.SS "Output File Patterns:"
.IP
The \fB\-o\fR argument specifies the name of the file(s) to write to. If the
argument does not include any escape characters, the output will be
written to a single file. Otherwise, the filename will be calculated by
expanding the following escape characters:
.TP
%w
\- Frame width
.TP
%h
\- Frame height
.IP
%<n> \- Frame number, zero padded to <n> places (1..9)
.IP
Pattern arguments are only supported in conjunction with the \fB\-\-yv12\fR and
\fB\-\-i420\fR options. If the \fB\-o\fR option is not specified, the output will be
directed to stdout.
