How to stop recording in BigBlueButton. I can only see the Pause recording button. Have checked the bigbluebutton.properties file and couldn't find any relevant stuff on that too. Any help is highly appreciated.
You can't. BBB always records, if recording is globally enabled and activated in the room settings.
The record/pause button simply marks the timestamps so that BBB can cut the recording during post-processing when the conference is finished.

I am using AVAudioRecorder for recording sound in my ios app. I want that if user moves the UISlider object to 2 seconds and press Record button then after saving the recording file and playing it, user should hear the recording after a pause of 2 seconds. How can I achieve this functionality? Can anyone please help?
Best Regards
You can add 2 second silence (please consider slider value is 2) to your Audio file starting section
To do this please go through this link
The below links also may help you to achieve the goal.

My initial issue was as described in the title there. When I was recording from the mic, sound effects were playing at the same time even if the device was in mute mode (i.e., had the mute button physically switched on).
I since found this thread, which totally worked. the mute button now works correctly, and no sounds are played in the app while the mic is recording...
Unfortunately, the mic has now stopped recording!
It seems like I can have one or the other, but not both. Can anyone confirm if I can have the device on mute and record from the mic at the same time? And if so, how?
Thank you so much in advance,
Stew
UPDATE : I'm fairly certain that this isn't possible, and I'm basing this on the fact that the mute switch also doesn't work in Garage Band (Another app which requires simultanious playback and recording).
To try it yourself, simply load up Garage Band, play some music, and then note that the mute switch doesn't work.
I'm leaving this open in case anyone does come up with a solution, but I won't be offended if it's closed or deleted.
In the default Voice Recording app on the iPhone, starting to record turns the iPhone header red and starts a timer. Is this something that we can reproduce in an app, or perhaps this is behavior that always happens when recording sound?
Take a look at MTStatusBarOverlay on GitHub.
Also, try this one....
Tweetbot-Like Alert Panels (Blog), and the repository is MKInfoPanelDemo at Github.
I have an alarm clock app which works on a timer. When the alarm is meant to go off and the screen is switched off, it should start playing audio from AVAudioPlayer, but it doesn't. Then when i turn the screen back on, i can see that the rest of the code fired as expected (a stop button is now on the screen). How do i get the AVAudioPlayer to play when the screen is turned off?
Is there any way for me to detect that the screen is turned off?
#zoul is correct that using the default audio session category will result in sound form your app being disabled when the user locks the screen. See the Audio Session Programming Guide for direction on which audio session category you should choose.
However, even once your audio session category is set correctly, you'll have another issue to tackle. When the screen is switched off, your application gets suspended per Apple's documentation here: Executing Code in the Background. This means that when the user locks their phone or switches to a different app, your app will stop running and stay in a freeze-dried (task-suspended) state until the user activates your app again. At that point, your app resumes execution as if nothing happened. That's why it appears that your app has continued to function when you unlock the screen.
For alarm behavior, you'll probably want to schedule the delivery of a local notification. A local notification will ensure that the system provides your alert to the user at the time you request, and allows the user to activate your app. See Scheduling the Delivery of Local Notifications for details on how to accomplish this.
Maybe you have the wrong audio category? See the documentation for AVAudioSession, especially the audio category settings.
I want a functionality in which i want to detect if my device is being shaked.The problem is i can detect the shake with didAccelerate method of UIAcceleratorDelegate , but i dont know how to detect if the device is still shaking. I want to play an audio file when the user shakes the device for first time,i have to check if the user is still shaking the device while playing the 1st audio file,if it is still being shaked, then i have to play another file.
See the sample project GLPaint from Apple which was found by visiting http://developer.apple.com/iphone and entering "shake" in the search box. Developer account not required.
You might consider writing a Method that runs in a separate thread that polls wether your device is being shaken every now and then and fire events that you handle somewhere else in your code (or instead of that, handle whatever you want to handle within the threads context itself, even tough i would not recommend doing that).
You just have to make sure, that your "shake-detektor"-thread exits at some point in time, you probably want to do that when the second audio file stopped playing. So your loop could test on that condition.
Hope I could help a bit.
