• Class "FFMpeg\FFMpeg" not found

  16 août 2024, par Saeed Eisakhani

  I installed ffmpeg on xampp by COMPOSER. I installed FFMPEG on windows before.


  


  Then with the command composer require php-ffmpeg/php-ffmpeg installed php-ffmpeg


  


  I use code below (from php-ffmpeg github) for a test but this does not work

  


  <?php

require '../../phpMyAdmin/vendor/autoload.php';

$ffmpeg = FFMpeg\FFMpeg::create(); // line 5 that error referees to 
$video = $ffmpeg->open('video.mpg');
$video
    ->filters()
    ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
    ->synchronize();
$video
    ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
    ->save('frame.jpg');
$video
    ->save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4')
    ->save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
    ->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');

?>


  


  This is the error I encounter.


  


  I read many and many similar questions but almost all of them suggest require '../../phpMyAdmin/vendor/autoload.php'; that I have it in my code.

  


• FFPMEG command to record screen works only from cmd on windows but not from my Java class

  21 mars 2024, par Youssef Hammouma

  i have a JUNIT test that uses a Java class called ScreenRecordingWatcher where i specified my ffpmeg command to record the computer when my test fails.

  


  But unfortunately, my command only works from my cmd and not from my class, On both sides it generates successfully my file, but when it is generated from my Java class, the file is not readable from my windows player (0xc10100be error).

  


  Here is the command i am using :

  


  C:\outils\ffmpeg-master-latest-win64-gpl\bin\ffmpeg.exe -f gdigrab -framerate 30 -i desktop -c:v h264_nvenc -qp 0 C:\outils\video\output.mkv


  


  Here is the same command from my class :

  


  public class ScreenRecordingWatcher extends TestWatcher {

private static final String FFMPEG_PATH = "C:\\outils\\ffmpeg-master-latest-win64-gpl\\bin\\ffmpeg.exe";
private static final String OUTPUT_FILE = "C:\\outils\\video\\fichier.mkv";
private boolean testFailed = false;

@Override
protected void failed(Throwable e, Description description) {

    super.failed(e, description);
    testFailed = true;
}

@Override
protected void finished(Description description) {
    super.finished(description);
    if (testFailed) {
        startRecording();

        try {
            Thread.sleep(5000);

        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }
        stopRecording();
    }
}

private void startRecording() {
    String[] command = { FFMPEG_PATH, "-f", "gdigrab", "-framerate", "30", "-i", "desktop", "-c:v", "h264_nvenc", "-qp", "0", OUTPUT_FILE };

    System.out.println(Arrays.toString(command));
    ProcessBuilder builder = new ProcessBuilder(command);
    try {
        builder.start();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

private void stopRecording() {
    String[] command = { "tskill", "ffmpeg" };
    ProcessBuilder builder = new ProcessBuilder(command);
    try {
        builder.start();
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}


  


  }

  


  Does someone have an idea of why it executes well from my cmd but not from my class ?

  


  Thank you in advance
