Live Video Streaming to Server
Locked
 
|
Hi, I have some devices(like rpi) that I want them to stream to a server and
I want to show the stream in a server/website from browser. This seemed fairly simple at first but as I go through some examples I get more confused. simply: device(s) stream to server and clients watch this streams My first approach was setup an rtsp server, which I failed to understand. Is this exactly what rtsp servers do. I am looking for advice on how to do that. Also, I want to use webrtc stuff. Can I connect rtsp servers with webrtc, if so what gstwebrtc is for. Thanks! -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

the easiest stream i got was using hlssink,
gst-launch-1.0 videotestsrc is-live=true ! x264enc ! mpegtsmux \ ! hlssink playlist-root=https://your-site.org \ location=/srv/hls/hlssink.%05d.ts \ playlist-location=/srv/hls/playlist.m3u8 and video.js on the other site rtsp is black art. hard to find info.

Rtsp really felt like black art. I think it is an expertise on its own. Maybe
you need to be a dark lord to understand it :) For the clarification, this pipeline streams video to the rtsp server and video.js listens to it, right? And would something like this be sufficient for the server? https://github.com/GStreamer/gst-rtsp-server/blob/master/examples/test-video.c or https://github.com/GStreamer/gst-rtsp-server/blob/master/examples/test-video-rtx.c -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

the, videojs has hls (they call it vhs) built in.
like this. just adapt to your .m3u8 location, more here https://videojs.github.io/http-streaming/ <video-js id=vid1 width=600 height=300 class="vjs-default-skin" controls> <source src="https://example.com/index.m3u8" type="application/x-mpegURL"> </video-js> <script src="video.js"></script> <script src="videojs-http-streaming.min.js"></script> <script> var player = videojs('vid1'); player.play(); </script> didn't get to work on android for some reason, i guess is "server issues" as i tried with caddy and not the good old nginx.

I did this recently with nginx and RTMP, using videojs like Yair suggested. I put the details here: https://five381.com/blog/2020-03/rpi-camera-rtmp-streaming/ If you move the nginx server off of the pi to another host I think it will be what you want. That's what I'm doing right now actually.

ah you are using flv/rtmp.
some say its still the smoothest video around does it play well on mobiles?

hls seems to be not supported in major browsers, however my problem is that
what is the role of the server is this scenario. Like okey I used pipeline and video.js but how does my stream reaches the client, over internet? How does it distirubuted? I am trying to create a mental model, so that I will know what tool serves which purpose. I am very new to streaming, I basically know very little about it. -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

yep, many issues
transcoding is the simple(~) step. you have control of your hardware. but distribution, CDNs, multi-client detection of bandwidth and processing capabilities. without going into two-way and the sub 150ms latency humans demand. i had the pleasure of sitting next to a conferencing heavy hitter, requiring servers with 30k open ports to negotiate STUN/TURN and tweaking freeswitch configs for weeks. what a mess. i suggest to start with requirements. is this a LOLs project on a raspi and a 5$ docker node? one2one, one2many (how many)? not speaking as a pro. and would love any info you can gather on the subject the scenarios are so verified and can get complex easily. this is where 3rd party vendors, some of open source solutions, play a big part. and CDNs offering turnkey solutions black art On Fri, Apr 17, 2020 at 11:30 AM strange_loop <[hidden email]> wrote: > > hls seems to be not supported in major browsers, however my problem is that > what is the role of the server is this scenario. > Like okey I used pipeline and video.js but how does my stream reaches the > client, over internet?

But indeed, HLS is not natively supported in browsers in general as it's not part of the standard. > what is the role of the server is this scenario. > Like okey I used pipeline and video.js but how does my stream reaches the > client, over internet?

Streaming capabilities of browser is really poor in fact. That's mostly because the browser offers very high level solution where normal OS gives you low level UDP socket to play with. In the case of HLS the flow is the following: Server: - A server (your RPi) encode and mux into MPEG TS - It then split the MPEG TS in chunk and update a m3u8 playlist - Another server (e.g. nginx) picks these files from disk to make them available to your browser Browser: - The javascript will download though HTTP the m3u8 file and the MPEG TS chunk - As MPEG TS is not supported by browser, it will transmux to fragmented ISOMP4 (yes, in JavaScript!) - Is passes the chunk to the MSE JavaScript interface - That get decoded and played on screen (using a video tag) If you use mpegsash, it's a bit lighter, since there is no transmuxing, you need a JS library still. For video conferencing it's a bit complex, but I'll keep it simple. You need 2 peers, and web server. Potentially a STUN and/or TURN server if the two peers have too restrictive network. 1. Peers call each other through the web server 2. They will use the web server to exchange some info: - Network candidates, for ICE negotiation (nat traversal protocol) - SDP to negotiate the transport and encoding 3. When a "connection" is established things goes peer-to-peer - A DTLS connection is established (server no longer see what is going on) - RTP and RTCP packets starts flowing Of course, when you go into big conference, the server becomes your peer so that it can do video and audio mixing. In that case, the server can see everything that is going on. In the old days, there was some "video streaming" that was using image tags and refreshing it. I think this is still possible using JPEG compression. > > > > > -- > Sent from: http://gstreamer-devel.966125.n4.nabble.com/ > _______________________________________________ > gstreamer-devel mailing list > [hidden email] > https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
