Detailed Description

Public media stream snapshot.

One media stream: registry Codec, duration, properties and tags.

Copies share the same Codec instance. The Codec outlives every Stream. Assignment is deleted because Codec is held by reference.

Audio()

const Property::Audio * StormByte::Multimedia::Stream::Audio ( ) const

inlinenoexcept

Audio properties when this stream is audio.

Returns

Pointer to properties, or nullptr.

Codec()

const class Codec & StormByte::Multimedia::Stream::Codec ( ) const

delete

Copy assignment (deleted: Codec is a reference).

Returns

*this.

operator=() [2/2]

Stream & StormByte::Multimedia::Stream::operator= ( Stream &&  )

delete
