The PNG specification is irrelevant.
The libavcodec decoder decodes to PIX_FMT_RGB32 which means each pixel
is a 32 bit value in native endianness with the (I think) highest bits
being red, followed by green and blue.
Since the code works byte-wise, it is correct to do different things on
big- and little-endian.
