Constructor & Destructor Documentation

◆ MediaFoundationReader()

MediaFoundationReader ( const juce::File &  file,
foleys::StreamTypes  type 
)

Member Function Documentation

◆ getMediaFile()

juce::File getMediaFile ( ) const
overridevirtual

Implements AVReader.

◆ getTotalLength()

juce::int64 getTotalLength ( ) const
overridevirtual

Returns the length in samples.

Note before prepareToPlay this returns the number of samples in the audio stream. Since the Reader will resample to suit the output, this number can change.

Implements AVReader.

◆ getLengthInSeconds()

double getLengthInSeconds ( ) const
overridevirtual

Returns the length of the clip in seconds.

Implements AVReader.

Referenced by MediaFoundationReader::Pimpl::getTotalLength().

◆ setPosition()

void setPosition ( const int64_t  position)
overridevirtual

Seek the reader to a certain position.

This position is given in audio samples

Implements AVReader.

◆ getStillImage()

juce::Image getStillImage ( double  seconds,
Size  size 
)
overridevirtual

This method allows direct access to a specific time to render thumbnails.

Don't use this to stream the video. Ideally use a separate reader for the thumbnails.

Implements AVReader.

◆ readNewData()

void readNewData ( VideoFifo &  videoFifo,
AudioFifo &  audioFifo 
)
overridevirtual

Implements AVReader.

◆ hasVideo()

bool hasVideo ( ) const
overridevirtual

Implements AVReader.

References MediaFoundationReader::getNumVideoStreams().

◆ hasAudio()

bool hasAudio ( ) const
overridevirtual

Implements AVReader.

References MediaFoundationReader::getNumAudioStreams().

◆ hasSubtitle()

bool hasSubtitle ( ) const
overridevirtual

Implements AVReader.

◆ setOutputSampleRate()

void setOutputSampleRate ( double  sampleRate)
overridevirtual

Implements AVReader.

References AVReader::sampleRate.

◆ getNumVideoStreams()

int getNumVideoStreams ( ) const
overridevirtual

Implements AVReader.

Referenced by MediaFoundationReader::hasVideo().

◆ getVideoSettings()

VideoStreamSettings getVideoSettings ( int  streamIndex) const
overridevirtual

Implements AVReader.

◆ getNumAudioStreams()

int getNumAudioStreams ( ) const
overridevirtual

Implements AVReader.

Referenced by MediaFoundationReader::hasAudio().

◆ getAudioSettings()

AudioStreamSettings getAudioSettings ( int  streamIndex) const
overridevirtual

Implements AVReader.
