What does video transcoding actually do?

I'm re-encoding all videos in my immich library, after clearing all assets.encodedVideoPath values in the db and deleting the encoded-video dir. A few questions:

  1. The job queue shows ~187k jobs waiting but I only have 8k videos on my server. Is immich adding all assets (including photos) to the transcode queue?
  2. immich-microservices logs contain many entries like this:
[MediaService] Start encoding video 5c800eac-fcd3-43be-aca0-28d2e04e5617 { ... }
[MediaService] Encoding success 8a78614d-d8b7-4612-aec7-73a1729f2786
[MediaService] Start encoding video 0a51047e-ceff-4f78-8e39-cef5ab75e821 { ... }
[MediaService] Encoding success 6cfd60cc-44af-47dd-8883-c9cbf4030dab


but the "start encoding" and "encoding success" IDs never seem to match one another. Is this expected?

  1. The number of files in $IMMICH_DATA/encoded-video grows very slowly, much slower than the "encoding success" logs. At the same time, my CPU is essentially saturated by transcoding, with apparently no output to show for it. What could explain this? Also check the attached screenshot, it shows available storage over the past 24h during continuous transcoding. It has become pretty much flat for the past few hours.
