phoglund@webrtc.org 8400246fce Improved error messages when binaries are missing. Also stderr = stdout now.

Now that these scripts are called from browser tests, we need to print everything on stdout since the tests will throw away stderr when invoking programs. I chose to assign sys.stderr to sys.stdout. Otherwise I would have missed stuff like parser.error, which print to stderr.

The error message will get improved because the old code did not catch the case when the binary was missing, which lead to a very confusing error when that was the case. This gets fixed now.

README

This file explains how to get the dependencies needed for the barcode tools.

barcode_encoder.py
==================
This script depends on:
* Zxing (Java version)
* Ant (must be installed manually)
* Java

To automatically download Zxing for the encoder script, checkout this directory
as a separate gclient solution, like this:
gclient config http://webrtc.googlecode.com/svn/trunk/webrtc/tools/barcode_tools
gclient sync
Then the Zxing Java source code will be put in third_party/zxing.

In order to run barcode_encoder.py you then need to build:
* zxing/core/core.jar
* zxing/javase/javase.jar
These are compiled using Ant by running build_zxing.py:
python build_zxing.py

For more info about Zxing, see https://code.google.com/p/zxing/


barcode_decoder.py
==================
This script depends on:
* Zxing (C++ version). You need to checkout from Subversion and build the libs
  and zxing SCons targets. SVN URL: http://zxing.googlecode.com/svn/trunk/cpp
* FFMPEG fmpeg 0.11.1

These dependencies must be precompiled separately before running the script.
Make sure to add FFMPEG to the PATH environment variable and provide the path
to the zxing executable using the mandatory command line flag to the script.
