Q: Assuming we have formatted streams, does the format include encodings?
For example: 'LtRt' is a 4-channel encoding, stored on 2-channels.
a) Yes. Plugins that care can accept or deny those encodings.
- downside is that you can corrupt the encoded stream with a plugin
which doesn't care
b) No. Encodings are decoded while inside the GMPI graph.
- downside is that you can do encoding-incompatible things to decoded
streams
c) Other. Explain?
