使用错误号: |
答案:使用方法:当某个接口返回失败时,可以调用Hik_PlayM4_GetLastError来获得错误的详细信息。
错误 错误号定义如下: #define HIK_PLAYM4_NOERROR 0
#define HIK_PLAYM4_PARA_OVER 1
#define HIK_PLAYM4_ORDER_ERROR 2
#define HIK_PLAYM4_TIMER_ERROR 3
#define HIK_PLAYM4_DEC_VIDEO_ERROR 4
#define HIK_PLAYM4_DEC_AUDIO_ERROR 5
#define HIK_PLAYM4_ALLOC_MEMORY_ERROR 6
#define HIK_PLAYM4_OPEN_FILE_ERROR 7
#define HIK_PLAYM4_CREATE_OBJ_ERROR 8
#define HIK_PLAYM4_CREATE_DDRAW_ERROR 9
#define HIK_PLAYM4_CREATE_OFFSCREEN_ERROR 10
#define HIK_PLAYM4_BUF_OVER 11
#define HIK_PLAYM4_CREATE_SOUND_ERROR 12
#define HIK_PLAYM4_SET_VOLUME_ERROR 13
#define HIK_PLAYM4_SUPPORT_FILE_ONLY 14
#define HIK_PLAYM4_SUPPORT_STREAM_ONLY 15
#define HIK_PLAYM4_SYS_NOT_SUPPORT 16
#define HIK_PLAYM4_FILEHEADER_UNKNOWN 17
#define HIK_PLAYM4_VERSION_INCORRECT 18
