So after a lot of searching I was able to find the code block that allows background audio to play while at the same time recording video. I have pasted said code block below.
fileprivate func setBackgroundAudioPreference() {
guard allowBackgroundAudio == true else {
return
}
guard audioEnabled == true else {
return
}
do{
if #available(iOS 10.0, *) {
try AVAudioSession.sharedInstance().setCategory(.playAndRecord, mode: .default, options: [.mixWithOthers, .allowBluetooth, .allowAirPlay, .allowBluetoothA2DP])
} else {
let options: [AVAudioSession.CategoryOptions] = [.mixWithOthers, .allowBluetooth]
let category = AVAudioSession.Category.playAndRecord
let selector = NSSelectorFromString("setCategory:withOptions:error:")
AVAudioSession.sharedInstance().perform(selector, with: category, with: options)
}
try AVAudioSession.sharedInstance().setActive(true)
session.automaticallyConfiguresApplicationAudioSession = false
}
catch {
print("[SwiftyCam]: Failed to set background audio preference")
}
}
However, I have one small issue. For some reason when the camera loads the background Audio volume is reduced. When I record a video with instagram the audio doesn't get reduced and it still records is there any way I can change my current code block to not lower the volume while recoding with video?
I read the documentation and apparently .duckOthers option should be the only option that reduces the volume. But this one does as well
Okay so I found the answer after diving further into some of the documentation.
Updated code posted below. All you have to do is set the .defaultToSpeaker option
fileprivate func setBackgroundAudioPreference() {
guard allowBackgroundAudio == true else {
return
}
guard audioEnabled == true else {
return
}
do{
if #available(iOS 10.0, *) {
try AVAudioSession.sharedInstance().setCategory(.playAndRecord, mode: .default, options: [.mixWithOthers, .allowBluetooth, .allowAirPlay, .allowBluetoothA2DP,.defaultToSpeaker])
} else {
let options: [AVAudioSession.CategoryOptions] = [.mixWithOthers, .allowBluetooth]
let category = AVAudioSession.Category.playAndRecord
let selector = NSSelectorFromString("setCategory:withOptions:error:")
AVAudioSession.sharedInstance().perform(selector, with: category, with: options)
}
try AVAudioSession.sharedInstance().setActive(true)
session.automaticallyConfiguresApplicationAudioSession = false
}
catch {
print("[SwiftyCam]: Failed to set background audio preference")
}
}
