  • How to specify the audio path for ffmpeg and how to conduct a silence removal using ffmpeg

    15 octobre 2020, par Leo

    I wish to conduct a silence removal for wav files.

    


    import ffmpeg
inPath = "/home/test/Speech/Wang/dataset/testsets/disgust/0_002_00_021_F002_d.wav"
outPath = "/home/test/Speech/Wang/dataset/testsets/disgust/0_002_00_021_F002_d_trimed.wav"
ffmpeg -i inPath -af silenceremove=0:0:-50dB outPath


    


    Error occurred.

    


      File "", line 3
    ffmpeg -i inPath -af silenceremove=0:0:-50dB outPath
                   ^
SyntaxError: invalid syntax


    


    How should I assign the path ?

    


    The question is that why we set the threshold to a negative value ?

    


  • PHP Sort Order Process Codeiginiter

    5 août 2017, par Alan El-nino Malmsteen

    i use php codeigniter to manage video using FFMPEG, but i dont know how to delete original video after convertion successful.

    if(!($_FILES["upload_video"]["type"] == "video/mp4"))
    
    {
    
    $prename = $r.'.'.$ext;
    
    $video = $prename.'.mp4';
    
    $directory_path  = "/home/templates/videos/".$prename;
    
    $directory_path_full = "/home/templates/videos/".$prename;
    
    exec("ffmpeg -i ".$directory_path_full." ".$directory_path.".mp4"); 
    

    
    // Delete original format video
    
    $this->load->helper("file");
    
    unlink($directory_path_full); 
    

    
    }else{
    
    $video = $r.'.'.$ext;
    
    }

    When i use "unlink" it work good to delete file, but the video is corrupt (maybe php directly delete it when converting progress)
    So, can you help me to create sort order php process for this case ?

  • write video in OpenCV FOURCC codec

    25 juillet 2018, par burak akdemir

    I am trying to save the results of YOLO to .avi file. Having already seen this post... (I even asked the question there) I could NOT find any solution. Here is the code in which I am trying to save the .avi.

    {
    
    CvSize size;
    
    size.width = disp->width;
    
    size.height = disp->height;
    

    
    static CvVideoWriter* output_video = NULL;    // cv::VideoWriter output_video;
    
    if (output_video == NULL)
    
    {
    
        printf("\n SRC output_video = %p \n", output_video);
    
        const char* output_name = "test_dnn_out.avi";
    
        output_video = cvCreateVideoWriter(output_name, CV_FOURCC('D', 'I', 'V', 'X'), 25, size, 1);
    
        printf("\n cvCreateVideoWriter, DST output_video = %p  \n", output_video);
    
    }
    
    cvWriteFrame(output_video, disp);
    
}

    Trying plenty of codecs ( changing CV_FOURCC('D', 'I', 'V', 'X') ) I get errors below :

    Here is my setup

    -ubuntu 16.04

    -opencv 3.3.0

    -ffmpeg version 2.8.14

    In my opinion, the problem is very likely to be about codecs. Because people solved the same problem by using different codecs. Even though I tried many codecs and have ffmepeg installed correctly I could NOT find any solution. So what should I do ? Looking forward to your replies...
