@chapter Introduction
|
|
|
|
FATE is an extended regression suite on the client-side and a means
|
|
for results aggregation and presentation on the server-side.
|
|
|
|
The first part of this document explains how you can use FATE from
|
|
your FFmpeg source directory to test your ffmpeg binary. The second
|
|
part describes how you can run FATE to submit the results to FFmpeg's
|
|
FATE server.
|
|
|
|
In any way you can have a look at the publicly viewable FATE results
|
|
by visiting this website:
|
|
|
|
@url{http://fate.ffmpeg.org/}
|
|
|
|
This is especially recommended for all people contributing source
|
|
code to FFmpeg, as it can be seen if some test on some platform broke
|
|
with their recent contribution. This usually happens on the platforms
|
|
the developers could not test on.
|
|
|
|
The second part of this document describes how you can run FATE to
|
|
submit your results to FFmpeg's FATE server. If you want to submit your
|
|
results be sure to check that your combination of CPU, OS and compiler
|
|
is not already listed on the above mentioned website.
|
|
|
|
In the third part you can find a comprehensive listing of FATE makefile
|
|
targets and variables.
|
|
|
|
|
|
@chapter Using FATE from your FFmpeg source directory
|
|
|
|
If you want to run FATE on your machine you need to have the samples
|
|
in place. You can get the samples via the build target fate-rsync.
|
|
Use this command from the top-level source directory:
|
|
|
|
@example
|
|
make fate-rsync SAMPLES=fate-suite/
|
|
make fate SAMPLES=fate-suite/
|
|
@end example
|
|
|
|
The above commands set the samples location by passing a makefile
|
|
variable via command line. It is also possible to set the samples
|
|
location at source configuration time by invoking configure with
|
|
`--samples=<path to the samples directory>'. Afterwards you can
|
|
invoke the makefile targets without setting the SAMPLES makefile
|
|
variable. This is illustrated by the following commands:
|
|
|
|
@example
|
|
./configure --samples=fate-suite/
|
|
make fate-rsync
|
|
make fate
|
|
@end example
|
|
|
|
Yet another way to tell FATE about the location of the sample
|
|
directory is by making sure the environment variable FATE_SAMPLES
|
|
contains the path to your samples directory. This can be achieved
|
|
by e.g. putting that variable in your shell profile or by setting
|
|
it in your interactive session.
|
|
|
|
@example
|
|
FATE_SAMPLES=fate-suite/ make fate
|
|
@end example
|
|
|
|
@float NOTE
|
|
Do not put a '~' character in the samples path to indicate a home
|
|
directory. Because of shell nuances, this will cause FATE to fail.
|
|
@end float
|
|
|
|
To use a custom wrapper to run the test, pass @option{--target-exec} to
|
|
@command{configure} or set the @var{TARGET_EXEC} Make variable.
|
|
|
|
|
|
@chapter Submitting the results to the FFmpeg result aggregation server
|
|
|
|
To submit your results to the server you should run fate through the
|
|
shell script @file{tests/fate.sh} from the FFmpeg sources. This script needs
|
|
to be invoked with a configuration file as its first argument.
|
|
|
|
@example
|
|
tests/fate.sh /path/to/fate_config
|
|
@end example
|
|
|
|
A configuration file template with comments describing the individual
|
|
configuration variables can be found at @file{doc/fate_config.sh.template}.
|
|
|
|
@ifhtml
|
|
The mentioned configuration template is also available here:
|
|
@verbatiminclude fate_config.sh.template
|
|
@end ifhtml
|
|
|
|
Create a configuration that suits your needs, based on the configuration
|
|
template. The `slot' configuration variable can be any string that is not
|
|
yet used, but it is suggested that you name it adhering to the following
|
|
pattern <arch>-<os>-<compiler>-<compiler version>. The configuration file
|
|
itself will be sourced in a shell script, therefore all shell features may
|
|
be used. This enables you to setup the environment as you need it for your
|
|
build.
|
|
|
|
For your first test runs the `fate_recv' variable should be empty or
|
|
commented out. This will run everything as normal except that it will omit
|
|
the submission of the results to the server. The following files should be
|
|
present in $workdir as specified in the configuration file:
|
|
|
|
@itemize
|
|
@item configure.log
|
|
@item compile.log
|
|
@item test.log
|
|
@item report
|
|
@item version
|
|
@end itemize
|
|
|
|
When you have everything working properly you can create an SSH key pair
|
|
and send the public key to the FATE server administrator who can be contacted
|
|
at the email address @email{fate-admin@@ffmpeg.org}.
|
|
|
|
Configure your SSH client to use public key authentication with that key
|
|
when connecting to the FATE server. Also do not forget to check the identity
|
|
of the server and to accept its host key. This can usually be achieved by
|
|
running your SSH client manually and killing it after you accepted the key.
|
|
The FATE server's fingerprint is:
|
|
|
|
@table @option
|
|
@item RSA
|
|
d3:f1:83:97:a4:75:2b:a6:fb:d6:e8:aa:81:93:97:51
|
|
@item ECDSA
|
|
76:9f:68:32:04:1e:d5:d4:ec:47:3f:dc:fc:18:17:86
|
|
@end table
|
|
|
|
If you have problems connecting to the FATE server, it may help to try out
|
|
the @command{ssh} command with one or more @option{-v} options. You should
|
|
get detailed output concerning your SSH configuration and the authentication
|
|
process.
|
|
|
|
The only thing left is to automate the execution of the fate.sh script and
|
|
the synchronisation of the samples directory.

|
|
meaning only while running the regression tests.
|
|
|
|
@item THREADS
|
|
Specify how many threads to use while running regression tests, it is
|
|
quite useful to detect thread-related regressions.
|
|
|
|
@item THREAD_TYPE

|
|
by default @var{slice+frame}

|
|
|
|
@item TARGET_EXEC

|
|
The @var{TARGET_EXEC} option provides a way to run FATE wrapped in
|
|
@command{valgrind}, @command{qemu-user} or @command{wine} or on remote targets
|
|
through @command{ssh}.
|
|
|
|
@item GEN
