Capture and transmit audio

Hi all,
I need to implement an applet wich can capture audio (and possibly video) from the client for transmit it to the server. Is there some example already developed? Where I can found info about this?
Thanks a lot for your help!
Dmitry Yeskin.

If your code works, please send it to me!!!!
I have many problems with given sources: nothing works normally!!!
Thanks,

  • Capture and transmit live media

    I am doing a project that capture live media from a capture device and transmit it to a client. Currently I can capture and transmit, but the problem is when I start transmit, the local player stops playing. If I clone datasource and use the cloned datasource for transmitting, the local player does not stop after it starts transmitting, but the remote site can't receive any stream. In short, my problem is I can't make the local and remote sites play captured media simultaniously. I tried JM Studio and it works, but I can't understand how they implement it. It seems that they didn't use cloned datasource. Anyone who have this kind of experience please help me. Thanks a lot.

    If you want to display video while transmiting it you can use the MonitorControl. Consult the jmf guide and solutions or this same forum.
    But MonitorControl can be a complex solution, specially if you want to monitor video+audio.
    You can also use clones. You need undestand that the clones depend of its original datasource, so this origin have to be connected to the clone works. Consult google or this same forum to more info.

  • Capture and streaming audio and video

    JavaFX supports capture and record audio and video and need some streaming server as woonza, red5, flash media server to play the streaming?

    JavaFX does not support flash streaming.
    JavaFX does support http live streaming: http://en.wikipedia.org/wiki/HTTP_Live_Streaming
    JavaFX does not support audio/video capture (there are other java/native libraries that do that).
    See:
    Video camera capture/streaming: example implementation "Thread: Video camera capture/streaming: example implementation"
    http://javafx-jira.kenai.com/browse/RT-3458 "Camera and Microphone" (go vote for this jira to get some capture technology built into JavaFX).

  • Problems in sound capture and JMF deployment

    Hello:
    I am new to JMF.
    I made an applet using JDK 1.3 on JBuilder 5. This applet captures and plays audio. When I run it through JBuilder's IDE, it runs fine. But when I run it independently, the applet's GUI appears but sound recording doesnn't work. Remember that I have JRE1.4.2 and JMF2.1.1e installed on my machine.
    When I installed JMF, I enabled the recording, and file writing options for an applet.
    To further check the problem, I ran it through JMF debugger. There I found that it says that ,
    <permission javax.sound.sampled.AudioPermission "record";> is not enabled.
    To enable it I added this entry in java.policy. This allowed the audio capture to work.
    But my question is,
    1. Why isn't this entry present by default in java.policy?
    2. Even one of my user entered this entry in java.policy, but was unable to capture audio.
    3. I want my applet to be running with different users having different versions of JRE,JMF and browser settings. How can I do this, without asking my user to do anything? I simply want that when my user downloads this applet, I should provide him with some installation file that installs JMF as well as configures everything on the system in a way that he can use this applet easily.
    Haven't you guys faced such problems in deploying JMF stuff?
    I'll be grateful for any help.
    Thanks
    Jami

    Hi.
    I am facing very similar problems: it looks like deploying JMF with Java Applets is really a challange!
    On my own test installation, if I enable audio capture and file writing for applets through the JMFRegistry, then I am able to record audio from my test applet, even when executed in the target web browser.
    Nevertheless, how to deploy the applet in such a way clients won't be required to manually install JMF and enable audio capture and file writing through the JMFRegistry?
    It looks like the JMF Customizer is able to produce a custom JAR also embedding user preferences for audio capture from applets and file writing , is this correct?
    Any help would be greatly appreciated.
    Regards,
    Marco.

  • Capture and Export of Mono Audio in FCP HD

    I have just upgraded to FCP HD from FCP 3. My problem is all of my audio needs to be Mono only. In v3 this was simple I just chose Mono from the capture settings and Mono for Export.
    On FCP HD I can't find any way to capture and export as Mono. When I record Voice Over in FCP all I get is the right channel and even when I set it to pan centre it still only comes out the right speaker after export.
    If I've got to manually duplicate tracks everytime it will take me forever.
    Anybody know a simple way to capture and export Mono only (the same for both Ch 1 + 2)
    G4 DP 1.25   Mac OS X (10.4.6)  

    This might seem the long way 'round but it may save a ton of time in the end.
    Do your FCP mix in stereo as Colin suggests, then take the final audio track into STP or Peak and do a "mix to mono" and then save a new AIFF file with the resulting mono clip.
    Then bring that back into FCP on a new audio track, line it up with the stereo, then either disable or delete the stereo tracks. This will give you a true mono audio track.
    But where are you going with this content that will handle mono audio? DVDs require a stereo AC3 files. Are you sure you really need a mono sound track?

  • Live Capture with a camera via firewire and usb audio interface

    I am trying to do a live capture through Final Cut 7.
    I want the video feed through the firewire from my HVX200 and the audio feed from a 4 channel usb audio interface (Alesis iO4).
    When I have both audio and video input coming in from the HVX200, the live capture works fine.
    However, when I change the audio input so that it is coming from the usb audio interface, final cut has an error message saying "Video is not available."
    During the preview, I see the video clearly and am getting levels from the iO4.
    But when I try to capture, I get the error message.
    Is it a processor issue (I've attached my specs below) with problems handling 2 separate inputs?
    I'm not quite sure what the problem is.
    Any input is greatly appreciated.
    Thanks!

    Hi MtD,
    Yes I am changing the Capture preset to iO4.  Once that happens, it lets me run both the camera and the iO4 into the laptop but then an error message pops up the moment I try to capture it.
    I was only trying to use 3 out of the 4 channels of the iO4.
    Thanks!

  • Is it possible to do the audio capture and playback simultaneously?

    In short :
    Is it possible to do the audio capture and playback simultaneously? . If it is not supported directly by Sun, pl suggest another way to achieve the same.
    In detail:
    I am doing a voice chat application by using the streaming through UDP . I am able to play the byte stream. But , is it possible to capture sound simultaneously (while playing the audio) to send to the other end?

    If you're Airplaying from you computer, you might be able to do this. Here's what I would try:
    Go to the Airplay icon in iTunes. You should see both your Apple TV and your speakers listed as options. Select "Multiple speakers." You'll see both devices together. Turn the volume all the way down on the Apple TV. You should be getting the video on the TV, but only hear audio through the speakers.
    Using the "Multiple Speakers" option will sync the output of your devices so that the sound matches the picture.
    I haven't tried this myself, but I'm thinking this would work. However, this approach will only work when using Airplay from your computer – not from am iPad or iPhone – as they don’t have the "Multiple Speakers" option (as far as I know). It also won't work with content streamed directly to your ATV, obviously, because there's no way to stream from ATV to other devices.
    Let me know if this works.

  • Audio video capture and combination Nintendo64

    Hi
    I was hoping that someone could help me with mixing a video and audio signal for live playback.
    I have a N64 with its video component hooked up to my TV capture card, and the audio connected to the line in on my sound card.
    the computer i'm using has a fresh install of arch, with xfce. I currently just have alsa installed, as far a sound stuff goes and everything is working fine.
    right now i can see the video from my nintendo with "QT V4L2 test utility" which is all good. I can't make this video full screen or any bigger. I do know i can use cheese to view the video in full screen, but it does not handle any audio.
    so, what program can i use? or how can i play captured audio live?? is there a program (something like cheese or not) that can handle the capture and playback of both audio and video????? the latter is prefered
    any input would be good, some ideas could help me along
    thanks guys

    ok cool VLC seems like a good option, i can capture the video just fine becasue i know the video device name is /dev/video0 but i don't know what the audio device name is..
    i have been looking online for a way to find this out. but i have not yet found a way to tell me what the audio device name is for my sound card. (i have the audio input connected to a PCI sound card)
    i just found this which helped a bit
    http://forum.videolan.org/viewtopic.php?f=32&t=81166
    it turns out that when i have a look the sound card i want to use is alsa://plughw:0,0
    so i go -> show more options -> play another media synchrously and enter alsa://plughw:0,0. all goes well

  • How Do I Transmit Audio from My 2008 MacBook Pro to My 2011 Samsung HDTV?

    Hello,
    I'm trying to transmit audio from my 2008 late model MacBook Pro to my 2011 Samsung HDTV.  My MacBook's Model Identifier is MacBook Pro 4,1 (ancient, I know).  I purchased this DVI to HDMI cable which does a beautiful job of transmitting the video to my HDTV, but no audio (as advertised): http://www.amazon.com/gp/product/B000E8SY5Q/ref=oh_o02_s01_i00_details   HELP!!
    Thanks very much.

    I figured it out!  I plugged in my 3.5MM auxillary cable I use to plug my iPhone into car stereo jacks from the headphones port on my MPB to the "PC/DVI Audio In" on the back of my Samsung HDTV and voila! It worked! No additional cables (other than these two). No upgrading OS.  Yay!   
    Here's the auxillary cable:  http://www.amazon.com/AUDIO-3-5MM-JACK-AUXILIARY-CABLE/dp/B002Q3K0QS/ref=sr_1_1? ie=UTF8&qid=1330576344&sr=8-1
    This looks like a great workaround to the MPB to HDTV audio problem!  Hopefully my geek status is still intact.  W00T!
    When in doubt, try all the cables you have in all the different ports.  AV hasn't changed much over the years and you can often rig things to work with what you already have.  Yay for keeping cables out of landfills and repurposing!

  • CS3 - Video freezes on Capture and Playback - Please Help!

    Hello all,
    Here's the problem:
    When Capturing footage via firewire from Mini DV, shot in standard DV, within a standard NTSC-DV Widescreen 48k Project, the picture freezes after 1 second.  The audio can still be heard and the footage actually does get captured.  However, after the footage has been conformed, and we load the clip into the Source Window and hit play, the video again freezes after 1 second of play.  Again, the audio keeps playing and you can move the marker anywhere on the clip and see that all the footage is indeed there, but as soon as you go to play it from any point - same thing, the picture freezes after 1 second of play, making editing impossible.  The clip is being captured as an .avi and all capture settings appear to be correct.
    Here's the kicker:
    - HDV video captures and plays back fine.
    - The DV video captured correctly at first, this has been a recent problem going on now for several weeks, after no changes to the system.
    - The biggest kicker - after trying successfully to capture, playback and edit HDV video, we closed Premiere, reopened, tried to play the previously captured DV footage and it played just fine suddenly!!!  Then we closed the program, re-opened and tried again - back to the freezing problem and it never played back fine again...
    Here's the specs (I can give more specifics later if needed, it's my partner's computer):
    Sony PD-150 DV-Cam (but recording on Mini DV in standard DV mode, not DV-Cam)
    Windows 7
    Intel Core i7 3.20 ghz
    Asus X58 Motherboard with onboard Audio and Firewire
    6 GB Ram
    Nvidia Geforce 9 Series with PhysX
    Please help if you have any idea how to solve a crazy problem like this.  Thank you!!!
