rtp - Streaming using GStreamer

问题描述:

I have got one HD video "ed_hd.avi" on System#1. Would like to stream it over network and play the content from System#2. I am using GStreamer on Ubuntu 11.04, tried a lot on this. Variety of errors makes this objective difficult to diagnose. Will be thankful for getting a working command for the System#1-end and System#2-end.

What I have tried is as follows:

System #1:

gst-launch filesrc location=ed_hd.avi ! decodedin ! x263enc ! video/x-h264 ! rtph264pay ! udpsink host=127.0.0.1 port=5000

System #2:

gst-launch udpsrc port=5000 ! rtph264depay ! decodebin ! xvimagesink

Objective is : Convert avi file to raw video. Stream it from the second System#2.

Thank You.

Could you try the following

gst-launch filesrc location=ed_hd.avi ! decodebin ! ffenc_mpeg4 ! rtpmp4vpay ! udpsink host=127.0.0.1 port=5000 

If that doesn't work then proceed:

Did you try the following? You need to replace his audio bins with video bins

Here replace v4l2src with your video src

网友答案:

I think your problem is the 127.0.0.1 portion. That is a loopback address (check ifconfig lo0 to see the Link encap:Local Loopback for the 127.0.0.1 address). This won't work across two systems, though it might work fine on a single system.

Instead, use the address that is publicly visible for the second machine; check ip addr show or ifconfig output to find the address. Write the actual address for System #2 in the command line on System #1.
