A hard limit will kill the process as soon as either CPU or memory
consumption are above a defined limit for a certain amount of time.
A soft limit will throttle the CPU usage if above a defined limit and
kill the process if memory consumption is above a defined limit. The
soft limit can be enabled/disabled on demand.
The default is hard limit.
log_patterns allow to filter the FFmpeg log messages based on regular
expressions. Each entry of log_patterns is interpreted as regular
expression and matched against every non-progress log line emitted from
FFmpeg. All matching lines are returned in the matches array of the
report.
The scheduler allows to define when a process should run. It can be either
a timestamp in RFC3339 format or a crontab expression. If a scheduler is
given, reconnect and the reconnect delay will only apply to processes that
exited as failed.
The timeout allows to define when a process should be gracefully stopped.
It is measured from the actual start of that process including all reconnects
due to failures. If the process finished regularly, the timeout will be
reset.
The listing options are implemented by the query parameters size_min,
size_max, lastmod_start, and lastmod_end, or by the new ListOptions
type. size_min and size_max expect a number of bytes, lastmod_start
and lastmod_end expect a unix timestamp. All values are inclusive.
Because it doesn't make sense to replace the date placeholder at
process creation, it has to be replaced at every start of the process.
On process creation only the static placeholders (such as process ID)
are replaced. Dynamic placeholders (so far only "date") are not
replaced. On process start, a callback has been introduced that gives
the chance to change the command line. This is the point where
the restreamer replaces the date placeholders.
