• Anomalie #2843 (Nouveau) : Ajout de tous les documents d’un dossier dans upload : ajout multiple

  6 septembre 2012, par deor 971

  Lors de l’ajout de tous les documents d’un dossier dans upload, l’ajout, d’une part, ne se termine pas (ou alors je n’ai pas eu la patience d’attendre), et quand on retourne sur la page de l’article où on ajoute les documents, on remarque que les documents ont été ajoutés plusieurs fois (jusqu’à 7 (...)

• How can close file using popen ?

  31 mai 2021, par Yongqi Z

  I write a cpp server to process audio file using ffmpeg, and use rm -rf audio_folder to delete the completed files in the server. There are original audio file and converted audio file using ffmpeg under audio_folder.

  


  1 My operation steps

  


  I use ./ffmpeg -i /audio_folder/origin.wav -ar 8000 -acodec pcm_s16le -ac 1 -fflags +bitexact -ignore_unknown -vn -flags:v +bitexact -flags:a +bitexact -map_metadata -1 /audio_folder/coverted.wav to covert audio files.

  


  I use rm -rf audio_folder to delete completed files.

  


  code likes this :

  


  std::string cmd = "./ffmpeg -i /audio_folder/origin.wav -ar 8000  /audio_folder/coverted.wav";
FILE *fp = popen(cmd.c_str(), "r");
fprintf(stderr, "cmd:%s", cmd.c_str());
if (fp != NULL) {
    char output[2048] = {0};
    while (fgets(output, sizeof(output), fp) != NULL) {
        int len = strlen(output);
        if (output[len - 1] == '\n') {
            output[len - 1] = 0x00;
        }
        fprintf(stderr, ":%s", output);
    }
    pclose(fp);
   fp = NULL;
} else {
    return -1;
}


  


  2 My question

  


  I find this rm commond can not release the space, as I get different results from df and du, the result from du smaller than result from df.
I use lsof | grep deleted and get some results like this :

  


  audioServer ... 11510667 /audio_folder/origin.wav (deleted)

  


  I wonder it because the server is not closed and it holds the handle of the deleted file, so that the space is not released.

  


  3 Expected

  


  How can I release the space without close the server ? Should I close the handle of origin audio file ? but I do not have the handle, I just send this file to ffmpeg and get converted file.
