Apple AVAudioSessionCategoryMultiRoute AVAudioSessionCategoryPlayback input output setCategory route recording documentation
💡 Result:
The AVAudioSession category you choose dictates whether your app can perform audio input (recording) and output (playback) simultaneously. AVAudioSessionCategoryPlayback is strictly for audio output and does not support audio input [1]. If your application requires both recording and playback, you must use a category that supports both, such as AVAudioSessionCategoryPlayAndRecord or AVAudioSessionCategoryMultiRoute [1][2]. Key differences for your use case: 1. AVAudioSessionCategoryPlayback: Designed exclusively for apps where media playback is the primary function [3]. It does not allow audio recording [1]. 2. AVAudioSessionCategoryPlayAndRecord: The standard choice for applications requiring both input and output, such as VoIP or voice chat apps [4]. 3. AVAudioSessionCategoryMultiRoute: An advanced category that allows you to route audio to multiple output devices simultaneously (e.g., USB and headphones) [5][2]. Like PlayAndRecord, it supports both input and output [2][6]. It is unique in that it allows the system to send different audio streams to different output ports, whereas other categories typically follow a "last-in wins" rule for output devices [5]. If you are currently using Playback and attempting to record, the system will prevent input from being captured [1]. To enable recording alongside playback, you should switch your category to PlayAndRecord or, if you specifically need the advanced multi-output routing features, to MultiRoute [2][4]. Note that switching to these categories may change how your app interacts with other audio on the system (e.g., whether it mixes with others or interrupts them) [1][5][7], so you may need to configure the appropriate AVAudioSession.CategoryOptions, such as.mixWithOthers, to achieve your desired behavior [5][7].

Preserve AVAudioSessionCategoryMultiRoute.
When session.category is AVAudioSessionCategoryMultiRoute, CFLTConfigureAudioSession selects AVAudioSessionCategoryPlayback at both call sites. AVAudioSessionCategoryPlayback does not support audio input, so this can disable the active recording route. Preserve AVAudioSessionCategoryMultiRoute when updating the mix option.

Apple AVAudioSession setCategory withOptions error invalid category options behavior categoryOptions documentation
💡 Result:
When using AVAudioSession's setCategory(:options:error:) (or equivalent methods like setCategory(:mode:options:)), Apple's documentation explicitly states that specifying an unsupported or incompatible option for a given category results in an error [1][2]. The behavior of these methods when provided with invalid category options includes: 1. Method Failure: The method call will fail, returning a boolean false (in Objective-C) or throwing an error (in Swift) [1][2]. 2. Error Code: The error returned is typically an AVAudioSessionErrorCodeBadParam (often represented by the OS error code -50) [3][4]. 3. No Change: Because the operation fails, the audio session's previous state for category, mode, and options remains unchanged. Key constraints and compatibility rules include: - Category-Specific Requirements: Certain options are restricted to specific categories. For example, the.defaultToSpeaker option is specifically designed for the.playAndRecord category [3]. Attempting to apply it to a category like.record or.playback without proper context can trigger an error [3]. - Mode Compatibility: While setting options, it is also important that the chosen mode is compatible with the selected category [4][5]. The system evaluates the combination of category, mode, and options as a unified configuration [1][6]. - Best Practices: Apple recommends using methods that allow you to set the category, mode, and options simultaneously (such as setCategory(_:mode:options:)) to ensure the entire configuration is applied atomically, rather than setting these properties independently [1][2]. If your application triggers an error during this process, verify that all selected options are explicitly compatible with your chosen AVAudioSession.Category, and ensure your mode choice is valid for that category according to Apple's documentation [1][7][5].

site:developer.apple.com AVAudioSessionCategoryOptions AVAudioSessionCategoryOptionDefaultToSpeaker valid categories AllowBluetooth MultiRoute Playback
💡 Result:
The AVAudioSessionCategoryOptionDefaultToSpeaker option is specifically designed to be used only with the AVAudioSessionCategoryPlayAndRecord category [1][2]. It modifies the category's routing behavior to ensure audio is routed to the built-in speaker instead of the receiver, provided no other accessories (such as headphones or Bluetooth devices) are in use [1][2]. Regarding the options you mentioned: AVAudioSessionCategoryOptionAllowBluetooth: This option is a modifier for categories that support input (like PlayAndRecord) to allow Bluetooth hands-free devices as input routes [3]. It is distinct from DefaultToSpeaker, although both can be set when using the PlayAndRecord category to customize its behavior. AVAudioSessionCategoryMultiRoute: This is an entirely separate audio session category, not a category option [4]. Because DefaultToSpeaker is specifically a modifier for the PlayAndRecord category, it is not valid for use with the MultiRoute category [1]. AVAudioSessionCategoryPlayback: This is also a distinct category, not an option [4]. DefaultToSpeaker is not applicable here because the Playback category is designed solely for output and does not have a "receiver" vs. "speaker" routing logic in the same way the PlayAndRecord category does [1][4]. In summary, DefaultToSpeaker is a specialized modifier reserved for the PlayAndRecord category [1][2]. Attempts to use it with other categories or as a standalone configuration will not function as expected [1].

Apple AVAudioSession category options table MultiRoute AllowBluetooth AllowAirPlay AllowBluetoothA2DP Playback valid categories
💡 Result:
In Apple's AVAudioSession framework, category options are used to modify the default behavior of specific audio categories [1][2]. These options are not universally applicable; each is valid only for specific categories [3][4]. Below is a breakdown of the requested options and their general compatibility based on Apple's documentation [4]: AVAudioSessionCategoryOptionAllowAirPlay This option determines whether you can stream audio from the session to AirPlay devices [4]. Note that AirPlay routing behavior is also heavily influenced by the chosen category itself: - Supported: The playback-only categories (AVAudioSessionCategoryAmbient, AVAudioSessionCategorySoloAmbient, and AVAudioSessionCategoryPlayback) generally support AirPlay routing [5][6]. - Restricted: AVAudioSessionCategoryPlayAndRecord supports only mirrored AirPlay, while AVAudioSessionCategoryMultiRoute and AVAudioSessionCategoryRecord do not support routing to AirPlay [5][6]. AVAudioSessionCategoryOptionAllowBluetooth This option determines whether Bluetooth hands-free (HFP) devices appear as available input routes [4]. It is commonly used with categories that support input, such as AVAudioSessionCategoryPlayAndRecord [5][7]. AVAudioSessionCategoryOptionAllowBluetoothA2DP This option enables streaming audio to Bluetooth devices that support the Advanced Audio Distribution Profile (A2DP) [4]. AVAudioSessionCategoryPlayback This is a standard category intended for apps where audio playback is central, such as music or media players [6]. By default, it interrupts other system audio, but this can be modified using options like AVAudioSessionCategoryOptionMixWithOthers [1][7]. Regarding AVAudioSessionCategoryMultiRoute: The MultiRoute category is distinct because it allows an app to route different audio streams to different output devices simultaneously [1][6]. While powerful, it has specific constraints and behaviors regarding input and output ports that differ from standard categories [1]. It does not support AirPlay [5][6]. Important Note: Always check the latest Apple Developer Documentation for AVAudioSession.CategoryOptions, as specific compatibility can evolve with iOS and macOS versions [4]. When setting these, use the setCategory(_:mode:options:) method to apply the desired category, mode, and options simultaneously [8].

"static void CFLTConfigureAudioSession" "targetOptions"
💡 Result:
The term CFLTConfigureAudioSession does not appear in standard documentation for major cross-platform audio frameworks or the LiveKit client SDKs [1][2][3]. It is likely a project-specific function, a typo, or a internal helper method within a custom implementation. In the context of cross-platform audio management (such as the popular audio_session Flutter package), developers typically use methods like session.configure(AudioSessionConfiguration(...)) to set up platform-specific audio behaviors [4][5][6]. If you are encountering this in a specific codebase, you may want to: 1. Search the project directory for the definition of CFLTConfigureAudioSession to identify where it is declared. 2. Check if it is a wrapper for platform-native calls like AVAudioSession (iOS) or AudioManager (Android) [7][6]. 3. If you are trying to configure an audio session in a Flutter or React Native project, rely on the established configuration patterns provided by the libraries you are using [4][3][5][7]. For example, in many Flutter applications using the audio_session plugin, configuration is handled via: final session = await AudioSession.instance; await session.configure(AudioSessionConfiguration.music); If you provide more context—such as the specific framework, library, or language—I can provide a more tailored explanation.

site:developer.apple.com/documentation/avfaudio/avaudiosession/categoryoptions "valid" category option setCategory
💡 Result:
In the context of Apple's AVAudioSession framework, there is no single "setCategory" function that takes a "valid category option" as an argument in a generic way; instead, developers configure audio sessions using specific category constants and associated category options [1]. Audio session behavior is defined by choosing an AVAudioSession.Category and then applying specific AVAudioSession.CategoryOptions [1]. Crucially, each category option is only valid for certain categories [1]. For example: - defaultToSpeaker: This option is only valid when using the playAndRecord category [2]. - allowBluetoothHFP: This option is only valid with the record and playAndRecord categories [3]. - mixWithOthers: This option can be set explicitly only if the category is playAndRecord, playback, or multiRoute [4]. Other categories, such as ambient, set this option automatically [4]. - farFieldInput: This option is only valid with categories that support input, such as playAndRecord, record, and AVAudioSessionMultiRoute with dualRoute [1][4]. Developers must ensure that the options they attempt to apply are compatible with the currently selected category to avoid unexpected behavior or configuration errors [1].

AVAudioSessionCategoryMultiRoute category options allowBluetoothA2DP mixWithOthers duckOthers defaultToSpeaker valid
💡 Result:
When configuring an AVAudioSession with the multiRoute category, the validity of specific category options varies. Below is a breakdown of the requested options for AVAudioSessionCategoryMultiRoute: 1. mixWithOthers: Valid. You can set this option with multiRoute [1][2]. It indicates whether audio from your session mixes with audio from other active sessions [1]. 2. duckOthers: Valid. You can set this option with multiRoute [2]. It reduces the volume of other audio sessions while your audio plays [1][3]. 3. allowBluetoothA2DP: Invalid (not supported). While this option exists for other categories (such as playAndRecord), it is explicitly false and cannot be set to true when using the multiRoute category [4][5][6]. 4. defaultToSpeaker: Invalid (not supported). This option is only valid for the playAndRecord category [3][2]. It cannot be used with multiRoute [2]. In summary, for multiRoute, you may use mixWithOthers and duckOthers, but allowBluetoothA2DP and defaultToSpeaker are not supported [1][3][2][4].

Apple AVPlayerItemVideoOutput initWithPixelBufferAttributes initWithOutputSettings AVVideoColorPropertiesKey documentation
💡 Result:
AVPlayerItemVideoOutput provides two primary initialization methods for configuring how video frames are output from an AVPlayerItem: 1. initWithPixelBufferAttributes: This method initializes the output object with a dictionary of Core Video pixel buffer attributes, such as the pixel format type (e.g., kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange) [1][2]. It is primarily used for requesting uncompressed video output with specific pixel buffer characteristics [1][3]. 2. initWithOutputSettings: This method initializes the output object with a dictionary of output settings [1][4]. These settings allow for more granular control over the output, including support for wide color and specific color space tagging [3][5]. AVVideoColorPropertiesKey is a key that can be used within the output settings dictionary provided to initWithOutputSettings: [6]. It is used to specify or override the color properties of the video output [6]. When this key is included, the associated dictionary must contain values for the following three properties: - AVVideoColorPrimariesKey [5] - AVVideoTransferFunctionKey [5] - AVVideoYCbCrMatrixKey [5] If AVVideoColorPropertiesKey is set, AVFoundation will perform color conversion if necessary to match the specified properties, and the resulting pixel buffers will be tagged according to these settings [6]. If it is not set, the output typically inherits the color properties of the source buffers [6]. Note that these settings must yield uncompressed video output; specifying settings that result in compressed video will cause the method to throw an exception [3].

Pass the color dictionary through initWithOutputSettings:. AVVideoColorPropertiesKey is an output-settings key, but both AVPlayerItemVideoOutput instances pass it through initWithPixelBufferAttributes:. The color conversion request may therefore be ignored, leaving wide-color or HDR frames with incorrect colors. Update both call sites at lines 214 and 331.

Apple Foundation NSURL URLWithString relative URL documentation absoluteURL scheme
💡 Result:
In Apple's Foundation framework, an NSURL object is composed of two primary parts: an optional base URL and a relative string that is resolved against that base [1][2]. An NSURL is considered absolute if its string part is fully resolved without requiring a base URL [1][2]. Conversely, if a base URL is provided, the object is considered relative [1]. Key concepts and behaviors: 1. URL Construction: The method URLWithString:relativeToURL: (or the Swift equivalent init(string:relativeTo:)) initializes an NSURL by resolving a relative string against a base URL [1][3]. 2. Resolution Behavior: How a string is resolved relative to a base URL depends on the string's content [4][5]. If the relative string begins with a slash (e.g., /foo), it is treated as an absolute path, effectively ignoring the path component of the base URL [4][5]. To append a path segment correctly, the base URL should end with a trailing slash (e.g., base/folder/), and the relative string should not start with a slash (e.g., file.html) [4][5]. 3. Parsing Updates: For applications linked on or after iOS 17 and aligned OS versions, NSURL parsing has been updated to follow RFC 3986, replacing the previous, obsolete RFC 1738/1808 parsing [3][6]. This aligns NSURL with the parsing behavior of NSURLComponents [3]. 4. AbsoluteURL Property: The absoluteURL property returns an absolute NSURL object that refers to the same resource as the receiver [1][7]. If the receiver is already absolute, it returns the receiver itself [8]. 5. Scheme: The scheme property (e.g., http, file) is a read-only attribute of the URL [1]. For developers, it is important to ensure the base URL properly represents the directory structure (usually by including a trailing slash) if the intent is to append to the existing path rather than replace it [4].

Reject relative video URIs.
NSURL URLWithString: accepts relative URLs. A URI such as video.mp4 passes the !url check, makes isFileURL false, and reaches a video data-source method. Return the existing Invalid video URI error when the URL is not absolute.

Summary
AVURLAssetCurefit compatibility
Root cause
video_player_cfcreates anAVMutableVideoCompositionfor the Flutter texture path. Its former rotation-specific translation workaround only adjusted zero-translation transforms and assumed rotation alone determined the render size. Compressed portrait MP4s retain a preferred transform with translation metadata, allowing composition frames to fall outside its render bounds. AVPlayer still decodes the file, but Flutter receives a black texture.Fix
Validation
