YouTube-to-MP3 conversion - PHP class and script

[chump2877]

sudo apt-get install ffmpeg libavcodec-extra-52

...per the forum post that I linked to...you may need to uninstall ffmpeg and reinstall with that command (which gets you ffmpeg and the codecs)? I don't know --I'm just guessing....

I think that we could buy a commercial Ubuntu VPS for a month from http://solarvps.com/ for paypal $1 and try to install working script, then write a complete guide.

Well, I could just install another copy of Ubuntu into another VM, and this time configure everything via the CLI...maybe I'll do that at some point in the future....I don't have the time for it right now....

But I agree, it would be ideal to have a list of commands for people...It would be easier to install into a commercial VPS as well as other flavors of Linux that way...Any volunteers?

Everething looks ok, mp3 files are generated to mp3 folder bat download links not showing, nothing heppend.

Check link: http://uhuuu.com/u2/

I dont know what is problem...!!!

[chump2877]

cana888, that is very strange and I can't reproduce the issue here.

Try the following:

1) Check that you have at least PHP v5.3

2) You are running this in Ubuntu 11.04 instead of 11.10 (as I am), so you might have an incompatible package installed. Or perhaps a package (or package dependency) is missing?

3) You seem to be experiencing some output buffering issues. Try replacing the following code (in all files except inside YouTubeToMp3Converter::UpdateVideoDownloadProgress()):

PHP Code:

flush(); 


...with...

PHP Code:

ob_end_flush();
ob_flush();
flush(); 


4) Try to debug different PHP variables inside of ffmpeg_progress.php. While your log file size increases, your percent progress never goes above zero.

For example, to debug $totalTime and $currentTime in ffmpeg_progress.php, change the last line of that file to read:

PHP Code:

echo $newLogLength . "|" . $progress . "|" . $conversionSuccess . "|" . $error . "|" . $totalTime . "|" . $currentTime; 


(Additional variables must appear at the end of the echo statement separated by pipe characters.)

Then check the AJAX response text in FireBug (in Firefox) to see what those variables are (and why their division always equals zero).

5) Comment out this line in index.php, like so:

PHP Code:

    // Execution settings 
    ini_set('max_execution_time',0); 
    //ini_set('display_errors',0); 


To see what PHP errors (if any) that you are getting?

1) It seems ffmpeg-php is not successfully and/or correctly installed with PHP because there is no ffmpeg section in php.ini: http://3.bp.blogspot.com/-j4E4kFLqXI...40/Capture.JPG.

2) Make sure that this is the correct location of FFMPEG:

PHP Code:

const _FFMPEG = '/usr/local/bin/ffmpeg'; 


3) Did you do this??:

4) Try to debug different PHP variables inside of ffmpeg_progress.php. While your log file size increases, your percent progress never goes above zero.

For example, to debug $totalTime and $currentTime in ffmpeg_progress.php, change the last line of that file to read:

PHP Code:
echo $newLogLength . "|" . $progress . "|" . $conversionSuccess . "|" . $error . "|" . $totalTime . "|" . $currentTime;
(Additional variables must appear at the end of the echo statement separated by pipe characters.)

Then check the AJAX response text in FireBug (in Firefox) to see what those variables are (and why their division always equals zero).

If you don't know how to use Firebug Console tab, then it's time to learn how:

-- http://stackoverflow.com/questions/5...g-ajax-request

4) Did you do this?:

5) Comment out this line in index.php, like so:

PHP Code:
// Execution settings
ini_set('max_execution_time',0);
//ini_set('display_errors',0);
To see what PHP errors (if any) that you are getting?

5) Did you do this??:

3) You seem to be experiencing some output buffering issues. Try replacing the following code (in all files except inside YouTubeToMp3Converter::UpdateVideoDownloadProgress()):

PHP Code:
flush();
...with...

PHP Code:
ob_end_flush();
ob_flush();
flush();

It seems to me that you didn't try to do some of the things that I suggested. I can't help you if you don't follow my instructions.

Nicely job, but I have some bugs.

in fact the script download and encode correctly the flv that I choose but, the progress bar downloading are okay, but the progress bar for converter don't appears. and I have debug this I have this error :

do you know where this bug provide ?

thanks

That warning message appears to be generated by this line in YouTubeToMp3Converter.class.php:

PHP Code:

$percent = round($downloaded/$downloadSize, 2) * 100; 


The easiest way to get rid of the warning is by either turning off error reporting (which you should be doing anyway for a production-grade application) or doing the following:

PHP Code:

$percent = @round($downloaded/$downloadSize, 2) * 100; 


But that PHP warning should not be causing your code to malfunction. And, in fact, that code has nothing to do with the "conversion" progress bar (instead, it helps build the "download" progress bar).

So you should focus your troubleshooting efforts elsewhere. Perhaps try some of the troubleshooting strategies that I've already outlined in this thread.

yes I look with firebug, but i don't see any errors.

So in the youtube class if I keep this :

$exec_string = parent::_FFMPEG.' -i '.$this->GetTempVidFileName().' -y -acodec libmp3lame -ab '.$quality.'k '.$this->GetSongFileName() . ' 2> logs/' . $this->_uniqueID . '.txt';


the curl fonction don't work, so if I remplace with :

= 'ffmpeg -i '.$this->GetTempVidFileName().' -y -acodec libmp3lame -ab '.$quality.'k '.$this->GetSongFileName() . ' 2> logs/' . $this->_uniqueID . '.txt';

curl run correctly, but the progress conversion not show too with this modification

I've verify, in config and my contant _FFMPEG are correctly /usr/local/bin/ffmpeg

I search , I search but

[chump2877]

If constant _FFMPEG equals '/usr/local/bin/ffmpeg', then your FFMPEG command should read:

PHP Code:

$exec_string = '/usr/local/bin/ffmpeg -i '.$this->GetTempVidFileName().' -y -acodec libmp3lame -ab '.$quality.'k '.$this->GetSongFileName() . ' 2> logs/' . $this->_uniqueID . '.txt';

okay chump, with firebug this is that I'm detected :

data : "uniqueId=1329924692_4f450a54152a66.99442542&logLength=" + conversionLogLength + "&mp3File=" + encodeURI(songFile),


as you see, the uniqueId is not empty but the rest converisonLogLength etc ... are empty ! is it normal ?

[bedo1975]

sorry chump, but I just see this in firebug :

the AJAX requests in Firebug continue on indefinitely even after the page has stopped loading. Mark : jquery.min.js

What is the video you are trying to convert? I can try to convert it here and see if it works.

What kind of server setup do you have?

Can you at least temporarily put your code online, give me the URL, and let me have a look at the AJAX requests?

[bedo1975]

hi chump, this is the url, the video that I can to convert is, the url of example.

http://onlinemyclip.com/Dev3/phptube2/

I use a linux server based on centos

ffmpeg-php are correctly enabled is the phpinfo
