So I have this executable working fine in a Windows 10 dev environment:
$cmd = 'C:/ffmpeg/bin/ffmpeg.exe -i video.mp4 -i audio.mp3 -c:v copy -c:a aac output.mp4';
exec($cmd, $output)
However when I move it into the Ubuntu staging environment and change the path to:
/usr/bin/ffmpeg
there is no response from it.
The following works in the ubuntu terminal
ffmpeg -v, ffmpeg -i, php -v, ...
but there is no response from it from inside php.
Am I missing something here?
I've also tried adding sudo to the above command which seems to make no difference.
(Yes I know I should be developing in the same environment as the staging/prod servers but it's not an option in this specific case).
Absolute path is given instead of relative one
php function to call the python script:
$py_script = escapeshellcmd("/home/manish/anaconda2/bin/python /opt/lampp/htdocs/frontend/master/python_features/audioAnalysis.py featureExtractionFile -i /opt/lampp/htdocs/frontend/master/uploads/rihana.wav -mw 0.5 -ms 0.5 -sw 1 -ss 1 -o /opt/lampp/htdocs/frontend/master/output/rihana_op");
exec($py_script);
Error : Error: file not found or other I/O error. (DECODING FAILED)
Same script runs on terminal and gives the desired output
manish#manish-Vostro-3446:$ /home/manish/anaconda2/bin/python /opt/lampp/htdocs/frontend/master/python_features/audioAnalysis.py featureExtractionFile -i /opt/lampp/htdocs/frontend/master/uploads/rihana.wav -mw 0.5 -ms 0.5 -sw 1 -ss 1 -o /opt/lampp/htdocs/frontend/master/output/rihana_op
Short-term CSV file: /opt/lampp/htdocs/frontend/master/output/rihana_op_st.csv saved
so my question is how can I execute same script via php instead of terminal
For others with this issue. I had the same thing but also a RunTimeWarning about not being able to find ffmpeg. Once I have installed the ffmpeg, then this error also went away.
for mac :
brew install ffmpeg
for linux:
sudo apt install ffmpeg
I have been using wkthmltopdf to convert html to pdf documents on-the-fly on my linux web server. The program originally needed X11 or similar X server to run correctly, but through many requests by developers to have this run on servers without GUI, I am pretty sure it runs a virtual X server in the static version. I have been using the static (stand-alone) version of the program and it works great! I would put the executable file in a folder, and run:
./wkhtmltopdf file1.html file2.pdf
However I would like to install this program system-wide. I used the apt-get install wkhtmltopdf (just installed yesterday) and since I am running on a 64 bit system, I also needed apt-get install ia32-libs. After installation I can find the version like this:
wkhtmltopdf --version
output:

Now when I try to run the program installed via aptitude, I get the following error:
wkhtmltopdf: cannot connect to X server
Does anyone know how I can fix this? I guess this version is missing a virtual X server or something.
or try this (from http://drupal.org/node/870058)
Download wkhtmltopdf. Or better install it with a package manager:
sudo apt-get install wkhtmltopdf
Extract it and move it to /usr/local/bin/
Rename it to wkhtmltopdf so that now you have an executable at /usr/local/bin/wkhtmltopdf
Set permissions: sudo chmod a+x /usr/local/bin/wkhtmltopdf
Install required support packages.
sudo apt-get install openssl build-essential xorg libssl-dev
Check to see if it works: run
/usr/local/bin/wkhtmltopdf http://www.google.com test.pdf
If it works, then you are done. If you get the error "Cannot connect to X server" then continue to number 7.
We need to run it headless on a 'virtual' x server. We will do this with a package called xvfb.
sudo apt-get install xvfb
We need to write a little shell script to wrap wkhtmltopdf in xvfb. Make a file called wkhtmltopdf.sh and add the following:
xvfb-run -a -s "-screen 0 640x480x16" wkhtmltopdf "$#"
Move this shell script to /usr/local/bin, and set permissions:
sudo chmod a+x /usr/local/bin/wkhtmltopdf.sh
Check to see if it works once again: run
/usr/local/bin/wkhtmltopdf.sh http://www.google.com test.pdf
Note that http://www.google.com may throw an error like "A finished ResourceObject received a loading finished signal. This might be an indication of an iframe taking to long to load." You may want to test with a simpler page like http://www.example.com.
This solved the issue for me:
sudo apt-get install xvfb
xvfb-run --server-args="-screen 0, 1024x768x24" wkhtmltopdf file1.html file2.pdf
I tried to do sudo apt-get install wkhtmltopdf but without any success.
Instead I recommend you try:
Download the latest executable (.11 rc1) :
wget https://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
uncompress it :
tar -vxf wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
rename it :
mv wkhtmltopdf-i386 wkhtmltopdf
chmod it to executable :
chmod a+x wkhtmltopdf
place it into /usr/bin :
sudo mv wkhtmltopdf /usr/bin
Just made it:
1- To download wkhtmltopdf dependencies
# apt-get install wkhtmltopdf
2- Download from source
# wget http://downloads.sourceforge.net/project/wkhtmltopdf/xxx.deb
# dpkg -i xxx.deb
3- Try
# wkhtmltopdf http://google.com google.pdf
Its working fine
It works!
I found method to resolve this problem without fake X server.
In newest version of wkhtmltopdf dont need X server for work, but it no into official linux repositories.
Solution for Ubuntu 14.04.4 LTS (trusty) i386
$ sudo apt-get install xfonts-75dpi

User felixhummel got very good solution, but repository with utilite has changed.
Expanding on Timothy's answer...
If you're a web developer looking to use wkhtmltopdf as part of your web app, you can simply install it into your /usr/bin/ folder like so:
cd /usr/bin/
curl -C - -O http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
tar -xvjf wkhtmltopdf-0.11.0_rc1-static-i386.tar.bz2
mv wkhtmltopdf-i386 wkhtmltopdf
You can now run it anywhere using wkhtmltopdf.
I personally use the Snappy library in PHP. Here is an example of how easy it is to create a PDF:
<?php
// Create new PDF
$pdf = new \Knp\Snappy\Pdf('wkhtmltopdf');
// Set output header
header('Content-Type: application/pdf');
// Generate PDF from HTML
echo $pdf->getOutputFromHtml('<h1>Title</h1><p>Your content goes here.</p>');
Update to latest wkhtmltopdf version from SourceForge (0.12 as of this writing). It does not need an X Server to run.
Example for Ubuntu 14.04:
$ cd /tmp/
$ wget -q http://downloads.sourceforge.net/project/wkhtmltopdf/0.12.2.1/wkhtmltox-0.12.2.1_linux-trusty-amd64.deb
$ dpkg -x wkhtmltox-0.12.2.1_linux-trusty-amd64.deb foo

Problem is probably in old version of wkhtmltopdf - version 0.9 from distribution repository require running X server, but current version - 0.12.2.1 doesnt require it - can run headless.
Download package for your distribution from http://wkhtmltopdf.org/downloads.html and install it - for Ubuntu:
sudo apt-get install xfonts-75dpi
sudo dpkg -i wkhtmltox-0.12.2.1_linux-trusty-amd64.deb
wkhtmltopdf > 0.11 doesn't have this X-server issue.
So installing 0.12.2.1 on a linux server.
At first install xvfb server:
sudo apt-get install xvfb
Get needed version of wkhtmltopdf from http://wkhtmltopdf.org/downloads.html
Install wkhtmltopdf:
sudo dpkg -i wkhtmltox-0.12.2.1_linux-trusty-amd64.deb
or install with wget
URL='http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-trusty-amd64.deb'; FILE=`mktemp`; wget "$URL" -qO $FILE && sudo dpkg -i $FILE; rm $FILE
Install dependency (if needed):
sudo apt-get -f install
Create symblic link in /usr/local/bin/:
echo 'exec xvfb-run -a -s "-screen 0 640x480x16" wkhtmltopdf "$#"' | sudo tee /usr/local/bin/wkhtmltopdf.sh >/dev/null
sudo chmod a+x /usr/local/bin/wkhtmltopdf.sh
Now try below and it should work,
/usr/local/bin/wkhtmltopdf http://www.google.com test.pdf
I just figured out that I can simply move the static executable to the /usr/bin/ directory and execute it from anywhere.
solution for Centos7:
yum -y install xorg-x11-fonts-75dpi \
xorg-x11-fonts-Type1 \
&& rpm -Uvh http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-centos7-amd64.rpm
We run into this problem inside docker containers and the above install has wkhtmltopdf with patched QT
It is recommended to use at least 0.12.2.1.
Starting from wkhtmltopdf >= 0.12.2 it doesn't require X server or emulation anymore. You can download new version from http://wkhtmltopdf.org/downloads.html
I did follow the instructions here and made wkhtmltopdf work for me but I would like to offer a bit of perspective which I discovered while doing my own little dance with wkhtmltopdf - xvfb.
This is important because the same reason that causes it to throw the infamous cannot connect to X server error is also causing it to run with sever limitations even if you do provide it a X server. These limitations include not being able to take multiple input sources, set header and footers, etc (check the Reduced Functionality section of the manual).
wkhtmltox by itself doesn't require a X11, however it's making use of QT libraries which do. In newever versions of wkthmltox developers made a patch for QT which allows it to run with a X11.
Currently some versions are built against patched QT and some are not. You can check your version by running wkhtmltopds --version. There should be a line at the end saying Compiled against wkhtmltopdf patched qt.
So, to conclude, if you install and use a version that uses the patched libraries it should work on a linux server without the xvfb server, as I can confirm.
Pay attention: your file could be wkhtmltopdf.sh or wkhtmltopdf, check it on second step
You must copy it into directory : /usr/local/bin, make sur it's executable and add symlink of wkhtmltopdf.sh like :
1- the command :
sudo apt-get install wkhtmltopdf
2 - insert the binary in directory /usr/bin so the browser can't have permission to execute in this directory.
You must copy the wkhtmltopdf.sh to directory /usr/local/bin cause the browser have permission in this directory like:
sudo cp /usr/bin/wkhtmltopdf.sh /usr/local/bin/wkhtmltopdf.sh
3 - After make sur the binary have permission of execution like :
sudo chmod a+x /usr/local/bin/wkhtmltopdf.sh
4 - so now you can test, it's work like:
/usr/local/bin/wkhtmltopdf.sh http://www.google.com google.pdf
it make download the pdf in the current directory in your terminal
5 - Optional
now you can add symlink in your directory /usr/local/bin like
ln -s /usr/local/bin/wkhtmltopdf.sh /usr/local/bin/wkhtmltopdf
Just tell the Qt backend to not use X:
QT_QPA_PLATFORM=offscreen wkhtmltopdf <input> <outfile.pdf>
Download file from this link
Extract it and move executable file(/wkhtmltox/bin/wkhtmltopdf) to /usr/bin/
Rename it to wkhtmltopdf if current name is not wkhtmltopdf. So that now you have an executable at /usr/bin/wkhtmltopdf
Set permissions: sudo chmod a+x /usr/bin/wkhtmltopdf
Install required support packages. sudo apt-get install openssl build-essential xorg libssl-dev
Now, check with wkhtmltopdf http://www.google.com test.pdf
hint: detail information from this link
Just install a version 0.12.4 or higher. This seems to solve the problem.
See How can I install the latest wkhtmltopdf on Ubuntu 16.04?.
If you config wkhtmltopdf for Rails or Somethings in Centos, you can follow these step bellow:
Go to https://wkhtmltopdf.org/downloads.html and copied the link of rpm file.
In centos server bash.
wget link_of_wkhtmltopdf_rpm.rpm
rpm -ivh link_of_wkhtmltopdf_rpm.rpm
which wkhtmltopdf
=> You will get path of wkhtmltopdf.
Setup for wicked_pdf or pdfkit with path in step 4.
This is sample config with wickedpdf. config/initializers/wicked_pdf.rb
if Rails.env != "production"
path = %x[which wkhtmltopdf].gsub(/\n/, "")
else
path = "path_of_wkhtmltopdf_in_step_4"
end
WickedPdf.config = { exe_path: path }
Restart server.
DONE.
For 64-bit Use:
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2
tar xvjf wkhtmltopdf-0.9.9-static-amd64.tar.bz2
sudo mv wkhtmltopdf-amd64 /usr/bin/wkhtmltopdf
sudo chmod +x /usr/bin/wkhtmltopdf
I have a php script that cuts up video. Here are three exec() commands - two execute properly while one does not:
Works:
sudo ffmpeg -i /home/vidserver/videos/$filename.mp4 -ss $ctime -t 00:00:06 -acodec copy -vcodec copy -y /var/vidcache/test$x.mp4
Works:
sudo ffmpeg -i /var/vidcache/test$x.mp4 -qscale:v 1
/var/vidcache/i$x.mpg
Does not work:
sudo ffmpeg -i
concat:"i0.mpg|i1.mpg"
-qscale:v 1 /var/vidcache/output.mpg
/var/vidcache has 777 privs and www-data is in the sudoers file with NOPASSWD (yes, I know - this is just for debug purposes before I lock down security).
When I run the last command from a php script from the command line by itself, it DOES work. (Running as www-data or root.) But when I try to put it in a function called from a web page, it does NOT work.
Any ideas?
This should fix the third exec:
sudo ffmpeg -i "concat:i0.mpg|i1.mpg" -qscale:v 1 /var/vidcache/output.mpg
Here is a good wiki page on how to concat media files in ffmpeg.
Actually, the answer was as stupid as "where does www-data know where to look for files?"
I was assuming a lot with the i0.mpg. It needs a fully qualified directory, obviously.
Anyway, changing the code to look like this worked:
sudo ffmpeg -i concat:"/var/vidcache/i0.mpg|/var/vidcache/i1.mpg"
-qscale:v 1 /var/vidcache/output.mpg
