           Summary: Videomixer sometimes doesn't push any EOS even though
                    all its collectpads are EOS.
    Classification: Platform
           Product: GStreamer

            Status: UNCONFIRMED

According to Sebastian on irc, videomixer was supposed to fill until the
segment stop when all collectpads were EOS.

The problem is there is no hint of such a code in videomixer, which makes me
wonder if somebody removed that or what. The code in fill_queues seems
needlessly complicated, and videomixer doesn't even realize all its collectpads
are EOS in certain cases.

I could fix it if I knew what we actually wanted. From my point of view, if we
decide that we want videomixer to "fill the void", we should at least have a
property to either disable that, or tell it to use the last computed frame
instead of the background. Our use case (editing) really doesn't work well with
black frames :)

I'll wait for opinions before further development.
