If I want to transmit the audio infomation use my own format, how can I do?
In order to transmit the sound for secret, I want to change the default format by encrypting it.
Is it viable?
If it is viable, where can i find the correlative data?
Seems like there are two directions you could go in. First, you could extend the Processor class to add support for transcoding a new audio format, and then you'd be able to encode/decode it the same way normal audio works. Good luck figuring out how to do that, and good luck find any sort of helpful documentation.
The second idea, which is going to be more documented, is to developed a custom RTP payload. You could then use any audio format, and just encrypt the actual packetized data with whatever data encrpytion scheme you wanted. Most hosts would simply reject the RTP payload if they intercepted the stream, and even if they did receive it, they would have to be able to decrypt it before they could play it.
For more information about creating your own RTP payload type, take a look at:

I have an old project with AVCHD clips and I want to import the clips again with surround sound. How can I relink the project clips to the re-imported ones without doing the project from the begining?
I have a sony handicam and I imported the clips to iMovie and they lost quality and converted the audio to stereo. I want to import the project to final cut X and import the AVCHD in 1080p and surround sound and export the movie in bluray. Can I relink the clips without editing everything again?
thanks!Only photos taken with the iPad, copied onto it via the camera connection kit, or saved from emails/websites etc can be deleted directly on the iPad - either via the trashcan icon in the top right corner if viewing the photo in full screen, or via the icon of the box with the arrow coming out of it in thumbnail view.
Photos that were synced from a computer are deleted by moving/removing/de-selecting them from where they were synced from and then re-syncing. If you want to remove them all then normally you could just sync an empty folder (in terms of photos) to the iPad, but as you don't want to sync at the moment you can't do that.
You can reset the iPad back to factory settings and start from scratch with it : Settings > General > Reset > Erase All Content And Settings -
Hi, My region doesn't supports Passbook features. so i want to delete the passbook icon or hide it. How can i do it ? Kindly advice !!!
You cannot delete it but you could take it to your last home page. Tap on the icon until it shakes then move your finger on the icon to the right edge of your screen until the icon is half hidden and the iPhone will take the icon to the following page. If you have more than two pages, just keep repeating this move until the passbook icon is on the last page. While there, the icon will not take up space on the home screens you most frequestly use.

Call AppleCare and talk to someone in account security. Sounds like someone has managed to hijack your account.

Capturing on a Mac- can't turn off the sound (still want to record the audio)
How do you turn off audio output during capture on a mac but I still want to record the audio?
Easy on a PC, I click the "speaker" icon at lower right of Windows screen and bring up the audio mixer and just MUTE Premiere, then I can surf the web, watch online videos, listen to music etc, without hearing the capture audio. Assuming that's what you wish to do? Must be a similar option on Mac
Thanks

My video has no sound but i want to add the audio using premier pro
My video has no sound but i want to add the audio using premier pro.
when I want to import the file,it said:your video file has no audio.
But i want to add the sound to my video!!
Does anyone know how to solve this problem??So you have a video (.mov) that some how you got from Flash.
It has no sound on it.
Does the .mov import into Premiere?
If it does..you edit it in the timeline (sequence) and add audio to the audio track(s) before exporting it. -
Airport dont transmit the audio signal
My Airport express is connected in the network as a "slave", so it dont distribute ip addresses. In this mode it dont transmit the audio signal to my audio system.
If I change the configuratioin and it does distribute ip addresses, it also transmit the audio signal to the aduio system.
Is there a solution for this bug?Not sure what you mean by "slave." I assume that you mean that you configured the AirPort Express Base Station (AX) to join an existing wireless network as a wireless client ... correct?
If that is so, then streaming from iTunes would first travel to the other wireless router, and then, to the AX before it goes to the audio system. -

How can i detach the video from a clip so i can only use the audio when using imovie?
how can i detach the video from a clip so i can only use the audio when using imovie?
First, go to iMovie/Preferences and enable the Advanced Tools.
Import the video clip into an iMovie Event. When you get ready to use it in an iMovie Project, select the clip in the Event and drag & drop it on top of a video or photo clip in the project at the place where you want it to begin. When the pop-up menu appears, choose Audio Only. -
I have a new MAC MINI and I want to install a second monitor. I have one connected to the HDMI and it works. I can't get a signal to the other one. It is connected from the thunderbolt to its HDMI port. How can I make it work?
Could be a bad cable or bad Thunderbolt port.

You can also make an appointment at the Genius Bar of an Apple store.
