export DISPLAY=':0.0'
# Synthesizer parameter description
Example of invoking the synthesizer from the command line:
./processServer \
-taskFilePath %s \
-taskId %s \
-outputFilePath %s \
-patternPath /var/www/html/bsedit/material/ \
-serverURL http://localhost:8088/ \
-licServerURL https://eapi.meishesdk.com:7443/app \
-faceModelFilePath /opt/bsedit/ms_face_v1.0.2.model
The parameter description is as follows:
| Parameters | Description |
|---|---|
| taskFilePath | The local path of the project file |
| inputM3u8FilePath | The local path of the m3u8 file (choose one from the project file) |
| taskId | task ID |
