Created an attachment (id=141654)
patch to set offset and offset_end on the header buffer

schroenc element doesn't set OFFSET and OFFSET_END correctly on the
streamheader buffers. That causes a problem if there's a multifdsink with a
pair of gdppay + gdpdepay between the schroenc and oggmux - oggmuxer will just
keep buffering output page buffers.

The following pipeline illustrates the problem; the fakesink will only receive
a single data buffer, while it should receive more.

gst-launch-0.10 -v videotestsrc ! schroenc ! gdppay ! tcpserversink port=13524
recover-policy=1 & sleep 1; gst-launch-0.10 -v tcpclientsrc port=13524 !
gdpdepay ! oggmux ! fakesink

Attaching a patch to set the dirac header buffer's OFFSET and OFFSET_END
according to the expectations of the oggmux.
