PHP - calculate remaining time for script.

[QQ_cazo]

My end goal:

 

On like youtube, they show a little thing in the bottom that says "5 mins reaming".

 

 

I have no idea where to start, but i am Using FFMPEG:

 

$format = new Streaming\Format\X264();
$format->on('progress', function ($video, $format, $percentage){
	global $time;
	global $time_init;
	$url_23 = '/home/nrrinc/Desktop/HLS2/2/'.$time.'/';
    // You can update a field in your database or can log it to a file
    // You can also create a socket connection and show a progress bar to users
    //echo sprintf("\rTranscoding...(%s%%) [%s%s]", $percentage, str_repeat('#', $percentage), str_repeat('-', (100 - $percentage))).'';
    $myfile = fopen($url_23."txt.status", "w") or die("Unable to open file!");
    //$txt = sprintf("\rTranscoding...(%s%%) [%s%s]", $percentage, str_repeat('#', $percentage), str_repeat('-', (100 - $percentage))).'';
	$txt = sprintf("%s%", $percentage, str_repeat('#', $percentage),).''.'<br>';
    fwrite($myfile, $txt);
    fclose($myfile);

### I want to echo how much time is remaining til the render is done
});

Total file size (MBs) minus MBs rendered = MBs Remaining

MBs Remaining divided by MB per second = Time remaining

MBs rendered divided by (Total file size (MBs) divided by 100) = Progress Percentage

 

Additionally you will have to define the following terms:

Total file size (MBs)

MBs rendered

MB per second

also as a suggestion, if you have your own server or  your web hosting offers this, consider using memcached or a memory table in your mysql instead of updating text files.

memcached - https://memcached.org/ - is a key:value list kept in memory ... so you can create a unique key based on the path of the file and the value can be the information you want to access later encoded in some format , for example json encoded.

memcached will automatically prune the oldest least accessed records when the memory it has allocated gets full so you don't need to worry about deleting key:value pairs from memory (but you could)

With a memory table in mysql, you could just add a "last_updated" column and store the time there (jut time() result would be plenty)  and once an hour or so you could run a query "delete all records older than 48 hours " or whatever period you want.

in PHP-FFMpeg, how could this be done? (i know how to get the total file size, but how to get the MBs rendered?)

 

i can provide the full code if needed
