In the source code i have tried the two ways to start the gpu acceleration: first is in the libvlcInstance add the config options of "--avcodec-hw=d3d11va", the second is instance the libvlc.dll libvlc_media_add_option interface, neither they are visible. The second way even the vlcMedia can not load, In the vlcModule can not load and initialize. Anyone achieves the gpu acceleraton by this plugin. thanks.
