I do not have ffmpeg installed on my machine, but wdio-mediawiki tries to use it anyway for recording a video, and fails with:
[Chrome 131.0.0.0 linux #0-0] spawn ffmpeg ENOENT [Chrome 131.0.0.0 linux #0-0] Error: spawn ffmpeg ENOENT [Chrome 131.0.0.0 linux #0-0] at ChildProcess._handle.onexit (node:internal/child_process:284:19) [Chrome 131.0.0.0 linux #0-0] at onErrorNT (node:internal/child_process:477:16) [Chrome 131.0.0.0 linux #0-0] at process.processTicksAndRejections (node:internal/process/task_queues:82:21)
The code should probably just do nothing when ffmpeg is not available.
