그래서 나는 그가 나에게 간부 정지 PHP 스크립트에게 몇 가지를 물어 내게

You can't get the progress directly if you are using exec, because the php script is stopped until ffmpeg closes. (Because exec returns the whole execution output) 

You should use popen, for being able to get the output from the process in real time (without reading any file) for parse and show the progressbar 

Here is a example for get the output: 

When you get the progress info from ffmpeg, you can use your code for parse it and show your progressbar

,369을주지 않을

이는 FFmpeg ProgressBar의 좋은 무엇 때문에

<?php 

$handle = popen ("ffmpeg.exe -i files/fz.mp4 -ab 192k files/vdf.mp3 2>&1 ", 'r'); 
$handles = (string)$handle; 
$line = ""; 

while (false !== ($char = fgetc($handle))) 
{ 
    if ($char == "\r") 
    { 
    // You could now parse the $line for status information. 
    echo "$line\n"; 
    $line = ""; 
    } else { 
    $line .= $char; 
    } 
    ob_flush(); 
    flush(); 
} 
pclose ($handle); 


    //get duration of source 
    preg_match("/Duration: (.*?), start:/", $handles, $matches); 

    $rawDuration = $matches[1]; 

    //rawDuration is in 00:00:00.00 format. This converts it to seconds. 
    $ar = array_reverse(explode(":", $rawDuration)); 
    $duration = floatval($ar[0]); 
    if (!empty($ar[1])) $duration += intval($ar[1]) * 60; 
    if (!empty($ar[2])) $duration += intval($ar[2]) * 60 * 60; 

    //get the time in the file that is already encoded 
    preg_match_all("/time=(.*?) bitrate/", $handles, $matches); 

    $rawTime = array_pop($matches); 

    //this is needed if there is more than one match 
    if (is_array($rawTime)){$rawTime = array_pop($rawTime);} 

    //rawTime is in 00:00:00.00 format. This converts it to seconds. 
    $ar = array_reverse(explode(":", $rawTime)); 
    $time = floatval($ar[0]); 
    if (!empty($ar[1])) $time += intval($ar[1]) * 60; 
    if (!empty($ar[2])) $time += intval($ar[2]) * 60 * 60; 

    //calculate the progress 
    $progress = round(($time/$duration) * 100);

난 스탠드에서 그나마 제는 popen 스크립트

이 간부 또는

그렇게 내게주세요는 popen이다는 FFmpeg 실시간에 대한 힌트를 진행 막대

진보 표시 줄에 좋은 점

은 html5 진행률 막대

또는 자바 스크립트 진행 표시 줄

체크 아웃 한 (PHP의는 FFmpeg 변환) : https://github.com/jmalinens/wap4 내가 기억과 관련된 부분을 찾기 위해 노력할 것입니다 나는 당신에게 영감을 줄 것이다 희망 –

내 접근 방식은 여기 내 오래된 프로젝트 중 하나에서 약간 수정 된 코드는이

$sCmd = "ffmpeg -i infile.mp4 ... -report outfile.mp4 > /var/log/ffmpeg.log"; 
$proc = popen($sCmd." 2>&1", "r"); 
$read = fread($proc, 2096); 
pclose($proc);

같은했다. 내 프로젝트의

<?php 
//get so far encoded time 
public function getEncodedTime(){ 

    $FFMPEGLog = file_get_contents('ffmpeg.log'); 
    $times  = explode('time=', $FFMPEGLog); 
    $ctime  = count($times)-1; 
    $timed  = explode(' bitrate=', $times[$ctime]); 
    //print_r($timed); 
    $nEncTime = $timed[0]; 
    list($h, $m, $s) = explode(":", $nEncTime); 
    $s = ceil($s); // 21.40 seconds => 22 seconds 
    $nEncTime = hms2sec($h, $m, $s); 

    return $nEncTime; 

} 

//covert H:i:s time to seconds 
public function hms2sec ($h, $m, $s) { 

    //list($h, $m, $s) = explode (":", $hms); 
    $seconds = 0; 
    $seconds += (intval((string)$h) * 3600); 
    $seconds += (intval((string)$m) * 60); 
    $seconds += (intval((string)$s)); 
    return $seconds; 

} 


//get total length of file 
public function getTotalTime() 
{ 
    $play_time_sec = 0; 

    $lines = file('ffmpeg.log'); 
    foreach ($lines as $line_num => $line) { 
     if(strpos($line, 'Duration') !== false) { 
      $line = explode("Duration: ", $line); 
      $line = explode(",", $line[1]); 
      $line = explode(":", $line[0]); 

      $play_time_sec = 0; 
      $play_time_sec += intval((string)$line[0]) * 60 * 60; // hour 
      $play_time_sec += intval((string)$line[1]) * 60; // minute 
      $play_time_sec += intval((string)round($line[2])); // second 
      break; 
     } 
    } 

    return $play_time_sec; 
} 


//get percents completed: 
public function getPercentsComplete() 
{ 

    $sFileContents = file_get_contents('ffmpeg.log'); 
    if(stripos($sFileContents, 'No more inputs to read from, finishing') !== false) { 
     return 100; 
    } 

    $nTotalTime = getTotalTime(); 
    $nEncodedTime = getEncodedTime(); 

    if($nEncodedTime <= 0) 
     return 0; 

    if($nEncodedTime >= $nTotalTime) 
     return 100; 

    $nPercentsComplete = round(($nEncodedTime/$nTotalTime)*100); 

    return $nPercentsComplete; 
}
