Node.js Piping-how to write?

Question

I need to figure out how I can give exec permissions to write.

var exec = require('child_process').exec;
exec('ffmpeg -i file.ogv -f mp4 file.mp4', function(err, stdout, stderr){
});
// ffmpeg converts one video file to another.

How can I do this?

我使用node-fluent来解决这个问题，它可以更好地/授予权限。
