MFORMATSLib Namespace > IMFFrame Interface : MFAudioGetBytes Method |
Here is an example of how to get a frame and get audio data's size and pointer:
m_objMFReader = new MFReaderClass(); m_objMFReader.ReaderOpen(sourceFileName, ""); m_avProps = new M_AV_PROPS(); // set video format for conversion m_avProps.vidProps.eVideoFormat = eMVideoFormat.eMVF_HD1080_5994i; MFFrame pFrame = null; // Get next frame or frame by position if (m_objMFReader != null) m_objMFReader.SourceFrameConvertedGetByTime(ref m_avProps, -1, -1, out pFrame, ""); int audioSize; long audioPointer; pFrame.MFAudioGetBytes(out videoSize, out videoPointer);
