MEDIA PROCESSING
- Video operators can also be integrated as Tcl video objects:
- usually inserted between video sources and players,
- allow structured multi-source audio and video processing.
- signal flow graphs are easily described in iTcl.
- For audio processing the model is similar.
- sample packets circulate between audio processing nodes:
- mixers, fft filters and resamplers...
- monitoring metaphors can also be inserted (signal/spectrum probes).
- Operations need an explicit ``activate'' method invocation.
