When you copy a stream as-is, copying each byte individually or grouping
them by 3 doesn't matter. The "copy" codec simply pass the bytes making up
the stream without interpretation. Since all streams are made of bytes (at
least when put in a file), -c copy -f u8 will always work, whatever the
actual stream might be.
This is just about the copy codec; why the remainder fail I have no idea.
