Summary: Parsing SDP file with multicast address fails
Product: GStreamer
Version: HEAD CVS
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-base
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: tero.saarni at gmail.com
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: 2.21/2.22
GNOME milestone: Unspecified
Please describe the problem:
When SDP file has c= field with multicast address the parser fails to remove
TTL part and regards that as part of IP address. See attached files
stream-with-multicast-address.sdp and debug log file
gst-sdpdemux-before-fix.txt.
According to RFC2327 the address is separated from TTL by "/" character but the
code expects whitespace.
See proposed fix in file gst-sdp-multicast-address-fix.patch and
gst-sdpdemux-after-fix.txt for a debug log when the patch is applied.
Steps to reproduce:
gst-launch --gst-debug=sdpdemux:5 filesrc
location=stream-with-multicast-address.sdp
Actual results:
Expected results:
Does this happen every time?
yes
Other information:
Excerpt from RFC2327:
connection-address = multicast-address
| addr
multicast-address = 3*(decimal-uchar ".") decimal-uchar "/" ttl
[ "/" integer ]
