I'm using flash media server and trying to record the stream but having a problem as I've outlined below. Thanks for taking the time to read this post.
How do I detach my camera from one stream and attach it to a new stream? What I'm trying to do is record the camera stream for 10 seconds and then play it live on a different stream..I try to netstream.close and then netstream.attachCamera(cam0) but it won't let me attach it to the second new stream. What's wrong?
You dont have to close the stream. You can use the attachCamera method with a null argument.
netstream.attachCamera(null);

I'm streaming data from a server and passing it into a net stream in data generation mode. I'm successfully wrapping H264 and PCMU to be played back through NetStream, however I need to be able to capture this output from the video display it's on and store it in an image. When using an RTMP server, I'd configure it to send an RtmpSampleAccess command, with true,true for audio and video access allowed. When using RTMFP I'd do the same, send() a RtmpSampleAccess true,true from the peer to allow access.
I believe I need to send in an FLV tag for a script data object to represent the RtmpSampleAccess command, however I can't find any information on what the format of that tag needs to be. I've tried using the OSMF FLVTagScriptDataObject with the objects set to the following combinations:
["|RtmpSampleAccess", true, true];
["|RtmpSampleAccess", [true, true]];
And various attempts at guessing the naming for object parameters (though looking at the protocol docs, I'm not sure there is one).
Could someone out there help me here, would be much appreciated.
Where you put your Netstream into Data Generation mode you add a second Play command. The second one simply plays "a blank" and for some reason this overrides the security error.
ns.play(null);
ns.play(""); //works to avoid all security errors
ns.appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN);
Then to draw just setup a button to run the draw_VideoFrame function when clicked, or try real-time drawing with something like below (using enterFrame):
vid_Obj.addEventListener(Event.ENTER_FRAME, draw_VideoFrame);
and then create a function like this example.
function draw_VideoFrame (e:Event) : void
{
vid_BMD.draw( vid_Obj ); //draw into a BitMapData variable
}
I got a problem with RED5 in combination with Flash. For a personal project i am trying to make a Skype-like application. I already got a application that records the users webcam and saves it with a custom filename on the RED5 server.
But i am stuck trying to connect one more user to that window for a video chat. I made a new video container in Flash but i don't know how to connect a second client to the same stream in AS3 with Red5?
I searched on the net but i only get really old threads about RED5 in combination with Flex.
Maybe this is helping understanding my problem?
Could someone help me out? Or get me in the right direction?
Video chat? You will need 2 streams, for every client. Inbound and outbound. Outbound is a stream from the client to the media server, inbound is consumed stream of another user. So it will look like:
_streamOut = new NetStream(connection, NetStream.CONNECT_TO_FMS);
_streamIn = new NetStream(connection, NetStream.CONNECT_TO_FMS);
_streamOut.addEventListener(NetStatusEvent.NET_STATUS, onStreamOutNetStatus);
_streamIn.addEventListener(NetStatusEvent.NET_STATUS, onStreamInNetStatus);
_streamOut.attachAudio(microphone);
_streamOut.attachCamera(camera);
_streamOut.publish(hostPeerID);
_streamIn.play(companionPeerID);
Also there are some helpful examples, did you check them?
I'm trying to add video recording into a mobile app I'm building. But am struggling with the recording part. So far I have got the camera class displaying in a video object with the code below.
private function init():void
{
var camera1:Camera = Camera.getCamera();
trace(Camera.names);
if (camera1)
{
var ui1:UIComponent = new UIComponent();
var video:Video = new Video (320, 240);
camera1.setMode(320, 240, 24);
camera1.setQuality(0, 100);
video.attachCamera(camera1);
ui1.addChild(video);
cameraGroup1.addElement(ui1);
}
}
From what I understand you can use the cameraUI class instead to achieve the recording part and add it to the library but it would mean using the default camera application when I would rather use my own. I imagine recording using the camera class would require a tick to grab each frame and then something like the videoFrame event but could really use some code or a point in the right direction.
Thanks in advance.
Best way to record using the Flash or AIR application is Media Server. You can connect your application with Media Server (Flash Media Server / Red5 / any other Media Server which is providing Media Recording and Publishing.) and publish your stream for recording.
Second way, I need to search out the code but logically I can say answer. We need to convert Camera stream buffer in to the binary data and we need to save binary data as video file o File system.
For that you can write down some code in ActionScript and need to write down some code in the Native Application as Native Extension.
I've been playing around with node and websockets and built a small test app that streams audio using websockets. The server breaks apart the mp3 using createReadStream, throttles the stream using node-throttle and sens the binary data using the "ws" module.
On the client side I pick up the chunks on the websocket and use decodeAudioData (http://www.html5rocks.com/en/tutorials/webaudio/intro/) to decode and play the chunk. It all works relatively ok.
What I was curious to do next was to stream video in the same manner to the HTML5 video tag. But I can't really find any reference material on the web to achieve this in the same manner as my audio test above.
Is there a video equivalent for "decodeAudioData"?
Can I feed chunks of data into a video tag?
I've got a similar sample running that I picked up from...
https://gist.github.com/paolorossi/1993068
But this isn't really what I am looking for. First of all it doesn't really seem to be streaming to me. The client buffers it all before playing it.
Also, similar to my audio test I want the stream to be throttled on the server side so that when a new client connects they join the video at whatever point it is currently at. i.e. 30 minutes in or whatever.
Thanks
OK,
I found a solution to this after much searching.
The MediaSource API is what I was looking for...
var mediaSource = new MediaSource();
var sourceBuffer = mediaSource.addSourceBuffer('video/webm; codecs="vorbis,vp8"');
sourceBuffer.append(new Uint8Array(data));
This link provided the solution...

I am testing sound recording in as3 and now i have this question :
I am using this line to start the recording and write sound data to the bytearray (wich works) :
_mic.addEventListener(SampleDataEvent.SAMPLE_DATA, getMicAudio);
But the thing is that the sound only start to get written when there is some activity on the mic...
For example, let say i use a "rec" button and click it, i want the bytearray to be filled as soon as the button is clicked...not waiting for mic activity...
So, is it possible to fill a bytearray with "no sound" and how would that be done?
Thanks for any help you can bring!
Just adjust the microphone settings so that there is ALWAYS activity on it as long as you're running it. You do this by adjusting settings like microphone.silenceLevel:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/media/Microphone.html#setSilenceLevel()
So for example, you set the silence level to 0 and the timeout to 99999 or something. This way flash will no longer automatically shut off the microphone when there is no or low sound.
