Is anybody knows if there is custom firmware for sj4000 action cameras? I would like to use camera for timelapse video. There is a setting in Photo Mode that will take a snapshot every 5, 10 or 20 seconds from the time you press the Ok/Record button. But I need at least 60 seconds between the shots. Is anybody tries to hack bin file?
You might want to ask such questions here: http://video.stackexchange.com.
Anyways, as of now there is no custom firmware. Good news: You don't need one. My SJ4000 WiFi has an option "VideoLapse" in the official firmware, where you can choose 1,2,5,10,30 and 60 second intervals. This sounds like exactly what you want.
You may need to upgrade your firmware to make it work (I use G20150408V02). See http://www.sjcam.com/content/category/3-Firmware

Ok so this question is actually in two parts.
I coded a video filter for VLC and I would like to add a control to the Video Effects panel on the OS X UI. So far I've been able to link my plugin the the UI by hijacking one of the existing controls, but this isn't ideal.
Now, if I open up the Xcode project (I'm running Xcode 6.3.1) and try to open the VideoEffect.xib file, I get the following error:
I tried to google this but it sounds like the only alternative would be to play archaeologist and dig up an old copy of Xcode 3. Is there any other way to be able to open this file and edit it somehow? I tried to look at the XML code but if I started to change that I'd do more damage than good.
The second thing I'd like to do is sending back values from the effect module to the UI. At the moment (by hijacking one of the existing sliders), all I can do is read a value from the panel with
config_ChainParse(p_filter, FILTER_PREFIX, ppsz_filter_options, p_filter->p_cfg);
p_filter->p_sys->i_factor = var_CreateGetIntegerCommand(p_filter, FILTER_PREFIX "factor");
and then, inside the callback function:
p_sys->i_factor = VLC_CLIP( newval.i_int, 0, 255 );
However, I haven't been able to write back the value. I'd like the filter to set p_sys->i_factor to a random value at start. This works (using var_SetInteger()), but it isn't reflected in the position of the slider in the Video Effect panel. I suspect I need to hack a bit deeper for that. Any ideas?
Regarding your first question with the xib-file. Consider downloading and using our forthcoming 3.0 code from git://git.videolan.org/vlc.git - it allows editing of said file without Xcode 3.
Regarding your second question, why would you want your video filter to interfere with the UI? This is not how the architecture of VLC works and there is no correct way to do it at this point. You would need to edit the core to do another global variable callback to ask the UI to reload the presented filter configuration.
Perhaps, if you give details about what your filter does and what you want to achieve, we find a more supported way :)
I would like to know if it is possible to turn on the sony camera dsc-qx100 (or qx10) programmatically or if it is mandatory to turn it on manually ?
Also, is it possible to control the period before the camera turns off ?
My idea is to be able to switch between two cameras and it seems that if I don't connect to one for a while, it will turning off automatically (My test on playMemories app gives me four minutes before it turns off).
Is there a way to avoid that ?
Thanks
Controlling the power state is not possible programatically.
This is not controllable either.
(My test on playMemories app gives me four minutes before it turns
off). Is there a way to avoid that ?
On some models it is possible to programmatically change autoPowerOff time or to deactivate it. Look for setAutoPowerOff.
Is there a way to launch the camera app programmatically, from my own app? I know that you can use one of the tasks to launch it, allowing the user to take a single photo, but I want the user to be able to take multiple photos. The user could then just hit the back button to go back into the app. I could then track which ones were new by the date/time they were taken.
Jeffrey, you can use CameraCaptureTask class to launch the camera application. More info here
With this class you can take advantage of the camera, to take multiple pictures or something else. You need to manipulate the Completed event.
Hope it helps :)
There is great article here that guides you to the entire process of adding a camera to your app. It even allows you to take multiple images, rename them and saves them to the Camera Roll of your phone.
You could then use the DateTime class to add the date and time of the photo to the photo name (along with the name of your app), thus allowing you to better track the images taken.
Is there any way in which the usage of the camera of the iPad2 can be restricted only to my application? even if it is using i tunes.
could not find any code related to it. some code would be helpful.
There's no way to achieve this. I think it could be done with quite a bunch of hacking if you were developing for Cydia, but I'm not sure ever then. If the user quits your application or switches from it, the system will make the camera available to any other app requesting it.
I want to develop a screensaver-like app where the only way of getting back to the springboard is entering a code. Therefore I would need the Home Button action to be ignored, that is that when the user presses the button nothing happens..or something custom...instead of going back to the springboard and terminating the app.
Is this possible? does anybody know if apple will approve/reject this kind of app?
The answer to your question is, yes.
The answer to the question you meant to ask--can I ship an app through the iPhone store that has the home button disabled--is no.
If you are only publishing your app to jailbroken phones you can do it, but it will piss everyone off.
Edit 7 years later:
This is actually extremely possible now--there is a standard feature in the iPhone called "Guided Access". It's hidden under that "Accessibility" Link (With some other fairly cool stuff like flashing the LED whenever you get a call and allowing a Bluetooth keyboard to tab between controls)
It's called "Guided Access". You set a passcode, launch the app then triple-click the home button to start guided access.
It disables exit and allows you to designate regions of the screen you can't touch. You can also set a time limit (For kids playing which seems to be the reason a lot of people look up this question).
Tempted to edit the "Accepted answer" and throw this info in there, but that seems rude so I'll just hope people find this answer.
Annoyingly you also seem to be unable to shut off the phone--I suppose this is perfect for people who want their kids to play a game, but might not hit the original asker's problem of restricting access to a single app (I mean it WILL do that but it'll also prevent it from doing ANYTHING else).
Not with public APIS (and hopefully, not with private ones). Even if you manage it somehow, Apple will reject it for breaking UI guidelines. Moreover, even if they didn't, people could always use the iPhone's "Force Quit" equivalent to hard terminate your app.
Apple is not going to approve this type of app, they state pretty explicitly that you're app needs to respond appropriately to springboard telling the app to terminate both when things like phone calls come in and when memory warnings come in.
This is not possible with the current SDK, nor do I suspect it will ever be.
You might be able to get this behaviour via jailbreaking, but you won't be able to sell your app through iTunes, nor will Apple ever approve such an application.
You can do it like this
Install the following mobileconfig file
This will disable the home button once you launch the app

Apple won't allow it.
What if something emergency happens and you wan to dial an emergency phone number. You are putting the user at risk. The trade-off isn't worth it.
