I keep getting EPIPE error, on stdin stream and I can't find a reason:
This is my code:
var checkFile = function(data, callback){
var child_process = spawn('ffprobe', ['-print_format', 'json', '-show_format', 'pipe:0']);
var stdInError = function(e) {
console.log(e);
}
child_process.stdin.on('error', stdInError);
var generalError = function() {
console.log("general Error" + "\n");
}
child_process.on('error', generalError);
child_process.stdout.on('data', function(data){
console.log("data" + "\n");
console.log(data);
console.log("\n");
});
child_process.on('close', function(){
console.log("close" + "\n");
}
var exit = function(){
console.log("exit");
}
child_process.on('exit', exit);
console.log("write" + "\n");
child_process.stdin.write(data);
child_process.stdin.end();
};
And this is my output:
write
data
<Buffer 7b 0a 20 20 20 20 22 66 6f 72 6d 61 74 22 3a 20 7b 0a 20 20 20 20 20 20 20 20 22 66 69 6c 65 6e 61 6d 65 22 3a 20 22 70 69 70 65 3a 30 22 2c 0a 20 20 20 ...>
data
<Buffer 0a 7d 0a>
{ [Error: write EPIPE] code: 'EPIPE', errno: 'EPIPE', syscall: 'write' }
exit
close
I cannot find a reason for this error, i have also tried to implement
child_process.stderr.on('data', function (data) {
//throw errors
console.log('stderr: ' + data);
});
And every line printed from ffprobe (which is a software to check audio/video files specs) is marked as stderr. For example:

After few tests I found a bug and the error is caused by a too big file.
