# The 2nd patch below disables IPC usage by explicitly defining the ANDROID
# macro.  It is needed for the media driver to work within the Chrome OS
# sandbox.  An upstream bug has been filed, requesting for a more meaningful
# name than ANDROID that can be switched on or off when calling cmake.
# The bug is https://github.com/intel/media-driver/issues/854.
#
# The 3rd patch below is a temporary workaround to address a video
# hardware decoding regression observed on Chrome OS on Gen12.
