Macro Definition Documentation

◆ HIP_API_CALL

#define HIP_API_CALL (   call)
Value:
do { \
hipError_t hip_status = call; \
if (hip_status != hipSuccess) { \
const char *sz_err_name = NULL; \
sz_err_name = hipGetErrorName(hip_status); \
std::ostringstream error_log; \
error_log << "hip API error " << sz_err_name ; \
ROCDEC_THROW(error_log.str(), hip_status); \
} \
} \
while (0)

◆ ROCDEC_API_CALL

#define ROCDEC_API_CALL (   rocDecAPI)
Value:
do { \
rocDecStatus error_code = rocDecAPI; \
if( error_code != ROCDEC_SUCCESS) { \
std::ostringstream error_log; \
error_log << #rocDecAPI << " returned " << rocDecGetErrorName(error_code) << " at " <<__FILE__ <<":" << __LINE__;\
ROCDEC_THROW(error_log.str(), error_code); \
} \
} while (0)
rocDecGetErrorName
const char *ROCDECAPI rocDecGetErrorName(rocDecStatus rocdec_status)

Enumeration Type Documentation

◆ OutputSurfaceMemoryType_enum

enum OutputSurfaceMemoryType_enum
Enumerator
OUT_SURFACE_MEM_DEV_INTERNAL 

Internal interopped decoded surface memory(original mapped decoded surface)

OUT_SURFACE_MEM_DEV_COPIED 

decoded output will be copied to a separate device memory (the user doesn't need to call release)

OUT_SURFACE_MEM_HOST_COPIED 

decoded output will be copied to a separate host memory (the user doesn't need to call release)

OUT_SURFACE_MEM_NOT_MAPPED 

< decoded output is not available (interop won't be used): useful for decode only performance app
