 changelog:
-  - Add diagnostic logging for Trailer Pre-Roll and Feature Pre-Roll bumpers —
-    logs a warning if the configured library ID is invalid, and a debug message
-    when no eligible movie is found or which movie was picked, to help
-    troubleshoot why a bumper isn't playing
+  - yt-dlp now prefers H.264 + AAC (plays or hardware-transcodes on every
+    client; VP9/AV1 often needed a CPU transcode) and uses Jellyfin's own
+    ffmpeg for the merge
+  - If yt-dlp fails, the built-in downloader is tried instead
+  - Fix a possible hang. yt-dlp's output is now read while it runs, so a
+    full output buffer can no longer block it
