What does the 16 bytes "00 00 04 00 ... 02" after the SampleRate mean???

Probably, that 16 bytes data is old QuickTime format.
I think when the version of stsd is 0 and the entry_version of AudioSampleEntry is 1, the format would be used.

380578 = 0x5cea2
380578 + 18 = 380596 = 0x5ceb4

Hexdump

The ColourType of this colr box is "nclc".
But go-mp4 supports only "nclx", "rICC" and "prof".
So I think that go-mp4 should accept any ColourType using byte array.
