  • Debian ffmpeg working in terminal but not in php

    30 octobre 2013, par user2938660

    I reinstalled ffmpeg on debian and php exec doesn't work for me anymore when called from php. I'm using :

    if ($success_msg) 
    
{
    
    $tmp_parts = explode('.', $file['name']);
    
    $ext = array_pop($tmp_parts);
    
    $ext = strtolower($ext);
    
    if($ext == "avi" && $convert_avi == true)
    
    {
    
        $convert_source = _VIDEOS_DIR_PATH.$new_name;
    
        $conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
    
        //$conv_name2 = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
    
        $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
    
        //$fastarted_file  = _VIDEOS_DIR_PATH.$conv_name2;
    
        $ffmpeg_command = 'ffmpeg -i '.$convert_source.' -r 20 -g 40 -acodec libfaac -ar 44100 -ab 96k -vcodec libx264 -sameq '.$converted_file;
    
        //$faststart_command = "qt-faststart ".$converted_file." ".$fastarted_file;
    
        shell_exec($ffmpeg_command);
    
        unlink($convert_source);
    
        //shell_exec($faststart_command);
    
        $sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
    
        $result = @mysql_query($sql);
    
}
    
echo $success_msg;

    this code to convert videos and ffmpeg output is :

  • Extract files from mpeg video

    28 octobre 2013, par A Dark Divided Gem

    Videos created with Camtasia can be shared on the web by exporting the project for the TechSmith Smart Player. The video is exported in the "H264 - MPEG-4 AVC (part10) (avc1)" codec and the export also includes other custom XML, JavaScript and SWF files used by the TechSmith Smart Player.

    These custom files are also "burnt" into the video itself. For example the contents of the XML file can be viewed when opening the MP4 video in a text editor. This allows other services to only ask for the MP4 file when uploading Camtasia videos.

    Therefore my question is how do you extract text and binary files from a MP4 video file ? For this project I am limited to Java but I am happy to call an external executable as well.

    I tried the "-dump_attachment" option in FFmpeg but that didn't work and I am out of ideas.

  • FFMpeg metadata issue

    whenever I run ffmpeg -i filename it returns something like this :

    Except when I run it from java using :

    ProcessBuilder pb = new ProcessBuilder(new String[]{"ffmpeg", "-i", "filename"});
    
    pb.redirectErrorStream(true);
    
    try{
    
        Process p = pb.start();
    

    
        BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
    
        String bs = "";
    
        while(br.readLine() != null){
    
            bs += br.readLine();
    
            bs += "\n";
    
        }
    
        return bs;
    
    }catch(IOException e){
    
        e.printStackTrace();
    
    }

    it gives me this :

    How come when I run it from cmd I get way more data ? Can anybody tell me what I am doing wrong ?
