GStreamer | gst-plugins-good | Ver: 0.10.20
Summary: rtspsrc could not receive data from RTSP server because
of the firewall in the Internet
Product: GStreamer
Version: 0.10.20
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-good
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: chao.zhang at access-company.com
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: 2.19/2.20
GNOME milestone: Unspecified
Please describe the problem:
Rtspsrc sends `PLAY' method after `OPTIONS, DESCRIBE, SETUP', then the RTSP
server begins to send data to the client. But the data cannot be received by
rtspsrc because the firewall in the Internet blocks these data by default.
Especially, when your client machine is in a NAT network environment, the
firewall will block all the data comes from outside by default except your
client machine initiates this connection.
This will make rtspsrc plays a RTSP clip failed.
Steps to reproduce:
1. Construct a NAT environment which blocks all data from outside network by
default.
2. Use rtspsrc to play a rtsp movie. E.g: a movie from m.youtube.com.
3. Rtspsrc cannot receive any data and playout fails.
Actual results:
The playout fails and rtspsrc reports that it receives no data.
Expected results:
Rtspsrc should do something to make data passes through the firewalls.
Does this happen every time?
Yes
