encoding not start and image not being grabbed

mysoogal · May 19, 2009

can someone tell me why it's not encoding and grabbing image files ? it's connected to mysql but the ffmpeg and mencoder command are not being followed.

3 files hold the process, upload.htm, upload.php,fvec.php

alright here is the source code for upload.htm

now this fvec.php the ffmpeg and mencoder are not started, also the duration of video is not taken. im really not sure whats up with this.

code for fvec.php the encoding script with mysql insert

#1 try echoing the $res from the shell_exec's to see what happening

#2 Check the server logs

Has this ever worked before ?

so you have full access to the server ?

mysoogal · May 19, 2009

this is the original code provided by sothinkmedia in their php samples.

the issue here is that fvec is a paid version software and is a wrapper around ffmpeg mencoder mplayer, so i really don't want to pay the above 300 pounds license fee to access open source projects such as ffmpeg or mencoder.

so I'm trying to bypass their fvec code and replace it with my own ffmpeg and mencoder code.

<?php

// encoding may take a few minutes.

set_time_limit(1800);

// disable output buffering so we can send the encoding progress to the browser.

ob_implicit_flush(true);



include("db.php");

    $TimeArray = NULL;

	if(strlen($Duration) > 0) 

	{

		$TimeArray = explode(":", $Duration);		

		if(count($TimeArray) > 2)

		{

			return ((int)$TimeArray[0]) * 3600 + ((int)$TimeArray[1]) * 60 + ((int)$TimeArray[2]);

		}

	}

}



function GetCurPath()

{

	$curpath = $_SERVER["DOCUMENT_ROOT"].$_SERVER["PHP_SELF"];

	$index = strrpos($curpath, "/");

	if($index != 0)

		$curpath = substr($curpath, 0, $index);

new friend of mine from phpsnaps helped me modified the fvec for ffmpeg and mencoder, this is what he had to say about this, but im not sure how i should use this information to correct things. since im very new to php

heir code uses the $ExecResult to check for encoding error, you should set the output of your encoding code to go there, so that
the existing flow of the code remains the same.

The errors you get have to do with the way the variables are presented in a string.

The correct way is to concetate string with the dot, not like this: 'a big string with a $variable';

After you see the code below, you should check what is the output of the convert function ($ExecResult).

Because: if($ExecResult == 0) that means the conversion was successful (well, at least with the old code).

Which means, if the function flv_convert_get_thumb() runs with success but it doesn't return 0, the script will give you error, even if the

conversion happened!

#1 try echoing the $res from the shell_exec's to see what happening

#2 Check the server logs

Has this ever worked before ?

so you have full access to the server ?

okay so no it hasn't worked before..

Have you checked the logs and echoed the $res ?

EDIT: also is this on your own PC or a shared server?

mysoogal · May 19, 2009

yes its on my development machine, ubuntu 8.10 with everything installed

it works on the original code but with the replaced code, it doesn't seem to start the ffmpeg to get image and encoding not starting also.

the res i believe i used 1 to show encoding error. but still same doesn't give exactly the error since the output error is for the fvec. ???

MadTechie · May 20, 2009

Okay this was my first post in this topic

#1 try echoing the $res from the shell_exec's to see what happening

#2 Check the server logs

Has this ever worked before ?

so you have full access to the server ?

So far i know this

#1 try echoing the $res from the shell_exec's to see what happening -- unknown
#2 Check the server logs -- unknown

Has this ever worked before ? - no

so you have full access to the server ? - yes

and from the start you said

it inserts data into mysql database but only image and encoded video are not being done

and this is from your own code

    // get thumbnail
    $cmd = 'ffmpeg -v 0 -y -i '.$FileName.' -vframes 1 -ss 5 -vcodec mjpeg -f rawvideo -s 286x160 -aspect 16:9 '.$FileName_JPG;

    $res = shell_exec($cmd);
    // $res is the output of the command

So

// $res is the output of the command

Now I know if you make a call to a problem and that program isn't found you get an error, this error is found in the server logs and in the output of the command.. however these are the two things you have yet to tell me!

With all that in-mind i am going to guess and say you need to add the path to ffmpeg and mencoder into the code.

mysoogal · May 20, 2009

so just below, i should add my ffmpeg and mencoder code ? but isn't this already used by this cmd line above.

here is the whole project. mysoogals.zip - 1017.7 Kb if you want to check out for your self. and few other files like vlc player. i will try to add the mencoder code below hope it works.

 $res = shell_exec($cmd);
    // $res is the output of the command

if you want to test it out, fully please let me know. i believe maybe the theme not show up in index.php
