Comment:
The extradata (CodecPrivate in Matroska parlance) of HEVC in Matroska is
supposed to contain a HEVCDecoderConfigurationRecord and there is
currently only one legal version of HEVCDecoderConfigurationRecord, namely
version 1. Yet your file claims to be of version 0 (as the first byte of
the CodecPrivate indicates). Simply remuxing this would lead to an invalid
file (because version 0 is not valid).
If one changes the byte 0x00 at offset 4329 in your file by 0x01, remuxing
succeeds (and the file seems fine).
