Alternative IPC Example - File/Redis IPC Client for Physiology Server
This example demonstrates using alternative IPC stream backends (File or Redis) instead
of gRPC streams for communication with the physiology server.
Supported stream backends:
- File: Server writes data to files, client reads from filesystem
- Redis: Server publishes to Redis, client subscribes to Redis channels
Key differences from the gRPC streaming example:
- No frame sending (server gets frames from webcam directly)
- Reads metrics from alternative IPC stream backend instead of gRPC streams
- Reads frames from the alternative stream backend for display
- Only uses gRPC for control commands and logs
