# The goal of the mediaserver split is to place media processing code into
|
|
# restrictive sandboxes with limited responsibilities and thus limited
|
|
# permissions. Example: Audioserver is only responsible for controlling audio
|
|
# hardware and processing audio content. Cameraserver does the same for camera
|
|
# hardware/content. Etc.
|
|
#
|
|
# Media processing code is inherently risky and thus should have limited
|
|
# permissions and be isolated from the rest of the system and network.
