Installing missing libraries on Linux (FME 2015 and Earlier). These symptoms indicate a missing shared library which is commonly present on Linux systems. Rather than just JPEG. Resolution The missing library can be installed from your distribution's repositories. If you attempted to run the FME Workbench GUI directly, please do so again.

How do I install the python imaging library (PIL) on Ubuntu?

I tried doing

but now when i run python selftest.py(a script I got from somewhere on the http://pythonware.com/products/pil/ website)I get (among other warning messages):

Have I somehow messed up the PIL -- how do I fix that?

Is maybe the PIL just fine, but that 'selftest.py' is not really the right program for checking to see if PIL is installed properly -- how else can I tell if PIL is installed properly or not?

(I'm using Ubuntu 12.04 LTS 'Precise Pangolin').

(What I'm ultimately trying to do is to add a 2D barcode generator to some python code,and all the 2D barcode generators I could find that were written in python all seemed to use the PIL).

Something similar happened to me, I solved this way

And try there installing via pip install PIL.

More on what pip is can be found here. In short is a convenient (and becoming a standard) way of installing python libraries.

if it continues to fail, it can be due to PIL searching those libraries in a different path.

It turns out that the APT installations put the libraries under /usr/lib/x86_64-linux-gnu and PIL will search for them in /usr/lib/. So you have to create symlinks for PIL to see them.

Try to see if libjpeg and libz libs exist in /usr/lib/x86_64-linux-gnu and make a symlink this way

The above solution did not work for me on Ubuntu 12.10 as libjpeg was not available in the repository.

What did end up working for me was:

If you get the error 'You must put some 'source' URIs in your sources.list' then make sure that your /etc/apt/sources.list has deb-src entries which match your deb entries.

Then you must symlink the files from their actual location on your server to the location where PIL expects them.

32-bit version

64-bit version

Finally, pip install PIL

Success!

Update Sep 2014

Pillow is a more modern fork of PIL.

I just want to add, that pip install pil no longer works, at least on my machine, you have to do

pip install PIL --allow-external PIL --allow-unverified PIL

The above answers create links for x64 libraries in x86 locations. Instead I would download the PIL source then add these lines in setup.py:

after these lines (~line 211)

reinstall PIL. If you're using pip:

Then from the source directory run:

This solution work for me on Ubuntu 14.04 as libjpeg was not available in the repository.

sudo apt-get install python-imaging now installs Pillow not PIL. As for selftest.py, you may need to check out the source to run it. And of course, you need to install the dependencies if you want PIL to support them e.g.

To run a version of PIL newer than is included in Ubuntu::

I needed to pip install Pillow in a virtualenv on 14.04 (not using system packages).

To build pillow from PyPI inside a virtualenv (Python 2.7):

.. then you can import PIL.

streamEye

streamEye is a simple MJPEG streamer for Linux. It acts as an HTTP server and is capable of serving multiple simultaneous clients.

It will feed the JPEGs read at input to all connected clients, in a MJPEG stream. The JPEG frames at input may be delimited by a given separator.In the absence of a separator, streamEye will autodetect all JPEG frames.

Installation

streamEye was tested on various Linux machines, but may work just fine on other platforms.Assuming your machine has git, gcc and make installed, just type the following commands to compile and install:

Usage

Usage: <jpeg stream> streameye [options]Available options:

• -d - debug mode, increased log verbosity
• -h - print this help text
• -l - listen only on localhost interface
• -p port - tcp port to listen on (defaults to 8080)
• -q - quiet mode, log only errors
• -s separator - a separator between jpeg frames received at input (will autodetect jpeg frame starts by default)
• -t timeout - client read timeout, in seconds (defaults to 10)

Examples

The following shell script will serve the JPEG files in the current directory, in a loop, with 2 frames per second:

The following command will stream your camera (assuming it's at /dev/video0), with 30 frames per second at 640x480:

Extras

raspimjpeg.py

This script continuously captures JPEGs from a Raspberry PI's CSI camera and writes them to standard output. It works out-of-the-box on Raspbian. The following command will make a simple MJPEG streamer out of your Raspberry PI:

Why not raspivid or raspistill? Well, at the time of writing raspivid doesn't output JPEGs and raspistill only works in stills mode.

Why Python and not C? Because most of the stuff is done by the GPU, so the insignificant performance gain would not make it worth writing C code. And of course because picamera is an amazing library.
