Have a Question regarding RTP Manager?
Please SomeBody Tell me!
I am Creating an RTP Player for Each New Receive Stream using RTP Manager.
I have some question::
What is the role of SourceDescription in initialize(SessionAddress[] local,Source
Descritpion[] source,double d,double d,EncryptionInfo encry)?
Is there any role of AddTarget(SessionAddress dest) nedeed in my application?
What is the role of SourceDescription in initialize(SessionAddress[] local,Source
Descritpion[] source,double d,double d,EncryptionInfo encry)?From the API:
sourceDescription - An array of SourceDescription objects containing information to send in RTCP SDES packets for the local participant. This information can be changed by calling setSourceDescription() on the local Participant object.
So, source description is used to tell the remote participants things about the sender.
Is there any role of AddTarget(SessionAddress dest) nedeed in my application?AddTarget tells the RTPManager where to send the RTP streams, so if you expect anyone to receive your streams, you damned well better add them as a target.

I have some questions regarding setting up a software RAID 0 on a Mac Pro
I have some questions regarding setting up a software RAID 0 on a Mac pro (early 2009).
These questions might seem stupid to many of you, but, as my last, in fact my one and only, computer before the Mac Pro was a IICX/4/80 running System 7.5, I am a complete novice regarding this particular matter.
A few days ago I installed a WD3000HLFS VelociRaptor 300GB in bay 1, and moved the original 640GB HD to bay 2. I now have 2 bootable internal drives, and currently I am using the VR300 as my startup disk. Instead of cloning from the original drive, I have reinstalled the Mac OS, and all my applications & software onto the VR300. Everything is backed up onto a WD SE II 2TB external drive, using Time Machine. The original 640GB has an eDrive partition, which was created some time ago using TechTool Pro 5.
The system will be used primarily for photo editing, digital imaging, and to produce colour prints up to A2 size. Some of the image files, from scanned imports of film negatives & transparencies, will be 40MB or larger. Next year I hope to buy a high resolution full frame digital SLR, which will also generate large files.
Currently I am using Apple's bundled iPhoto, Aperture 2, Photoshop Elements 8, Silverfast Ai, ColorMunki Photo, EZcolor and other applications/software. I will also be using Photoshop CS5, when it becomes available, and I will probably change over to Lightroom 3, which is currently in Beta, because I have had problems with Aperture, which, until recent upgrades (HD, RAM & graphics card) to my system, would not even load images for print. All I had was a blank preview page, and a constant, frozen "loading" message - the symbol underneath remained static, instead of revolving!
It is now possible to print images from within Aperture 2, but I am not happy with the colour fidelity, whereas it is possible to produce excellent, natural colour prints using its "minnow" sibling, iPhoto!
My intention is to buy another 3 VR300s to form a 4 drive Raid 0 array for optimum performance, and to store the original 640GB drive as an emergency bootable back-up. I would have ordered the additional VR300s already, but for the fact that there appears to have been a run on them, and currently they are out of stock at all, but the more expensive, UK resellers.
I should be most grateful to receive advice regarding the following questions:
QUESTION 1:
I have had a look at the RAID setting up facility in Disk Utility and it states: "To create a RAID set, drag disks or partitions into the list below".
If I install another 3 VR300s, can I drag all 4 of them into the "list below" box, without any risk of losing everything I have already installed on the existing VR300?
Or would I have to reinstall the OS, applications and software again?
I mention this, because one of the applications, Personal accountz, has a label on its CD wallet stating that the Licence Key can only be used once, and I have already used it when I installed it on the existing VR300.
QUESTION 2:
I understand that the failure of just one drive will result in all the data in a Raid 0 array being lost.
Does this mean that I would not be able to boot up from the 4 drive array in that scenario?
Even so, it would be worth the risk to gain the optimum performance provide by Raid 0 over the other RAID setup options, and, in addition to the SE II, I will probably back up all my image files onto a portable drive as an additional precaution.
QUESTION 3:
Is it possible to create an eDrive partition, using TechTool Pro 5, on the VR300 in bay !?
Or would this not be of any use anyway, in the event of a single drive failure?
QUESTION 4:
Would there be a significant increase in performance using a 4 x VR300 drive RAID 0 array, compared to only 2 or 3 drives?
QUESTION 5:
If I used a 3 x VR300 RAID 0 array, and installed either a cloned VR300 or the original 640GB HD in bay 4, and I left the Startup Disk in System Preferences unlocked, would the system boot up automatically from the 4th. drive in the event of a single drive failure in the 3 drive RAID 0 array which had been selected for startup?
Apologies if these seem stupid questions, but I am trying to determine the best option without foregoing optimum performance.Well said.
Steps to set up RAID
Setting up a RAID array in Mac OS X is part of the installation process. This procedure assumes that you have already installed Mac OS 10.1 and the hard drive subsystem (two hard drives and a PCI controller card, for example) that RAID will be implemented on. Follow these steps:
1. Open Disk Utility (/Applications/Utilities).
2. When the disks appear in the pane on the left, select the disks you wish to be in the array and drag them to the disk panel.
3. Choose Stripe or Mirror from the RAID Scheme pop-up menu.
4. Name the RAID set.
5. Choose a volume format. The size of the array will be automatically determined based on what you selected.
6. Click Create.
Recovering from a hard drive failure on a mirrored array
1. Open Disk Utility in (/Applications/Utilities).
2. Click the RAID tab. If an issue has occurred, a dialog box will appear that describes it.
3. If an issue with the disk is indicated, click Rebuild.
4. If Rebuild does not work, shut down the computer and replace the damaged hard disk.
5. Repeat steps 1 and 2.
6. Drag the icon of the new disk on top of that of the removed disk.
7. Click Rebuild.

Drive A + B = VOLUME ONE
Drive C + D = VOLUME TWO
What you put on those volumes is of course up to you and easy to do.
A system really only needs to be backed up "as needed" like before you add or update or install anything.
/Users can be backed up hourly, daily, weekly schedule
Media files as needed.
Things that hurt performance:
Page outs
Spotlight - disable this for boot drive and 'scratch'
SCRATCH: Temporary space; erased between projects and steps.

(normally I'd link to Wikipedia but I can't load right now)
Disk drives are the slowest component, so tackling that has always made sense. Easy way to make a difference. More RAM only if it will be of value and used. Same with more/faster processors, or graphic card.

I have a question regarding my txt/alert tones. I recently updated my iPhone 5's software without first backing it up on iCloud or my computer (oops). After my phone finished updating, i lost the new ringtones and txt/alert tones i had bought. I connected my iPhone to my computer and sync'd it hoping that it could download my purchases from the itunes store and then put them back on to my phone but no such luck. When i look at my iphone on my computer and look at tones, they do not show up at all. However, if i click on the "On This iPhone" tab and click on "Tones" the deleted ringtones and altert tones show up...they are just grey'd out and have a dotted circle to the left of them. I also tried to go to the iTunes store on my phone and redownload them and it tells me that i have already purchased this ringtone and asks me if i want to buy it again. I press Cancel. I know when i do that with music it would usually let me redownload the song without buying it again but it wont let me with the ringtones...so how do i get them back? any help would be greatly appreicated
Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M. -
I have 2 questions regarding the iphone 5. 1 How do i get my yahoo mail set up. I tried the setting it up as both a yahoo mail and other mail. 2. I seem to have lost my notes on my iphone 5 but I have them on my ipad. How can I use cloud to sync my notes?
I will address your second question.
First, make sure your iPhone and iPad have absolutely identical Apple IDs. If they do, use that Apple ID in Settings > iCloud on your iPhone to select the "Notes" option. Lo and behold, all your iCloud notes should appear on your iPhone. -

I worked long and hard on the project and when I go click the share feature on iMovie all the noral options pop up and when I actually click where I want to share it to nothing at all happens. If you know what is wrong/ what I am doing wrong please let me know.
Thank you.
PS: I am using iMovie 10.0.6./*line 957 error */

I have a question regarding emails being marked as unread when syncing with an exchange account.
I have a question regarding emails being marked as unread when syncing with an exchange account.
In the evening I can see I have 10 unread emails on my exchange account. I leave them unread. The following day, at work, I view and read all my mails from today and yesterday, so that I have NO unread messages. When I then sync my iphone it marks only the mails from today as read but, leaves all the mails from yesterday marked unread. Only solution so far is for me to go through the mails on my iphone one at a time for them to be marked as read.
My mail account is set to sync 1 month back.
I have had this problem on all the iphones I have had.
I currently have an iPhone 5 and my software is up to date.
What am I doing wrong?Hey kabsl,
Thanks for the post.
What type of email account is attached to your BlackBerry Z10? (POP3, IMAP, Exchange). Also have you tried removing and re-adding the email account to test?
Is this email account only setup on one computer or several computer?
I look forward to your reply.
Cheers.

I have just got my iPad2 and am very pleased with it. I have a question regarding the monthly (recommended) battery full charge. Should I let the battery completely die down to nothing at all before I plug in to recharge or would this complete drain be bad for my iPad?
It's not bad for it - on this page www.apple.com/batteries/ipad.html it says :
For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down). -

I would like to use Turbotax for mac. I am a new user and just bought my Imac desktop a few weeks ago. Can I purchase and download the software from Apple? I do not have an optical drive so I need to use the download method.
Thank you for your reply. I may not have phrased my question correctly but what I was ondering is whether Apple sells this software download or whether it is only available thru Intuit. I have tried severl other vendors (Micro Center, Costco, Bjs Wholesale) and none of them have it available for download. Must I go thru Intuit only if I use this method?

I have several questions regarding Final Cut Pro X
I went to the APP Store to check out FCPX and accidentally downloaded it (v. 10.0.3)
I didn't freak out too badly as I had planned to buy it eventually, but One Click?
Anyhow, the deed is done.
Since the application was downloaded, how do I make a backup copy? I mean, I could
burn the application to a DVD, but usually an Installer puts files in different folders in
various locations, and I would have no way of knowing where they all are. What have
the rest of you done?
The first thing I ran into upon opening FCPX was a message saying "The selected SAN location
is already in use." At this point I didn't even know what a SAN location was. It somehow decided
it wanted to use my 3TB Seagate drive I'm using as a TimeMachine Backup drive. I think I managed
to delete the SAN location.
But it is putting Final Cut Events on a drive I don't want to use for that, and the drive I have designated
for video does not appear within FCPX as a choice. I rebooted and it showed up for an instant and then
disappeared.
I had FCP many years ago and you used to specify locations for saving files. As I said, I have a drive
reserved for Video and it doesn't show up within FCPX.
I have old versions of Motion and LiveType that came with FCP before. Do they work with this version?
So far I'm struggling with this. I have AppleCare. Do they support this application?
Help please.
jamesTom, thanks for your Answer!
I'll just burn the FCPX app to a DVD and hope that's all the files it needs.
As for my drive, it is formatted just the same as all my other externals.
I've got a bunch of them dedicated to different types of material (photo, music, audio samples, video, etc.)
The fact that that drive shows up in FCPX and then disappears is troubling.
I don't know enough yet to know whether something is wrong or it's user error. -
I have a question regarding Notebooks & Netbooks - do they have an ACPI-complian BIOS?
Folks;
I am qualifying hardware for a remote monitoring application we are building. We want to use a laptop as the PC in this monitoring system both because we need a PC, and also because we want to use the laptop's own keyboard & display for on-site setup & service.
I have a few questions concerning how to configure one of your laptops -or whichever laptops would be suitable - to make sure that it will boot into windows properly after AC power is interrupted.
My expectation is that the program running on the laptop will monitor the AC power, and battery level. After AC power is lost, it will monitor the battery until some level is reached, and then shut down windows.
When AC power is restored, I need the laptop to boot & run windows again. When windows starts, my monitoring program will also be started.
Do you have a laptop that can do this? If so, which ones?
An additional issue would be: what happens if AC power is restored after the window's shutdown has been started, but is not yet completed? Would the system shutdown, and reboot & run windows properly?
Thank you for your attention.
Sincerely;
Patrick McHargueA screen capture showing your document structure and problem in Photoshop may help get and answer.

I have a question regarding the iPod Touch and iPhone batteries.
Hello,
I started asking myself questions lately about my iPod Touch 5th generation battery. A few months ago, when a friend of mine asked me to plug her iPhone 5S in the wall (the battery depleted), I noticed that her phone was at 1% of battery power. Then I compared my iPod Touch battery with her phone's battery, and discovered that my iPod Touch stops working when the battery is close to 10% battery power. This is concerning to me because I feel like I only have about 85-90% of battery power available when I use my iPod Touch, while my friend has over 99% of battery available. It's a huge gap, I can't use this 10% that I wish i had. I'm wondering why iPods can't stop functioning when the battery is close to 1% instead of 10%? Can you imagine not being able to use 10% of your battery! And it was like this since iOS 6.1.3. My iPod Touch would shut down automatically when the battery would be depleted, but in reality, it still had 10, maybe 15% left. Why is that?
Thank you.Hey Lil'fighter, First, stop comparing an iPod with an iPhone. They may look a like on the outside, share the same iOS, and some of the components, but that is as far as it goes! The biggest reason your friends iPhone out last the iPod is a bigger battery, greater capacity. Secondly, the phone is configured a bit differently and uses power a little more effectively. Third, it is impossible to completely drain the battery in either device. A safety circuit prevents you from doing that. With Li-ion batteries if you completely drain one, it will de-ionize and become useless; never charge again. I suspect the threshold is set higher for an iPod then on an iPhone. But if you feel your iPod is not performing as it should, and a reset or restore does not improve function, then by all means take it to Apple and have it evaluated. Hope this helps. Cheers.
