<blockquote><i><c>
my $frametotal,$fwide,$fhigh;
</c></i></blockquote>
<p>
You need to enclose the list of variables in parentheses or [doc://my] will only work on <c>$frametotal</c>.
</p>
<c>
my ( $frametotal, $fwide, $fhigh );
</c><br /><br />
<blockquote><i><c>
@vcmd=(@vcmd,"-vf","scale=min(1280\\,iw):-1");
</c></i></blockquote>
<p>
That is usually written as:
</p>
<c>
push @vcmd, "-vf", "scale=min(1280\\,iw):-1";
</c><br /><br />
<blockquote><i><c>
if($a eq "progress") {
my $pcent=$prog{"frame"}/$frametotal*100;
my $hcent=int($pcent/2);
my $bar="[".("#" x $hcent).(" " x (50-$hcent))." ] ";
$bar .=sprintf("%.2f",$pcent)."% fps=".$prog{"fps"};
print "\r$bar";
}
</c></i></blockquote>
<p>
I would probably write that as:
</p>
<c>
next if $x ne 'progress';
my $pcent = $prog{ frame } / $frametotal * 100;
printf '%s[%-50s ] %.2f%% fps=%s', "\r", '#' x int( $pcent / 2 ), $pcent, $prog{ fps };
</c>
