[vlc-devel] [PATCH v4 06/24] filter_chain: use the picture_chain API

[Steve Lhomme]

chained_filter_t::pending represents the picture chain coming from incoming
pictures. It is set using vlc_picture_chain_get_and_reset() which removes a whole
picture chain from a picture, unlike vlc_picture_chain_PopFront which pops only
one picture.
