| 32 | the command-line interface (<command>ffmpeg</command>) tries to figure out

|
|---|
| 278 | url="https://www.ffmpeg.org/fate.html"> FFmpeg Automated Testing
|
|---|
| 279 | Environment</ulink> (FATE). First, about 1 GB of sample files used to
|
|---|
| 280 | run FATE are downloaded with the command:
|
|---|
| 281 | </para>
|
|---|
| 282 |

|

|

| 285 | <para>
|
|---|
| 286 | The <filename class="directory">fate-suite</filename> directory is
|
|---|
| 287 | created and the files are downloaded there. That command actually runs an
|
|---|
| 288 | rsync command to obtain the sample files. You may want to compress and
|
|---|
| 289 | keep this directory for testing again, for testing in another system,
|
|---|
| 290 | or for when a new version of ffmpeg is released. Then, unpack the sample
|
|---|
| 291 | files in the source directory, and run the <command>make fate-rsync
|
|---|
| 292 | ...</command> command above to sync with the upstream repository. The
|
|---|
| 293 | download size and time are drastically reduced by doing this. Estimated
|
|---|
| 294 | values in "Package Information" do not include the download SBU. Some
|
|---|
| 295 | samples may have been removed in newer versions, so in order to be sure
|
|---|
| 296 | local and server fate samples are identical when you use previously
