How to record a video in iOS
(4 answers)
Closed 9 years ago.
I am new to the iPhone development. I would like to know how to capture the video in Xcode....
I know how to take still images in iPhone using Xcode but dont know how to capture video. Can anybody help me??? Any little help will be appreciated greatly. Thanks in advance...

I'm pretty sure there's no direct way to capture video from a running application in the way that you can grab a screenshot in Xcode.
As such, you might want to use some screen recording software in conjunction with the iPhone Simulator.

I hope you can help me with this. I have assigned a script to multiple drawings (as buttons) in Google Sheets and is running perfectly on PC. When I try it on my phone, the script does not run, but rather gives an option to edit. What should I do, please?
The Google Sheets mobile apps doesn't support using drawings as buttons (assign a Google Apps Script function).
Regarding what you should do, you should look for other ways to call your functions from a mobile apps like using a edit trigger.

What is the specifications for a-frame 360 vr video?

I'm using a-frame for a web-vr project, and I'm planning to use 3d environment I made in Cinema 4d.
But there're not much information about the specification for the video other than the format.
I already tried to make the resolution same as the sample 360 video(3168x1584) for a-frame, but it also didn't work and I want to know if there's any information about this.
Plz let me know if anyone knows any doc about this. I already tried but I couldn't find any clue yet :'(
use .mp4 format.
Best if resolution is a power of 2. ie
1024 x 2048 (or any power of 2).

zbar sdk not working on iphone simulator by using camera simulator
I want to test my barcode scanner using iPhone Camera.
I'm using ZBar SDK for my barcode scanning.
I have a scan button for this.When I click on Scan button,its showing me the message,"Camera simulation, tap and hold with two finger to select image".When I'm doing this,its showing "No photo" in another view.
Could any one plaese tell me how can I select an barcode image and scan it using simulater?
Thanks.
Do you have any images in the simulator to test? If not, images can be added to the simulators photo library two ways.
Drag and drop an image from Finder into the simulator. It will open in Safari and you can press and hold the image and an action sheet will pop up asking you to save.
Go to Safari directly on the simulator, navigate to the image you want, and save it the same way as in step 1.

The scroll lock button seems to be a reminder of the good old green terminal days. Does anyone still use it? Should the 101 button keyboard become the 100 button keyboard?
In Excel, if you turn on scroll lock, using the arrow keys scrolls the spread sheet instead of changing the cell the cursor is in.
I use it all the time on Unix terminals. It is quite handy when something catches my eye when I'm tailing a log file.
In many KVM situations, double-hitting scroll lock with bring up the machine selection screen.
Microsoft Excel uses Scroll Lock to allow you to scroll the spreadsheet around with the arrow keys without changing the active/selected cell -- in line with the Scroll Lock key's original intent.
In Microsoft Excel, Scroll Lock allows you to scroll a spreadsheet with the arrow keys without moving the active cell pointer from the currently highlighted cell. In Quattro Pro, another spreadsheet program, Scroll Lock works in a similar manner, although in contrast to Excel it's not possible to scroll the active cell pointer completely off the screen.
Other programs use Scroll Lock for special functions.
Scroll lock (at least the LED for it, anyways) is used along with the caps lock and num lock LED's to provide diagnostic error codes when troubleshooting hardware issues on Dell laptops. This is quite useful when troubleshooting display problems that might prevent diagnostic messages from being read off the screen.
It looks mostly dead:

I don't remember the last time I used it...
If you happen to have some legacy MS-DOS games around, it might be useful ;-)
One of the visualization plugins for Winamp (A media player) uses scroll lock to prevent the visualization from rotating visualizations every x seconds
In Synergy you can lock your mouse to the current screen. Very helpful when you want to share a mouse with a PC on the other side of the room.
Well, that's yet another key to be used with AutoHotkey... (or other keyboard shortcut managers).
Since it is connected to the LED, some clever folks have added code to make it flash (e.g. scroll lock on/off/on/off) at a given interval as a notification for new email messages (or similar)
This can be "cool" if you have a laptop, that is closed (or the screen is sleeping)... you just see if the light is blinking.
I use it all the time, with the purpose for which it was made. For a variety of things.
