SYNOPSIS
#include <dmedia/dm_audioutil.h>
#include <dmedia/dm_audio.h>
#include <dmedia/dm_params.h>
DMstatus dmDVAudioEncoderSetParams(DMDVaudioencoder handle,
DMparams *params)
PARAMETER
handle DMDVaudioencoder structure, created by
dmDVAudioEncoderCreate(3dm).
params list of parameters to configure the audio encoder. Null (0)
value ok.
RETURNED VALUE
Returns DM_SUCCESS or DM_FAILURE.
DESCRIPTIONdmDVAudioEncoderSetParams(3dm) sets state of the DV audio encoder to the
values specified in params. Unrecognized parameters are ignored.
The parameters that params can have specified are defined in
dmedia/dm_audioutil.h:
DM_DVAUDIO_FORMAT - required, either DM_DVAUDIO_NTSC or DM_DVAUDIO_PAL
DM_DVAUDIO_TYPE - not required, either DM_DVAUDIO_DV or
DM_DVAUDIO_DVCPRO, defaults to DM_DVAUDIO_DV
DM_AUDIO_CHANNELS - required, number of channels of audio (1 or 2) If
f3DM_DVAUDIO_TYPE is DM_DVAUDIO_DVCPRO, this must be 2.
DM_AUDIO_WIDTH - should always be 16
DM_MEDIUM - should always be DM_AUDIO
DM_AUDIO_RATE - required, the sample rate in floating point (ex: 48000.0)
If the DM_DVAUDIO_TYPE is DM_DVAUDIO_DVCPRO, only 48 kHz is supported.
If the DM_DVAUDIO_TYPE is DM_DVAUDIO_DV, both 32 kHz and 48 kHz are
supported.
DM_DVAUDIO_LOCK_MODE - not required, non-zero if audio is locked
according to the DV audio specification. Zero if it is not locked.
Defaults to locked audio.
