Original commit message from CVS: * gst-libs/gst/rtp/gstbasertpdepayload.c: (gst_base_rtp_depayload_chain): Validate the RTP packet before further processing it. It's just too dangerous to accept random packets and people are not forced to use a jitterbuffer or session manager to filter out the bad packets. * gst-libs/gst/rtp/gstrtpbuffer.c: (gst_rtp_buffer_set_extension_data), (gst_rtp_buffer_get_payload_subbuffer): Small cleanups. When setting extension data in a buffer that is too small, we fail and we should not set the extension bit. Change GST_WARNINGS into g_warning because they really are programming errors. * tests/check/libs/rtp.c: (GST_START_TEST): Catch the g_warnings now in the unit tests and that fact that failing to set extension data left the extension bit untouched.
