Live video streaming through red5

hi all,
I'm working on a video Audio chat Application developed in flex, Air and red5 as media server.
Basically the chatting will be between one-to-one user based, where one client(webUser) is going to signin from the website and selects a user from the list of online users.
The other person is online from his desktop tool developed in air application.
The communication between these two users is through webService. Now as soon as the Air user gets request for chat from webuser he accepts it, a chat window opens and connects to red5.
We are streaming the live webcam video,Audio and messages through red5. we are publishing Air users video to webuser and playing webusers video to airuser. we are using the same code in both the applications for connecting and streaming but the video is playing in the webuser end for few minutes and in the air application the webuser video just appears for few seconds and stops saying NetStream.play.unpublishNotify. That is the actual problem.
I also test with the same thing with two web application and here publishing is working at both end and both user can able to see the others video.
So main problem is between Air and web application, the video stops in few seconds. Please let us know if there is any security restriion in AIR or any thing else which I m missing.
Any help is appreaciated.

Hi,
I need show three live image from three ip cameras in one window... how can I do this?? can you help me??
thanks

Variable bitrates for Live Video Stream through DSS

I was wondering if there was a way I could do a live broadcast using QuickTime Broadcaster and Darwin Streaming Server (DSS) so that users viewing the live feed see it at different bitrates according to their internet connection.
I've been looking through the administrator's guide, but it doesn't say anything about doing reference movies with live broadcasts so I wanted to ask here.
Dell Server, iBook G4 with QT Broadcaster Other OS Debian GNU/Linux 3.1 running DSS 5.5.1 using latest QuickTime Broadcaster

Would I have significant performance problems with QT Broadcaster encoding the same video at three different rates?
Not really since you'd be using three separate Macs with three separate copies of QT Broadcaster. Of course you'll need sufficient bandwidth in your network/Internet connection to handle the number of feeds you expect. I haven't tried to plug a single FW camera into three separate Macs at once, though in theory it should work (I did it with two once just as an experiment and it seemed to work OK).

Does anyone know a work around to broadcast live (in real time) via video stream through a BC website?

Does anyone know a work around to broadcast live (in real time) via video stream through a BC website?
~Leritha

There is no work around. You would look to use a service, like Twitch, you get a embed code for the live stream, you put that on a page and away you go. All depends on the service your using.

AAC audio causes stuttering in live video stream playback

I am using the Spark VideoDisplay component and setting the mx_internal bufferTime to 0. (videoDisplay.mx_internal::videoPlayer.bufferTime = 0) I am doing this because I need to have the absolute minimum delay in the live video stream. I am broadcasting video files as a live stream using ffmpeg, through Red5, then to the client. ffmpeg is not re-encoding the video or audio. I am using h.264 video format. I have tried encoding videos using Adobe Media Encoder and ffmpeg.
When I have a video stream only and no audio stream this works fine, but when I have an AAC audio channel with the video, I frequently see the video jitter badly. It looks like the video is quickly going forward and back a few frames. When this problem occurs it will go on for some time and sometimes eventualy starts playing normal. When the video is playing normally the audio sounds fine. When I play the videos in a regular media player (like VLC) they play and sound fine. Also if I use an mp3 audio channel I don't see the jittering
Does anyone have any idea what the cause of this problem might be or how it can be resolved?

Ah, yes, I am not serving high-def video myself. H264 is probably better, but my understanding is that you need hardware acceleration to get good performance from it (again, not an expert on the topic, that's just what my understanding has been...)
This document [pdf] may have some usefull info on choosing an optimal encoding for your needs.

Live Video encoding through a flash-enabled web page?

Flash Media Encoder is a great stand-alone application, but
I'd like to know how to encode live video directly using a
flash-enabled web page. E.g., User visits web site and can send his
or her live video from their camera directly to the server. I've
been looking for examples, sample code, and even 3rd party
components. Any pointers would be appreciated!

I asked the same question in a post I made yesterday, then noticed your post which predates mine by
a year and a half. Unfortunately no answers, though I was able to find this page on the Flash Media Server documentation:
http://help.adobe.com/en_US/FlashMediaServer/3.5_Deving/WS5b3ccc516d4fbf351e63e3d11a0773d5 6e-7ff0.html
The first paragraph is about using Flash Media Live Encoder, but the rest of describes how to code a custom capture application in action script that will capture the video and send it to the Flash Media Server. And there's code samples with the article. Since the code compiles an swf file, I imagine all you have to do is serve the page through any web server (the article places it in a FMS application directory) and you have live video streaming. Note that you need a media server (Wowza is an interesting alternative to FMS), but I understand that Flash Player 10 can do peer-to-peer video with another Flash Player 10. Hope this helps, this is what I'm going to try.

How to play live Video Stream with Flex?

I'm trying to get Flex Builder 3 to play a live video stream with Flash Media
Server and Flash Live Media Encoder.
I'm able to stream pre-recrorded (vod) flvs in flex from flash media server.
I'm able to stream live video using Flash/FMS/Flas Live Media Encoder, but not
with Flex.
This code streams pre-recorded Video on Demand flvs, but not live streams:
If I change source to "rtmp://localhost/live/livesream.flv, I get nothing.
What am I doing wrong?
<?xml version="1.0"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:HBox>
        <mx:Label text="RTMP FMS 2.0"/>
        <mx:VideoDisplay
            autoBandWidthDetection="false"
            source="rtmp://localhost/vod/Legend.flv"/>
    </mx:HBox>
</mx:Application>
Oh and sorry for the double post. I didn't know there was a seperate FMS forum.

That worked! Thanks *very* much. Stupid of me to forget to set the live attribute to true. Also removed the .flv. BTW: what video component do you prefer?
Here's the working code:
<?xml version="1.0"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:HBox>
        <mx:VideoDisplay

Live video stream to both Flash and iOS problem

Hi everyone, I'm Lucas. I Have learnt how to deliver a single live video stream to both Flash and iOS from this video
But after that I got a problem with the ".f4m" file and ".m3u8" file (I think) like this video below here. I don't know what happen with the server because my camera is still working perfectly.
I now using Flash Media Server 4.5
Does anyone know how to fix it?

Try this :
1: stop any stream.
2: go to root_install\applications\livepkgr\events\_definst_\liveevent and delete any .stream file that is in there
3: Go to root_install\applications\livepkgr\streams\_definst_ any livestream folder that is in there for example if you streamed with name livestream12 there should be a folder with the name livestream12, delete it.
4: Then try streaming a single bitrate stream by adding to the FMLE the following parameters
FMS Url : rtmp://localhost/livepkgr
Stream: livestream?adbe-live-event=liveevent
5: go to sample player and add this url to the field : http://localhost/hds-live/livepkgr/_definst_/liveevent/livestream.f4m
*If you have a public IP do the following :
1: go to http://www.osmf.org/configurator/fmp/#
and add this url : http://public_ip/hds-live/livepkgr/_definst_/liveevent/livestream.f4m (replace localhost with your public IP)
and from the advanced tab say that it is live.
Give it a try!

Switching video source for live video streaming

Is it possible to switch the video source from a video
capture card to a standalone video during live video streaming? We
are streaming live TV and we want to skip playing any
advertisements.
If this is not possible, what is the best way skip playing
any advertisements? Do we have to do it at the client player level
i.e. catch an event from the video player and play a predefined
video when the live video stream is stopped?

Thanks for reporting your fix. That news could be very important to those who delete events from their hard drive to save space, but may want to reload them later to do some editing.
It sounds like the key is re-importing with exactly the same name as before.
Just curious: What kind of camcorder? Was it MiniDV tape? Flash? Hard drive? DVD?
It strikes me that with tape it might be difficult to reimport an exact match. If you start on a different frame, the pointers could be off. But if that is not the case, it is very good news.

How do you auto reconnect a live video stream broadcast in flash action script 3?

how do you auto reconnect a live video stream broadcast in flash action script 3?
so i don't have to ask people to refresh the page if the connection drops
i copy pasted the live video stream broadcast files and script from here;

Why don't you use several layers with appropriate alpha properties, and move these layers according to the mouse events?

Director 11 using a webcam or live video streaming input

I am looking for a solution to use input from a webcam or from any other live video stream in Director 11.
I have tried using a Flash component but this does not work.
The MyronXtra does not work with Director 11 too!
Anyone has an idea?
Thank you

Mplayer and multiptle simultaneous video streams through xv

While I was using nvidia drivers a while back, I could playback multiple simultaneous video streams through xv in mplayer without any problem. After recent change of video card and consequential move to open source radeon drivers, I've observed that I can play upmost one stream with gmplayer (it spits out an error about problems with opening the selected video out device - I can playback more files simultaneously using basic mplayer, although it spits the same error in console with every successive instance). Could someone enlighten me whether it's a standard behaviour of xv with radeon driver or maybe the problem lies elsewhere and it's omittable somehow?

Tried it, but to the same result
What I found out is that the user can play videos from console with framebuffer at least. Not that it helps..

Live video stream play permission on server-side

I have a live video stream application one-to-many for
example, and i want to send video only to few clients, not to all.
Like:
quote:
application.onConnect = function(client, canSeeVideo) {
// canSeeVideo = boolean
this.acceptConnection(client);
if (!canSeeVideo) client.receiveVideo(false);
// and after this, can be swich to TRUE or FALSE ?
client.receiveVideo(true);
I only want to do restriction for Video, from server-side
with FMS, or if can't be possible.. how can i put for example a
black screen on video ? :) and after can be removed, etc...

1.
necesary client.receiveVideo() and client.receiveAudio()
server-side functions
Thank you fmslove for you trying to help me but
client.readAccess property can NOT be set after client
connection was accepted, and for me is useless. Any other
solution(s) ? i strong recomend to Adobe FMS dev staff to implement
this feature because is refering to security client-side solution
from server-side. I have bad experience with users trying to modify
the Flash Player (plug-in) run memory and set values for my swf
without my accept, and is nothing that i can do from client-side
like NetSream.receiveVideo(false) on many-to-many or one-to-many
live A/V stream.
2.
a necesary server-side video encoder solution better than
Sorenson Spark
If in future FMS staff from Adobe will implement this
necesary security feature on server-side like a copy of
NetSream.receiveVideo() function from client-side, i will be happy
if i see a solution to encode LIVE video stream on server-side
because
Sorenson Spark video encoder built-in Flash Player (plug-in) is
very old and unuseful.
If this can't be possible i hope the future Flash Player
version (10) will have a better video encoder built-in than
Sorenson Spark !!!

Live video stream keeps replaying parts of stream.

While watching live video stream the video jumps back and replays what has already played. It doesn't skip forward only replays, no problems with chopping stream or anything else. Thanks for your help.

Dear RahiSC.
We actualy never found the solution to this problem. This issue was only there when we were using BlackMagic Studio cards using SDI link. Now we use Osprey video capture card using composite input and now everything works perfectly.
After that we didn't yet try to resolve the issue when using BlackMagic Studio cards using SDI link.
best regards,
Borut.

Live video streaming not working

My live video streaming is not work properly. I can watch video for a few seconds to a few minutes before it stops. Why??? What can be done to fix this?

I downloaded a new version of the app NDTV , but the problem still persists .
I am using iPhone 5 .
Please advise, if there are any specific updates you are pointing to . Because I dont have any pending updates showing in App store

Audio several seconds out of sync with live video stream.

I did a live stream last week using 282,482,832,1500Kbps streams. What would cause the audio to get out of sync with the live video stream? I'm trying to determine if it was bandwidth related, cpu/memory issue on the FMIS 4.5 server, or an issue with encoding PC exceeding it's limits?
Thanks,
Dave

Which device are you using? Are audio and video coming from the same device or different devices?
Is it a USB device? Try changing the device and see if there is any difference. Changing bitrates will not affect audio-video sync.
