Comprehensive Logging System + +**Log Files (in log_dir):** +- `tv_movies.jsonl` - Successful encodes from /tv and /movies +- `content.jsonl` - Successful encodes from /content +- `failed_encodes.jsonl` - Encoding errors +- `failed_searches.jsonl` - Files that couldn't hit any VMAF target +- `low_savings_skips.jsonl` - Files with <12% savings + 15% estimates + +**Log Entry Structure:** +```json +{ + "file": "/path/to/file.mkv", + "status": "success", + "vmaf": 94.0, + "crf": 37.0, + "before": { + "codec": "h264", + "width": 1280, + "height": 720, + "bitrate": 1010, + "size": 158176376, + "duration": 1252.298 + }, + "after": { + "codec": "av1", + "width": 1280, + "height": 720, + "bitrate": 775, + "size": 121418115, + "duration": 1252.296 + }, + "duration": 1299.28, + "savings": 23.24, + "timestamp": "2025-12-31T13:56:55.894288" +} +``` + +### 3.

Plex Refresh on Completion + +**Configuration:** +```bash +python3 optimize_library.py /media \ + --plex-url http://localhost:32400 \ + --plex-token YOUR_TOKEN_HERE +``` + +**Behavior:** +- After all files processed (or shutdown), triggers Plex library refresh +- Only refreshes if at least 1 file was successfully encoded +- Uses Plex API: `GET /library/sections/1/refresh` + +**To get Plex token:** +1. Sign in to Plex Web +2. Go to Settings → Network +3. Look for "List of IP addresses and ports that have authorized devices" +4. Copy token (long alphanumeric string) + +### 7.
