# The config flags for the minimal ffmpeg build used in the program, reducing
# compile time and filesize by a decent amount.
# Surprisingly we don't need to compile and link any other external libaries to
# be able to decode most of the commonly-used file formats. We'll only start
# needing them if we want the user to be able to export mp4s or webms directly
# from the program.
# All bitstream filters and are enabled.
# All filters, devices, and HW acceleration are disabled.
# All protocols aside from 'file' are disabled.
# Encoders and muxers are TBD.
