1181,dump_metadata should filter control-chars,vogelchr,,"My mobile phone embedds a form-feed/Ctrl-L in the metadata of the recorded videos, shown as ""**CTRL-L**"" below. It messes up my unix-terminal and hides information I really wanted to see.

Unfortunately, these control-chars are interpreted as ""clear screen"" in a normal unix-terminal, these chars (\1 ... \37) should be filtered on metadata dump.

Attached patch replaces these control chars with a question mark.
