Fix concurrent ffmpeg segment racing

2026-08-04T16:33:42Z

This is a nasty one. The failure mode is: 1. Request A started FFmpeg and waited for a segment. 2. Request B requested an earlier or far away segment. 3. Jellyfin thought FFmpeg should to restart at a different position. 4. Request B killed the existing transcoding job. 5. Killing that job cancelled the same token request A was using. 6. The cancellation produced http 500 to request A. To fix this: we lock transcoding job state changes and segment handling per playlist, and use a thread safe counter to track how many http responses are still using each job’s segments. A job is only stopped or replaced once that counter reaches zero.

Drain stderr and stdout concurrently for encoder validation

Some ffmpeg build might output extremely long traces for its banner that consume all pipe capacity and hangs the process. We have to drain both streams regardless on which one we actually read.
