action #77845

Updated by okurz 5 months ago

## Motivation 
 See #68923 

 ## Acceptance criteria 

 * **AC1:** All osd workers run the same external video encoder configured (exceptions allowed if required and documented) as in #77839 
 * **AC2:** All osd workers are not overstressed by the external video encoder, i.e. not more jobs failing or incompleting due to an overstressed worker 

 ## Suggestions 

 * Research what has been done in #77839 and #77842 
 * Ensure ffmpeg is installed on all worker machines with salt 
 * Configure external video encoder as documented in #68923#note-17 but with salt 
 * Do a step-wise roll-out, e.g. based on salt roles 
 * Monitor the CPU usage of ffmpeg e.g. via `htop` and also the overall performance of each worker, e.g. check for incomplete jobs due to performance issues 
 * Wait for feedback for some days
