• Xcode shows error when trying to use FFMpeg

  8 octobre 2019, par Tony.Lee

  I try to use FFMpeg in my iOS project. It’s weird when I import libavcodec/avcodec.h and
  libavformat/avformat.h, Xcode show error : " ’TestViewController’ cannot use ’super’ because it is a root class ".

  Everything is OK before I import the two file above and even I comment these two line codes, it shows this error still. And one more thing, Xcode cannot autocomplete to NSLog when I type nsl.

  Codes can run without any problem, but when writing codes it show those annoying error messages.

• 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

  


• Evolution #3987 : Ne pas supprimer les crédits à la compression CSS

  18 août 2017, par tetue tetue

  Valoriser les crédits dans plugin.xml, c’est super interne (puisque ça concerne une population hyper minoritaire de spipmestres lecteurs de ces infos) mais c’est bien aussi, mais ça ne résout pas le problème qui est pire : on les supprime du code source des pages web !

  L’exclamation dans les commentaires CSS /*! */ marque l’importance et doit échapper à la compression, ce que respecte la minification via LESS et SASS par exemple.

  Ce n’est certes pas un pur dysfonctionnement technique, mais ça pose un problème moral qui me semblait assez grave pour justifier une priorisation.
