• Error : ffmpeg exited with code 1 on AWS Lambda

  16 juin 2022, par Hassnain Alvi

  I am using fluent-ffmpeg nodejs package to run ffmpeg for audio conversion on AWS Lambda. I am using this FFmpeg layer for lambda.
Here is my code

  


    const bitrate64 = ffmpeg("file.mp3").audioBitrate('64k');
    bitrate64.outputOptions([
        '-preset slow',
    '-g 48',
    "-map", "0:0",
        '-hls_time 6',
        '-master_pl_name master.m3u8',
        '-hls_segment_filename 64k/fileSequence%d.ts'
    ])
    .output('./64k/prog_index.m3u8')
    .on('progress', function(progress) {
        console.log('Processing 64k bitrate: ' + progress.percent + '% done')
    })  
    .on('end', function(err, stdout, stderr) {
        console.log('Finished processing 64k bitrate!')
    })
    .run() 


  


  after running it via AWS lambda I get following error message

  


  ERROR   Uncaught Exception  &#xA;{&#xA;    "errorType": "Error",&#xA;    "errorMessage": "ffmpeg exited with code 1: Conversion failed!\n",&#xA;    "stack": [&#xA;        "Error: ffmpeg exited with code 1: Conversion failed!",&#xA;        "",&#xA;        "    at ChildProcess.<anonymous> (/var/task/node_modules/fluent-ffmpeg/lib/processor.js:182:22)",&#xA;        "    at ChildProcess.emit (events.js:198:13)",&#xA;        "    at ChildProcess.EventEmitter.emit (domain.js:448:20)",&#xA;        "    at Process.ChildProcess._handle.onexit (internal/child_process.js:248:12)"&#xA;    ]&#xA;}&#xA;</anonymous>

  


  I don't get any more info so I am not sure what's going on. Can anyone tell me what's wrong here and how can I enable more detailed logs ?

  


• Issues in executing FFmpeg command in Java code in Linux

  12 août 2017, par Tina J

  I have problems executing this ffmpeg command in my java code :

  ffmpeg -i sample.mp4 -i ad.mp4 -filter_complex "[0:v]trim=0:15,setpts=PTS-STARTPTS[v0]; [1:v]trim=0:5,setpts=PTS-STARTPTS[v1]; [0:v]trim=20:30,setpts=PTS-STARTPTS[v2]; [v0][v1][v2]concat=n=3:v=1:a=0[out]" -map "[out]" output.mp4

  I used the getRuntime() method below, but that doesn’t work for me. Even if I simply remove the ", still it doesn’t work. When I simply copy-paste the equivalent string in terminal, it works.

  String c1=" -i "+dir+"sample.mp4 "+"-i "+dir+"ad.mp4 -fi‌​lter_complex [0:v]‌​trim=0:15,setpts=PTS‌​-STARTPTS[v0]; [1:v]trim=0:5,setpts=PTS-STARTPTS[v1]; [0:v]trim=20:30,setpts=PTS-STARTPTS[v2]; [v0][v1][v2]concat=n=3:v=1:a=0[out] -map [out] "+dir+"output.‌​mp4";
  
  RunCommand("ffmpeg"+c1);

  Using this method :

  private static void RunCommand(String command) throws InterruptedException {
  
      try {
  
          // Execute command
  
          Process proc = Runtime.getRuntime().exec(command);
  
          System.out.println(proc.exitValue());
  
  
  
          // Get output stream to write from it
  
          // Read the output
  
  
  
          BufferedReader reader =  
  
                  new BufferedReader(new InputStreamReader(proc.getInputStream()));
  
          String line = "";
  
          while((line = reader.readLine()) != null) {
  
              System.out.print(line + "\n");
  
              //              System.out.println(ads.get(0));
  
          }
  
          proc.waitFor();  
  
  
  
      } catch (IOException e) {
  
      }
  
  }

  This one doesn’t work also, and printing the exit value shows this :

  Exception in thread "main" java.lang.IllegalThreadStateException: process hasn't exited
  
      at java.lang.UNIXProcess.exitValue(UNIXProcess.java:423)
  
      at parser.Parser.RunCommand(Parser.java:106)
  
      at parser.Parser.commandGenerator2(Parser.java:79)
  
      at parser.Parser.main(Parser.java:44)

  If I move the proc.waitFor(); before printing the exit value, it is 1.

  What is the problem ? Why it doesn’t run in Java code ?

• mips/mathops : remove 64-bit code

  mips/mathops : remove 64-bit code
  GCC is perfectly happy generating optimized multiplication code on its own for
  
  64-bit arches. GCC refuses to optimize the loongson code when in 32-bit mode,
  
  so I’ve left that.
