OK, understood

But that doesn't include the features already available in the SF version, right?

My main interest at this moment is to extract metadata that requires looking at the packets/frames currently (mainly for detecting interlaced content but other use cases will probably come with time). I guess it doesn't make sense to hack a probe for that into the current code as it is really a special case of what you already have in the SF version, except that it requires a -vframes option to do this efficiently.
