Hi,
IMHO playbin2 should hide the difference between subtitles and subpictures.
>From the application point of view it's both subtitles, just that (as an
implementation detail) the subpicture subtitles are not plain text.

Having this differentiation in the public playbin2 API makes it more difficult
for applications to use it.

Also, from the inside of playbin2, both could be handled the same way. I was
planning to write a subtitlebin that abstracts this handling and for example
for something like assrender it would have to do exactly the same as for
something like dvdspu (the bin would have one video sink, one subtitle sink and
a video src)

(FYI this subtitlebin would also scale the subpicture subtitles to fit the
video and all that but that's not exactly interesting for this bug I guess)
