Broadcast, live stream?

Hello. I have a few questions regarding broadcasting live video streams in H.264 encoded format. I am new here and have little knowledge about the topic. What I am interested in is how can I broadcast (multicast?) live video streams over the internet to multiple viewers? I have video content on a HDD, encoded in H.264 which is constantly updating (I add new files, remove old ones and so on, kind of like a TV channel or Internet Radio but with video), I need to feed that content to a live stream server somehow. It should not be an "On Demand" stream, but "live". What software do I need for this? What do I need to broadcast my so-called "live TV" to end users and what software should I use to auto "feed" the server with new content? If you have any thoughts or can give me links to helpful resources I would appreciate it a lot! Thank you!

I already took a look at that software. I don't sure if it fits my needs. Lets say I have a video source which is an uncompressed live stream. I need: to capture that stream, compress it using H.264 encoding, then rebroadcast it. The time buffer I have is 8 hours (I can broadcast the compressed stream after 8 hours after getting the original stream). Now, how do I do it?

AS3 - 1) Countdown Timer to the designated Date for Live-Broadcast-Event yet to take place; 2) Detect End of Live Stream on FLVPlayback with FLVPlayback.isLive = true - ActionScript 3 - flash cs3 cs4

Hi folks,
Ronny's here again on forums, having particularly 2 (two) questions/problems to resolve:
1) Countdown Timer to the designated Date for Live-Broadcast-Event yet to take place
2) Detect End of Live Stream on FLVPlayback with FLVPlayback.isLive = true
attached is the .zip file (as3_Countdown Timer_ver 1.0.1_by Ronny Depp.zip) with all flash source files containing:
a) The FLash Source (file: timer_module.fla) - (FLA flash source file - Flash CS3 Professional, Flash Player 9, actionscript 3.0)
b) com.othenticmedia.utils.dateAndTimeManagement package including 2 .as actionscript 3.0 Class files.
       i) com.othenticmedia.utils.dateAndTimeManagement.DateAndTimeManager Class in the said package. (file: DateAndTimeManager.as)
       ii) com.othenticmedia.utils.dateAndTimeManagement.CountdownTimer Class in the package. (file: CountdownTimer.as)
c) The compiled SWF file version of this Application's blueprint. (file: timer_module.swf).
What i need to confirm is: ........................................................ see the next post of mine. (for Problems need to be Resolved)

Problems to Resolve:
Problem#1) - Countdown Timer to the designated Date for Live-Broadcast-Event yet to take place.
Problem#2) - Detect End of Live Stream on FLVPlayback with FLVPlayback.isLive = true;
Problem#1 Description:
I need to pinpoint the Logical TimeSync Exception, i am still unable to figure out. That is I'm using a webservice in my Application to Synchronize the Time with the actual ET (eastern time) with accomodation of auto-adjustment for EDT GMT-4 (eastern daylight time) & EST GMT-5 (eastern standard time), times. I am using the zipcode: "10012" to pass it to the Web Service in urlRequest object, to retrieve the Current ET eastern time according to EDT & EST time settings for Manhattan/Brooklyn areas or others within New York, NY 10012.
Currently the Web Service is returning accurate date/time based on local EDT GMT-4 daylight time.
Is there some defined set of dates for EDT & EST times for New York region that I can check for to ensure the correct Dates/Times for Eastern Time in New York area ??? I am using NY zipcodes because i am sure to get correct ET values.
The Major Problem Part: is I need to correct the time by 2 seconds or approx. 2 secs, some millisecs.
When I retrieve the Time Value from WebService, it lags behind for 2 seconds as compared to DateObj i create using computer's local time, on my Windows XP Service Pack 2 with Automatic Updates turned-on. And I'm sure about my Windows will be having latest updates for Time Management already installed. I also added the 2 secs. to the TimeSync(ed) Date to make correction to this Date obj.
I call my custom fucntion addSeconds(dateObj:Date, secs:int) to add 2 seconds to the Date by Converting Seconds to Milliseconds.
Please comb through the as code in files attached and Help Me Out !!!
Problem#2 Description:
Secondly I need to Detect the End of Stream state while using FLVPlayback component, an rtmp:// live Stream from FLASH MEDIA SERVER.
I need to Play a YuMe Post-Roll Ad when Steam Finishes/Ends.
Live Broadcast Stream Event starts every night on Wednesdays & Saturdays exactly at 10:59 PM EDT GMT-4.
Live Events only Streams/Broadcasts the stream for 50secs. exactly. When [playback stopped] it plays a PostRoll Ad and after the CountdownTimer again comes back to life. The Next upcoming Event is calculated & the Countdown begins until Next Event's time/date is reached.
Here is the code on the frame 1 on the MainTimeline: (rest of the params like source, volume, skinAutoHide are Set using Property Inspector for FLVPlayback instance on Stage)

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.

Using netStream.time on rtmp live stream (broadcaster!=receiver)

I am trying to synchronize a live stream (which is
broadcasted from the flash player plugin) with some scripted
actions. The problem is, that the displayed frames of the rtmp
stream do not correlate to the netStream.time property on the
receiver side. In fact, i do not understand at all, how the
property is rendered on the receiver, since i can not recognize any
dependencies to e.g. bufferLength.
Does anybody now, how it is calculated? I tried with Red5 and
Wowza and they seem to behave similar. I guess, FMS would not make
any difference (if so: lease let me know!), since i assume that the
property is rendered during the encoding process i.e. by the
plugin.

Hello Jay,
thank you for your answer! NetStream.send() seems to be at
least a possibility to solve my problem with a workaround.
I just want to synchronize the time information of the up-
and downstream: both should have the same time information when
they show the same visual content (which i called "frame" in the
former post).
What i would suppose the netstream.time to be is that if i
shake my camera on upstream.time=10.0 then downstream.time should
equal 10.0 when this camera shaking is played back. This is the
behaviour that i am used to from streaming prerecorded FLVs. But
with live streams things work out diffferently.
In fact my downstream.time is bigger than upstream.time. And
i can not imagine how this can be. If i streamed up for let's say
20 seconds and i start the downstream after about 10 seconds, i
would expect my downstream.time to start with 10 seconds and then
increase continually. But against this, my downstream.time starts
with something above 20. How can this be? Or back to my initial
question: how is the downstream.time rendered?
This behaviour seems not to be dependent on the
downstream.bufferTime.
With netStream.send() i could send the upstream.time
information via the upstream to render an offset for
downstream.time on receiver side. This should work (have to check
it), but is a workaround, no "clean" solution.

Using Broadcaster with Internap CDN for live streaming

Has anybody successfully used Broadcaster with Internap's CDN for live streaming?
If so how are you configuring broadcaster?

What are your current settings in FMLE ?
What is your input feed? from webcam? external HD camera? Encoder card?
If your connectivity approved you can raise up the bitrate and set higher output size.

Live Streaming/broadcasting and latency

Hi,
Can any one of you provide me with details on how much is
latency experienced when live video and audio is streamed using FME
+ FMS + FP.
Ex: A 256 kbps streaming.
Does FME , FMS and FP uses buffering concept? if so, how can
that be tweaked to deliver the live video with reduced latency. Is
it possible to achieve a latency of less or equal to 1 second and
how.
We are using Web Cam, Windows Media Server, Windows Media
Encoder and Windows Media Player to achieve the live streaming of
events. But we end up having a latency of 8 to 15 seconds (in LAN).
This is the major challenge we are facing. We are trying to
find out if FME, FMS and FP can overcome the issues being faced.
TIA,
Mohith

Hi Kevin,
Thanks for the information.
What will be the latency in second, from the point of
capturing till the end user viewing in the FMP, over the internet.
In some article i had seen the information which said that
having 2 seconds of buffering would be appropriate for the end user
to have acceptable limit (performance and quality) for viewing.
Having said 2 seconds of buffering configured, it will sure
add 2 seconds of latency.
This for sure is acceptable if there is no user action to be
expected (Ex: Telecasting of live sports event).
Whereas for senarios like live auctions(of paintings) on the
internet where participants can be present at the auction location
as well as taking part in the auctioning through internet, every
second of latency counts.
your thoughts.
Regards,
Mohith

How can I do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder which does not have firewire out/input? it comes only with a component video output, USB, HDMI and composite RCA output?

I need to do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder (http://store.sony.co...ber=HDRAX2000/H) ..this camcorder model does not have firewire out/input ..it comes only with a component video output, USB, HDMI and composite A/V video output..
I wonder how can I plug this camcorder to the firewire port of my laptop? Browsing on internet I found that Grass Valley Company produces this converter http://www.amazon.co...=A17MC6HOH9AVE6 ..but I am not sure -not even after checking the amazon reviews- if this device will send the video signal through firewire to my laptop, in order to live streaming properly? ..anyone in this forum could help me please?
Thanx

I can't broadcast with the built in iSight webcam... how would I zoom in or zoom out? or how would I pan? I've seem people doing it walking with their laptops but that's not an option for me... there's nothing wrong with my USB ports but that's neither an option to stream video because as far as I know through USB you can't connect video in apple operating systems ..you can for sure plug any video cam or photo camera through usb but as a drive to transfer data not as a live video camera... is by firewire an old interface developed by apple that you can connect all sorts of cameras to apple computers... unfortunately my new sony HDR-AX2000 camcorder doesn't have firewire output...

Trying to add metadata to a live stream completely fails

Hi. I've been following this document http://help.adobe.com/en_US/flashmediaserver/devguide/WS5b3ccc516d4fbf351e63e3d11a0773d56e -7ff6Dev.html for adding metadata to an FMS live stream from a Flash widget.
I've created a stripped-down version of the code (listed below); the same as the original code except the controls are removed. It works fine only if I comment out the ns.send calls. If I leave in the ns.send calls, no clients are ever able to view anything. I'm using a stock FMS 4.5 install on Amazon EC2 -- the AMI is ami-904f08c2. And I'm compiling the swf using Flex SDK 4.6 on Linux with the command "mxmlc -compiler.library-path+=./playerglobal11_0.swc -swf-version=13 -static-link-runtime-shared-libraries Broadcaster.as".

Also, emitting other events in the ns.send calls works; eg. if I do ns.send("blah", "onMetaData", myMetadata), nothing happens (because there's no "blah" function to do anything), but at least this doesn't cause the entire stream to fail.

Dynamic Bitrate Switching on Live Stream

I have FMIS 3.5. I've installed it with pretty much all the default values. I haven't changed any of the settings in either the LIVE or the VOD applications.
Dynamic Bitrate Switching is working well for VOD, but not working at all for LIVE streams. Doing a regular bandwidth detection on both the LIVE and the VOD applications give similar, high bandwidth results. However, the LIVE application NetStreamInfo.maxBytesPerSecond is showing a very low bandwidth capability of around maxBytesPerSecond = 19016, where as for the VOD its achieving around 637110. I can play a single LIVE stream of a high quality smoothly without any error.
I don't know if this is relevent but I'm getting some error messages occassionally in the log of the live application saying : Dropping application (live/_definst_) message. Clients not allowed to broadcast message. These messages aren't consistent, and don't coincide with trying to use bitrate switching.
I have tried downloading the Adobe sample StreamSwitching.fla and it won't play the LIVE streams at all. Using the opensource Longtail Video player it just always defaults to the lowest stream. Here is an example: http://www.ltscotland.org.uk/testbed/live/livestream2.asp
Can anyone suggest what the problem might be here? And any possible solutions?

Thanks,I have read that article. Based on that article the NetStreamInfo.maxBytesPerSecond is not an accurate measurement to base dynamic switching on. This seems to be the basis of the bitrate switching in both the longtail player, and the adobe examples that I have tried. That article suggests using the dropped frames property, in conjunciton with bufferlength to determine if switching is neccessary. Unfortunately I can't seem to find a player online which handles this successfully. That being said, I can't believe I'm the only person trying to implement dynamic bitrate switching for live streams so surely there are some players out there which can do this successfully? If anyone knows of any code available which does this successfully I would appreciate knowing where! The examples provided by Adobe https://www.adobe.com/cfusion/entitlement/index.cfm?e=fms35 unfortunately don't work either.

Problem relaying live stream using different urls

Hi,
I have setup QT Broadcaster to announce a stream to my qtss.
I announced the stream to a directory live/stream.sdp
This works without a clinch when using the same URL for viewing, e.g.
rtsp://rtsp.myqttss.com/live/stream.sdp
If I create a symlink (or simply copy the sdp file) from live/stream.sdp to test/stream.sdp and try to access the stream through
rtsp://rtsp.myqttss.com/test/stream.sdp
it does not work anymore. QT Viewer will connect, but does not play the stream.
I am wondering why this is. Is the mountpoint relevant for accessing the stream? All neccessary information should be contained in the sdp file.
The reason I would like to do that is because we have a payment module for QTSS that will use a 'virtual' address to dispatch a stream to the client. This works perfectly for non live content.
Thanks
NikWest

Ok.
No problem now.
Thanks.

Live streaming just stopped

The server is up and running, the VOD items work fine. The server recognizes the streaming application when I output to the server, but we cannot view the stream. ? This was working fine and all of a sudden, nothing. Any ideas?

Yes, our live streams were working fine than just stopped. When I start to broadcast a live feed. The server sees the input but not able to view the live stream. VOD works fine. We are looking into the server itself. There was a pushed update and after that this issue popped up. All the FMS application services look to be started and running, but still nothing. FMS sees when a user connects to the live stream and is outputting, but nothing on the Flash player end.?

How to make a Countdown timer Script for Live Streaming

I have flash media server...
Here's a Scenario:
User wants to do a Live broadcast.. But.. they don't want to
just press record and have it starting Streaming Right that second.
They need a Delay to prepare for their Live Broadcasts.
Whats the best way for a script for a user to decide how much
time delay they need before Recording Starts?
Ideally it would look like this:
There is a separate window that allows the user to set the
Self-Timer which will give them time to get ready for their live
broadcasts.
User sets length of Time Delay: 30 seconds, 1 minute, 2
minutes, or even up to 5 minutes.
User presses Start Broadcast or Record Button to start
streaming Live Video.
Then.. the Countdown Timer starts... and it displays in Big
Digits... the countdown on their screen... "3...2...1...
Broadcasting Live Now!"
How would I do this?
Hope someone can help

Open the widget library panel and follow the link to Adobe Muse Exchange.
There you find a fine little widget collection, named Andrews Prototypes.
Load it, double-click the file, and in your library you will find a countdown widget.

Broadcast, live stream?
