IAVObject interface
Init
HRESULT Init()
Производит инициализацию данных объекта, для объектов - сплитеров или ридеров производит открытие файлов и начальный парсинг.
Close
HRESULT Close()
Освобождает ресурсы используемые объектом, закрывает файлы, освобождает блоки памяти.
BeginFlush
HRESULT BeginFlush()
EndFlush
HRESULT EndFlush()
Convert
HRESULT Convert( [in] BYTE* pbSrc, [in] int cbSrc, [in] BYTE* pbDst, [in] int cbDst, [out] int* pcbActual, [in] int nReserved, [in] BYTE* pbReserved );
Method for synchronous conversions. If this method is implemented then methods for asynchronous conversions (CanPutFrame(), PutFrame(), CanGetFrame(), GetFrame()) can be not implemented.
| Parameters: | |
| pbSrc | Source buffer for conversion. |
| cbSrc | Size of data in source buffer in bytes. |
| pbDst | Destination buffer for result of conversion. |
| cbDst | Size of destination buffer in bytes |
| pcbActual | Size of returned data in destination buffer in bytes |
| nReserved | Library specific variable (see library description) |
| pbReserved | Library specific variable (see library description) |
CanPutFrame
HRESULT CanPutFrame( [in] int nStream, [in] DWORD nWait );
Метод проверяет возможность отправки данных объекту
| Parameters: | |
| nStream | Number of stream |
| nWait | Время ожидания ответа в мкс. |
PutFrame
HRESULT PutFrame( [in] int nStream, [in] BYTE* pbBuffer, [in] DWORD cbActual, [in] DWORD dwFlags, [in] REFERENCE_TIME tS, [in] REFERENCE_TIME tE, [in] BYTE* pbReserved );
Метод для отправки данных объекту
| Parameters: | |
| nStream | Number of stream |
| pbBuffer | Buffer with data. |
| cbActual | Size of data in buffer in bytes. |
| dwFlags | Library specific bitmap (see library description) |
| tS | Start time |
| tE | End time |
| pbReserved | Library specific variable (see library description) |
CanGetFrame
HRESULT CanGetFrame( [in] int nStream, [in] DWORD nWait );
Метод проверяет возможность получения данных от объекта
| Parameters: | |
| nStream | Number of stream |
| nWait | Время ожидания ответа в мкс. |
GetFrame
HRESULT GettFrame( [in] int nStream, [in] BYTE* pbBuffer, [in] DWORD cbBuffer, [out] DWORD* pcbActual, [out] DWORD* pdwFlags, [out] REFERENCE_TIME* ptS, [out] REFERENCE_TIME* ptE, [out] BYTE** pbReserved );
Метод для отправки данных объекту
| Parameters: | |
| nStream | Number of stream |
| pbBuffer | Buffer for data. |
| cbBuffer | Size of data in buffer in bytes. |
| cbActual | Size of received data buffer in bytes. |
| pdwFlags | Library specific bitmap (see library description) |
| ptS | Start time |
| tE | End time |
| pbReserved | Library specific variable (see library description) |
