MID2226_API int S2226_TestDecodeDone(
HANDLE hdev
);
If message received, tests if decode was finished in the driver. This is NOT, however, when decode
stops on the codec chip. It is only when the driver is finished with the data. A future update will
correct this limitation.
Because the data is compressed and there are buffers on the board, TestDecodeDone may be
early by a substantial amount.
Parameters
hdev
handle to device (obtained from S2226_OpenBoard).
Returns
0 on success, negative value if error (see mid2226types.h for error codes list).
MID2226_API int S2226_SetPreviewType(
MID2226_PREVIEWTYPE type,
HANDLE hdev
);
Sets the preview type (on the host computer, NOT the 2226 physical outputs). Raw preview is
downscaled to 320x240 or 640x480 resolution to meet USB2.0 bandwith requirements (combined
with the MPEG stream).
Parameters
type
Preview type (raw or decoded MPEG stream)
hdev
handle to device (obtained from S2226_OpenBoard).
Returns
0 on success, negative value if error (see mid2226types.h for error codes list).
