What is the recommended FFMPEG settings for encoding a video which can play on all apple devices, old and new. I would like the format to be in mp4 so that the video file is also compatible to android, windows (phone / pc) and linux. These are the current settings I have used and they do not work on iOS, These settings work great on Windows and Android but not on iOS. ffmpeg -i input_video.mp4 -c:v libx264 -crf 23 -profile:v baseline -level 3.0 -pix_fmt yuv420p -c:a aac -ac 2 -b:a 128k -movflags faststart -o output_video.mp4 I'm new to developing for iPhone/iOS. so thanks in advance.

I updated my iPhone 11 Pro to iOS 15 beta and I think it is causing problems with my personal hotspot. I live in a rural area with almost no options for decent, home WiFi; my options are DSL and satelite. For the last 8-9 months, I've used my iPhone's hotspot for gaming, streaming, and pretty much everything else. I've had no issues and it has saved me a ton of money! However, the day I updated my phone to iOS 15 beta, any non-Apple device I connect my hotspot to will not load anything... For example, my PlayStation 5 is able to download software updates and game updates with pretty quick speeds when connected to my hotspot, but it will not allow me to play any games online or pull up any streaming services. It says the connection is too weak. The same thing applies to my Roku that's plugged into my TV in the bedroom. Both of these worked really well before updating. When I connect my iPad to my hotspot, everything loads incredibly fast. I've contacted my phone service provider and they've assured me that my cell service is not the issue. Has anyone else experienced this and is there anyway to fix it? Thank you!

Hello, (sorry for long log attached within) There has been concern (long story) that my secondary apple ID, phone was somehow linked or registered within an app developer or anything other then default and looking for clarification. This log is directly from the phone/apple ID and the log was generated with a credible source. The apple ID/phone should not be associated with anything and no APP dev account should be associated within the log. Additionally my phone/apple ID that this log is associated with I am wondering if someone can tell me if there is anything to support or speculate that the phone is being shared or bundled in some fashion of any kind to share data, location, apps, or if there is anything such as coding of any kind that is anything other then what your standard phone would look like right out of the box with default settings. It's my suspicion that the apple id/phone log would support the issues that's been present of many issues that can be explained later. Any help would be greatly [appreciated.]( Log of Apple ID/phone in question - https://developer.apple.com/forums/content/attachment/7c971c69-4a7c-43a4-b5e4-42e9e180d161 )

Dear, I have a question regarding the approval of the app in the store. I upload the app and right after that it was put under review, but it's been 3 weeks and still under review. Is this time normal? Note: I have other apps and on average it took 4 days to get an answer. Thanks.

My mom accidentally locked her self from her Iphone 12, she wasn't aware what the consequence would be if she tired many time to do this. Long story short she has been in mourning for a few weeks now with severe depression. All of her most recent memories of her youngest child who passed away are now gone, Apple support has told us there is no way to unlock the phone without a hard reset. This is a terrible feature especially if most people are unaware of it, I have had an Iphone for several years and am just now finding out also. She never backed up anything on her iCloud because she was unaware of the service as well, note she is in her late 40's and knows nothing about tech. Im now put in a position where I have to figure out how to break the news to my mom that all her most recent memories of her 16 year old deceased child is gone. Is there really no way we can recover the photos?

Hi Everybody, I am facing screen flickering issue in my iphone 12( black screen turns out to be greenish) and I have noticed this thing few months back when i turned on my Dark mode + Night Shift + Low Power mode together). For confirmation i have asked my other friends who owned iphone 12 but they don’t have any issues. And also I have checked this on my iphone 13 there also this issue doesn’t exist. Apple team said they are looking into this matter and will fix in future updates. And I have done research on Google and this issue was reported back in 2020-2021 already but till then apple didn't resolved this issue and it's totally manufacturing issue. What should I do ? Can anybody recommend? Here are few links of reported issues. https://discussions.apple.com/thread/253137364 https://www.firstpost.com/tech/news-analysis/iphone-12-users-report-green-tint-and-flickering-issue-with-display-apple-might-fix-the-problem-in-future-ios-update-9034151.html

I want to fetch the certificate chain related to the secret key (used for encrypting data in the keychain) stored inside the secure enclave of any iPhone device. This certificate chain will be used to verify that the user is connected using a valid iPhone device.

I use PHPhotoLibrary in iOS to save JPG files to the camera roll. There is a difference in the date and time displayed in the "Photos" app depending on whether the 24-hour display setting in iOS is set to On or Off when saving. When saving with "24-hour display: Off", the date and time in the Exif of the JGP file is displayed. When saved with "24 Hour Display: On", the date and time when the file was saved is displayed. JPG files are saved with the following code. HPhotoLibrary.shared().performChanges({ PHAssetChangeRequest.creationRequestForAssetFromImage(atFileURL: jpgFileUrl) }, completionHandler: { (success: Bool, error: Error?) in print("success=\(success), error=\(String(describing: error))") }) Is this an iOS specification or a bug? Or is there a problem with the code? I would appreciate it if you could provide me with some information. Thank you in advance.

Hi Team, We are facing an issue with SMS messages on iOS regardless the version. Randomly, URL links in received messages are not clickable, regardless the carrier. Since it's hampering our business projects, we request you to look into the reported issue and suggest us with a possible solution or workaround. Scenario: Random regardless if first or third message, regardless link content, valid URLs are not detected as hyperlink while receiving receiving the same message again from same sender into same device, the URL underlines and it's clickable.

Since updating from 13.5.1 to 14.0 Public Beta 2 on my iPhone 11, I'm unable to turn on mobile data for specific apps. When wanting to change mobile data usage restrictions for apps, the system would not register the change of allowing mobile data. Description: Using Settings > Mobile Data, I find the specific app and select "WLAN & Mobile Data" from the 3 options. As soon as I leave this page to launch the app, I continue to receive a prompt asking me to allow mobile data in settings - eg the app is still disconnected. On the settings page, I find my selection of "WLAN & Mobile Data" reverted back to "WLAN" - usually as soon as I leave settings. Impact: This bug makes my iPhone a useless paperweight when it's not connected to WLAN. All apps that didn't have mobile data access prior to the update are affected. Common solutions I've tried (which didn't work): iPhone Restart / Force Restart Play around settings for mobile data - toggle roaming Reinsert sim / use a different sim. Delete and reinstall affected apps Disable Content & Privacy Restrictions in Settings > Screen Time Reset network settings Reference: Other users experienced a similar problem on earlier iOS versions which is commonly known as the toggle switch issues - check thread here - https://discussions.apple.com/thread/7219001. Is anyone else experiencing this bug in iOS 14? Any solutions or work arounds?
