/* Runs a pipeline and clasifies the media pipelines based on the
* authenticated user.
*
* This test requires 2 cpu cgroups to exist named 'user' and 'admin'.
* The rtsp server should have permission to add its threads to the
* cgroups.
*
* sudo cgcreate -t uid:gid -g cpu:/user
* sudo cgcreate -t uid:gid -g cpu:/admin
*
* With -t you can give the user and group access to the task file to
* write the thread ids. The user running the server can be used.
*
* Then you would want to change the cpu shares assigned to each group:
*
* sudo cgset -r cpu.shares=100 user
* sudo cgset -r cpu.shares=1024 admin
*
* Then start clients for 'user' until the stream is degraded because of
* lack of CPU. Then start a client for 'admin' and check that the stream
* is not degraded.
