Fix: added new dng sdk 1.5.x

[Jamaika1]

I don't know will library have update?
I am adding patches to the latest dng sdk 1.5.x. Maybe it will be useful to someone.

Wonderful! Thank you very much! Why not create a PR to update the gpr library? I have already started updating expat, zlib, xmp, and cJSON. I have also included your changes to dng and gpr. But you obviously also changed VC5. For example VC5_ENCODER_PIXEL_FORMAT_RGGB_16 (https://github.com/Jamaika1/dng_sdk_1.5.1_-_gpr_sdk_1.0.0/blob/f9a54f80c5bd8eefa8f906824198d1b1628febeb/gpr_sdk/gpr.cpp#L157) is not included in the official code.

    typedef enum
    {
        VC5_ENCODER_PIXEL_FORMAT_RGGB_12 = 0,           // RGGB 14bit pixels packed into 16bits

        VC5_ENCODER_PIXEL_FORMAT_RGGB_12P = 1,           // RGGB 14bit pixels packed into 16bits

        VC5_ENCODER_PIXEL_FORMAT_RGGB_14 = 2,           // RGGB 14bit pixels packed into 16bits
        
        VC5_ENCODER_PIXEL_FORMAT_GBRG_12 = 3,           // GBRG 12bit pixels packed into 16bits
        
        VC5_ENCODER_PIXEL_FORMAT_GBRG_12P = 4,          // GBRG 12bit pixels packed into 12bits
        
        VC5_ENCODER_PIXEL_FORMAT_DEFAULT = VC5_ENCODER_PIXEL_FORMAT_RGGB_14,
        
    } VC5_ENCODER_PIXEL_FORMAT;

I guess you took the codec from the CineForm SDK and then rewrote the functions vc5_encoder_process (vc5_encoder.c) and vc5_decoder_process (vc5_decoder.c)? I am stuck at that point.

I shouldn't admit, but I'm not a programmer. As a programming hobbyist, I wanted to run the libraw library from DNG SDK and GPR SDK. The creator of libraw added camera Rapsberry Pi RAW+JPEG format (if USE_6BY9RPI defined) 8/12/14/16bit.

#ifdef USE_6BY9RPI
	void		rpi_load_raw8();
	void		rpi_load_raw12();
	void		rpi_load_raw14();
	void		rpi_load_raw16();
	void		parse_raspberrypi();
#endif

I also added GoPro GPR bayerphase 8/12/14/16bit. I realize that it isn't connected.

The new jpegXL codec 8/10/12/16bit is very much advertised.
What is the libraw problem. The converter has bad colormatrix for DNG SDK, but dng_validate seems to be valid.

This may be due to the imperfections of the gcc 10/11 software.

Not necessarily. The code is partly written very sloppily and contains numerous errors.

Example:

gpr/source/app/common/argument_parser/argument_parser.cpp

Line 88 in e956c59

printf("Executable: %s \n", get_application_path() );

The function get_application_path returns the variable application_path:

gpr/source/app/common/argument_parser/argument_parser.h

Line 39 in e956c59

const char* get_application_path() { return application_path; }

However, this variable is not set anywhere, which means that there are memory access errors. Actually all member variables of a class should be set in the constructor to avoid such errors. Alternatively you can use STL data types. Bugfix: OgreTransporter@10d7e9c

I used your code and did a complete upgrade of GPR. Thanks again for that! Probably there are still some minor corrections to be made.
