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?

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

[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

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.

Increase performance in a multiple data source report

CA Forum: General
Hi everybody.
I have a big problem, when i make a report that have multiple data sources the performance decrease considerably, i still don't know the reason. Is it true that using multiple data sources is too slow?.
I tell you a fact: I made the report connecting via "Field Definition File", and it take at least 2 minutes to show itself but it only have 170 records, and i'm very sure that the sql statements to each data source were executed very faster.
I even heard about index, but i think they only are useful when i connect directly to the database.
All my partner told me, that Cristal Report
Thanks you in advance

Thanks you, but I explain better what i was doing.
I've made a report called "Kardex de Producto" which show the behavior of the products according to its sales, purchases.
The end result which is showed by the report is correct. I used three data source in the report, so links between each table is correct. The only problem i have is the performance because i still don't know why is too slow. In fact the sql statement is very heavy, but i think it doesn't matter to the report because when it takes the data from the database (connecting via Field Definition File) even if the very heavy sql statement returns twenty record Cristal Report must show itself very quickly. I don't want to believe that Cristal Report is very slow when it works with multiple data sources.
Do you mind if i give you my report? if not please leave me your email address.

Report Viewer and Multiple Data Sources

I know that it is possible to create a report in Crystal Reports using multiple data sources. But is it possible to use just the Free Report Viewer to view a report with Multiple Data Sources?
Our company uses Crystal Reports XI. I do not use the program myself, I am in the IT Department. I have limited knowledge of Crystal and do not do any of the report writing.
If this is possible, and if someone could help me out with what would need to be done, or point me in the right direction of a Knowledge Base or Help Topic that explains this, that would be great.
Thanks.

I believe it can but both data sources need to be set up. Ask a report designer to help you use the Designer to test this and see what is required.

Any examples of a data template using multiple data sources?

I'm looking for an example report using multiple data sources. I've seen one where they do a master/detail but I'm just looking to combine results in sorted order (sorted across all data sources). The master/detail used a bind variable to link the two defined queries, I'm thinking what I want won't have that, so I'm lost on how to make that happen. I have reports using multiple sql queries and there is a way in the data source pulldown to tell it to combine the data sources. It appears to be a more manual process with data templates, if it's even possible.
Any pointers/links would be appreciated.
Gaff

Hi Vetsrini :
That's just it. Mine is simpler than that. There is no master/detail relationship between the two queries. I have the same exact query that I run in two databases and I want to merge the results (ordered, by, say eventTime) in one report. So I think my results are going to be two separate groups (one for each data source) which I'll have to let BI merge vis XSLT or whatever it uses. That's fine for small result sets but for larger ones, it would be nice if the database did the sorting/merging.

Capturing multiple video streams into a movie file

I am using QTKit to capture 3 media streams simultaneously: audio, video, and display (display is screen capture), and would like to capture them in a time-synchronized fashion to a single .mov file.
I have been able to successfully capture these three streams to 2 separate .mov files by using 2 QTCaptureSessions (one for audio/video, one for display video), but the problem here is that the 2 files are not time-synchronized (I have no idea how to synch them after the fact).
The more intuitively correct thing to do is to use a single QTCaptureSession instance with 3 inputs (2 video inputs and one audio) to do the capture, which should automatically synch all the streams. Furthermore, since the .mov file can support an arbitary number of streams, I figured wiring up the QTCaptureSession to output to a single .mov file would be easy. I was wrong.
The problem is that even though my QTCaptureSession has 3 nice input connections (2 video and 1 audio), when I wire up a QTCaptureMovieFileOutput to it, the resulting QTCaptureMovieFileOutput object has ONLY 2 connections: a single video and a single audio.
Here is snippets of what I am doing:
// add audio input: (type of media is QTMediaTypeAudio), succeeds
[qtSession addInput:[QTCaptureDeviceInput deviceInputWithDevice: qtAudioDevice] error:&qtError]
// add video input: (type of media is QTMediaTypeVideo), succeeds
[qtSession addInput:[QTCaptureDeviceInput deviceInputWithDevice: qtVideoDevice] error:&qtError]
// add display input: (type of media is QTMediaTypeVideo), succeeds
[qtSession addInput:[QTCaptureDeviceInput deviceInputWithDevice: qtDisplayDevice] error:&qtError]
// create file output
QTCaptureMovieFileOutput * qtFile = [[QTCaptureMovieFileOutput alloc] init];
[qtSession addOutput:qtFile error:&qtError];
// PROBLEM: if I look at this array of connections, it has ONLY 2 connections
// 1 video, 1 audio!!!
NSArray *connections = [qtFile connections];
// start capture running
[qtSession startRunning];
// wire up to my file
[qtFileOutput recordToOutputFileURL:[NSURL fileURLWithPath:outputFileName]];
I desperately need help....my questions:
1. Since QTCaptureSession supports arbitary inputs, and QTMovie supports arbitrary # of streams, I can't believe it's not possible for me to simply "hook" all the inputs of QTCap to output connections that will write to streams in one movie file. Clearly, QTCaptureMovieFileOutput is not doing this...can anyone tell me how to do this? This can't be hard, right?
2. If I have to fall back on the ridiculous approach of capturing 2 unsynchronized .mov files and somehow synching them after the fact, can anyone provide a pointer on how to do that?
Thanks VERY much!

Multiple Data Sources In One Logical Table

I am new to OBIEE and I have came accross an issue. I appologize if this information is in the forum somewhere but I have searched and cannot find it.
My situation is that I would like to have one logical table that contains multiple data sources which have all the same columns. I already have session variables setup to differentiate the user's security through a row-wise variable for a specific column and a session variable for another column which determines the user's association to the data source in which they belong to. This security works well when the data sources are seperated in the Business Model and Mapping portion but the issue that arises is that the user's cannot share reports when the data sources are seperated in the BM&M.
I have dragged and dropped a table from the Physical model to the BM&M, I then dragged the second data source (with same meta data structure) over to the "Sources" folder in the first data source table in the BM&M. On the Content tab or each data source table I have defined the WHERE clause as such, where VALUEOF(NQ_SESSION."SCHOOL") session variable is my row-wise column filter and the VALUEOF(NQ_SESSION."GROUP") filter is my data source determinative:
sandbox."".SANDBOX.OBIEE_CROSS_ENROLLMENTS.HOME_SCHOOL = VALUEOF(NQ_SESSION."SCHOOL") AND sandbox."".SANDBOX.OBIEE_CROSS_ENROLLMENTS.DATA_SOURCE = VALUEOF(NQ_SESSION."GROUP")
Unfortunatley this only returns values in the BI Answers for the first drag and drop Pysical table in the BM&M layer and not the second Physical table drug into the "Sources" folder. I have also tried to create a new logical table and drag both tables into the "Sources" folder to no avail. I have experimented with the Fragmentation content on the "Content" tab of the seperate logical tables, checking the "This source should be combined with other sources at this level", which gives me an error in BI Answers that a column does not exist which really does.
What could I be missing? Advanced thanks to those who reply.
Thank you,
Kyle

Stijn,
Thank you for the article link. That was very helpful! It seems that I had a few things off as you do need the "This source should be combined with other sources at this level." checked. In my two table source columns for DATA_SOURCE I defined a literal ('086496' and '085597' for the other) in the Column Mapping tab. I pasted the following in the Fragmentation content, checking the "This source..." box on the Content tab:
eSIS.SANDBOX4_SCHOOLS.DATA_SOURCE = '086496'
And pasted the following into the WHERE clause, checking "Select distinct values" on the Content tab:
sandbox4."".OBIEE.NWOCA_SCHOOLS.SCHOOL_CODE = VALUEOF(NQ_SESSION."SCHOOL") AND sandbox4."".OBIEE.NWOCA_SCHOOLS.DATA_SOURCE = VALUEOF(NQ_SESSION."GROUP")
This took care of my user's security, utilizing the session variables in the WHERE clause. I am now able to generate reports that only one user can access from one data source and share that same report with another user who can only see data from the other data source.
Many thanks!!!

Multiple authentication sources with the same category

Quote from portal help:
"Multiple authentication sources can use the same category. However, because the prefix is prepended to the user and group names, you need to be certain that the domains involved do not have different users or groups with the same name. That is, if a LizaR user exists on one domain, and a LizaR user exists on another domain, they must be the same user because only one user will be created."
Fine, let's say I am "certain that the domains involved do not have different users or groups with the same name".
But there is other concern I have here. I want to know how portal will RECOGNIZE which authentication source to use?
Let's say I have 2 auth sources AS1 and AS2 with the same category MyAuth. AS1 use WS1 to authenticate against LDAP1 and AS2 use WS2 to authenticate against LDAP2.
Now, I have a user - Dmitry. I am trying to login into portal and I selected AS1 to do actual authentication. My question is how portal will CHOOSE which auth source to use because all portal knows about me is <MyAuth\Dmitry> that is came from portal login screen? Both auth sources match this pattern so seems like portal may choose any of them.
Does it mean that portal will try to authenticate again AS1 and if this attempt failed then you AS2?
I didn't find any explanation in portal documentation.
Thank you.
Edited by Bryazgin at 12/12/2007 10:42 AM

Yes, it seems you are right. As soon as portal have found CORRECT user there is no issue anymore because user is bind to unique auth source that actually has been used to created this user.
I think my main confusion come from the fact that having <Category> and <UserName> is not enough to UNIQUE identify user in portal as soon as <Category> can be the SAME for different auth sources.
Let's have you have user created by AS1. According API this user created by this AS1 will have 4 different names, like sUniqueName, sAuthenticationName, sLoginName and sDisplayName. But portal is going to search user in portal database BASED on information that is available in login form - <Category> and <User Name>. At this point portal has no idea about sUniqueName and all this things.
Now if there were 2 users in database that have been created by 2 different auth sources with the same <category> and <User Name> then I don't understand how portal will figured out which user to choose from. I guess <Category> value somehow MUST participate in sUniqueName value. <Category> has to be involve in process of finding user in database. In this scenario 2 users will be retrieved from database and what is important these 2 users are different, they have been created by different auth sources. Now question became which user is CORRECT one?

How to capture multiple change in webDynPro(ABAP) Table

Hi ,
I would like to know 'How to Capture Multiple Change' of a node . For example , a table is bound to a node and I select Multiple entries in the table . Then, how to capture Multiple entries of the table . Is there any method ?
There is a method 'GET_CONTEXT_CHANGE_LOG' of 'if_wd_context' which captures single change of the node .

Bursting with multiple data sources

Hello all,
I am working in a retail environment and we are building reports for the stores. There are several reports and they all receive the same reports. We are using BIP Entreprise with the bursting feature and it works very well.
The problem is that there are too many reports and we would like to combine all reports of the same store within the same PDF. We use the multiple data source feature and was able to concatenate all reports together.
Using this new report and template, we can not make the bursting functionality to work properly: the bursted report do not contain all the required report components.
For example, I have 2 queries A and B each producing reports for 3 stores: 2, 4 and 5. Without bursting, the output is as is:
Query A - Store 2
Query A - Store 4
Query A - Store 5
Query B - Store 2
Query B - Store 4
Query B - Store 5
With bursting into a file using the store number, I get the following:
File 1 - Store 2 - Query A
File 2 - Store 4 - Query A
File 3 - Store 5 - Query A
+ Store 2 - Query B
+ Store 4 - Query B
+ Store 5 - Query B
I would like to have the following output:
File 1 - Store 2 - Query A
+ Store 2 - Query B
File 2 - Store 4 - Query A
+ Store 4 - Query B
File 3 - Store 5 - Query A
+ Store 5 - Query B
The main question is: can this be done using BI Pub Enterprise? We using version 10.1.3.3.2
If it is, can you provide me with help on how to configure either/or the requests and template to accomplish this task?
I create an SR and Oracle Support does not have an answser and suggested that somebody in the Forum might help.
Thanks in advance,
Minh

I would like to have the following output:
File 1 - Store 2 - Query A + Store 2 - Query B
File 2 - Store 4 - Query A + Store 4 - Query B
File 3 - Store 5 - Query A + Store 5 - Query B
the bursting level should be give at
File 1 - Store 2 - Query A + Store 2 - Query B
so the tag in the xml has to be split by common to these three rows.
since the data is coming from the diff query, and the data is not going to be under single tag.
you cannot burst it using concatenated data source.
But you can do it, using the datatemplate, and link the query and get the data for each file under a single query,
select distinct store_name from all-stores
select * from query1 where store name = :store_name === 1st query
select * from query2 where store name = :store_name === 2nd query
define the datastructure the way you wanted,
the xml will contain something like this
<stores>
<store> </store> - for store 2
<store> </store> - for store 3
<store> </store> - for store 4
<store> </store> - for store 5
<stores>
now you can burst it at store level.

Cannot select multiple text items simultaneously

Since upgrading to the latest Pages, I can no longer select multiple letters/words by holding down command. I used to use this to edit multiple things (titles, for example) all at once (make bold, underlined, italicized, larger font, coloured, etc.). Now, however, I have to select each letter/word one at a time and edit them individually.
Is this just a bug or is there a new way of selecting multiple text characters simultaneously for editing?
Thanks!

There is no fix by any means.
Switching from Word to Pages v5 (any release) is like giving up oxygen for a vacuum. The time that you will expend searching for feature/functionality omissions in Pages v5 that you had in MS Word will just suck the life out of you.

Viewing multiple application windows simultaneously

Is it possible to view (float) multiple application windows simultaneously on a MacBook. For example, I am viewing a tutorial on Firefox while working on an image in Photoshop at the same time to try out the suggestions in the tutorial. I have to shift from one application to the other (command + tab) to go back and forth to view one or the other window. It would be great to be able to "float" a window from Firefox over the Photoshop window so I could read the tutorial while working in Photoshop. Right now, if I click on one application, it covers over the other application completely, requiring that I switch back and forth between the two. If an application window (Firefox tutorial) could float above the other one (Photoshop image), I could read the tutorial while still working on the Photoshop image.
Any suggestions greatly appreciated.
[email protected]

You could resize the windows so that both fit on the screen. Granted the screen size doesn't afford a lot of space for this so I have come up with 2 different methods for solving this problem. One is using Spaces. If application A is on one Space and B is on another, using a hot corner or keystroke can change from A to B quickly. My other solution was adding a 21.5" monitor to my work station giving me enough screen real estate for multiple window display.

Adhoc Query Requirement with Multiple Data Source

Hi All,
I have a Adhoc Query Requirement with Multiple Data Source. Is there any way to achive it. Other than Resultant set and bring into Model.
Thanks
SS

You can compare stuff in the EL, but I don't think this is what you need.
You can just use Java code in the backing bean class for all the business logic. You can use DAO classes for database access logic. Finally for displaying you can use the JSF tags such as h:outputText.
