GStreamer Launch RTSP Server for ReStreaming IP Camera H264

由 耗尽温柔 提交于 2019-12-11 05:18:38
问题 I am going to use multiple clients on different computers to be able to view video of an IP Camera stream url. Because the Ip camera has limitations on the number of connected clients, I want to setup a streamer for this purpose. I googled and tried GStreamer with different command line options but not yet successful. Here is a test command line: gst-launch-1.0 rtspsrc location="rtsp://root:root@192.168.1.1/axis-media/media.amp?videocodec=h264&resolution=320x240&fps=10&compression=50" latency

Playing RTP using VLC

由 霸气de小男生 提交于 2019-12-10 13:29:17
问题 I currently have an Android application that is capturing video from the camera and streaming it over RTP. I do not use RTSP. I have created a SDP file that describes the RTP feed. I can open the SDP file in Quicktime 7 and can see the stream, attempting to open the SDP file in VLC does not work. I get the following error: live555 demux error: no data received in 10s, aborting I am monitoring the RTP packets using Wireshark and can see the packets on the network (see example below): 281956

WebRTC: Use same SDP for multiple peer connections?

由 ￡可爱￡侵袭症＋ 提交于 2019-12-10 12:53:34
问题 Is it possible to use same SDP in multiple peer connections? I'm building video conference using WebRTC. The idea is that caller, using some signaling mechanism, send broadcast message to all other users with it's SDP (same SDP for each user) and then users will respond with their SDP. When user receive somebody's SDP, he use it to set remote description, like this: connection = new RTCPeerConnection() desc = RTCSessionDescription({sdp: SDP, type: "offer"}); connection = setRemoteDescription

Bluetooth SDP - where is sdpd?

问题 Where is the Bluetooth Service Discovery Protocol (SDP) Daemon? I'm trying to register a bluetooth service on Debian V8.0 using bluez. I use example code at https://people.csail.mit.edu/albert/bluez-intro/. Everything goes well until I try sdp_connect( BDADDR_ANY, BDADDR_LOCAL, 0 ); which fails. After some digging, I find that the sdp daemon (sdpd) (to which it needs to connect) is not running and in fact does not even exist on my system. What I Tried: I have installed (apt-get) every

pjsua custom sdp

由 ≡放荡痞女 提交于 2019-12-08 06:24:00
问题 I'm using pjsua to create simple SIP UA. I need to insert custom body (SDP) in outgoing INVITE requests. As far as I know, pjsua does not support custom SDP, and I need to use more low-level API to do it. But for now I have to find any rude trick/hack/hotfix to insert custom SDP in pjsua-generated INVITE. So that's the question: how could I do it? 回答1: The seemingly simple solution is to modify the pjsua source. The key is to create a pjmedia_session out of your custom SDP on code paths of

How to send SDP over RTP

由 北城余情 提交于 2019-12-08 05:08:12
问题 I've developed an app which sends RTP packets to a local ip client. So the client has to listen on the specified port (rtp://:@portnumber, on VLC) to play the streamed data. Right now i'm going to develop the code needed to create the SDP file needed to start streaming. My doubt is, how to send this file to the client? At the beginning of the RTP stream? Really n00b at this point. Any help will be useful. Thanks 回答1: VLC specifically supports RTSP , HTTP , SAP protocols for establishing

Playing sdp file (rtsp stream) from http url in android

由 浪子不回头ぞ 提交于 2019-12-04 17:13:28
I have a rtsp stream on my rtsp server in localhost. I would to play this file with the android class MediaPlayer. If I do setDataSource(rtsp://localhost/file.sdp) it works!! My problem is... if I copy the file on my http server and I do setDataSource(http://localhost/file.sdp) it does not work!! I receive an I/O exception. filePath = "http://localhost/file.sdp"; mediaPlayer.setDataSource(filePath); mediaPlayer.prepare(); mediaPlayer.start(); If I play this file with vlc application it works. RTSP and HTTP are different protocols. An HTTP server is not going to serve the data in the same way.
