# Handbrake normally uses its own copies of the libraries it uses, for better
# control over library patches.
#
# This derivation patches HB so it doesn't do that. The relevant patches
# are added to the Nix packages and proposed upstream instead. In several cases
# upstream already incorporated these patches.
# This has the benefits of providing improvements to other packages,
# making licenses more clear and reducing compile time/install size.
#
# For compliance, the unfree codec faac is optionally spliced out.
#
# Only tested on Linux
#
# TODO: package and use libappindicator
