codec engine 移植 opencv emcv 记录 cv相关文件
1.在int 中加括号
CV_INLINE int cvRound( double value )
{
return (int)(floor(value+0.5));
}
CV_INLINE int cvFloor( double value )
{
return (int)(floor(value));
}
CV_INLINE int cvCeil( double value )
{
return (int)(ceil(value));
}
可能是编译器的问题，（int）
2.把32去掉
CV_INLINE void* cvAlignPtr( const void* ptr, int align )//
{
assert( (align & (align-1)) == 0 );
return (void*)( ((size_t)ptr + align - 1) & ~(size_t)(align-1) );
}
3. size 赋值
CV_INLINE CvSize cvGetMatSize( const CvMat* mat )
{
// CvSize size = { mat->width, mat->height };
CvSize size;
size.width = mat->cols;
size.height = mat->rows;
return size;
}
4.去掉重复声明
/opt/DM3730/dvsdk/codec-engine_2_26_02_11/examples/ti/sdo/ce/examples/codecs/videnc_copy/EMCV/cxcore/cxmisc.h:724: error: redefinition of typedef 'CvFunc2DnC_1A1P'
#if 0
typedef CvStatus (CV_STDCALL *CvFunc2DnC_1A1P)( void* arr, int step, CvSize size,
int cn, int coi, void* param );
#endif
typedef CvStatus (CV_STDCALL *CvFunc2DnC_1A1P)( void* arr, int step, CvSize size,
int cn, int coi, void* param );
#if 0
typedef CvStatus (CV_STDCALL *CvFunc2DnC_2A1P)( void* arr0, int step0,
void* arr1, int step1,
CvSize size, int cn,
int coi, void* param );
#endif
typedef CvStatus (CV_STDCALL *CvFunc2DnC_2A1P)( void* arr0, int step0,
void* arr1, int step1,
CvSize size, int cn,
int coi, void* param );
5.去掉一些 dsp库的汇编函数

void icvErode_8UC1
(
const unsigned char *restrict in_data,
unsigned char *restrict out_data,
const char *restrict mask,
int cols,
int step
)
去掉restrict，这不是c标准库的东西吗，怎么也不支持？ 我用的是arm-arago-linux-gnueabi- 编译
p0 = (_mem4_const(&in_data[i ]));
p3 = (_mem4_const(&in_data[i + step ]));
p6 = (_mem4_const(&in_data[i + step*2]));
p1 = p0>>8; p2 = p0>>16;
p4 = p3>>8; p5 = p3>>16;
p7 = p6>>8; p8 = p6>>16;
result = p4 & 0xFFFF;
result = m0 ? _minu4(result, p0) : result;
result = m1 ? _minu4(result, p1) : result;
result = m2 ? _minu4(result, p2) : result;
result = m3 ? _minu4(result, p3) : result;
result = m5 ? _minu4(result, p5) : result;
result = m6 ? _minu4(result, p6) : result;
result = m7 ? _minu4(result, p7) : result;
result = m8 ? _minu4(result, p8) : result;
修改以上，用c的东西，不知道逻辑是不是对的，有待验证
for (i = 0; i < cols-2; i += 2)
{
p0 = ((in_data[i ]));
p3 = ((in_data[i + step ]));
p6 = ((in_data[i + step*2]));
p1 = p0>>8; p2 = p0>>16;
p4 = p3>>8; p5 = p3>>16;
p7 = p6>>8; p8 = p6>>16;
result = p4 & 0xFFFF;
result = m0 ? MIN(result, p0) : result;
result = m1 ? MIN(result, p1) : result;
result = m2 ? MIN(result, p2) : result;
result = m3 ? MIN(result, p3) : result;
result = m5 ? MIN(result, p5) : result;
result = m6 ? MIN(result, p6) : result;
result = m7 ? MIN(result, p7) : result;
result = m8 ? MIN(result, p8) : result;
还有：
for (i = 0; i < cols-2; i += 2)
{
p0 = ((in_data[i ]));
p3 = ((in_data[i + step ]));
p6 = ((in_data[i + step*2]));
p1 = p0>>8; p2 = p0>>16;
p4 = p3>>8; p5 = p3>>16;
p7 = p6>>8; p8 = p6>>16;
result = p4 & 0xFFFF;
result = m0 ? MAX(result, p0) : result;
result = m1 ? MAX(result, p1) : result;
result = m2 ? MAX(result, p2) : result;
result = m3 ? MAX(result, p3) : result;
result = m5 ? MAX(result, p5) : result;
result = m6 ? MAX(result, p6) : result;
result = m7 ? MAX(result, p7) : result;
result = m8 ? MAX(result, p8) : result;
out_data[i] = (result & 0xFF);
out_data[i+1] = (result>>8 & 0xFF);
经过以上，cv相关文件，可以在codec engine中编译通过
