Kurtnoise13,
I tried to create MP4 with HEAAC. As it mentioned it a ISO_IEC_14496-3_2001_Amd_1_2003_PDF_version_(en)_038148_CPDF.pdf ,
The High Efficiency AAC Profile contains the audio object types 5 (SBR) and 2(AAC LC). So first 5 bits in AudioSpecificConfig should te 5 for HEAAC for right handling of extensions (ext ObjType, ext Freq & Freq Index). And BeLight writes 2 to this field.
