IVFReader is used to read IVF files and return frame payloads

func (*IVFReader) ParseNextFrame

func (i *IVFReader) ParseNextFrame() ([]byte, *IVFFrameHeader, error)

ParseNextFrame reads from stream and returns IVF frame payload, header, and an error if there is incomplete frame data. Returns all nil values when no more frames are available.

func (*IVFReader) ResetReader

func (i *IVFReader) ResetReader(reset func(bytesRead int64) io.Reader)

ResetReader resets the internal stream of IVFReader. This is useful for live streams, where the end of the file might be read without the data being finished.
