Allows to manage the AV_LOG_PRINT_LEVEL flag as a prefix to the loglevel
option value, similar to the existing AV_LOG_SKIP_REPEATED flag.

Set the logging level used by the library.
Adding "repeat+" indicates that repeated log output should not be compressed
to the first line and the "Last message repeated n times" line will be
omitted. "repeat" can also be used alone.
-If "repeat" is used alone, and with no prior loglevel set, the default
-loglevel will be used. If multiple loglevel parameters are given, using
-'repeat' will not change the loglevel.
+Adding "level+" indicates that log output should add a @code{[level]} prefix to
+each message line. This can be used as an alternative to log coloring, e.g.
when
+dumping the log to file.
+If "repeat" and/or "level" is used alone, and with no prior loglevel set, the
+default loglevel will be used. If multiple loglevel parameters are given, using
+'repeat'/'level' will not change the loglevel.
@var{loglevel} is a string or a number containing one of the following values:
@table @samp
@item quiet, -8
