Unlike image lazy loading, we don't support video lazy loading yet because:
- non-
youtubevideos use thevideotag which has noloadingproperty yet youtubevideos are embedded withiframeandiframehas noloadingproperty yet
Both of this cases could be worked around with JavaScript:
- non-
youtube: setsrcfrom JavaScript as shown for images: stackoverflow.com/questions/2321907/how-do-you-make-images-load-lazily-only-when-they-are-in-the-viewport/57389607#57389607.But this breaks page semantics however, we don't know how to work around that youtubevideos: same as above for theiframe, but this should be less problematic since YouTube videos are not viewable without JavaScript anyways, and who cares aboutiframesemantics?
