[gst-devel] a GstType for a musical note

[Stefan Kost]

hi hi,

in gstreamer/gst/gstvalue.{c,h} we define custom g_value_types for e.g. 
GST_TYPE_FOURCC, GST_TYPE_INT_RANGE, GST_TYPE_DOUBLE_RANGE, GST_TYPE_LIST, 
GST_TYPE_FIXED_LIST, GST_TYPE_FRACTION

For audio-synth plugins instead of a frequency one usually supplies a keyboard 
note, either as a number or in a 3 char notation (C-0, D#5).
I'd prefer to have GValue Type for it, rather that using a normal integer or a 
direct frequency.

Again the question is where to put it. There core does not really need to know 
about it (besides gst-inspect showing the proper param type of an elemnt).
Having this in plugins would be good, so that multiple plugins can use the same 
type and apps can rely on the type.

Any ideas, comments.

Stefan
