Detailed Description

Defines the creation time parameters for all IVIDTRANSCODE instance objects.

Remarks:

This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the size parameter.

The size field must be correctly set by the caller. See http://tiexpressdsp.com/index.php?title=Extending_data_structures_in_xDM for more details.

Field Documentation

XDAS_Int32 IVIDTRANSCODE_Params::size

Size of this structure in bytes. Because this structure can be extended, this field must be correctly set by the caller.

XDAS_Int32 IVIDTRANSCODE_Params::numOutputStreams

Number of output transcoded streams This allows the possibility of generating more than one transcoded bit-streams from a single incoming bit-stream.

XDAS_Int32 IVIDTRANSCODE_Params::formatInput

Video Format types.

Remarks:

This enumeration data type should not be used for storage, but rather only for its constant values.

This enumeration defines a base set of values. Algorithms which require proprietary enumeration values may define them - much like extended fields in base structures. These extended enums should be between XDM_CUSTOMENUMBASE and 0x7FFF.

See also:

XDM_CUSTOMENUMBASE

IVIDEO_Format

Remarks:

This is the video standard of incoming bit stream.

XDAS_Int32 IVIDTRANSCODE_Params::formatOutput[2]

Video Format types.

Remarks:

This enumeration data type should not be used for storage, but rather only for its constant values.

This enumeration defines a base set of values. Algorithms which require proprietary enumeration values may define them - much like extended fields in base structures. These extended enums should be between XDM_CUSTOMENUMBASE and 0x7FFF.

IVIDEO_Format

Remarks:

This array indicates the video standard for each of the transcoded bit streams.

XDAS_Int32 IVIDTRANSCODE_Params::maxHeightInput

Maximum video height in pixels.

XDAS_Int32 IVIDTRANSCODE_Params::maxWidthInput

Maximum video width in pixels.

XDAS_Int32 IVIDTRANSCODE_Params::maxFrameRateInput

Maximum frame rate in fps * 1000. For example, if max frame rate is 30 frames per second, set this field to 30000.

XDAS_Int32 IVIDTRANSCODE_Params::maxBitRateInput

Maximum bit rate, bits per second. For example, if bit rate is 10 Mbps, set this field to 10000000

XDAS_Int32 IVIDTRANSCODE_Params::maxHeightOutput[2]

Maximum output video height in pixels for each of the transcoded output.

XDAS_Int32 IVIDTRANSCODE_Params::maxWidthOutput[2]

Maximum output video width in pixels for each of the transcoded output.

XDAS_Int32 IVIDTRANSCODE_Params::maxFrameRateOutput[2]

Maximum frame rate in fps * 1000. for each out the output bitstreams For example, if max frame rate is 30 frames per second, set this field to 30000.

XDAS_Int32 IVIDTRANSCODE_Params::maxBitRateOutput[2]

Maximum bit rate, in bits per second for each of the transcoded bitstreams. For example, if bit rate is 10 Mbps, set this field to 10000000

XDAS_Int32 IVIDTRANSCODE_Params::dataEndianness

Endianness of output data.
