I think I'll withdraw this patch for now. Some stream group types have
several layers of data, so components and pieces would not be enough. This
is the case for IAMF Audio Elements and Mix Presentation, for example.
A generic way to add N amount of layers would be needed.
I see.
Does it mean that the nesting level is greater than 3 (side_data,
components, pieces)?
Yes. Look at AVIAMFMixPresentation, which has an array of AVIAMFSubmix,
which in turn have an array of AVIAMFSubmixLayout plus an array of
AVIAMFSubmixElement per submix, the latter which has a
AVIAMFParamDefinition per element.
If the AVIAMFMixPresentation is the component, the AVIAMFSubmix would be
the piece, and then we ran out of levels.
Probably the best we can do is some kind of flattening (ffprobe is not
designed for generic level of nesting, as we need to define the
structure of the layout, at least for some formats (e.g. XML)).
