Member Function Documentation

create()

static std::unique_ptr<FFmpegStreamInputController> alexaClientSDK::mediaPlayer::android::FFmpegStreamInputController::create ( std::shared_ptr< std::istream >  stream, bool  repeat  )

static

Creates an input stream object.

Parameters

input	A pointer to the input stream. It shall point to a valid object.
repeat	Whether to play the input stream in a loop.

Returns

A pointer to the FFmpegStreamInputController if succeed; nullptr otherwise.

getCurrentFormatContext()

std::tuple<Result, std::shared_ptr<AVFormatContext>, std::chrono::milliseconds> alexaClientSDK::mediaPlayer::android::FFmpegStreamInputController::getCurrentFormatContext ( )

overridevirtual

This method will initialize the ffmpeg format context that represents the current input stream.

Returns

A tuple with the return result, a pointer to AVFormatContext and the initial playback position.

Implements alexaClientSDK::mediaPlayer::android::FFmpegInputControllerInterface.

hasNext()

bool alexaClientSDK::mediaPlayer::android::FFmpegStreamInputController::hasNext ( ) const

overridevirtual

Checks if there is a next track to be played.

Returns

true if there is a next track; false, otherwise.

Implements alexaClientSDK::mediaPlayer::android::FFmpegInputControllerInterface.

next()

bool alexaClientSDK::mediaPlayer::android::FFmpegStreamInputController::next ( )

overridevirtual

Change input to the next track to be played.

Returns

true if it succeeds to change; false, otherwise.

Implements alexaClientSDK::mediaPlayer::android::FFmpegInputControllerInterface.
