Captivate4: Multiple audios playing simultaneously

Hi there.
I have a project with multiple swf's (all on separate slides), each with its own audio.
Everything plays normally on my desktop, but when the project is SCORM 2004 packaged and uploaded to my LMS, the audio for about 5 slides plays simultaneously for the length of the first introduction slide (which incedentally has no audio).
Once the first slide has finished (it has a couple of text instructions and a "Next" button), and the user continues to the next slide, the audio garble stops.
I think that for some reason the audio is being played as the swf files are being downloaded from the LMS?
I have all animations set to be stored externally in the project (that is the only way I can get them to operate correctly), and the download 'buffer' to 80%. Framerate is 30fps.
Any ideas?
Thanks in advance.

Rod, if I learned something I would believe what you say. But to 'learn' one must discover something they didn't know, or correct something they were doing wrong. Sure, I didn't know Captivate would go crazy when I externalised the files, because it shouldn't. I have learned nothing from this, other than Captivate has idiosyncracies I no longer have time to deal with. I am going to continue using the product for small, less important projects, but it is no longer practical for me to use as a serious education tool.

Thanks for responding though.

How to play multiple audio tracks simultaneously?

Hi there,
I am having problem with playing multiple audio tracks. I want to play 2 or more audio tracks at exact time (without delay) - is it possible? how can it be done?

So, essentially, you're trying to take a recording of say, a singer and a guitar player, and end up with the singer in one file and the guitar in the other. Got it.
[http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/Merge.html]
That sample will merge multiple input files into a single file. Because you want to play the files together rather than save them, just take the sample and strip out all of the DataSink stuff, and add the following line right after the Processor "outputProcessor" is realized...
outputProcessor.setContentDescriptor(null);
So, it'll make the following revision to the code:
     // Create the output processor
     ProcessorModel outputPM = new MyPMOut(merger);
     try {
         outputProcessor = Manager.createRealizedProcessor(outputPM);
                    outputProcessor.setContentDescriptor(null);
         outputDataSource = outputProcessor.getDataOutput();
     } catch (Exception exc) {
         System.err.println("Failed to create output processor: " + exc);
         System.exit(-1);
     }That'll make the outputProcessor play the file, as if it was a Player object. You won't have any visual controls, but if you need visual controls, then don't do that, and just create a Player object to play the outputDataSource.

I would like to create a movie with with video from multiple windows playing simultaneously

I would like to make a movie that shows multiple videos playing at the same time but in separate windows (kind of like the intro to the Brady Bunch?). How can this be done?

Thank you for using the Apple Support Communities
I would suggest using Apple's Pages which allows support for imbedding videos from the device's camera roll. Pages also allows for sharing via email, Air Drop, and Messages.

How do i play multiple audio files simultaneously using AudioQueue?

I've basically gutted what I don't need from the "Speakhere" sample app and I'm left with something I can use to play audio files. I converted wav files to aiff and then renamed the aiff to caf (Just in case this matters). I even tried shortening the files to 10 seconds long, but no difference. I am able to play files singly, but am unable to play more than one file at the same time. When I try to play multiple files, the first one plays correctly but the second will play a horrible long beeping sound. Sounds almost like a buzzer and sometimes will sound like a high pitched beep. My code has all the audio components like the speakhere app (AudioQueueObject, AudioPlayer, AudioViewController). I've changed the AudioViewController to be just my "AudioController" class where when I initialize, I pass in the name of the file and it replaces this line of code:
CFStringRef fileString = (CFStringRef) [NSString stringWithFormat: @"%@/Recording.caf", self.recordingDirectory];
with this:
CFStringRef fileString = (CFStringRef) [NSString stringWithFormat: fileName, self.recordingDirectory];
Any suggestions? I've been yanking my hair out trying to figure this out and I simply can't. I'm about ready to pull an "Office Space" but instead of beating up a printer, I'm going to destroy my macbook.
*NOTE: I have only tried this in the simulator, but I'm assuming it will do this on the real thing so I haven't bothered to try.

Unless I'm mistaken, you need one AudioQueue object for each audio file you want to play. In one of my apps, I basically copied the code provided in the [AudioQueue programming guide|http://developer.apple.com/iphone/library/documentation/MusicAudio/Concep tual/AudioQueueProgrammingGuide/AQPlayback/chapter4_section_1.html#//appleref/doc/uid/TP40005343-CH3-SW1] and made a wrapper object for playback. So then you can do something like this:
MyAudioManager *manager1 = [[MyAudioManager alloc] initWithFile:@"file1.caf"];
[manager1 play];
MyAudioManager *manager2 = [[MyAudioManager alloc] initWithFile:@"file2.caf"];
[manager2 play];
// etc...
If you want to play short files (~10s or less), you can use the simpler AudioServices functions along with SystemSoundID's. It will work fine if you have playback from AudioQueue and AudioServices at the same time.

Re: Problem with multiple Players playing simultaneously

Hi
Thanks for your responses. There is a further sample available at SUN under http://java.sun.com/products/java-media/jmf/2.1.1/solutions/SwingJMF.html that demonstrates multiple simultaneous Players (though not very reliable on my System - Win2K). So I know that this is possible. Nonetheless modifying the original code by setting the Manager's Hint property PLUGIN_PLAYER to true will also cause an error here when I try to instantiate a second Player. Setting that value is required in my case, as otherwise it is not possible to obtain the FrameGrabbingControl from the Player instance, which is needed to access single frames. So I'll try to install another Codec on my machine or will do a test using QT.
Regards
Achim

Hi
Got that xxx thing running now. Didn't take the approach by Andrew Davison but the one from the SUN sample. The latter in fact is based on a Processor instead of a Player. Instead of utilizing the FrameGrabbingControl there is a customized Renderer implementation to perform the conversion of video data to texture image. Even this was only succesfull when I installed some different codec (fobs4jmf).

Multiple clips playing simultaneously

Hello,
I am a complete newbie to Final Cut Pro. I have this movie I want to make which I can't do in iMovie. The video is a song I wrote with me singing all the parts, and I want the movie to show all the clips of me singing simultaneously. I managed to film all the clips, and get them spliced and named in final cut pro, and I have the audio file locked in the right place. Can someone tell me the basic command I need to use to get the simultaneous video clip thing going? Hopefully I'll be able to read that section of the manual and make it work, but I have no idea where to begin.
Also: what is the deal with rendering? If I've got this straight, I have to render a clip each time I've changed it in any way in order to view it in the Canvas?
Thanks,
Dave

Wow, this is fantastic, thanks a lot. Now that that's answered, I'm getting more ambitious - got any tips on how to get the clips to change size and move around during the movie?

Multiple audio tracks playing at the same time?

Does the Adobe Elements 12 allow us to have mulitple audio tracks playing at the same time? Is there a limit to the number of tracks?
Thanks!

Hi Jennifer3211,
Yes you can play multiple audio tracks simultaneously. The maximum no. of audio tracks can be 99.
Thanks

Play audio files simultaneously ?

I only have iMovie '08, Garageband '08 and and regular Quicktime. I'm trying to recreate a song by recording the guitar1 part, the guitar2 part, bass, and vocal parts and then putting them together. I tried doing this using iMovie and Garageband, but it wouldn't let me have more than one video file. I don't know how to export just the audio from iMovie, and I know with Quicktime Pro you can view multiple clips at once, which would be perfect, but you can only play one audio at a time.
I would be more than willing to buy Quicktime Pro, but iLife is a little too rich for my blood. Anything in the $50 range that would help me accomplish my goal would be MUCH appreciated!! Thanks!

I was actually referencing your video, in which you deleted all of the audio except for one. If all your movies had different audios, had you not deleted it would they have all played simultaneously?
Thanks for posting the link so I would know to which movie you were referring. Answer above assumed you were trying to play multiple movies in separate players simultaneously. In this case, where I placed several, differetnly compressed video tracks in a single player, I did only use a single audio track since they were all the same AIFF (Linear PCM) content and I wanted to save what little file space I could for online viewing purposes. To answer your question, yes, if multiple audio trackes are layered to the same player over the same time interval and all of these tracks are activated (simultaneously checked for playback) then all of the tracks will play simultaneously.
Here is an "S&G" example of a file in which selected segments of the audio and video content from one movie are layered over the audio and video of another movie for simultaneous "picture-in-picture" playback as requested by another QT forum user. SAMPLE 012
There is also a third interactive, multiple audio/video track option in which the viewer can switch between the display of individual video tracks in the same player display area while either playing all of audio tracks simultaneously or only playing the audio associated with the currently displayed video track. While this is emplimented relatively easily using QT Pro, the switching of playback content is not always all the smooth and the file size overhead can quickly maunt up. Still, it might be an interesting effect if you are playing all of the various instruments and doing all of the vocal parts. Biggest proble would likely be the synchronization of all the content of the various tracks. The hook here, of course, is the fact that the viewer can, at his or her whim, cycle through the various tracks unlike cutting and pasting various track segments in a fixed playback order. Oh, well, just some more "food for thought" for the creative QT Pro users.

Is it possible to play two audio files simultaneously.

Hi,
Is it possible to play two audio files simultaneously.
I modified the 'SpeakHere' to play two audio files simultaneously, it worked perfectly on simulator but get hanged on iphone.
To this I implemented NSTimer, which regularly checks for both player instance every second.As soon as any player gets stopped Timer task stops the second one forcefully and again starts both.
thanks.

Hi Jay
Do you have the eLearning Suite? If so, you have Adobe Presenter available to you. If you don't, you should be able to download the Presenter installation file and evaluate it.
Presenter is an add in for PowerPoint. The neat thing about it is that it provides for a Table of Contents type of functionality as you see is configured in Captivate. But the twist with that is you are able to do something you cannot do in Captivate. You are able to insert videos inside the TOC area!
Just musing out loud... Rick

Movie Playing multiple audio tracks & echoing

I have a movie that is in a symbol that i want to play after a set amount of time by using setInterval. The function works - but when it shows the symbol and plays - it plays multiple audio tracks at the same time - sounding like an echo and or a 1-2 second delay on the same audio track. It also seems the audio starts playing on the main root without actually triggering the playhead of the video symbol.
Following is the code i am using for both timer and the video. Any pointers?
// interval
         var timer = setInterval(onTimer,10000);
         var mysymbol = sym.getSymbol("btn1_video");
         // function
         function onTimer() {
            // clear last interval
            clearInterval(timer);
            // action
            sym.$("btn1_video").show();
//and on on the movie symbol timeline trigger:
var vid = $("<video width='818' height='460' autoplay='autoplay' preload='auto' controls='controls' id='videoID'>" +
"<source src='video/testvideo.m4v' type='video/mp4' />" +
    "<source src='video/testvideo.webm' type='video/webm' />" +
   "<source src='video/testvideo.ogg' type='video/ogg' />" +
   "This browser is not compatible with HTML 5" +
"</video>");
sym.$("btn1_video").append(vid);

You identified the problem. I thought that you had to highlight the first song to get the playlist going, but all that does is make the first song repeat itself. Thanks for the guidance.

MPEG-4 ( H.264 ) Movies play ALL audio tracks simultaneously

In i-Tunes , when I try to play MPEG4's with multiple audio tracks (such as 1-english 2-director comment)both audio tracks play at the same time.
The files are MPEG-4's created by Nero Recode (AVC – HDTV profile).
There is no issue with any similar files with one audio track.
There is no issue playing these in VLC , WMP Mplayer, etc.
Is there an option to enable i-Tunes to allow me to select only one track?
Vista Ultimate 64-bit installed on a Core 2 Duo E6600 2.4GHz dual core CPU

Or, could someone explain how I might be able to view the file information in Terminal?

Can AppleTV play multiple audio tracks in a movie?

I recently discovered (pretty much by accident) that iTunes and the iPhone supports multiple audio tracks in a single m4v video file. So I've started ripping my DVDs using Handbrake with both the main audio and the commentary track.
In iTunes and my iPhone I can swop between the two at will, but I cannot find any information on how or if it's possible to switch audio tracks on the AppleTV. Does anybody know?
I'm using an AppleTV 2 with up to date software and iTunes 7.6.2 set up to sync.

this same question was asked in the last 2 days (and may even be still listed on page 1).
http://discussions.apple.com/thread.jspa?threadID=1541440&tstart=15
however, the answer is no.

Multiple audio playback devices

I have just built a system using the K7N2-L mainboard and am having a problem with multiple audio playback devices.
Actually I have TWO problems, which are probably unrelated.
I have a 5.1 speaker system connected to the onboard audio and an external USB DAC for playback through a hi-fi system.
The first problem is that the USB audio device is only recognised if it's plugged in after the system is booted. If it's already attached when I power up, it appears not to be properly installed.
The second problem is that when I use the Sounds and Multimedia control panel to switch audio devices (Windows 2000 pro) playback continues through whichever device was used first. In order to switch, I have to reboot the computer.
Another system I built using an Epox nforce board does not have this second problem, although it does have the first. With the Epox board, I can even play through both devices simultaneously.

I gathered this from the handbrake side of things:
You can also combine Pro Logic II and AC3 pass-through. This will give you a file that will play anywhere from QuickTime to VLC to the iPhone (using the AAC Pro Logic II track) and play in true surround sound on an AppleTV or in Perian. It is the best of both worlds, and it is only possible in the .mp4 and .mkv containers. Again, MP4 file names must, confusingly, end in .m4v for QuickTimeto read them. To use this hybrid format, in the Audio tab, set the first audio track to be the track you want, in AAC sound. Then set the second track to also use the same source track, and select AC3 pass-through."
I think this is what will ultimately help me. I will let you know.
the answer was righ under my nose.
Thank you!

[SOLVED] ALSA multiple audio source playback

I noticed that by default alsa doesn't allow for playing from two or more sources simultaneously. For instance playing a youtube video while already playing music from mpd will result in having only sound from mpd. How can I enable playback of multiple audio sources in alsa? Thanks
Last edited by hesse (2012-07-13 22:24:29)

I put this in /etc/asound.conf
pcm.dsp {
type plug
slave.pcm "dmix"
and left the settings in mpd.conf like this:
audio_output {
type "alsa"
name "ALSA Device"
The mixing now works with multiple audio sources! Thank you.

How to edit a multiple audio video clip on Premiere

Hello everybody
Maybe this is a dumb question, I'm sorry if I'm asking what is obvious for you, but I swear I tried to find on the web and on this forum, but I couldn't find anything.
Well, I made a video using a screen capture software called Dxtory, that provides me the ability to record my PC screen, with multiple audio tracks.
Ok, now I have a 15gb avi file. When I open this file in the Media Player Classic, I can play one or both channels. The first channel is the original audio captured from my PC. Every audio generated by my PC is in this track. The second track is my voice, with my commentaries. I have all of this in one single file. They are not splited. It's just one file.
Then when I import into Premiere, the software just recognize the video track and the first audio track. I can't find the second, with my voice.
I know I can split the clip into 3 files (1 video and 2 audios) but it would take longer. I just want to drop the file on Premiere and edit the audio volumes quickly, because when I talk I would like to low the volume of the PC audio.
Now, the question: Is there a way to Premiere recognize both tracks in this single file? How?
Thanks in advance for any help.

I'm actually surprised that Pr can import this at all--the video is Xvid. Maybe it's some variant that Pr's importers can handle, as Jeff suggested. I dunno--it doesn't play well for me, regardless, and I'm not going to install the Dxtory codec to find out.
Anyway, to the matter at hand: while AVIs can, apparently, contain multiple audio tracks, Pr's importers are limited to a single track. However, Pr has other importers than can handle multiple audio tracks. QuickTime--which is a wholly different process--supports multiple audio tracks, as does MXF (some flavors). However, Xvid in QuickTime (which is feasible) won't import in Pr (at least on a PC), and Xvid won't go into an MXF file at all; that means you'd have to transcode. Personally, this would be my choice--but I found that the original clip played back pretty terribly, so that would be why I'd go that route.
Additionally, you could extract the second audio track to a separate WAV file, import both the AVI and WAV, and then use the Merge Clips feature to marry them together as one pseudo-clip. Not perfect, but it would work. The benefit is that you don't re-encode anything.
So, I've got solutions for both the re-encode/MXF option (my preference) and the AVI/WAV option. Here's proof of the MXF (transcoded video to XDCAMHD422 50Mbps) with four audio channels (stereo must be split to dual mono):
At the end of the day, these (or a variation of them) are your only options. Pr simply won't import multiple audio tracks (even dual mono) in an AVI container. Let me know if you're interested in either of the solutions.
