vsp-tests
---------

Test suite for the Renesas R-Car VSP1 and VSP2 video processing engines.

You can find the latest version of vsp-tests in the project's git tree at

	git://git.ideasonboard.com/renesas/vsp-tests.git
	http://git.ideasonboard.com/renesas/vsp-tests.git


--------
Building
--------

The vsp-tests suite requires the following tools to be installed on the host
to generate the test scripts, applications and data.

* gcc
* make
* python

After installing the needed packages, you can build the test suite by running

	make

in the vsp-tests root directory. Then, to install the test suite, run

	make install INSTALL_DIR=/path/to/target/directory

This will copy the test scripts and applications to the target directory to be
copied or exported to the host.


--------------------
Runtime Dependencies
--------------------

The tests scripts require the following tools to be installed on the target
system in a directory included in $PATH.

* compare (part of ImageMagick)
* media-ctl (part of v4l-utils, available at git://linuxtv.org/v4l-utils.git)
* raw2rgbpnm (available at git://git.retiisi.org.uk/~sailus/raw2rgbpnm.git)
* yavta (available at git://git.ideasonboard.org/yavta.git)

All but the HGO and CLU/LUT tests can be run with the latest version of these
tools. To test the HGO and CLU/LUT, the 'vsp' branch of 'yavta' is currently
needed.


-----------------
Running the Tests
-----------------

The test scripts are named vsp-unit-test-[0-9]*.sh. They can be run directly
from the test suite root directory.

Test options:

- VSP_KEEP_FRAMES: When the VSP_KEEP_FRAMES environment variable is set to 1,
  all frame files will be preserved regardless of the tests results. Otherwise
  frame files for successful tests are removed.
