[in] | handle | Handle to an algorithm instance. |
[in,out] | inBufs | Input buffer descriptors. |
[in,out] | outBufs | Output buffer descriptors. The algorithm may modify the output buffer pointers. |
[in] | inArgs | Input arguments. This is a required parameter. |
[out] | outArgs | Ouput results. This is a required parameter. |
inArgs
must not be NULL, and must point to a valid IVIDTRANSCODE_InArgs structure.outArgs
must not be NULL, and must point to a valid IVIDTRANSCODE_OutArgs structure.inBufs
must not be NULL, and must point to a valid XDM1_BufDesc structure.inBufs->descs
[0].buf must not be NULL, and must point to a valid buffer of data that is at least inBufs->descs
[0].bufSize bytes in length.outBufs
must not be NULL, and must point to a valid XDM_BufDesc structure.outBufs->buf
[0] must not be NULL, and must point to a valid buffer of data that is at least outBufs->bufSizes
[0] bytes in length.inBuf
and outBuf
are physically contiguous and owned by the calling application.inArgs
.inBufs
, with the exception of inBufs.bufDesc
[].accessMask. That is, the data and buffers pointed to by these parameters must be treated as read-only.inBufs->descs
[].accessMask and appropriately indicate the mode in which each of the buffers in inBufs
were read. For example, if the algorithm only read from inBufs.descs
[0].buf using the algorithm processor, it could utilize XDM_SETACCESSMODE_READ to update the appropriate accessMask
fields. The application may utilize these returned values to appropriately manage cache.inBufs
are owned by the calling application.IVIDTRANSCODE_EOK | Success. |
IVIDTRANSCODE_EFAIL | General failure. See IVIDTRANSCODE_Status::extendedError for more detailed further error conditions. |
