Why using the exec in node.js:
child = exec("avconv -i " + result.params.fullDestinationFilename + " -ab 128k -vcodec libx264 -vb 2000k -r 24 -s 1280x720 " + convertedFileName720p + ".mp4", function (error, stdout, stderr) {
sys.print('stdout: ' + stdout);
sys.print('stderr: ' + stderr);
if (error !== null) {
console.log('exec error: ' + error);
}
console.log("CONVERTED!");
});
I get an error:
exec error: Error: Command failed: /bin/sh: avconv: command not found
In bash I can execute it normally. For node.js development I use nodeclipse.
For reference
var exec = require('child_process').exec;
exec("ls -la");

what's the difference in your own $PATH and the PATH of node? It would be safer to give the full path of avconv – glenn jackman
it is empty as I see in preferences. but the full path was the only quickest solution. thank you – static
