I am using Adobe Citrus and Air. The goal is to make a voice chat application with low latency. I take the sound samples that I get from the Microphone SAMPLE_DATA_EVENT encode them in using Native Process and speexenc.exe.
The question with method should I use for the sending of the samples. I tried object repication and the latency is to big.
We are building a live RTMFP voice chat application with Cumulus. While the basic voice transfer works pretty easy using NetStreams, we have one big problem:There does not seem to be a way to manipulate the microphone data that the NetStream sends, and also not a way to manipulate the data the listening NetStream receives before it is played.However, this is exactly what we need. We do not want to transfer the normal microphone recorded audio, but first pitch it, then send it, then play it. Or first send it, then pitch it, then play it. But it seems that the whole audio recording, speex encoding, speex decoding and audio playback is completely encapsuled within the NetStream class.The only ways to achieve what we want (and all of them removing NetStream completely) seem to be:Send raw pitched audio data. That does work, but is of course a lot of data to send and will likely not work fast enough outside of our local LAN testing.
Pitch audio data, convert to ogg/mp3 using existing encoders for flash, send, decode ogg/mp3 and play. But this would mean encoding each and every sample packet that is received from the microphone, adding header stuff, etc. So this would likely not even yield that much of a benefit compared to raw audio data.2.1. This would actually be a good way if there was a Speex encoder/decoder for flash. But ironically, there is none other than the built in one (which is used for encoding/decoding audio in NetStreams) that cannot be explicitly used. ot offering it, Adobe...Send the data to the Cumulus server, pitch (and probably convert) there and send to the recipient. This would likely not even be that much faster than 1. and also throw away the exact benefit of RTMFP, P2P communication.
Its just a quick question: Is it possible to run a falsh based voice chat without using the flash media server and instead using some kind of peer to peer connection? (just one to one connection, one to many connections are not needed)

View 1 RepliesI am building an enterprise application which involves many to many video chat. Most of the chats at any given time will be idle but they still need to trasmit some frames to keep the video chat alive and let other person know that someone is available. Will I be able to achieve this without any media server such as FMS and wowza? I heard about data packet loss during RTMFP. Is that true? What would be my limitations?
View 1 RepliesI have created a video chat room by FMS/Flex. what I need to do is:
If everybody in one chat room can use rtmfp, we go with rtmfp if anybody in the chat room disabled his rtmfp, we go with rtmp.
Now I need to create a logic to decide if everybody can use rtmfp between each other, Is there a good way to do so?
I will create a voice chat application with Adobe Flex and I want use the opensource Red5 as a server.But, I confuse how to start it. it's possible just use NetStream and NetConnection?

View 1 RepliesI am testing RTMFP unicast for a video chat project using FM Developer Server 4.0.During the testing I overloaded the upload traffic to make packets dropped rather than suffering delay due to retransmission.
However, I see it makes a significant delay and it looks like doing retransmission just like RTMP.
Do you know if there is an option in FMS to disable the retransmission or other configuration I have to consider?One thing I found is "Netstream.videoReliable=false; Netstream.audioReliable=false;" but it doesn't make any difference.
Is there an open source implementation of rtmfp?Is there FMS hosting that support rtmfp?

View 3 Repliesi want to create a chat app using flex 4.5 mobile project for android device. For the chat screen, i wanted it to look glossy and stylish. Hence i thought i would use the list component and disable the selection in it. I m able to add the chat messages into the list. But i doubt if large chat data might hinder the performance. Im using a collection and i ve binded it with the list. Whenever i receive a chat i update the collection and it gets displayed in the list. Can someone tell me if his could pose a performance problem as list component is not intended for this purpose.
View 1 RepliesHow to do voice recording using flash action script 8 with example.
View 1 RepliesI am developing an application where I need to record voice(for those who does not have a webcam so they can use only microphone to record voice) or video(those who have a a webcam - like laptop or external) files and save them on server, thereafter save the file name and logged in users id on database for later access.
I know I need to use some sort of flash app for this. But is there any free one which could server this purpose or even if there are paid ones which could serve this purpose that would be great. I tried google but may be I was not being able to go after the proper term or something, I could not succeed finding a proper solution for this.
is that possible that flash can develop voice recognition application? if user says "A" then flash can call movieclip "A", or in the application e-learning, user just say "next" then the application going to the next page.

View 3 RepliesOk so from all my research I'm fairly positive P2P is not possible in Silverlight 4 (in browser). Flash can do P2P using Stratus/RTMFP which I believe uses UDP hole punching and a Stratus server to initialize the connection. Is there any plans for Microsoft to add some kind of p2p rendezvous service in the future? Can we get a definitive yes/no on whether or not p2p is possible in SL4.

View 4 RepliesI'm looking for a flash widget that allows users to record their audio and then send it to the server.
There are a few similar questions:
Record Audio and Upload as Wav or MP3 to server
They advocate using Red5 or flash media server.
Shouldn't it be possible to record locally on the user's client using the codecs that the user already has and then upload the resulting file to the server, rather than say, process the and record the stream on the server itself.
I'm going to do a voice recording plugin/addon on a website that will record audio and send it to the server for further processing. I have had two suggestions; either write a java applet or use flash. The service is supposed to work for all major browsers(IE, Firefox, chrome,..). I'm new to this area of development and is looking for tips on how to proceed with this. What is the pro's and con's for each solution?
For java applet, what Java speech API library do you recommend? I want a simple, small library, I only need voice input. Also, I am puzzled by Flash development, I can't find any good information about development, the adobe website dosn't make much sense. What is the programming language for flash, and how do you actually run it in html code? I have found ActionScript 3, is that used to create Flash plugins and can it perform voice recording?
I see that the new Flash Media Servers were released. Looking over the information on the product pages, Flash Media Enterprise Server 4 is the only available product that supports RTMFP connections?
We currently have Flash Media Server 3.5 and our product utilizes RTMP connections, but I've been working with your Stratus Server and RTMFP and have found that the new protocol better fits our needs. However, the price for Flash Media Enterprise Server 4 is beyond our budget. Is there any possibility that RTMFP support are/will be available in the lower levels of Flash Media Server?
I need to create a simple video streaming without using Flash comunicator server or other streaming server.So I am thinking to use RTMFP but I haven' t found any good RTMFP tutorial for this issue.
Do you know tutorial for Video Streaming using RTMFP ?
Only the Flash Media Enterprise Server(FMES) has the "RTMFP peer introduction services" [URL] influxis created SmartMesh which enables p2p in Flash Media Interactive Server(FMiS). [URL] I couldn't find info on what does the peer introduction service do, what is the difference in capabilities of FMiS and FMES and what is the difference between RTMFP unicast and RMTFP multicast. Is it possible to create a p2p rtmfp connection between two clients with FMiS assuming I have a webservice that help clients exchange FarID?
View 1 RepliesI use RTMFP with NetGroup and Adobe Cirrus. Broadcasting settings are 320x240 with 5 fps.
However, in some cases it takes a long time for the webcam stream to appear (10-20 seconds, even if having a 1:1 connection). If the stream appears eventually, it looks like this:
I think this comes from a high keyframe interval and the subscribers needs to wait for the next keyframe, so that the stream appears properly. This happens in contrast to streaming servers, where the server caches the last keyframes from the publisher stream.
how I am able to tune the broadcasting, e.g. set the keyframe interval and other settings. Can you recommend a good setup? And, why is this issue not popular (I haven't found much information about it)?
