Is it possible to play multiple media sources simultaneously via ATV2?

This may seem strange but I would like to play video through the ATV2 menu on my TV AND at the same time play a separate audio (a song or podcast) through the same ATV2 via AirPlay. Both media are iTunes/APV2 supported and work great when played separately but I'd like to play them at the same time through ATV2 which is connected to my main B&O TV/speakers. I guess I could create a file or some other media file that combines the sources I want as a new playable file but I really don't want to go through the hassle. I like watching some video programs (eg, sport classics) and listening to my favorite music on iTunes at the same time.
Thanks for the help.

No I don't believe this is possible

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!

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.

Capturing multiple DV sources simultaneously?

Can I capture from multiple DV sources (not HDV) simultaneously with Final Cut Express?
I want to record a live event using two DV camcorders.
PowerMac G5 1.8GHz, 1GB RAM Mac OS X (10.3.9)

Not into a single computer. You need two computers.
Is it possible using a faster PowerMac or with Final Cut Pro?

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.

Is it possible to play multiple videos in sync?

I need to build a website which shows multiple instruments in a band, being played in sync. Each camera/video block is a different instrument, and played together, they constitute an entire band. I have been searching high and low for ways to do this, and it definitely appears that HTML5 is out. It looks like standard FLV progressive download is out, too, because it's impossible to get 4-8 videos to sync perfectly.
I see on the FMS page that it has some abilities in synching. How would one (conceptually) go about making a webpage where say 4-8 videos begin to buffer, then when ready, play in sync? And they would also need to, when the location is changed, all sync to that location and rebuffer.
The objective is so that the user can mute/solo each video's audio, to remove an instrument(s) from the "mix" at any time.
An alternative way of doing this, I think, would be to just put the 4-8 videos together in video editing, and encode this into one video, but have each video's audio track be a separate audio channel. If FMS can do multichannel audio on one video, this might work, if it could mix them in/out individually, as the user requires.
Any insights on this problem would be greatly, greatly appreciated.
Thanks!

sandyaudiovisual,
Very good point. I was, in a way, asking both.
Yes, it appears that actually streaming multiple streams of video while visibly playing in synchronization simultaneously will be very difficult.
So, I was thinking that as an alternative, I could pre-mix the multiple "streams" of video into just one video. E.g., a single video file, with for example five squares each with a different video inside of it. So to the view, in a sense, it looks like five streaming videos in sync.
What I would then want to do, in that situation, is be able to mute/solo an audio track associated with each "video". In reality, it would be a single video channel, with five audio channels, switchable while maintaining synchronicity. Though the extra wiggle is that rather than simply switching between 1 and 5, it would be preferable to actually mix in/out channels 1-5, so that at any time, 1, 2, 3, 4, or 5 audio channels would be playing, in synchronicity, and could be muted/soloed.
To give a visual idea, there would likely be a mute and solo button composited on top of each "video" box inside the main video.
It would be easier if we could actually stream five separate video files and have them be in sync, with all stopping to wait should one need to rebuffer, and all sharing the same transport controls, because then if we want to swap out one video, we just swap that file, rather than remake the entire file in Final Cut or whatever. But this is sounding less and less possible.

Possible to have multiple data sources within 1 SQL querey?

Hi All,
Is it possible to join to a table in a different datasource within 1 SQL Querey?
Something like...
Connection 1
Select *
From Table
Join
Connection 2
On
Connection1.Table1.Field1 = Connection2.Table2.Field2 Thanks,
John

Johnbr (Oracle11G) wrote:
Is it possible to join to a table in a different datasource within 1 SQL Querey?Called distributed joins - joining a table from one database with that of another database. Also possible to do heterogeneously across different database products - e.g. joining an Oracle table with a SQL-Server table.
As already explained, some kind of communication interface is needed from the local database to the remote database, in order for the remote table to be read and joined to the local database. This interface is called a database link in Oracle.
The basic steps. First define the database link:
create database link <linkname>
connect to <account>
identified by <password>
using <connection-string>Complete syntax details and examples are in the SQL Reference Guide (see http://tahiti.oracle.com)
After the database link has been identified, you should now be able to address remote tables as follows:
select * from <remote-table>@<link-name>A distributed join would look something like the following:
select
from <local-table> t1,
<remote-table>@<link-name> t2
where t1.. = t2..However... this is almost always a BAD IDEA to do distributed joins. It seldom performs well. Performance is immediately constrained to the speed, bandwidth and latency of the network link between local and remote databases. It cannot scale with data volumes and increased frequency of use.
So if the remote table is not small, the network link not robust and reliable, and join not infrequent, it is bad idea to make use of distributed joins. In which case other alternative (and far superior) features need to be considered instead - like materialised views.

[SOLVED] Single audio source (can't play multiple audio sources)

Hi,
I have been having this problem in my arch laptop for a long time until I decided to put an end to it. I am using Gnome 3 and pulseaudio, and whenever an app "grabs" the audio, it won't release it, meaning no other apps can play sound. Even when one firefox tab grabs the audio (for instance, Gtalk notifications, youtube videos...) no other tabs can play it. I can avoid the problem if I reload the tab, or close the app.
Is it a weird problem? Is it related to pulseaudio? I haven't found information related to this.
Thank you.

Multiple data sources to open hub destination ??

Hi,
Is it possible to assign multiple data sources to open hub destination?
At present we are FTP'ing a file to users. Users need one more field added to this file. The information for this field belongs to another ODS. I checked the infospoke but it does not accept multiple data sources.
Any ideas?
Thanks!
Edited by: BI Quest on Sep 4, 2008 8:12 PM

You can create multiple transformations for open hub destination. Create destination of open hub destination to be file on application server and then use transfer mechanism to transfer files to desired destination.

MP3s won't play correctly in Media Sourc

I just downloaded Media Source 5 (5.0.38) for my Zen. I have discovered quite a few of my previously ripped MP3 suddenly don't play right. They played great in 3.30.2 and still do.
I ripped all of these myself several years ago. A single version of MusicMatch was used to do all the ripping, hundreds of CDs.
I've discovered this pattern. If one track of a CD is wrong, all tracks from that CD play wrong. Otherwise all tracks of the CD play perfectly.
With Media Source 5, when I start play on a bad track, the progress bar zooms across at about 0 times normal speed. When it gets to the right end, playing stops, despite the song being far from finished.
So I tried the MS Media Player. Also bizarre behavior. The bar shoots across just as fast, but the song doesn't stop with the bar hits the right.
Media Source 3 always works correctly on all mp3 files. Trying to find a pattern, I tried other mp3 players. Here is that result:
These are the ones that play it correctly:
Creative MediaSource 3
Nero Showtime
MusicMatch
PowerDVD
Garmin GPS
Wrong:
Creative MediaSource and mp3 player 5
MS Media Player
Based on the above pattern it doesn't make sense to be that just some CDs could be "damaged", since either all tracks or none of a CD are "bad". Also, the same program was used to rip them all. They play fine on most players, just not MediaSource 5 and MS Media Player .
Has anyone ever heard of this? It there anyone here that can examine a sample file and figure out what's "wrong" with it's My purpose here is to discover whether this is a player problem or something else. MediaSource could be using a Windows resource to play mp3 files which would explain why both it and Media Player both fail.
Thanks.
Bruce.

I want to play multiple speakers off one Airport. is that possible?

I have an Airport express in my living room, but i want to have wireless music in my kitchen and bedroom. Would i need to buy an amplifier and connect it to the airport or can i play multiple speakers off one Airport OR should i buy multiple Airport's to achieve this?

You can either use multiple AirPorts or use an audio system that pipes music to speakers throughout the house.

How to play MPEG4 music files using Creative Media Source

I use iTunes store for buying music pretty much and receive files in MPEG4 format.
Instead of converting to MP3 I would prefer that my Creative Media Source player/organiser could handle the MPEG4 format. I'm using the Media Source player with an Audigy2ZS and sometimed the older Soundblaster-USB for notebooks.
Is there an upgrade that I have overlooked or ...
Or shall I buy a more professional player, like BMP studio?
I don't like the iTunes player very well!

Multiple RTMP sources streaming to FMS without stop?

I have some .mov files want to stream to Flash media server by ffmpeg.
i have already tried to stream a single .mov by FFMPEG command in terminal and it works, the FMS can display the thing i streaming in live.
ffmpeg -re -i file1.mov -vcodec libx264 -f flv rtmp://localhost/livepkgr/livestream
Now i want to stream multiple files as one source, i tried to use above command one by one,
but it seems Flash media server stop the streaming when file1 is finished, then start the stream with file2.
It makes the stream player stopped when file1 is finish, and i have to refresh the web page in order to continue on file2.
i am calling the FFMPEG command by a C program in linux,
i wonder is there any method that i can prevent the FMS stopped when i switch the file source in FFMPEG?
or is that possible to let FFMPEG constantly deliver the stream by multiple files source without stopped when a file finish?
Sorry have for asking a lot recently... but this is urgent to me... thank you

i am trying to prevent fms pause the publishing the video after publisher stop.
i tried to comment out all the codes in this 3 method in main.asc
application.onUnpublish = function(clientObj, streamObj)
Client.prototype.FCUnpublish = function( streamname )
Client.prototype.releaseStream = function(streamname)
but still when publisher stop, the client side player stop imeediately.
Also i am can fms receive the stream as soon as possible, and let the video play until the end?
for example
i have a video have 5mins length, my publisher software can fast enough deliver the video
within 30 secs, so that fms should already have 5mins content for broadcasting, can fms
keep on the broadcasting even the connection from publisher to fms is finish?
