The former approach to left the bin unfinished has some problems: the context cannot be shared because the vaapidecode is unlinked in many cases, leading to creating a VADisplay twice. Initially the bin is fully functional, constructed as (-----------------------------------) | vaapidecodebin | | (-------------) (-------) | |<--| vaapidecode |--->| queue |--->| | (-------------) (-------) | (-----------------------------------) When the context is shared and the VADisplay has VPP capabilities, before changing to READY state, the bin is reconfigured dynamically, adding the vaapipostproc element afeter the queue: (--------------------------------------------------------) | vaapidecodebin | | (-------------) (-------) (---------------) | |<--| vaapidecode |--->| queue |--->| vaapipostproc |--->| | (-------------) (-------) (---------------) | (--------------------------------------------------------) Signed-off-by: Víctor Manuel Jáquez Leal <victorx.jaquez@intel.com> https://bugzilla.gnome.org/show_bug.cgi?id=757957
