Anyone knows how to hide Recording Indicator in ios14?
I’m writing a camera app, so is very clear that when the app is in use both camera and microphone are in use!
You can't. That's the whole purpose of the indicators: that the developer can't hide that their app is recording audio or video. Even the stock Camera app doesn't do that.

When I take picture from camera using UIImagePicker, background music (from ipod app, pandora app) stops. It's not happening for facebook app. Is there a separate delegate for this? Please help
This might be due to your Audio Session policy. Taking a picture makes a "click" noise. Perhaps this is causing all other sound to be stopped because of your Audio Session.
How can I allow iOS device to dim screen and auto-lock the device while playing a video with AVFoundation. Playing a video with AVPlayer disable screen auto-lock by default. Is there anyway to re-enable it without pausing the video play.
why you want screen to go idle while playing video? The real answer is it can't be done. Following are just work arounds with serious downsides.
The only method apple allows us to use is
[UIApplication sharedApplication].idleTimerDisabled
You can dim screen programmatically by using a UIView with color black and slowly changing it alpha property to create the illusion of screen going idle.
I worked on the application where we used AVPlayer to display video backgrounds in application. Our solution was to stop video after some idle time. I mean implementing idle timer on our side. And then send message to all background players to stop them. It's the only good workaround I know.
In my iPhone app, I am using the UIImagePickerController with source type UIImagePickerControllerSourceTypeCamera. When the user takes a picture, the phone plays the familiar camera shutter sound. How can I replace this with my own custom sound? I know it's possible because I've seen other apps from the App Store do it (e.g. Red Laser).
I am quite certain it's not possible. AFAIK, Red Laser doesn't actually take a "normal" picture but uses UIGetScreenImage() (undocumented but nevertheless allowed for App Store apps) to make a screenshot of the live video feed. Since the OS does not play sound on this occasion, they are free to play their own sound.
Edit for clarification: As of OS 3.1, you are free to substitute the standard camera interface with your own controls. So you could place your own shutter button on the screen and play your own sound when the user taps it, but AFAIK there is now way to get rid of the OS's standard shutter sound.
AFAIK the standard camera shutter sound cannot be changed via SDK.
This answer supports that. You can replace your own sound by switching sound files, but not in an app.
Some answers such as this one suggest using AVCapture, but this method takes video screenshots, which reduces the image quality. I
t appears that you can't change the shutter sound because you could make it a silent sound, and capturing images covertly is against the App Store policy. See this answer.
TLDR:
The only way to change the shutter sound is to use a video screen grab.

What I have to do is play a video file in mp4 format. If the device is in portrait mode then it should display the video, but when the user changes the device to landscape mode it should just show an image.
But currently when I play a video, it takes control of the whole app; I can't send a notification to any event, and control only returns to my code after playing the full length video.
How can we can access another things while we are playing the video on the device?
Thanks for the help

Try spawning a new thread and then call the code to play the video from the new thread. This should leave the rest of your code free to do what it needs, unless I am misunderstanding your question.
You can use the shouldAutorotateToInterfaceOrientation: to check what orientation the device is in, and then do the logic in there.
Eg, if the orientation is portrait, start the MPMoviePlayerController playing the movie, then when the orientation changes to landscape, dismiss the moviePlayer.
