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).
