I am creating a web app that combines AFrame for augmented reality and Resonance Audio for spatial audio. Resonance uses the Web Audio api.
On iOS, the audio becomes progressively more crackly and distorted like a feedback loop, until it stops completely. I have tested this on an iPhone 6s running iOS 14.6 within about 10 seconds, and also occurs on an iPhone 12 mini on iOS 14.6 after a few minutes.
The issue does not occur on a Macbook Air (Early 2014, safari 14.0.1, macOS 10.14.6), windows 10 laptop or xiaomi phone running Chrome.
I would understand consistant glitching due to performance, but not gradually increasing.
Thanks for your time!
We saw similar behaviour in Safari on Mac when we were running animations with requestAudioFrame. We were starting more and more and not properly clearing the old ones. This caused the audio input to crackle more and more. Once we cleaned up the animations the audio problems went away.
We are capturing video from iOS devices and processing it using OpenGL but are encountering a FPS difference between the devices when trying to set them at their maximum rate.
The iPhone 6S and iPad Pro FaceTime cameras are maxing at 60 fps.
The 7+ and iPhone X however are maxing at 30 fps.
It seems unusual that the FPS would decrease with later versions of Apple's hardware. We are trying to figure out if this is a software issue or simply the technical specifications for the frame rate for the FaceTime camera.
We looked on Apple's technical specifications page but the frame rates of the FaceTime cameras aren't listed (though the rear cameras are.) For example:
https://www.apple.com/iphone-6s/specs/
https://www.apple.com/iphone-x/specs/
What are the FPS of the FaceTime Camera for the iPhone 6S vs 7+ vs X vs iPad Pro?
It looks like you’re correct. According to Apple’s iOS Device Compatibility Reference...
iPhone 6s series front camera does up to 60 FPS (all formats)
iPhone 7 series front camera does up to 30 FPS
iPhone 8 series / X front camera does up to 60 FPS, but only in binned formats (so you probably need to set the device’s activeFormat, not just choose a preset)
iPad Pro info is also in the tables at that link.
I developed an iOS application with live video streaming. I fixed the audio sample rate to 8k. Audio works fine up to iPhone6 devices, but when i stream video in 6s and 6s plus audio part is not working. How can i fixed this issue? I tried in different blogs and found that in iPhone 6s sample rate is locked in 48k. How can i manually down sample? Because the library that i used for live streaming works only in 8k. Please help me on these
You can do your own sample rate conversion by low-pass filtering the data to a frequency below 4 kHz, and then taking every 6th sample (to convert 48 ksps samples to 8 ksps samples).
I'm facing an issue in broadcasting video from one iPhone to another iPhone.
The issue is when I view the friend's live video in my iPhone, the frame per second(fps) is very low(it is 12fps). Video quality and audio is looking fine but the only problem is fps.
I don't know where I need to config/change the code to convert from variable fps to constant fps. Also to increase the fps as **24/30**.
The resolution I used for broadcasting
RESOLUTION_VGA, // 480x640px (landscape) & 640x480px (portrait)
I'm using following libraries for streaming
MediaLibiOS - link
Ffmpeg-2.2.1
CommLibiOS
libx264-r2409
Wowza is a Media Server and iOS target version is 7.0
Please help !
Thanks in advance.
I'm developing an iPad app that can employ an external monitor. When I plug my iPad 3 into my external monitor, I get back a list of resolutions from the external UIScreen object that includes 1920x1080.
When I do the same with my iPad mini, the max resolution I get back is 1600x900.
This would make me think the iPad mini doesn't support full HD external video, but the Apple specs say this:
Video mirroring and video out support: Up to 1080p through Lightning
Digital AV Adapter and Lightning to VGA Adapter (adapters sold
separately)
...which seems pretty unambiguous that it should support full HD.
Does anyone know what's going on here?
Thanks!
The iPad mini does not HAVE the resolution for 1080p (it has 1024x768 screen resolution while 1080p is 1920x1080 as you mentioned), hence, mirroring does not make sense.
Video playback, on the other hand, should work.
TV resolution can be set in Settings>General>TV Out.
The max resolution shown in that menu is your iPhone or iPad's screen resolution.
