+Streaming video compositor for real-time effect processing.
+
+This module provides a frame-by-frame streaming architecture that:
+- Reads from multiple video sources with automatic looping
+- Applies effects inline (no intermediate files)
+- Composites layers with time-varying weights
+- Outputs to display, file, or stream
+
+Usage:
+    from streaming import StreamingCompositor, VideoSource, AudioAnalyzer
+
+    compositor = StreamingCompositor(
+        sources=["video1.mp4", "video2.mp4"],
+        effects_per_source=[...],
+        compositor_config={...},
+    )
+
+    # With live audio
+    audio = AudioAnalyzer(device=0)
+    compositor.run(output="output.mp4", duration=60, audio=audio)
+
+    # With preview window
+    compositor.run(output="preview", duration=60)
+
+Backends:
+    - numpy: Works everywhere, ~3-5 fps (default)
+    - glsl: Requires GPU, 30+ fps real-time (future)
