Detailed Description

Parameters for the DD+ decoder converter.

This data structure covers all parameters which can be set for the DD+ decoder converter. Setting these parameters is optional. If not the codec applies the mentioned defaults.

Note:
The various parameters are defined by the Dolby Digital Plus Subroutine API

Field Documentation

The audio decoder ID.

Note:
This field must be set to FAPEX_AUDEC_CODEC_TYPE_DDPDCV.

Enable AC-3 through SPDIF. If set this switch tells the DD+ decoder/converter to output the converted AC-3 via SPDIF. Otherwise it will output the PCM of the first two speakers in the associated audio output (AUOUT) via SPDIF as usual.

Note:
This switch takes only effect if SPDIF has been enabled for the audio output associated with the DD+ decoder/converter. A value of 0 or 1. (Codec's default: 0)

This parameter is not supported and must be set to NULL.

Dolby Digital Plus upsampling mode.

  • 0: Upsample based on bitstream metadata.
  • 1: Always perform upsampling.
  • 2: Never perform upsampling. (Codec's default: 0)

Dolby Digital Plus compression mode. A value between 0 and 3. (Codec's default: 2)

Dolby Digital Plus stereo output mode. A value between 0 and 2. (Codec's default: 0)

Dolby Digital Plus dual mono reproduction mode. A value between 0 and 3. (Codec's default: 0)

Dolby Digital Plus output channel configuration. A value between 1 to 7 or 9 to 15. (Codec's default: -1)

Note:
Bit 3 determines the LFE presence and bit 0-2 corresponds to the channel configuration code as described by the Dolby Digital Plus Subroutine API document.

The output channel configuration is usually automatically derived from the AUOUT driver's speaker configuration. Sometimes it could be desirable to overwrite this approach. For this purpose this parameter can be used. If the codec's current channel configuration should not be overwritten it must be set to -1.

Dolby Digital Plus maximum repeat count before muting. A value between -1 and 0. (Codec's default: -1)

Dummy to fill the gap.

Dolby Digital Plus dynamic range scale factor high level signals. A value between 0.0 and 1.0. (Codec's default: 1.0)

Dolby Digital Plus dynamic range scale factor low level signals. A value between 0.0 and 1.0. (Codec's default: 1.0)

Dolby Digital Plus PCM scale factor. A value between 0.0 and 1.0. (Codec's default: 1.0)
