Member Function Documentation

bool PlayingState::GoToLive ( StreamBase &  stream )

overridevirtual

Perform the GoToLive action based on the stream state.

Parameters

stream

The stream instance.

Reimplemented from MediaController::StreamState.

Definition at line 38 of file StreamState.cpp.

                                              {
    // If the stream is already live then simply return.
    if (stream.GetMode() == Controller::kLive) return true;

    // The stream needs to be stopped since it will be transitioning from playback to live.
    return stream.Play();
}

void PlayingState::Pause ( StreamBase &  stream )

overridevirtual

Perform the Pause action based on the stream state.

Parameters

stream

The stream instance.

Reimplemented from MediaController::StreamState.

                                           {
    stream.Pause();
}

bool PlayingState::Play ( StreamBase &  stream, float  speed, unsigned int  unixTime  )

overridevirtual

Perform the Play action based on the stream state.

Parameters

stream	The stream instance.
speed	The playback speed.
unixTime	The start time for playback.

                                                                              {
    // Fast forward is not allowed if the stream is currently live so return
    // if it's attempted.
    if (stream.GetMode() == Controller::kLive) {
        if (speed < 0 || unixTime != 0) {
            return stream.Play(speed, unixTime == 0 ? stream.GetLastTimestamp() : unixTime);
        }
    }
    else {
        if (speed != stream.GetGstreamer()->GetSpeed() || unixTime != 0)
            return stream.Resume(speed, unixTime);
    }
