For RTP use, you should not have deal with any endianness issue. The
encoder takes in PCM values as floats or 16-bit ints in the native
endianness of your DSP. The output packet is a stream of bytes, so it
has no endianness issue. The only endianness issue you may need to be
aware of is if you use the opus_demo test program, which inputs and
outputs audio as little endian.
