[vlc-devel] [PATCH 18/19] filter_chain: do not drain pictures inside filter_chain_VideoFilter()

[Steve Lhomme]

Only do normal filtering. Proper draining after sending the source picture
to the filter chain should be done separately. A NULL picture is not allowed
anymore in filter_chain_VideoFilter().
