AWS Lambda : ffmpeg thumbnails Generator : empty JPG
3 septembre 2020, par MagikeyWhen a video is uploaded on S3 i want to store a JPG screenshot.



On a lambda function with amazon AWS, i do :



...

 let tmpFile = createWriteStream(`/tmp/screenshot.jpg`)

 var ffmpeg = spawn(ffmpegPath, [
 "-ss","00:00:05",
 "-i", target,
 "-vf", "thumbnail,scale=200:200", 
 "-qscale:v" ,"2",
 "-frames:v", "1",
 "-f", "image2",
 "-c:v", "mjpeg",
 "pipe:1"
 ]);

 ffmpeg.stdout.pipe(tmpFile).on("error", err => {
 console.log("Error A: ",err);
 });

 ffmpeg.on('error', err => {
 console.log("Error B", err)
 reject()
 })

 ffmpeg.on('close', code => {
 tmpFile.end();
 console.log('Log A', ffmpeg);

 child_process.exec("echo `ls -l -R /tmp`",
 (error, stdout, stderr) => {
 console.log(stdout)
 });

 resolve()
 })
...




But the result is an empty JPG file in S3.



Logs shows no errors, my "target" is OK, stdout ls show me the empty JPG file.



I have try a lot of things, like use other version of ffmpeg but same.



There is the "console.log('Log A', ffmpeg)" :

issue streaming to instagram with FFmpeg
24 septembre 2021, par 1 K1Trying to stream from OBS using nginx server to Instagram using ffmpeg. There are no problem If I stream with a same settings to facebook. There is only a problem while streaming to Instagram. Also, if I do stream a video file instead of camera from OBS, there are no problem. So there is a problem While streaming from OBS through nginx server with ffmpeg.


command is :
ffmpeg -i rtmp://192.168.12.190:1935/live -filter_complex " [0] transpose=dir=1 [rotated] ; [rotated] scale=480:-2 " -max_muxing_queue_size 9999 -preset superfast -b:v 2000k -minrate 1500k -maxrate 3000k -bufsize 3200k -vcodec libx264 -r 30 -f flv rtmps://live-upload.instagram.com:443/rtmp/!streamKey!

ProcessBuilder is not called when trying to start a process
15 juin 2022, par xnokI am trying to understand more about the ffmpeg usage in JavaCV for android studio and for said task I am trying to use ProcessBuilder. I tried writting a simple program to debug the
pb.start();
Although, I am not getting a response. What I did was to start a default/empty activity and pasted the following program :

package com.example.myapplication;

import androidx.annotation.RequiresApi;
import androidx.appcompat.app.AppCompatActivity;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;

import org.bytedeco.javacpp.Loader;

import android.os.Build;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends AppCompatActivity {
 static final int cols = 192;
 static final int rows = 108;
 static final String ffmpeg = Loader.load(org.bytedeco.ffmpeg.ffmpeg.class);
 static final String rtmp_url = "test.flv";
 static final String[] command = {ffmpeg,
 "-y",
 "-f", "rawvideo",
 "-vcodec", "rawvideo",
 "-pix_fmt", "bgr24",
 "-s", (Integer.toString(cols) + "x" + Integer.toString(rows)),
 "-r", "10",
 "-i", "pipe:",
 "-c:v", "libx264",
 "-pix_fmt", "yuv420p",
 "-preset", "ultrafast",
 "-f", "flv",
 rtmp_url};
 @RequiresApi(api = Build.VERSION_CODES.O)
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 new Thread(t1).start();

 }
 private static Runnable t1 = () -> {
 Log.e("TAG", "void OnCreate called successfully!");
 ProcessBuilder pb = new ProcessBuilder(command).redirectErrorStream(true);
 pb.redirectErrorStream(true);
 try {
 Process process = pb.start();
 BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
 OutputStream writer = process.getOutputStream();
 Log.e("TAG", "Something good happened here");
 } catch (IOException e) {
 e.printStackTrace();
 Log.e("TAG", "Nothing good happened here");
 }
 };


}



My current problem is that I can't seem to start properly the processBuilder process via pb.start() ;


I get the following logs from the logcat panel :


2022-06-14 17:24:46.328 13371-13371/com.example.myapplication E/TAG: void OnCreate called successfully!
2022-06-14 17:24:46.333 13371-13371/com.example.myapplication E/TAG: Nothing good happened here



I'd like to understand why is it skipping the try/catch block and not starting the process ?


EDIT : I made some changes as per @g00se's suggestions and I got the following stack trace from the code above :
