Configure FFmpeg Transcoding Service
By default, when FFmpeg is installed, multiple renditions are configured (transcodings) as per the DAM Update Asset workflow definition.
As the transcodings are CPU intensive, it is recommended to modify the list of target renditions. In most cases, transcoding is not necessary.
To modify the DAM Update Asset workflow, and in this example, to turn off transcoding:
-
Sign into the author instance with administrative privileges.
-
From global navigation, navigate to Tools > Workflow > Models.
-
Locate DAM Update Asset.
-
Double-click to open the workflow for edit in the Classic UI.
Resulting location: http://localhost:4502/cf#/etc/workflow/models/dam/update_asset.html
-
Double-click the FFmpeg transcoding step to access the Step Properties dialog.
-
Under the Process tab:
- Arugments: Clear all entries to disable transcoding Default values:
profile:format_ogg,profile:format_aac,profile:format_flv,profile:format_aac_ie
- Arugments: Clear all entries to disable transcoding Default values:
-
Select OK to close the
Step Propertiesdialog. -
Select Save to save the
