Public Methods

Return	Name	Description
	`Device`	Construct a device with Unknown type and empty fields.
	`Device`	Construct a device with explicit fields.
`void`	`print` const	Print device details (type, id, name, capabilities) to the given stream.
`bool`	`operator==` const inline	Equality based on type, id, and name.
`VideoCapability`	`bestVideoCapability` const inline	Find the video capability closest to the requested parameters.
`AudioCapability`	`bestAudioCapability` const inline	Find the audio capability closest to the requested parameters.

Device()

Defined in src/av/include/icy/av/devicemanager.h:84

Construct a device with Unknown type and empty fields.

Device

Device(Type type, const std::string & id, const std::string & name, bool isDefault = false)

Defined in src/av/include/icy/av/devicemanager.h:91

Construct a device with explicit fields.

Parameters

Parameter	Type	Description
`type`	`Type`	The device type (VideoInput, AudioInput, etc.).
`id`	`const std::string &`	The platform-specific device identifier.
`name`	`const std::string &`	The human-readable device name.
`isDefault`	`bool`	True if this is the system default device of its type.

print

const

void print(std::ostream & os) const

Defined in src/av/include/icy/av/devicemanager.h:95

Print device details (type, id, name, capabilities) to the given stream.

Parameters

Parameter	Type	Description
`os`	`std::ostream &`	The output stream to write to.

operator==

const inline

inline bool operator==(const Device & that) const

Defined in src/av/include/icy/av/devicemanager.h:98

Equality based on type, id, and name.

bestVideoCapability

const inline

inline VideoCapability bestVideoCapability(int width, int height, double fps) const

Defined in src/av/include/icy/av/devicemanager.h:112

Find the video capability closest to the requested parameters.

Scoring: resolution match weighted 70%, fps match weighted 30%. Both dimensions are normalised to [0,1] so the weights are meaningful. Prefers capabilities that are >= the requested resolution (upscaling is worse than slight downscaling).

Returns a default capability with the requested values if none are available (allows callers to skip the empty check).

bestAudioCapability

const inline

inline AudioCapability bestAudioCapability(int sampleRate, int channels) const

Defined in src/av/include/icy/av/devicemanager.h:151

Find the audio capability closest to the requested parameters.

Scoring: sample rate match weighted 70%, channel count weighted 30%. Both dimensions are normalised to [0,1].

Returns a default capability with the requested values if none are available.
