[vlc-devel] [PATCH v2 00/20] Add draining support to filters

[Steve Lhomme]

Changes since v1:
- fix misc compilation issues
- rework the fps code so that the extra pictures can actually be added
- rework the fps draining with more explanation. Using the p_sys->p_previous_pic->date
  was incorrect as it was shifted already.
- keep the reference date for VDPAU x2 deinterlacing draining
- add truncated commit text in last patch
