Detailed Description

Simple implementation of a Multi-Threaded CMJ2Enc.

If bMT is TRUE:

• This class encodes 2 fields or 2 frames in a multi-threaded operation. The 1st one on a thread running on another CPU and the 2nd one on the CPU running the current thread.

If bMT is FALSE:

• It encodes a single frame or field on the current thread.

Remarks:

bMT is passed to constructor CMJ2EncMT().

The calling sequence in a multi-threaded operation is :

• prepare()
• encode()
• sync()

Examples:

jp2_encodeMT.cpp.

Member Function Documentation

virtual int CMJ2EncMT::prepare (  JPEG2000INFOHEADER2 *  jp2, int  argc, char **  argv, BYTE *  in, int  in_size, int  in_ofs, int  in_row, int  in_width, int  in_height, DWORD  in_fcc, int  in_bits, BYTE *  out, int  out_size, int  out_quality, int  out_desired_size )  [inline, virtual]

Prepare 1st field or frame encoding in a multi-threaded operation (bMT was TRUE when passed to constructor CMJ2EncMT()). Parameters: see  IMJ2Enc::encode(). Returns: 0 on success. -1 if bMT was FALSE when passed to constructor CMJ2EncMT(). Examples: jp2_encodeMT.cpp.

Here is the call graph for this function:

virtual int CMJ2EncMT::encode (  JPEG2000INFOHEADER2 *  jp2, int  argc, char **  argv, BYTE *  in, int  in_size, int  in_ofs, int  in_row, int  in_width, int  in_height, DWORD  in_fcc, int  in_bits, BYTE *  out, int  out_size, int  out_quality, int  out_desired_size )  [inline, virtual]

Encode 1 frame/field or 2 frames/fields. Parameters: see  IMJ2Enc::encode(). If bMT was FALSE when passed to constructor CMJ2EncMT(): Encode 1 frame or field. If bMT was TRUE when passed to constructor CMJ2EncMT(): Encode 2 frames or 2 fields in a multi-threaded operation. Returns: If bMT was FALSE: The size in bytes of the field or frame encoded. If bMT was TRUE: The size in bytes of the 2nd field or frame encoded. Reimplemented from IMJ2Enc. Examples: jp2_encodeMT.cpp.

Here is the call graph for this function:

virtual int CMJ2EncMT::sync (   )  [inline, virtual]

Wait for completion of 1st field or frame encoding in a multi-threaded operation (bMT was TRUE when passed to constructor CMJ2EncMT()). Returns: The size in bytes of the 1st field or frame encoded. 0 if bMT was FALSE when passed to constructor CMJ2EncMT(). Examples: jp2_encodeMT.cpp.
