  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

    11 mars 2021, par lorenzotarquini

    I'm making a simple mp3 downloader using youtube-dl. During my tests with python, everything works, I only had a problem when I saw an error that said 'ffprobe/avprobe and ffmpeg/avconv not found, please install one', solved including ffmpeg.exe and ffprobe.exe in Scripts folder but then i wrote the exe file with pyinstaller, and i got the same error i found before, IDK how to solve it, can someone help me ?. this is the spec file generated :

  • FFMpeg process created from Java on CentOS doesn't exit

    21 juin 2017, par Donz

    I need to convert a lot of wave files simultaneously. About 300 files in parallel. And new files come constantly. I use ffmpeg process call from my Java 1.8 app, which is running on CentOS. I know that I have to read error and input streams for making created process from Java possible to exit.

    My code after several expirements :

        private void ffmpegconverter(String fileIn, String fileOut){
    
    String[] comand = new String[]{"ffmpeg", "-v", "-8", "-i", fileIn, "-acodec", "pcm_s16le", fileOut};
    

    
    Process process = null;
    
    BufferedReader reader = null;
    
    try {
    
        ProcessBuilder pb = new ProcessBuilder(comand);
    
        pb.redirectErrorStream(true);
    
        process = pb.start();
    

    
        //Reading from error and standard output console buffer of process. Or it could halts because of nobody
    
        //reads its buffer
    
        reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
    
        String s;
    
        //noinspection StatementWithEmptyBody
    
        while ((s = reader.readLine()) != null) {
    
            log.info(Thread.currentThread().getName() + " with fileIn " + fileIn + " and fileOut " + fileOut + " writes " + s);
    
            //Ignored as we just need to empty the output buffer from process
    
        }
    
        log.info(Thread.currentThread().getName() + " ffmpeg process will be waited for");
    
        if (process.waitFor( 10, TimeUnit.SECONDS )) {
    
            log.info(Thread.currentThread().getName() + " ffmpeg process exited normally");
    
        } else {
    
            log.info(Thread.currentThread().getName() + " ffmpeg process timed out and will be killed");
    
        }
    

    
    } catch (IOException | InterruptedException e) {
    
        log.error(Thread.currentThread().getName() + "Error during ffmpeg process executing", e);
    
    } finally {
    
        if (process != null) {
    
            if (reader != null) {
    
                try {
    
                    reader.close();
    
                } catch (IOException e) {
    
                    log.error("Error during closing the process streams reader", e);
    
                }
    
            }
    
            try {
    
                process.getOutputStream().close();
    
            } catch (IOException e) {
    
                log.error("Error during closing the process output stream", e);
    
            }
    
            process.destroyForcibly();
    
            log.info(Thread.currentThread().getName() + " ffmpeg process " + process + " must be dead now");
    
        }
    
    }
    
}

    If I run separate test with this code it goes normally. But in my app I have hundreds of RUNNING deamon threads "process reaper" which are waiting for ffmpeg process finish. In my real app ffpmeg is started from timer thread. Also I have another activity in separate threads, but I don’t think that this is the problem. Max CPU consume is about 10%.

    Here is that I usual see in thread dump :

    "process reaper" #454 daemon prio=10 os_prio=0 tid=0x00007f641c007000 nid=0x5247 runnable [0x00007f63ec063000]

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
    
    at java.lang.Thread.run(Thread.java:745)

    What am I doing wrong ?

    UPD :
    My app accepts a lot of connects with voice traffic. So I have about 300-500 another "good" threads in every moment. Could it be the reason ? Deamon threads have low priority. But I don’t beleive that they really can’t do their jobs in one hour. Ususally it takes some tens of millis.

    UPD2 :
    My synthetic test that runs fine. I tried with new threads option and without it just with straigt calling of run method.

}

    UPD3 :
    Sorry, I forgot to notice that I see the work of all these process - they created new converted files but anyway don’t exit.
