sdp config data
---------------
The original data in the RTSP SDP

00 00 01 b0                                   // GST_MPEG4_VIDEO_OBJ_SEQ_START
03 
00 00 01 b5                                   // GST_MPEG4_VISUAL_OBJ
09 00 00 01 01 
00 00 01 20                                   // GST_MPEG4_VIDEO_LAYER_FIRST
00 86 e0 00 24 e2 20 03 e8 00 68 82 48 00
ce 18 b0 22 40 a3 1f 
00 00 01 b3                                   // GST_MPEG4_GROUP_OF_VOP
00 10 07

mpeg4 raw rtp
-------------
The config data is partially in the raw MPEG4 stream

00 00 01 20                                   // GST_MPEG4_VIDEO_LAYER_FIRST
00 86 e0 00 24 e2 20 03 e8 00 68 82 48 00
ce 18 b0 22 40 a3 1f 
00 00 01 b6                                   // GST_MPEG4_VIDEO_OBJ_PLANE

rtsp clean
----------
The configuration data is cleanly multiplexed with GStreamer when the
full RTSP is used

00 00 01 b0                                   // GST_MPEG4_VIDEO_OBJ_SEQ_START
03 
00 00 01 b5                                   // GST_MPEG4_VISUAL_OBJ
09 00 00 01 01
00 00 01 20                                   // GST_MPEG4_VIDEO_LAYER_FIRST
00 86 e0 00 24 e2 20 03 e8 00 68 82 48 00
ce 18 b0 22 40 a3 1f 
00 00 01 b0                                   // GST_MPEG4_VISUAL_OBJ_SEQ_START
03
00 00 01 b5                                   // GST_MPEG4_VISUAL_OBJ
09 00 00 01 01 
00 00 01 20                                   // GST_MPEG4_VIDEO_LAYER_FIRST
00 86 e0 00 24 e2 20 03 e8 00 68 82 48 00
ce 18 b0 22 40 a3 1f
00 00 01 b3                                   // GST_MPEG4_GROUP_OF_VOP
00 10 07 
00 00 01 b6                                   // GST_MPEG4_VIDEO_OBJ_PLANE

caps with rtsp
--------------
When looking at the caps of the mpeg4 parser with the full RTSP session

00 00 01 b0                                   // GST_MPEG4_VIDEO_OBJ_SEQ_START
03 
00 00 01 b5                                   // GST_MPEG4_VISUAL_OBJ
09 00 00 01 01
00 00 01 20                                   // GST_MPEG4_VIDEO_LAYER_FIRST
00 86 e0 00 24 e2 20 03 e8 00 68 82 48 00 
ce 18 b0 22 40 a3 1f
00 00 01 b3                                   // GST_MPEG4_GROUP_OF_VOP
