# The official name of this plugin.
# This name will be used in the '-P...' option of VDR to load the plugin.
# By default the main source file also carries this name.


### Configuration (edit this for your needs)
#  comment out if not needed

# what kind of decoder do we make -
# if VAAPI is enabled the pluginname is softhdvaapi
# if CUVID is enabled the pluginname is softhdcuvid
# if DRM   is enabled the pluginname is softhddrm
VAAPI ?= 0
CUVID ?= 0

# if you enable DRM then the plugin will only run without X server
# only valid for VAAPI
DRM ?= 0

# use libplacebo -
# available for all decoders but for DRM you need LIBPLACEBO_GL
LIBPLACEBO ?= 1
LIBPLACEBO_GL ?= 0

# use YADIF deint - only available with cuvid
#YADIF = 1

# use gamma correction
#GAMMA ?= 0

CONFIG := -DDEBUG 		# remove '#' to enable debug output
