FFmpeg is a solution for converting and streaming audio and video and, when installed, is used for proper transcoding of video assets as well as for AEM Communities’ enablement feature.
FFmpeg is used in the author environment to obtain metadata for uploaded enablement resources as well as generate a thumbnail to display when listing the enablement resource.
FFmpeg should be installed on the server(s) hosting the AEM author instance(s).
Go to https://www.ffmpeg.org
Download the latest version of FFmpeg for your specific environment (Macintosh, Windows, or Linux)
Install FFmpeg following instructions for the OS.
Make sure the FFmpeg executable is set in your system path.
You should be able to run FFmpeg from any directory in your system.
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: 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:
Select OK to close the
Step Properties dialog
Select Save to save the
