goal is to record a stream from a webcam with the best possible quality regardless the bandwith of the user.(it doesn't have to be live or broadcast, just stored on the server)
is it best to record from server side with asc script or directly from the flash player ?what are the parameters on the server that i can play with in order to cache locally the stream if the bandwith is not high enough ?
I'm currently working on a webcam recorder to record high quality video. I had the recorder working before, but the video quality was quite poor. Instead I'm trying to use a client side buffer and then upload the buffer after recording has stopped. I thought after I unattached the video and audio from the NetStream that either a NetStream.Buffer.Empty or NetStream.Record.Stop event would be sent when the buffer was finished uploading.
What is actually happening after I start recording is two NetStream.Record.Stop events are being sent in a row, so recording never really happens. Also, on the server side I'm trying to save a user name and password into a variable, but I'm not sure how to go about doing that since the application script is just a bunch of callback functions.
Am trying to record video from my webcam.
here is my code
[code]...
When i click record_btn, flash asks me permission to access my webcam. If i alow in the screen i am able to see live video. But I want to store the video and replay it.
My company is about to launch an online teaching product allowing users to use a webcam to record themselves giving a presentation. That presentation can then be submitted to a supervisor to review and comment on. While making their recordings, users can record multiple attempts and review each immediately after stopping the recording. All of this is being done with a browser based Flash application connecting to an instance of FMS 3.5.
All of this is working well. However, we recently found out that due to some of our other products, we are getting hammered with fees based on the amount of bandwidth we are using in our data center. We have made some alterations to curtail these problems, but we are concerned that this new product is going to push us over the edge again. Our original plan was to keep the video stream right around 115 kbps, a relatively low data rate. But when thinking about the expected concurrent users, the bandwidth starts to stack up and really spike.
So we are now looking for ways to limit the bandwidth that this new product will use. One idea was to figure out how to record the video locally when users where recording their test presentations. I thought that was now possible, but apparently that is not yet the case with the Flash Player.
Another idea was to limit the bandwidth that is allocated to each user that connects to our FMS. We are hoping to address the spiking issue with this limitation. I am, however, concerned about what will happen to a video stream that is getting squeezed on the server site. I know when users have limited bandwidth, video files that are published to the FMS are compromised (poor quality). But what happens when the bandwidth is limited on the server side? Do the same things happen to the published video file? Or can the server somehow queue up the data coming in and deal with it in full when it finally gets to it. My guess is that this is not the case, but was curious what others though.
We've purchased the FMS 4.5 and are now planning an application that lets users record a video to the server using their webcam. Straight forward, if we were to stream only to a flash video object. BUT, we would like our padders to be able to see the videos on demand too. Can't find a tutorial on this, seems like everyone's more interested in live streams.The server is able to record a stream in mp4, but when I'm testing these files in Adobe Media Player it won't play :| What codec is used, and is it possible to play this format on an iPad? If not, is there som sort of solution other than manually transcode to the right format.
View 5 RepliesWe want to build an application that allows the user to record a video using their webcam on our site using flash and save the URL in a database using PHP. So that we can allow the user to send the video's to other users etc. Also we want to offer the user the possibility to upload their movies (per mail and with PHP) and convert them to flash movies, can this also be done using Flash media server? (maybe in combination with AMFPHP)
View 2 RepliesI develop failover fms application with server-side action script. But i have a problem that FMS can't continue to record stream with record mode "append".
Environment: FMS 4.5.1 r484 on CentOS 5.5/6.0
Goals:
I have 2 same data streams in failover application and republish primary to livepkgr application.
I have to store of last 10 hours intact recorded video (DVR).
Failover app logic:
1. I create NetConnection and NetStream to livepackager;
2. When primary stream is connected it attach the primary stream to livePackager NetStream
3. If primary stream is disconnected it reattach the backup stream to livePackager NetStream
Problem: I have testing environment. It stop primary stream every 5 min, and started primary stream 5 min after stopping.
It work's, fine, but after a few hours testing LIVEPACKAGER falls. It can't record a stream, NetStream.Record.Start -> NetStream.Record.NoAccess -> NetStream.Record.Stop
Search a solution: I try to relaunch recording process and have no success. try to shutdown/start livepackager, it's same, try to restart server, same no success.
I cant stream.clear() or record with mode "record" cause it clears my dvr cache, I cant clean stream directory in livepackager application.

Can I send/publish MP4/H.264 video (live or record) to FMS from webcam? Another similar question; does Flash (10?) support H.264 encoder?
View 3 RepliesI'm trying to record a stream from a webcam using FMS4 developer edition. The streams are recording on a linux box in .flv files. These files though have problems.
1 - The video quality is terrible. Fuzzy/blocky. Any kind of motion looks awful. Is there any way to improve this?
2 - The sound jumps/skips and goes out of time with the video.
As it is now this is useless. I am trying to make a system where a user records a short video from the camera and then I upload it to YouTube from my server. If you use Youtube's webcam page the video quality is quite acceptable and the audio is obviously in sync too, so they must know something I don't. [URL]..
this may be really dumb question, but I haven't figured it out. Is it possible to stream to ustream with lets say 300 bitrate and record 1000 bitrate video to computer

I call
[Code]...
However, when I look at the FMS Admin Console at the streams in app/_definst_, their types are either "NetStream" or "Live". If they were being saved wouldn't they say "Stored"? After I close the application doing the recording, the "NetStream" type stream disappears, and after a while all the "Live" typed streams are gone too. Nothing is saved.
I have no idea what is happening. I don't know if it's a problem with my AS3 code not closing the recording properly or if I'm doing something else wrong, or maybe somethgin isn't right in the FMS?
I wonder if i can do the following, send a stream to fms from a webcam and then serve it with apache on http x-flv format.

View 2 RepliesI have seen lots of different things about recording live streams (maybe too much, pieces everywhere but no one good source for the answers), but not what I am looking for...I want to setup recording of live streams on FMIS 3.5 where the file is named the stream name plus a timestamp (something like streamname-yyyymmddHHMMSS: myteststream-20090928101015).The people who use our site tend to start/stop several times (we are dealing with events that have breaks) and I want to be able to combine all the files with the same name into one big file on the server side afterwards using some utilities.I cannot find a tutorial that walks you through the different functions, the differences between them, and how recording is setup/works.
View 3 RepliesI see FMS has the ability to record live streams. I've done it and it works nicely.
Ideally I'd like people to watch my event live AND archive it while they watch.
It's natural for users to find something interesting and record it when subscribing to a live video,
but so far I can only record it when publishing,
So I have FMLE and FMS. to record and stream video at the same time.
On server side I have "main"
application.onPublish = function(client, potok){
potok.onStatus = function(info){
for(var i in info){
trace(i + "=" + info[i]);

I'm looking for a solution where clients watch a live stream video and can record part of this stream while watching and save this recording to disk. I can think of several solutions but not sure if any of them is possible:
- The selected part is recorded locally and saved through FileRefence.
- The selected part is recorded with FMS though a second NetStream and saved with a unique ID. The user can retrieve the recorded video by download.
- Start-time and end-time of the recording are send to the server where some script extracts the requested video from the live stream recording file and return it as a download.
How to record a live video stream playing on an FLVPlayback?
View 1 RepliesServer conf:
2 x Intel(R) Xeon(R) CPU L5410 @ 2.33GHz
16Gb RAM
2 Gbit ethernet channel
OS - Linux CentOS 5.5 x86_64
FMS4 Interactive
Live stream parameters:
320Ń…240 qua_=87 bw_=200000 kf_=5 fps_=18
So, after approximately 600 connections to one stream video becomes choppy (periodically freeze, slow motions). CPU-usage at this time is 100-120% (maximum is 800%, 100% per each core), network usage is 500 Mbit/sec.But second live stream(with few connections) at this server looks fine simultaneously with 600 connections at first stream.Experiments with recommendation in "Configuring performance features" documentation chapter(enabling/disabling aggregate messages and configure the size of stream chunks) do not help.
So far , I only found tutorials on control these attributes while publishing the stream
