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)). > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe". _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
