Member Function Documentation

ReadFrame()

HRESULT GrayLib::cFLVFileReader::ReadFrame ( const cFLVTag &  tag )

protected

Read a TAG_VIDEO or TAG_AUDIO frame. Each frame has its own complete header in bFormFlag.

Todo:

handle compression format change mid stream.

ReadMeta()

HRESULT GrayLib::cFLVFileReader::ReadMeta ( UINT32  uLenBlockMax, FLV_META_TYPE  eTypeEnd, UINT32  uQtyMax  )

protected

Read a SCRIPTDATAOBJECT array from TAG_META. defined in http://www.adobe.com/devnet/flv/pdf/video_file_format_spec_v9.pdf

Note

The public spec as of 4/2010 is wrong !
