Can someone tell me what byte order (i.e. little endian or big endian)
used in file meta sink (i.e. what is the byte order of the resulting
file)? I’m seeing something strange, and I’m wondering if the header
(metadata portion) is big endian while the samples are little endian.
this change based on the endianness of the host machine?
the metadata is stuffed into PMT dicts, which get serialized by pmt’s
Now, these are a bit peculiar on serializing multibyte things. They
generally ensure big-endianness, if I understand the code  correctly.
The sample portion would have the same endianness as your host
architecture, so that would explain differences.
