Detailed Description

Cache maintenance

Creates a POSIX timer that starts the cache maintenance in preset intervals. To ensure that only one instance of FFmpegfs cleans up the cache a shared memory area and a named semaphore is also created.

The first FFmpegfs process acts as master, all subsequently started instances will be clients. If the master process goes away one of the clients will automatically take over as master.
