16 FATE is an extended regression suite on the client-side and a means
17 for results aggregation and presentation on the server-side.
19 The first part of this document explains how you can use FATE from
20 your FFmpeg source directory to test your ffmpeg binary. The second
21 part describes how you can run FATE to submit the results to FFmpeg's
24 In any way you can have a look at the publicly viewable FATE results
25 by visiting this website:
27 @url{http://fate.ffmpeg.org/}
29 This is especially recommended for all people contributing source
30 code to FFmpeg, as it can be seen if some test on some platform broke
31 with their recent contribution. This usually happens on the platforms
32 the developers could not test on.
34 The second part of this document describes how you can run FATE to
35 submit your results to FFmpeg's FATE server. If you want to submit your
36 results be sure to check that your combination of CPU, OS and compiler
37 is not already listed on the above mentioned website.
39 In the third part you can find a comprehensive listing of FATE makefile
40 targets and variables.
43 @chapter Using FATE from your FFmpeg source directory
45 If you want to run FATE on your machine you need to have the samples
46 in place. You can get the samples via the build target fate-rsync.
47 Use this command from the top-level source directory:
50 make fate-rsync SAMPLES=fate-suite/
51 make fate SAMPLES=fate-suite/
54 The above commands set the samples location by passing a makefile
55 variable via command line. It is also possible to set the samples
56 location at source configuration time by invoking configure with
57 @option{--samples=<path to the samples directory>}. Afterwards you can
58 invoke the makefile targets without setting the @var{SAMPLES} makefile
59 variable. This is illustrated by the following commands:
62 ./configure --samples=fate-suite/
67 Yet another way to tell FATE about the location of the sample
68 directory is by making sure the environment variable FATE_SAMPLES
69 contains the path to your samples directory. This can be achieved
70 by e.g. putting that variable in your shell profile or by setting
71 it in your interactive session.
74 FATE_SAMPLES=fate-suite/ make fate
78 Do not put a '~' character in the samples path to indicate a home
79 directory. Because of shell nuances, this will cause FATE to fail.
82 To use a custom wrapper to run the test, pass @option{--target-exec} to
83 @command{configure} or set the @var{TARGET_EXEC} Make variable.
86 @chapter Submitting the results to the FFmpeg result aggregation server
88 To submit your results to the server you should run fate through the
89 shell script @file{tests/fate.sh} from the FFmpeg sources. This script needs
90 to be invoked with a configuration file as its first argument.
93 tests/fate.sh /path/to/fate_config
96 A configuration file template with comments describing the individual
97 configuration variables can be found at @file{doc/fate_config.sh.template}.
100 The mentioned configuration template is also available here:
101 @verbatiminclude fate_config.sh.template
104 Create a configuration that suits your needs, based on the configuration
105 template. The @env{slot} configuration variable can be any string that is not
106 yet used, but it is suggested that you name it adhering to the following
107 pattern @samp{@var{arch}-@var{os}-@var{compiler}-@var{compiler version}}. The
108 configuration file itself will be sourced in a shell script, therefore all
109 shell features may be used. This enables you to setup the environment as you
110 need it for your build.
112 For your first test runs the @env{fate_recv} variable should be empty or
113 commented out. This will run everything as normal except that it will omit
114 the submission of the results to the server. The following files should be
115 present in $workdir as specified in the configuration file:
125 When you have everything working properly you can create an SSH key pair
126 and send the public key to the FATE server administrator who can be contacted
127 at the email address @email{fate-admin@@ffmpeg.org}.
129 Configure your SSH client to use public key authentication with that key
130 when connecting to the FATE server. Also do not forget to check the identity
131 of the server and to accept its host key. This can usually be achieved by
132 running your SSH client manually and killing it after you accepted the key.
133 The FATE server's fingerprint is:
137 d3:f1:83:97:a4:75:2b:a6:fb:d6:e8:aa:81:93:97:51
139 76:9f:68:32:04:1e:d5:d4:ec:47:3f:dc:fc:18:17:86
142 If you have problems connecting to the FATE server, it may help to try out
143 the @command{ssh} command with one or more @option{-v} options. You should
144 get detailed output concerning your SSH configuration and the authentication
147 The only thing left is to automate the execution of the fate.sh script and
148 the synchronisation of the samples directory.
150 @chapter Uploading new samples to the fate suite
152 If you need a sample uploaded send a mail to samples-request.
154 This is for developers who have an account on the fate suite server.
155 If you upload new samples, please make sure they are as small as possible,
156 space on each client, network bandwidth and so on benefit from smaller test cases.
157 Also keep in mind older checkouts use existing sample files, that means in
158 practice generally do not replace, remove or overwrite files as it likely would
159 break older checkouts or releases.
160 Also all needed samples for a commit should be uploaded, ideally 24
161 hours, before the push.
162 If you need an account for frequently uploading samples or you wish to help
163 others by doing that send a mail to ffmpeg-devel.
166 #First update your local samples copy:
167 rsync -vauL --chmod=Dg+s,Duo+x,ug+rw,o+r,o-w,+X fate-suite.ffmpeg.org:/home/samples/fate-suite/ ~/fate-suite
169 #Then do a dry run checking what would be uploaded:
170 rsync -vanL --no-g --chmod=Dg+s,Duo+x,ug+rw,o+r,o-w,+X ~/fate-suite/ fate-suite.ffmpeg.org:/home/samples/fate-suite
173 rsync -vaL --no-g --chmod=Dg+s,Duo+x,ug+rw,o+r,o-w,+X ~/fate-suite/ fate-suite.ffmpeg.org:/home/samples/fate-suite
177 @chapter FATE makefile targets and variables
179 @section Makefile targets
183 Download/synchronize sample files to the configured samples directory.
186 Will list all fate/regression test targets.
189 Run the FATE test suite (requires the fate-suite dataset).
192 @section Makefile variables
196 Verbosity level, can be set to 0, 1 or 2.
198 @item 0: show just the test arguments
199 @item 1: show just the command used in the test
200 @item 2: show everything
204 Specify or override the path to the FATE samples at make time, it has a
205 meaning only while running the regression tests.
208 Specify how many threads to use while running regression tests, it is
209 quite useful to detect thread-related regressions.
212 Specify which threading strategy test, either @samp{slice} or @samp{frame},
213 by default @samp{slice+frame}
219 Specify or override the wrapper used to run the tests.
220 The @env{TARGET_EXEC} option provides a way to run FATE wrapped in
221 @command{valgrind}, @command{qemu-user} or @command{wine} or on remote targets
222 through @command{ssh}.
225 Set to @samp{1} to generate the missing or mismatched references.
228 Specify which hardware acceleration to use while running regression tests,
229 by default @samp{none} is used.
232 Set to @samp{1} to keep temp files generated by fate test(s) when test is successful.
233 Default is @samp{0}, which removes these files. Files are always kept when a test
