Render feature #1990
Description
Right now we have a basic libav exporter feature in the libav device.
We should
- Enable export mode for all the plug-in APIs that require it e.g. VST etc.
- Support frame-accurate export
- Ensure absolutely no part of the codebase uses "current time"
- Think of a way to save automation, etc. data (maybe could go in some MPEG container metadata?)
- Define what happens for interactive input. Do we want real-time recording or off-line export at maximum speed?
- Verify that we can do 1-sample render
