# Fake ffmpeg for the normalize-notify-sounds tests. Two modes:
# measure (args include the `volumedetect` filter): print a mean_volume line
# to stderr, driven by FAKE_MEAN (default -20.0).
# encode (otherwise): write to the output file (the last argument), driven
# by FAKE_FFMPEG_EMPTY (1 -> zero-byte output) and FAKE_FFMPEG_FAIL
# (1 -> exit non-zero without writing).
