Segment is not just about seeking. Segment event is mandatory since
GStreamer 1.2. As your plugin receive data from libsoup, it should
simply forward the received segment (sent by souphttpsrc), which is
expected to be in bytes format. Though, if the segment is bounded, and
your element changes the buffer size, you'll have to do more work to
correctly translate the seeks if you want to support that (probably not,
from the comment).
