Adding srt support in php for mencoder

[Mysoogal]

working, but confused on adding srt support during the mencoder encoding stage.

Code: Select all

<?php



flv_convert_get_thumb('input.avi', 'output.jpg', 'output.ogm');
// code provided and updated by steve of phpsnaps ! thanks
// accepts:
// 1: the input video file
// 2: path to thumb jpg
// 3: path to transcoded mpeg?
function flv_convert_get_thumb($in, $out_thumb, $out_vid)
{
// get thumbnail
$cmd = 'ffmpeg -v 0 -y -i '.$in.' -vframes 1 -ss 5 -vcodec mjpeg -f rawvideo -s 286x160 -aspect 16:9 '.$out_thumb;
$res = shell_exec($cmd);
// $res is the output of the command
// transcode video
$cmd = 'mencoder '.$in.' -o '.$out_vid.' -af volume=10 -aspect 16:9 -of avi -noodml -ovc x264 -x264encopts bitrate=500:level_idc=41:bframes=3:frameref=2: nopsnr: nossim: pass=1: threads=auto -oac mp3lame';
$res = shell_exec($cmd);
}
?>

i havve in /var/www/ list of example.avi and example.srt how would i add support so mencoder also includes the srt subtitles while encoding ? a user at digitalpoint has given this link to https://robot.lk/viewtopic.php?f=67&t=1066

when i visit this page, it shows this code

Code: Select all

$dir = '/path/to/files'; 
if ($handle = opendir($dir)) { 
 while(false!== ($file = readdir($handle))) { 
   if ($file == '.' && $file == '..') continue; 

   // your code here

 } 
 closedir($handle);  
}
  

can somebody help me with it, how to change the big code above ?

thank you

I know your problem and here I write the code for you
This script will convert all the avi files in a given directory to mp4 with subtitles.
Copy this to a file with extension php and place it in the same folder with avi files. (If you want to place it in a different folder, make sure you set it to $dir.

Code: Select all

<?php

$dir = './'; // set to current folder
if ($handle = opendir($dir)) {
    while(false!== ($file = readdir($handle))) {
        
        if ( is_file($dir.$file) ){
            if (preg_match("'\.(avi)$'", $file) ){
                $sub_file = str_ireplace(".avi", ".srt", $dir.$file);
                $thumb_file = str_ireplace(".avi", ".jpg", $dir.$file);
                $out_file = str_ireplace(".avi", ".mp4", $dir.$file);
                flv_convert_get_thumb($dir.$file, $sub_file, $thumb_file, $out_file);
            }
            else{
                continue;
            }
        }
    } 
    closedir($handle);
}


//flv_convert_get_thumb('input.avi', 'input.srt', 'output.jpg', 'output.ogm');
// code provided and updated by steve of phpsnaps ! thanks
// accepts:

function flv_convert_get_thumb($in, $in_sub, $out_thumb, $out_vid){
    // get thumbnail
    $cmd = 'ffmpeg -v 0 -y -i '.$in.' -vframes 1 -ss 5 -vcodec mjpeg -f rawvideo -s 286x160 -aspect 16:9 '.$out_thumb;
    $res = shell_exec($cmd);
    // $res is the output of the command
    // transcode video
    $cmd = 'mencoder '.$in.' -o '.$out_vid.' -sub '.$in_sub.' -af volume=10 -aspect 16:9 -of avi -noodml -ovc x264 -x264encopts bitrate=500:level_idc=41:bframes=3:frameref=2: nopsnr: nossim: pass=1: threads=auto -oac mp3lame';

thank you very much, it works great now don't have to type all in ssh

just wonder why the fonts seem to be so big

can i also add support for sub and idx i think this format is supported in mencoder

Code: Select all

    $sub_file = str_ireplace(".avi", ".srt",.sub",.idx", $dir.$file);  <------- like this ? 
                $thumb_file = str_ireplace(".avi", ".jpg", $dir.$file);
                $out_file = str_ireplace(".avi", ".mp4", $dir.$file);

Use following flags.

Code: Select all

-subfont-text-scale 3.3 -subpos 96

The first one to set the font size to 3.3%. The second setting will move the subtitles up a bit so it is clearly visible on a TV.

So change your command line of mencoder as below.

Code: Select all

$cmd = 'mencoder '.$in.' -o '.$out_vid.' -sub '.$in_sub.' -subfont-text-scale 3.3 -subpos 96 -af volume=10 -aspect 16:9 -of avi -noodml -ovc x264 -x264encopts bitrate=500:level_idc=41:bframes=3:frameref=2: nopsnr: nossim: pass=1: threads=auto -oac mp3lame';

For IDX support:

Code: Select all

                    $sub_file = str_ireplace(".avi", ".srt", $dir.$file);
                    $idx_file = str_ireplace(".avi", ".idx", $dir.$file);
                    $thumb_file = str_ireplace(".avi", ".jpg", $dir.$file);
                    $out_file = str_ireplace(".avi", ".mp4", $dir.$file);
                    flv_convert_get_thumb($dir.$file, $sub_file, $idx_file, $thumb_file, $out_file);
 

Change function prototype as below:

Code: Select all

function flv_convert_get_thumb($in, $in_sub, $in_idx, $out_thumb, $out_vid){
 

MEncoder syntax:

Code: Select all

$cmd = 'mencoder '.$in.' -o '.$out_vid.' -sub '.$in_sub.' -subfont-text-scale 3.3 -subpos 96 -idx '.$in_idx.' -af volume=10 -aspect 16:9 -of avi -noodml -ovc x264 -x264encopts bitrate=500:level_idc=41:bframes=3:frameref=2: nopsnr: nossim: pass=1: threads=auto -oac mp3lame';

thanks for that, but when i changed the code, and went to test it out, i get a white page. when i go back and do refresh no thumbs and no mp4 and no encoding. i wonder if mencoder understand that part

the sub, and idx are from vobsub right ? do mencoder need to be complied with something to understand it ?



i think i missed something i will check again now

[Neo]

Did you place the idx file in the format of example.idx if your avi filename is example.avi?
I don't think you need to re-compile mencoder for this. Lets try!

[Mysoogal]

i see, i was testing it on a file that is being downloaded, maybe that is the issue guess i have to wait until file completes download then test it fully. yes everything is inside ,

http://89.238.172.210/Fatal.Move.2008.DVDRip.XViD-BiEN/
i didnt add the e.php until its complete , i've read somewhere that maybe you only need idx ? since this is like srt and sub not needed is this true

encoding script looking alright ?

Code: Select all

<?php

$dir = './'; // set to current folder
if ($handle = opendir($dir)) {
    while(false!== ($file = readdir($handle))) {

        if ( is_file($dir.$file) ){
            if (preg_match("'\.(avi)$'", $file) ){
                $sub_file = str_ireplace(".avi", ".srt", $dir.$file);
                $thumb_file = str_ireplace(".avi", ".jpg", $dir.$file);
                $out_file = str_ireplace(".avi", ".mp4", $dir.$file);
                flv_convert_get_thumb($dir.$file, $sub_file, $thumb_file, $out_file);
            }
            else{
                continue;
            }
        }
    }
    closedir($handle);
}

looks correct except function call. You missed passing idx file parameter.

Change as below.

Code: Select all

flv_convert_get_thumb($dir.$file, $sub_file, $idx_file, $thumb_file, $out_file);
 

[Mysoogal]

thanks again, i thought when you add // blaaa blaa in php it doesnt get executed

oh jesus lol i find problem

this line was // flv_convert_get_thumb($dir.$file, $sub_file, $idx_file, $thumb_file, $out_file);

so that didnt get executed right lol

something strange happend when i test on example.avi and example.srt

i get this

Code: Select all

Warning: Unexpected character in input: ''' (ASCII=39) state=1 in /var/www/Contact/e.php on line 35

Parse error: syntax error, unexpected T_DNUMBER in /var/www/Contact/e.php on line 35

is this due to the srt having not UTF8 thing ?
