[vlc-devel] [PATCH 2/2] core: don't reserve decoder pictures for filtering in direct renderering

It seems that vdpau has some filters that can handle
VLC_CODEC_VDPAU_VIDEO_XXX as input and output. There are actually 4 of
them so if you want to use all of them at once it won't work either.

This magic 3 number is odd. I understand it's better to allocate
things once to avoid failing later. But maybe the filter shouldn't
peek in a static reserved pool or we want to ensure a filter always
have something to process into, we should at least fix the number of
reserved pictures once we know how many filters will be used.
