Re^2: Passing an in memory scalar to an external command as an argument

I would suggest:

use IO::Pipe;
my $pipe = IO::Pipe->new();
$pipe->writer(qw(ffmpeg -i pipe:0));
print $pipe $mp3;

to avoid the shell being used to launch ffmpeg.

I like that solution. But I need to capture stdout also (so I am actually using open2 for this). Can I write and read using IO::Pipe? The docs look like it is one or the other.	[reply]

It is possible, but open2 is easier: `$pid = open2(\CHLD_OUT, \CHLD_IN, 'ffmpeg', '-i', 'pipe:0');` [download]	[reply] [d/l]
