Record and Streaming playback

Hi guys I am a newbie to FMS, got excited about it when I heard that Amazon cloud services are now including FMS for a marginal increase in cost.
So all I am looking to do is:
1) Record off a web cam and store the video using FMS
2) Play the video stream using FMS.
If someone could point the way to some sample code, then I will be off an running.
Thanks a bunch.

Go through FMS documentation - it should have simple code snippets for you to get started off.

Buzz on audio when recording and in playback - new mini mac?

Up until now I have been recording on a Macbook Pro, however I have recently moved onto a Mac Mini and that's when this problem started...
I am having trouble because when I play audio and the R button is on theres a high fuzz/ buzz/ ringing sound along with what I am playing. This is recorded and I can hear it when I listen back too. What's weird is that there's a dead silence between the notes. When recording software instruments through a usb midi keyboard it works and playback as it should.
I have tried changing the usb input of my sound card, using different instruments incase it's a buzz from that, changing the leads, and also checked the sound card still works fine with my old Macbook Pro. All this is fine. (I use an Alesis IO4 sound card)
All I can think is theres something I don't understand that I haven't done properly in Logic since installing it on the Mac Mini which differs to how it is set up on the macbook. That, or something is wrong with the Mac Mini itself however it's brand new from Apple.
Please help if you can shed any light on this.
I hope this makes some sense!

I would suggest providing an audio sample of the "fuzz/buzz/ringing sound" so that people can better guess what the problem is.
Noise comes from many places, and there are many types of noise.
Hard to take a shot in the dark otherwise.

Recording and Streaming?

I'd like to record some DJ sessions and live concerts. Can you run a line in into the iPad (from the output of a mixer)? So far the apps I've seen only record from the built in mic. Also is there an app that let's you stream recordings live or at all for that matter?

Ok... This may work for you. You need these three components:
Griffin iMic USB Audio Interface
http://store.apple.com/us/product/TX532ZM/A?mco=MTY3ODQ5OTY
Apple iPad Camera Connection Kit
http://store.apple.com/us/product/MC531ZM/A?fnode=MTc0MjU4NjE&mco=MTc0Njk4NzU
Audio Cable
1/8 in./3.5mm
This is how I set it up to test if this would work, it does. Connect the USB Camera connecter to the iPad. Plug the Griffin iMic USB Audio Interface into the USB Camera Connecter. Plug a 1/8 audio into the Griffin iMic USB Audio Interface and the other end into an iPad nano... I used Memo Recorder free from the app store to record the audio..... Works no problem.
You might have to use a 1/8 audio with RCA on the other end, depending on the output connecter that is on the mixer.

JFM recording and streaming at the same time

Hello Everyone,
I was hoping someone could help me with using a webcam device for sending and recording at the same time.
At this moment I'm only able to record. I tried to make another processor, and put the input of the streaming processor
to the one that is recording, but problem is the streaming processor outputs not a streaming format. If I could stream
with RTP I could embed a player in a website and view from there, while recording at the same time.
Could somebody explain to me what do to here, or provide me a snippet of code, I really need this to work.
I created this code, but this only records.
import java.io.IOException;
import javax.media.*;
import javax.media.format.*;
import javax.media.protocol.*;
public class Record {
     public Processor createProcessor(){
          Format formats[] = new Format[2];
          formats[0] = new AudioFormat(AudioFormat.IMA4);//IMA4
          formats[1] = new VideoFormat(VideoFormat.CINEPAK);//CINEPAK
          FileTypeDescriptor outputType = new FileTypeDescriptor(FileTypeDescriptor.QUICKTIME);
          Processor p = null;
          try {
               p = Manager.createRealizedProcessor(new ProcessorModel(formats,outputType));
               } catch (IOException e) {
                    System.out.println("Error! 1");
               System.exit(-1);
               } catch (NoProcessorException e) {
                    System.out.println("Error! 2");
               System.exit(-1);
               } catch (CannotRealizeException e) {
                    System.out.println("Error! 3");
               System.exit(-1);
          return p;
     public static void main(String [] args) {
          Record record = new Record();
          Processor p = record.createProcessor();
          DataSink sink;
          MediaLocator dest = new MediaLocator("file://newfile.mpeg");
          try{
               sink = Manager.createDataSink(p.getDataOutput(), dest);
               sink.open();
               p.start();
               sink.start();
               try {
               Thread.currentThread().sleep(6000);
               } catch (InterruptedException ie) {
               p.stop();
               p.close();
               Thread.currentThread().sleep(6000);
               sink.close();
          } catch (Exception exception) {
               System.out.println("error!");
          System.out.println("finished");
Kind regards,

Take a look at the following example. It demonstrates how to do 2 things with the same input (namely view and record)

Pause FMR recording and video playback capture not working??

Hello!
I'm trying to record full motion recording in CAPTIVATE, but the PAUSE feature looks like it is not working for me. I even tried to modify the shortcut key, but nothing works. Anybody else have this trouble or am I missing something obvius here?? I thought that maybe the FMR mode cannot be PAUSED, but nothing on that matter can be found in the manual.
Also, I'm trying to produce e-learning content for PREMIERE and SOUNDBOOTH. I've noticed that video playback within PREMIERE is not captured by CAPTIVATE. I've seen on the forum that others had this issue. Is version 5 of captivate behaving the same? Is it still not possible to capture onscreen video playback?
Any info here would be greatly appreciated.
Thanks!

I'm having the same problem where Captivate 5 in FMR doesn't respond to the Pause key, however I'm noticing that there hasn't been a solution supplied here.
Is there another location/forum where Adobe representatives for Captivate are actively monitoring questions and problems for this product?

Audio drops mid recording and/or playback

I recorded a video on my 3gs phone last night and it isn't that long, maybe 4 minutes in length. I was able to upload to my computer and when I went to play it back the audio drops halfway through. I checked on my iPhone and the audio drops out there as well. Anyone know why or how this happened that when I'm recording something the audio just stopped being recorded while the video was still recording?

Recording and Sound Playback

I have made video clips in both Photobooth and Quicktime but cannot hear the audio on playback. I check the sound settings and midi settings and even did a PRAM set but no sound play on clips that I create

I have a movie on disk in mpeg. So I bought the upgrade for Quicktime, QuickTime MPEG-2 Playback Component for Mac OS.
I am able to play the movie on imovie but there is no sound. Have you any ideas as to how to fix it?
Regards,
Deb.

DAQ Record and Playback

I have a PCI-6534 DAQ card in a PC and I am trying to record and then playback some motor encoder signals. I used DAQAssistant to create the code and then I have tried to modularize it a bit. I'm guessing I broke something, but I am not sure what.
My problem is that the playback refuses to work and gives me various errors depending on which "lines" parameter I pass in. The lines parameter I use is the same on the recording functions and the playback.
I started by first trying to record on Dev1/port0/lines0:2. Recording worked fine and it produced the required datafile. When I go to play back the file, I get the message
Partial use of physical lines within a physical port is not supported by this device, given the requested Sample Timing Type.
Consider specifying the entire port and tristating the lines you do not want driven.
Property: SampTimingType
Requested Value: Sample Clock
So then I go back and record on Dev1/port0. Again it records fine, but on playback with the same device, I get...
Requested creation of a separate channel for each line is not possible when a digital port is specified as the physical channel.
Specify a range of digital lines, such as "Dev1/port0/line0:7", as the physical channel.
Physical Channel Name: Dev1/port0
HoKay, so I go back again and record on "Dev1/port0/line0:7". Again it records fine and on playback I get...
When writing, supply data for all channels in the task. Alternatively, modify the task to contain the same number of channels as the data written.
Number of Channels in Task: 8
Number of Channels in Data: 1
I am at a loss as to why I can record so easily, but playbacks are a b***h. Help!
Attached are my VI's that I am using.

I think I figured it out.
When I created the DAQ VIs using DAQAssistant, I did so by selecting individual lines. When I changed things around to get playback to work, I simply changed the text field going into the lines to be "Dev1/port0". I could never get this to work.
I went back and regenerated the playback VIs using DAQAssistant, this time specifying a port output (instead of lines). This time it read and played the data fine.
The moral is that if you use DAQAssistant to generate VIs, be very careful when you change the parameters on those VIs.
Attached is my new test program which works well.

Recording beta question - seeking in recorded streams and syncing playback

hi lccs, some initial questions for you as i get started on the beta..
you say audio and video are saved in separate FLVs on the client server. does LCCS ensure that audio/video sync is maintained during playback?
how are the recorded streams delivered during playback? can you seek into these streams? e.g. if i have a recording of a video chat, can i use a timeline to seek forward and back through that video?
and finally - i will want to play back a recorded audio video chat between two users. will LCCS take care of synchronization between these four streams? (two video, two audio) or do i need to build a synchronized buffering strategy to achieve this?

To reiterate Raff's point - when you setup a ConnectSessionContainer with a
PlaybackAuthenticator (essentially, a "playback application"), that
ConnectSession does all the work of synchronizing streams for you. As Raff
says, you can build a timeline and seek within it - ConnectSession's
archiveManager exposes all aspects of the playback to you.
In fact, here's a basic seek bar you could try :
<s:HSlider width="800" maximum="{cSession.archiveManager.totalTime}"
value="{cSession.archiveManager.currentTime}" id="slider"
change="cSession.archiveManager.seek(slider.value)"/>
lastly, as Raff also says, you're not restricted to playing back the exact
application you recorded. If you had, say, audio/video chat plus text chat
recorded, and all you wanted for playback was the A/V, remove the text chat
from your playback application (and delete the chat FLV from the recording
zip, to save on bandwidth), and your playback app should just work. You can
also totally re-layout how your app looks for playback as compared to
"live", or allow your users to manipulate the layout or contents of what's
being played back as they watch the recording. We think this will allow for
some really interesting, innovative applications.
hope that helps,
nigel

How do I make a quality recording of streaming music (and get into iTunes)?

I'd like to make a recording of some streaming music. I called Apple Care and the agent suggested using Quick Time. Yes, I can make an audio recording, but it included a lot of background noise. (I could even hear myself tapping on my computer when I listened to the playback.) Next, I tried using Soundflower because in the "Internal Audio"section of this page, I got the impression that I wouldn't be using my "live" mic on my MacBook Air, but it did. Again, I could hear background noise.
Is there a way to make a better recording of streamed music from the internet...without being a technical wiz? I am not. Thanks for your help!

If you do a general web search you will find multiple answers. iTunes does not do what you want to do, nor any Apple software as far as I am aware. Possibly what you are doing is strictly speaking skirting legality (if the stream producer doesn't simply make a simple way to download) which makes providing an answer on Apple's forum (where according to terms of use we have to remain legal) complicated.

How to record and playback waveform?

Hi,
I would like to record the waveform of my signal and then playback again for analysis purposes.
My current VI can read the signals from 2 channels of my oscilloscope (as shown in the picture) using the waveform chart. How and what should I include in my VI so that I can playback the signal waveform so that I can trace back the place where I previously could not stop the signal in time to obtain the result i want?
Also, is my cross correlation connected properly in the VI? Because while running the signal, this is the waveform I got from the above 2channels waveform (which I think its wrong).
Thanks for much! Your help is greatly appreciated! =)

Acquire Multiple Waveforms(crosscorrelation).vi ‏77 KB

To record (or to save) the acquired data on to disk use the TDMS vi's placed in Files I/O-> TDM streaming..
There will be some example shipped along with the LV on how to use this files.
So once all the data have been stored to the disk read them back (u have to create another vi for reading them) and populate the same to the w/f chart (read small chunks of data = the sampling rate , so that you can exactly play back the data when u were acquiring. This also will not hog your CPU if the data stored is huge)

Record and Playback performance goes down at high frequency

Hi,
We're testing record and playback using USRP-2920( LV 2013sp1, NI-USRP 14)
To test it, we downloaded record and playback example code.
Signal source is a function generator outputting 6 MHz bandwidth 8 VSB modulation signal.
USRP Rx parameters are center = variant / gain = 0 / IQ rate = 25MHz and Tx parameters are center = same as Rx center / gain = 0 / IQ rate = 25MHz
The problem is... in low carrier frequency like 70MHz, quality of playback signal is great.
But in high carrier freqency like 2.2GHz, SNR and signal power dropped significantly i.e. they tend to drop as carrier frequency goes high.
And the strange thing is as carrier frequency is increased, a small peak on the center is increased as well.
Please check the attatched file to see the tendancy.
So.. my question is why is this tendancy occures?(we tested another USRP and the result was same as before)
and what should we do to reduce this effect?
Regards,
Youngmin

record and playback results.xls ‏469 KB

Hi,
I suggest a couple of things:
NI USRP 2920 is a non-calibrated device. So setting a gain value of 0 at different frequencies could mean a different actual gain. So try increasing the Rx recording gain (on the USRP) in cases where you observe low SNR. Similarly Tx is not calibrated.
Is the signal recording done with cables or over wireless medium ? You can try to eliminate any spurious signals if you use SMA cables while recording.
I think the power at the center of the spectrum is the DC offset. You may refer to the DC Offset/LO leakage section in the best practices section here http://www.ni.com/white-paper/13881/en/
Thanks.

Recording a stream and using it on the fly

Hi,
I'm trying to upload a video stream from a flash client and
convert the video stream on the fly (from an external converter
like ffmpeg or vlc).
Since I don't manage to send the stream directly to the
converter, a solution I have found is to publish the sream as
"record", and have a converter read the file to perform the
operation.
However, when setting the record method for publishing, the
recorded file is not written continuously. Incoming stream is
buffered, written, buffered, written and so on. So, the program
reading the file stops it reaches the end.
Is there a way in FMS2 to either:
- forward incoming RTMP stream to a stream converter (using
an outgoing RTSP stream or something like that) ?
- force FMS2 to dump the stream continuously, as soon as it
receives the incoming data ?
Thanks for any help,
Greg

Stream.syncWrite
Availability Flash Media Server 2.
Usage myStream.syncWrite
Description
Property; a Boolean value that controls when a stream writes
the contents of the buffer to a
FLV file when the stream is recording. When syncWrite is
true, all the messages that pass
through the stream are flushed to the FLV file immediately.
It is highly recommended that
user should only set syncWrite to true in a stream that
contains only data. Synchronization
problems might occur when syncWrite is set to true in a
stream that contains data and
audio, video, or both.
... sounds like a problem is occuring :)

I can't get my vocals to record and playback!

The sound bars move and I can hear myself on my speakers but my voice doesn't record or playback. I'm micing directly in to my computer. My midi keyboard plays and records and plays back. I have it set to vocals and male R&B, monitor on.

Did you figure this out? I am a first time user. I have a mic, plugged in to my mac and I'm trying to lay vocal tracks...can you help me?
