YouTube-to-MP3 conversion - PHP class and script

[chump2877]

Your AJAX response text indicates that you are getting an error in ffmpeg_progress.php -- most likely your FFMPEG command is not generating a log file. Without a log file, no conversion progress bar can be generated, and the entire process will stall (as it's doing).

The log file is generated by the code in red:

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

Few things to try:

1) Check that 'logs/' and 'mp3/' directories have write privileges

2) Check to make sure cURL is not "hanging up" on exec_ffmpeg.php before the full FFMPEG command can be executed. Try increasing the number of seconds in this line in YouTubeToMp3Converter::GenerateMP3():

PHP Code:

curl_setopt($ch, CURLOPT_TIMEOUT, 1); 


3) Check your 'logs/' directory. Are there text files in there?

4) Check your 'mp3/' directory. Are there mp3 files in there?

Log file are correctly located in logs folder, mp3 file in mp3 folder, permissions on folder 777

curl_setopt($ch, CURLOPT_TIMEOUT, 1); tested

same things

no error on error_log from apache

don't undertand

[chump2877]

Paste the contents of the log file that is generated.

this is the log file chum

I don't see any problems in the log file.

Try to debug different PHP variables inside of ffmpeg_progress.php (that are causing $error == 1).

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

PHP Code:

echo $newLogLength . "|" . $progress . "|" . $conversionSuccess . "|" . $error . "|" . $logFile; 


(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. Post the values of those variables here.

[bedo1975]

chump, I've modified the file, and add your command line to see variables error, but nothing appears on the web page, in firebug I've this :

I think it's correct no ?

I've this in post ffmeg_progress in firebug :

you can change the ffmpeg command line in :

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

I don't know exactly which variables you are outputting there...time for bed for me....I'll take another look tomorrow

[bedo1975]

okay, I've reuploaded a fresh script without any modification, and I think that I have throught the error :

you can see with the fresh script, the variable logLength in the post ffmpeg_progress is empty egals to " 0 " so I think it's the error

Wait for you see !

[bedo1975]

Again me

2792|0|2|2

I looked at this, the first number is le length of log file => ok

but the second number is normaly the % progresse

so in firebug he was always at 0 and jquery process are loop infinity

[chump2877]

Ok, $progress is determined in ffmpeg_progress.php as follows:

PHP Code:

$progress = round(($currentTime / $totalTime) * 100); 


So adjust your echo line in the same file as follows:

PHP Code:

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


Run the script and check the various AJAX responses in FireBug to see what those variables are evaluating as. That could give you a hint as to what the problem is.

[bedo1975]

okay it's do :

result :

$newLogLength . "|" . $progress . "|" . $conversionSuccess . "|" . $error . "|" .
2428 | 0 | 2 | 2 |

$currentTime . "|" . $totalTime;
0 | 465.23

I see the $currentTime variable are always eguals to ' 0 ' it's the coz i think

[bedo1975]

$currentTime = (float)end($times[1]);

this is my problem with the float instruction
