  • FFmpeg audio dont work in converted videos

    28 octobre 2013, par Bar Cumberworth

    NOTICE : when i convert videos via terminal and download them from ftp into pc the audio works fine. I use :

    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";
    
                $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
    
                $ffmpeg_command = 'ffmpeg -i '.$convert_source.' -acodec libmp3lame -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$converted_file;
    
                echo exec($ffmpeg_command);
    
                $sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
    
                $result = @mysql_query($sql);

  • ffmpeg after converting avi to mp4 need wait till video loads in flash player 100% otherwise video is buffering

    So if fixed all issues with my ffmpeg journey now I just need that after converting videos they play in flash player instantly and no need to wait till video loeaded 100% I use :

    if ($success_msg) {

    $ext = strtolower($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";
    
        $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
    
        $ffmpeg_command = 'ffmpeg -i '.$convert_source.' -acodec libfaac -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$converted_file;
