# We unconditionally enable codecs that do not require additional
# dependencies when building tvheadend. If support is missing from
# ffmpeg at runtime then tvheadend will simply disable these codecs.

# It is not necessary to specific all the --disable-*-static options as
# most of them only take effect when --enable-ffmpeg_static is given.
