Hi guys I hope that some of you will be able to help me.
I'm trying to stream audio from a live RTMP stream using the NetConnection and NetStream classes. I managed to get my app works without problem on Android, but I have some major difficulty make him play the audio back on iPad. Interestingly, it works in the device emulators when you are debugging, but I guess this isn't really an accurate representation. I tried streaming RTMP in AAC and MP3, but without success to be. I check through debugging that there haven't connected to the stream, however I just get no audio playback.
Everything I read on door to believe that this is possible on IOS that I'm only interested by audio and video not. Can anyone help?

Just an update on this for all of you who come along after me.
I managed to get this working on the MP3 but not AAC (I guess just AAC is not taken in charge?).
My problem was the buffertime. Docs seemed to indicate that it should be set to 0 for live streaming, however he switch to "1" has solved my problem on the particular flow I pointed at.
So, essentially above the justchanged line:
ns.bufferTime = 0;
TO
ns.bufferTime = 1;
Would be nice to know if someone got AAFC works though...
but it seems to be incompatible with the broadcasts.
the required level of SEEN is the basis that there is a live audio feed and does not need to be fancy at all.
Currently, we use JWPlayer but am not bound to her for this project.
Cheers for the help

Have you tried the Sound class computeSpectrum() method? Since flash V9.x, it can calculate the spectrum on RTMP. The link to the API has a complete example that makes a wave form. It calculates a value between-1.0 and 1.0 for the values 512, 256 for the left and right channels 256.
You can group them into blocks and use the data to calculate your audio levels. Simply to group a bunch of values and therefore one that shows the average of the values to simplify. for example, 4 bar uses the average of the values of 0-64, 65-128, 129-192, 193-256 for the left channel... You get the idea.
I'm working on an online radio application and I am very disappointed to see that the BB 10.1 Simulator (10.1.0.1483) does not support the HTTP live streaming of multimedia files (MP3) M3U.
I get the following message in the log of the device:
and also when you try to navigate to the URL in the browser of the Simulator:
The media file is from and not supported type or could not be loaded. It can not be played.
I would like to know if the BB 10.2 Simulator supports HTTP live streaming of MP3 files, or do I have to buy a real device?
Best regards

Hi @burakk,
My apologies for the late reply. Unfortunately, for the OS versions on the market to date, support for media playback on the Simulator is very limited. This is mainly due to problems of codecs required license. There is a support very limited no playback video and audio (uncompressed audio files in the WAV only). In later versions of OS Simulator, we might have the software decoding - if that happens, your use case would be satisfied then.
We have installed FMS 4.5, including Apache 2.2 on a server of Windows 2008 R2 64-bit according to the instructions provided in the video which can be seen here:
Accessing the test page for the server works fine for HTTP Dynamic Streaming and RTMP Dynamic Streaming samples. However, when we try to use HTTP Live streaming of the samples on the test on an iPad via AnyConnect web page, we see only a blank page with a small icon of Abobe Flash in the upper left corner which is basically saying that the Flash has been detected on the page and is not supported by the iPad.
The video above shows HLS working on an iPad with no additional installation steps. Can you hep?

In streams remotely, the error was: "there was an error decoding of this media. "The multimedia format not supported".
What's wrong?
What can I do?
Now I know what was my mistake: the URL does not contain a stream, only a playlist (PLS) with multiple URLS to to access the stream. For more details you can see:
I have some video blogs that I would turn into animations of CA. However, I don't want to have to re-register the. Then I take the archived videos and use it to create an animation of CA, rather than using a live stream of a webcam?
You can use pre-recorded images with a reader who Ch acknowledges. I use ManyCam and it works very well for video and audio.
I was hoping to get some suggestions on how we could better use Acrobat Connect Pro for live stream an upcoming event. Every year we organize an event with a live and online audience. Traditionally, we asked our animators to talk into a microphone that is connected to a SOUND system in the room and then a separate microphone connected to a cell phone photos to the top of the audio that come out of the sound system and passes it on to the way to connect. I think there must be a better way to do it (maybe using a mixing console?), but I don't know how it works. Does anyone have any ideas/suggestions?
Similarly, anyone has any ideas on adding a video stream live? Ideally, I'd like to broadcast a video feed a resolution about 480, but I don't know if it's realistic. Any ideas people perhaps would be greatly appreciated.
I've produced dozens of events like yours. The best solution is to find some kind of audio output on your SOUND system port. Maybe it's a headphone jack, but it works very well. What connection you can find, get a cable that connects to this port at one end and the other end to fit into your PC/Mac using either micro-dans or USB. You should only configure Flash to watch this entry. The best way to proceed is to run the Audio Wizard of Connect.
Is someone can you please tell me how can I play http live streaming from OUT 3.2 for Flash player, iphone, ipdad, HTML5 player, Android and other devices?
I use Amazon Cloud & Flash MMedia Server 4.5. I would like to take one of my videos of outputs (a static file) and turn it into a live stream. People can view this video (synchronous). I use Flash Media Live Encoder 3.2, but it only capture video from devices like the camera...
How can I do?
See you soon.
Hi Huy,
Please find the attached zip file where I wrote scripts for you to deploy to your local FMS server, in the context of option 2:
You may want to follow these steps:
1. unzip the file.
2 deploy FLVpublishonLoad (in which case your saved file is a case of use FLV) on your server for businesses
3 deploy toPublish on your server remote aws
4. make sure that correct the path for the AWS in application FLVPublishonLoad @ No. 19 line:
Please mention your aws instead of localhost instance host name and the application name.
NC. Connect ("rtmp://localhost/toPublish");
5. go in the administration of your local development server console and load the instance of FLVPublishonLoad, as shown in the image of howtoLoadfromAdminConsole.png attached to effect refrence.
6. it will automatically connect to the application of the "toPublish' on your remote server and start publishing your file local vod as a live stream on your aws instance
7 start your subscriber application and subscribe to the feed you used in FLVPublishonLoad app for Stream.get () method, see line #29 and the file subscriberScreenExample.png to illustration.
some things to note here:
1. I removed the sample.flv and the 'sample1_1500kbps.f4v' to keep the zip size down.
2. you need to put your data online #55 stream name where you call mystream.play)
3. the name of the stream you specify in Stream.get () will be used by the subscribers.
4. If your use case is mp4, please use "MP4PublishonLoad" instead of the "FLVPublishonLoad" application

I work with the live broadcast for a few weeks, using flash.media.Camera and flash.net.NetStream class. I have not found any place where the codec is specified, which is used to encode live stream.
Anyone know what codec is used, and if there is a possiblitiy of using the H264 codec for live streaming? I found that the live broadcast with the h.264 codec seems to be possible with the encoder flashmedia (http://www.adobe.com/products/flashmediaserver/flashmediaencoder/). Is this possible with flash player only?
Thanks for your help,
Marc
Hi Marc,
Flash Player does not support H264 encoding. Only video codec supported by Flash Player is Sorenson and it supports two audio - Nellymoser and Speex codecs.
So, if you need H264, you use GFFE or any other partner supported encoders.
I use FMS for a few weeks and feel relatively comfortable with it, but is currently experiencing some problems connecting to a live stream in a a video conference-type application.
I suspect I'm leaving a few small not to outgoing not, but cannot see what is this step.
I have a client application open the video camera, connect to the FMS and publish his feed live camera on the server. Something like this:
It should publish the feed live called 'user1' on my FMS instance. Indeed, using the administration console indicates that this connection has been established, and a 'Live' stream exists with the name "user1".
My problem is when I try to open in this workflow with a second client:
However, I get the errors "NetStream.Play.StreamNotFound". It seems relatively simple, but it clearly a small not miss somewhere. Maybe a second pair of eyes can help me find my problem?
Thank you.
Replace
remoteStream.play ("User1", 0);
by
remoteStream.play ("user1");
the second parameter of play() is start time with the default value of-2. Zero means play a VOD from the beginning.
See the documentation of FMS for details and the list of valid values.
I just can't live stream. I have two files, a single sender and 1 Subscriber. I work locally FMS test.
I just a video object on each step and the ActionScript:
sender: var rtmpPath:String = new String(); rtmpPath = "rtmp: / test";
var ncBase:NetConnection = new NetConnection(); ncBase.connect (rtmpPath);
var ns:NetStream = new NetStream (ncBase); local_sender.attachVideo (camera.get(2) ()); NS. Publish ("testVideo", "Live");
the video object instance name is local_sender.
the Subscriber: var rtmpPath:String = new String(); rtmpPath = "rtmp: / test";
var ncBase:NetConnection = new NetConnection(); ncBase.connect (rtmpPath);
var ns:NetStream = new NetStream (ncBase); local_re.attachVideo (NS); NS. Play ("testVideo");
I can see video camera in the sender file, but in the Subscriber nothing. In the flash media server console, I see 3 streams. create one with the name that I and the other two generic, like CBAoQD6H...
How can test is the output stream is really going out and if so, if the flow in the problem? I do not have a main.as file in my application folder. but I tried to put a there is flash 8 samples and tutorials and did not work.
any help will be much appreciated.
Thank you
now it's working. I forgot to attach the video in the netStream (file sender):
I'm testing an application I created. It's basically a 2-way A / V chat, with a text chat application on there also.
Each user publishes a live feed, which is recorded on the server and the resentment then back down the other user.
I tested it locally all right, so I registered at Influxis on their nitrous plan to give it a try on the Internet.
Each stream publishes a 32 Kbps video + audio stream 8 Kbps. Each user has a fast connection to broadband, with around one 140 ping on the server.
Over time, about 10 minutes or so, far enough out of sync live streams. It may take more than 20 seconds for the stream to reach the other person, do a chat 'live' completely useless.
If I stop and start the stream, he brings everything online, so I consider this as a potential solution.
I would really like to know why this kind of thing happens, how can I minimize and how to recover from him when that happens.
Any help would be appreciated!
Increase the rate of audio at 22. This will rid the latency app, not what you expect, but apparently it works.
after update to adobe flash player for 13.0.0.182 version any live stream on youtube channels suddenly stopped working. other youtube videos play fine.
