MovieExportFromProceduresToDataRef is *almost* exactly what I need to
generate movies from raw sample data.
BUT...
I need this functionality in a situation where the export process is
driven by the availability of data samples. Unfortunately the
opposite is the case with MovieExportFromProceduresToDataRef where
the assumption is that sample data is immediately available for the
video and audio data source callbacks.
So...
a) Is there an alternative to using
MovieExportFromProceduresToDataRef (lower level APIs?) that achieves
the same function, but can be driven by data availability?
b) Is it somehow possible to return a 'not ready yet, please call
back later' flag in the data source callbacks?
c) Is it possible to buffer a set of audio and video samples, call
MovieExportFromProceduresToDataRef to do its thing and empty the
sample buffers, and then repeat this process appending to the same
DataRef (movie) each time?
I notice a few others have asked questions along similar lines.
