            Bug ID: 768692
           Summary: vaapidecode: make reverse playback smoothly
    Classification: Platform
           Product: GStreamer

     GNOME version: ---

Right now, reverse playback in vaapidecode is rough: only the key-frames are
shown. This is because the element runs out of VA surfaces (4 or so depending
on the codec).

The purpose of this report is to think how we can improve this situation, how
we can make reverse playback smoothly.
