# encoding profile file #
#########################
#
# Note: by default, this file is installed to /etc/mpv/encoding-profiles.conf
# (or a different location, depending on --prefix). mpv will load it by
# default on program start. If ~/.mpv/encoding-profiles.conf exists, this file
# will be loaded instead.
#
# Then, list all profiles by
#   mpv --profile=help | grep enc-
#
# The following kinds of encoding profiles exist:
#   enc-a-*:  initialize an audio codec including good defaults
#   enc-v-*:  initialize a video codec including good defaults
#   enc-f-*:  initialize a file format including good defaults, including
#             selecting and initializing a good audio and video codec
#   enc-to-*: load known good settings for a target device; this typically
#             includes selecting an enc-f-* profile, then adjusting some
#             settings like frame rate, resolution and codec parameters
#
# AFTER including a profile of these, you can of course still change
# options, or even switch to another codec.
#
# You can view the exact options a profile sets by
#   mpv --show-profile=enc-to-hp-slate-7
#
# Examples:
#   mpv --profile=enc-to-dvdpal --o=outfile.mpg infile.mkv
#   mpv --profile=enc-f-avi --ofps=30 --o=outfile.avi infile.mkv
#   mpv --profile=enc-v-mpeg4 --ovcopts-add=qscale=7 --profile=enc-a-mp3 --oacopts-add=b=320k --o=outfile.avi infile.mkv
