FFMpeg times out, automation never finishes #549
Description
Checklist

- I have filled out the issue template to the best of my ability.

- This is a bug and not a feature request.
- I have searched open issues for my problem.
Describe the issue
Periodically (I haven't been able to reproduce this deterministically), ffmpeg times out and my automation never finishes. Since this automation was set to 'queued', this jams up the queue and the automation does not run until I disable and re-enable the trigger.
I know any potential bugs in ffmpeg are out of scope here, but ffmpeg's failure should not hang my automation's queue.
Reproduction steps
Unfortunately, I haven't been able to reproduce this with deterministic steps, but it seems to happen at least every couple of days. It doesn't seem to matter how many times the automation actually runs prior to the failure.
LLMVision is running against videos from my Blink doorbell camera. These videos are at most 1 minute long and have never been more than 5 megabytes. When it succeeds (which is most of the time), the entire LLMVision operation (including the AI query) completes in 2 or 3 seconds.
