| 263 | installed and follow the instructions for the <ulink
|
|---|
| 264 | url="http://www.ffmpeg.org/fate.html"> FFmpeg Automated Testing
|
|---|
| 265 | Environment</ulink> (FATE). First, about 927 MB of sample files used to
|
|---|
| 266 | run FATE are downloaded with the command:
|
|---|
| 267 | </para>
|
|---|
| 268 |
|

| 269 | <screen><userinput>make fate-rsync SAMPLES=fate-suite/</userinput></screen>
|

|
|---|
| 271 | <para>
|
|---|
| 272 | The <filename class="directory">fate-suite</filename> directory is
|
|---|
| 273 | created and the files are downloaded there. That command actually runs an
|
|---|
| 274 | rsync command, to obtain the sample files. You may want to compress and
|
|---|
| 275 | keep this directory for testing again, in another system, or when a new
|
|---|
| 276 | version of ffmpeg is launched. Then, you unpack the sample files in the
|
|---|
| 277 | source directory, and run, again, the <command>make fate-rsync
|
|---|
| 278 | ...</command> command above, to sync with the repository. Now, the
|
|---|
| 279 | download size and time are drastically reduced. Estimated values in
|
|---|
| 280 | "Package Information" do not include the download SBU. Some samples may
|
|---|
| 281 | have been removed, in the new version, so, in order to be sure local and
|
|---|
| 282 | server fate samples are identical, when you use previously saved samples,
|
|---|
| 283 | run the following command:
|
|---|
