I'm writing an application with AS3 and Flex 4 for Adobe Air 2.0RC and I seem to have run into an interesting predicament.
I am aware of the microphone class and the method to capture recording from them to a byte-array, I am wondering, however, if there is a way to capture another source of audio, say, from an output on an external sound card.
Is anyone aware of an AS3 method of capturing sound from an output?
I'm trying to create a webRadio player, wich different sources. On a click on a button, the player plays the corresponding flow. I would like to display some informations, like : current music, url, description, I think it's possible to have all those informations, because when I play my. files in my audio player (winamp), I've got them. Here is my code corresponding to this part :

I've had FMS running on my local machine for a while and have had a little experience writing FMS apps, but I've just tried recording audio for the first time using the standard vod application and I keep getting a "Write access denied for stream" error. My AS3 code is copied and pasted for various examples and am confident that it works.
I'm running Windows XP service pack 3 & FMIS 3.5.
I've had a look at the vod/media directory and under windows->properties the read-only attribute is ticked. Every time I un-tick this it reverts back to being ticked. I've googled this and MS say that most programs ignore the read-only attribute and that it only really applied to files. I've also tried the MS fix for setting the read-only attribute via cmd and still no joy (doesn't fix read-only attribute or FMS recording the audio after setting via cmd).
I've also tried our dev server install of FMS (running under linux) and am getting the same results.
Here's my AS3 code...
private function initApp(event:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE,initApp);

I am having trouble getting audio stream meta data from an Akamai FMS stream. Everything is undefined and I'm not sure why. I am hoping maybe someone will notice something that I am overlooking. The stream is connecting and playing without a problem I just can't seem to figure out why all the meta data is undefined.
[Code]...
Because the player optimizes framerate, antialiasing etc dependent on the performance capabilities of the platform upon which it is running, it was nearly impossible to ensure animation syncronization w/ audio. If the audio were on the timeline you could set sync params to stream, but if the audio is loaded programically forget it .. well until AS3 ..The following code throttles the player framerate to lock step the animation to the audio .. not perfect but the principal works ..
View 1 RepliesLet me first establish what I want to do:My user is able to record voicenotes on my website, add tags to said notes for indexing as well as a title. When the note is saved I save the path of the note along with the other info in my DB.Now, I have 2 choices to do the recording, both involve a .swf embedded in my site:
1) I could use Red5 server to stream the audio to my server and save the file and return the path to said file to my app to do the DB saving, seems rather complicated since I would have to convert the audio and move it to the appropriate folder that belongs to the user in a server side Red5 app, which I'm not very aware of how to build.
2) I could simply record the audio and grab its byte array, do a Base64 encoding on it and send it to PHP along with the rest of the data that is necessary (be it by a simple POST or an AJAX call), decode it on the server and make the file with the appropriate extension, audio conversion would also occur here using ffmpeg, this option seems simpler but I do not know how viable it is.
Is there a way to stream and audio line level feed rather than the audio from a computer's microphone?
View 1 RepliesI need to take the some stream which is coming from firewire on mac, and then transcode/encode it to perticular bitrates, then stream.I think from firewire to FMLE, its straight forward. How can i stream? How can i give my clients ( say from mobile, or from any player as a http url streaming) stream? Do i need to use Flash media server, if yes can anybody point out the steps to set-up the same.

I have an AS3 swf which users can upload jpg images to my EC2 instances which sit behind and Elastic Load Balancer. The jpg images are converted into bytearray data and sent using URLLoader.load(URLRequest)I make 2 calls when uploading, one to upload a large version, then another to upload a thumbnail version. A PHP script to which the bytearray data is uploaded converts this to a file using file_put_contents($destination,$GLOBALS["HTTP_RAW_POST_DATA"])Is it possible to combine these two requests into a single request which contains both the bytearray data for the large and thumbnail images and 'split' the HTTP_RAW_POST_DATA to create 2 files at the server. This would be better than uploading the bytearray for the large version then using something like ImageMagick to resize the resulting image into a thumbnail which I realise is another option.
View 1 RepliesBasically I want to recreate a sound installation that I made a couple of months ago which used Logic Express and a Tape Delay effect to take ambient sound captured by a mic, delay its output by 3 seconds, and then play it into the headphones. All without recording anything and in realtime.I've basically got this far, which lets me hear the mic input through my headphones loud and clear. Now all I want to do is apply a 3 second delay to the input before it outputs. Do I have to send the audio to a buffer where it can be constantly stored and rewritten?
Code:
//Create a new Microphone
var mic:Microphone = Microphone.getMicrophone();

Does anybody knows if it it possible to stream only audio?
I'd like to stream video+audio (different qualities : ~1000 kbps and ~400 kbps) and audio only for low-bandwidth (~128 kbps).
Adobe Flash Media Encoder Live allows me to stream different qualities. And what about audio-only stream?
And of course I don't want just to hide video on client-side.
I am using Flash Media server 4.5 and i read the tutorial if i want to stream the live feed, i may need to use the media live encoder.
but what i found in media encoder is i have to manually setup everything and it only support camera devices. But in my case i have multiple video files keep received from another program and place it on file system (server),my goal is use the Flash Media server to perform a live boardcasting with these video file one by one. That means when client watching a live streaming, they will not notice the server is playing mov1, then mov2, then mov3, then mov4... and so on.
You can imagine i am trying to boardcast a live footage say for 60sec, but the video file will not recorded entirely after 60sec, instead for every 10sec i will save a new video file, so that when client watching the live by HLS [URL]when the time reach to 10sec, a mov1 video file available and FMS should boardcast this video on live123.when the time reach to 20sec, a mov2 video file available and FMS should Immediately follow the mov1 boardcast on live123.and so on...Also can FMS dynamically create a new streaming session (invoke by code), so that when client A uploading some video files to the server, the FMS open a new streaming session only stream cilent A video files?the configuration to boardcasting like screen size, bit rate, etc should be pre-defined on the server.

I'm interested in setting up a site where I can put MP3 files on my server (outside the web root) and stream them to a flash application. I'm not talking about progressive download here. The basic idea is to let visitors hear a band's music without actually downloading or caching an mp3 or SWF which could be located as a file and saved or ripped.I have seen this awesome tutorial on streaming an flv and was wondering
View 2 RepliesI have started a stream from Flash media encoder to flash media server. According to my encoder, it should be located at: "rtmp://localhost/live" and is called livestream.In the Flash software I try and set the source of FLVPlayback component to rtmp://localhost/live/livestream", and I get this error: "NetStream.Play.StreamNotFound : Adobe Flash tried to play a live or recorded stream that does not exist.

View 9 RepliesI'm trying to stream an audio clip via rtmp in as2. I'm not particularly attached to the method, but this is the starting point I am at below:
Code:
var s:Sound = new Sound();
var req:String = "rtmp://path/filename"; //doesn't work
var req:String = "[URL]"; //This works
s.loadSound(req, true);
I need to get an RTMP audio stream working, does anyone have any experience with this? (Also not sure if this goes in the actionscript folder or the sounds folder.
I used source code I found for a sound stream visualization (By Peter Dehaan). I added a play and stop button, but when a user clicks on play more then once it loads the stream multiple times. I don't quite know what I should do to prevent this.
