ext/xvid/gstxvidenc.c: Patch to mark outgoing encoded buffers as delta-units (or not).

Browse source 
Original commit message from CVS:
Patch by: Mark Nauwelaerts <manauw at skynet dot be>
* ext/xvid/gstxvidenc.c: (gst_xvidenc_init), (gst_xvidenc_setup),
(gst_xvidenc_chain):
Patch to mark outgoing encoded buffers as delta-units (or not).
Note that this patch also patches:
- the setting of fincr and fbase in xvid-encoder creation based on
caps framerate
- makes 0, rather than 2, the default max_b_frames, as the current
xvidenc does not seem "fully prepared" to handle b-frame
"effects", such as encoder returning 0 encoded bytes, etc.
Fixes #335585
