rtsp to flash, livestream

Postby multiuser » 10 Oct 2008 10:34

hi everyone!

my problem *gg*:

i have a vserver with a running VLC and a rtsp cam running in internet. now i want to get on server one rtspstream from cam and give the video as a flw/flash (or swf?) out on my webpage, because 98% of users has a flashplayer installed. is it possible to stream this in flash from rtsp?

how does it work?

this is wrong?! (swf?)
vlc rtsp://IPADDRESS:554/live.sdp --sout '#standard{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=IPADDRESS:10001/stream.flv}'
vlc rtsp://IPADDRESS:554/live.sdp --sout '#standard{access=http{mime=video/x-flv},mux=ogg,dst=IPADDRESS:10001/stream.flv}'

please help me :-)
thanks a lot!

You have to transcode.

Because you must change file type, that is why transcode.

vlc rtsp://IPADDRESS:554/live.sdp --sout '#transcode{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=IPADDRESS:10001/stream.flv}'
source in /change video type/source out

I think, VLC haven' t support flv format.

vlc rtsp://10.0.0.3:554/live.sdp --sout '#transcode{access=http,mux=asf,dst=172.19.100.254:10001/stream.asf}'

Hello in this forum I found:

Code: Select all

I've tested a nightly build vlc release and it's working. Here is my line : vlc http://mafreebox.freebox.fr/freeboxtv/playlist.m3u --sout '#transcode{vcodec=FLV1,scale=0.25,acodec=mp3,samplerate=22050}:std{access=http,dst=192.168.0.7:1234/stream.flv}' -I http --http-host 192.168.0.7:8080 And, if I use my webbrowser to access to 192.168.0.7:8080 there is a link in the bottom of the page to access to a flash based video player. Wonderful ;) I've put everything behind an apache proxy server so, it's very clean ;)
Maybe help you.

Hi,

is it an AXIS IP cam? If it is, then a way of partial problem solving exist.
The AXIS IP video product output is MPEG4 ES unmuxed video stream, but VLC can't transcode such a strem by one way(don't ask me why). You have mux your video stream before transcoding.
Example with VLC 0.9.2/4

1) AXIS video stream muxing
vlc.exe rtsp://<cam's IP>:554/mpeg4/media.amp :sout=#duplicate{dst=display,dst=std{access=http,mux=ts,dst=127.0.0.1:8081}}
2) transcoding to FLV
vlc.exe -vvv http://127.0.0.1:8081 :http-caching=5000 :sout=#transcode{vcodec="FLV1",vb="1048",acodec="mp3",ab="128",channels="1"}:duplicate{dst=display,dst="std{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=\"192.168.2.247:40221/stream.flv\"}"}

It works, BUT the quality of resulting flv video stream picture is very poor.

ok, i tried:

10.0.0.140 is servers ip address.
10.0.0.4 is IP from Cam.
rtsp://10.0.0.4:554/live.sdp = rtsp stream from cam

1. vlc rtsp://10.0.0.4:554/live.sdp --sout '#duplicate{dst=display,dst=std{access=http,mux=ts,dst=127.0.0.1:8081}}'
2. vlc -vvv http://127.0.0.1:8081 --http-caching=5000 --sout='#transcode{vcodec="FLV1",vb="1048",acodec="mp3",ab="128",channels="1"}:duplicate{dst=display,dst="std{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst="10.0.0.140:40221/stream.flv"}"}'

-- AND --
vlc -vvv rtsp://10.0.0.4:554/live.sdp --sout '#transcode{vcodec=FLV1,scale=0.25,acodec=mp3,samplerate=22050}:std{access=http,dst=10.0.0.140:1234/stream.flv}' -I http --http-host 10.0.0.140:8080

i always get the videos on kde, but in console (where the protocoll runs) i get
[00000466] avcodec encoder warning: vbv buffer overflow
(flv@0x82df910)

this message i get ol ~0.1 ms. = 1000x and more...
My Cam: VIVOTEK IP7131

Use rtsp and http caching.
Examples:
:rtsp-cashing=5000 and more
:http-caching=5000 and more

thanks for your assistance, however I, I believed leave it now and began from the front. again the requirements:

from the camera (low speed internet, ~760kbit upload) to a linuxserver (with highspeed internetconnection).
this server should share the videostream to use the stream on a website. on this website i want to show the video from Cam!

ActiveX on website is bad, because many users have a firefoxbrowser. it should run in IE and FF. i have read from "videolan-plugin" for browsers. but when i use it, it always "video is loading"... why?

who has an idea?
who kan help me?

thanks a lot!!

Hi
We have the same scheme: IP cam(AXIS) - media muxer(VLC 0.8.6 f) http streaming - public Internet - media server(VLC 0.8.6 f) http/mms streaming - public Internet multiview(sity surveilance, internet show etc.) "How to" about it here (Russian only).

Hi,
I have exactly same tasks. Can I find somewhere an english, french or german translation of the russian howto?

And btw - I would prefer to transcode to HTML5-videostream if possible?! Else flv must be the solution. Request visitors to install the latest browser version is ok for me, even better then asking visitors to install several plugins and codecs...

The original post is some years old - perhaps someone did new howtos for streaming live video on websites using vlc-commandline server? Would make me lucky :)

My setup:
Low-bandwidth ip cam connected to internet where a high-bandwidth server should take over the stream, convert it into html5 or flv stream so that I can put it inside my website.

Thank you very much for any recommendations?

Greetings,
Dr. Zoidberg




Thank Chromium-Browser: It translated the russian thing perfect: Its not what I am looking for. It just streams and proxies and recodes the stream, but you still need a special active-x component for the clients (IE required) to watch the video on a website. Thats no solution. Is there another option just using the browsers-onboard video-functionalities or flv to show the stream?
