One thing that's always annoyed me about videos (especially tutorial videos) is that you can't search the content, either in your browser or on a search engine.
Now granted people have full transcripts of videos, but these do not work like reading a document where you can search for the text and then continue reading it where you found it, before and after. The equivalent in a video would have to be something like searching for the text and then having the text associated with a particular time point in a video. Close captioning does this to a point.
Are there any tools / APIs for proper ways of making the content of a video searchable using a search engine or the browser?
