# VLog Transcoding Worker Service Template
# Copy to /etc/systemd/system/vlog-worker.service and customize:
#   - Replace <YOUR_USER> with your username
#   - Replace /path/to/vlog with your installation path
#   - Adjust storage path if not using /mnt/nas/vlog-storage
#   - Adjust MemoryMax based on your system (8G recommended for transcoding)
