какова хорошая функция php для работы с ffmpeg и индикатором выполнения

Я спрашиваю о ffmpeg и progressbar

Я использовал функцию exec с ffmpeg и вывел результат в txt-файл

и используя некоторый код, который я нашел здесь, чтобы

поэтому я спрашиваю кого-то, он сказал мне скрипт exec stop php и никогда не дает мне

 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

это мой всплывающий скрипт

 <?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); echo '<BR><BR>¡Su video fue convertido correctamente! <BR><BR>Link al archivo:'; echo "Duration: " . $duration . "<br>"; echo "Current Time: " . $time . "<br>"; echo "Progress: " . $progress . "%" . "<br>"; //////////////////////////////////////my coed ////////////////////////////////////////////// ?>

поэтому я не подставил то, что хорошо для ffmpeg progressbAR

является exec или popen

поэтому, пожалуйста, дайте мне подсказки для ffmpeg в реальном времени progressbar

что хорошо для progressbar

html5 индикатор выполнения

или индикатор javascript

Мой подход был примерно таким

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

Вот немного модифицированный код из одного из моих старых проектов. Надеюсь, это даст вам некоторое вдохновение:

 <?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; }
