Types

enum	AvailabilityStatus { Available, ServiceMissing, ResourceError, Busy }
enum	EncodingMode { ConstantQualityEncoding, ConstantBitRateEncoding, AverageBitRateEncoding, TwoPassEncoding }
enum	EncodingQuality { VeryLowQuality, LowQuality, NormalQuality, HighQuality, VeryHighQuality }
enum	SupportEstimate { NotSupported, MaybeSupported, ProbablySupported, PreferredService }

Enumerates Service status errors.

Constant	Value	Description
`QMultimedia::Available`	`0`	The service is operating correctly.
`QMultimedia::ServiceMissing`	`1`	There is no service available to provide the requested functionality.
`QMultimedia::ResourceError`	`3`	The service could not allocate resources required to function correctly.
`QMultimedia::Busy`	`2`	The service must wait for access to necessary resources.

Enumerates encoding modes.

Constant	Value	Description
`QMultimedia::ConstantQualityEncoding`	`0`	Encoding will aim to have a constant quality, adjusting bitrate to fit.
`QMultimedia::ConstantBitRateEncoding`	`1`	Encoding will use a constant bit rate, adjust quality to fit.
`QMultimedia::AverageBitRateEncoding`	`2`	Encoding will try to keep an average bitrate setting, but will use more or less as needed.
`QMultimedia::TwoPassEncoding`	`3`	The media will first be processed to determine the characteristics, and then processed a second time allocating more bits to the areas that need it.

Enumerates quality encoding levels.

Constant	Value
`QMultimedia::VeryLowQuality`	`0`
`QMultimedia::LowQuality`	`1`
`QMultimedia::NormalQuality`	`2`
`QMultimedia::HighQuality`	`3`
`QMultimedia::VeryHighQuality`	`4`

Enumerates the levels of support a media service provider may have for a feature.

Constant	Value	Description
`QMultimedia::NotSupported`	`0`	The feature is not supported.
`QMultimedia::MaybeSupported`	`1`	The feature may be supported.
`QMultimedia::ProbablySupported`	`2`	The feature is probably supported.
`QMultimedia::PreferredService`	`3`	The service is the preferred provider of a service.
