Field Documentation

OMX_BOOL OMX_AUDIO_CONFIG_CHANNELVOLUMETYPE::bIsMIDI
           TRUE if nChannel refers to a MIDI channel,

FALSE otherwise

Definition at line 1066 of file OMX_Audio.h.

OMX_BOOL OMX_AUDIO_CONFIG_CHANNELVOLUMETYPE::bLinear
           Is the volume to be set in linear (0.100) or 

logarithmic scale (mB)

Definition at line 1048 of file OMX_Audio.h.

OMX_U32 OMX_AUDIO_CONFIG_CHANNELVOLUMETYPE::nChannel
           channel to select from 0 to N-1, 

using OMX_ALL to apply volume settings to all channels

Definition at line 1045 of file OMX_Audio.h.

OMX_U32 OMX_AUDIO_CONFIG_CHANNELVOLUMETYPE::nPortIndex
         Port index indicating which port to 

set. Select the input port to set just that port's volume. Select the output port to adjust the master volume.

OMX_U32 OMX_AUDIO_CONFIG_CHANNELVOLUMETYPE::nSize

size of the structure in bytes

Definition at line 1038 of file OMX_Audio.h.

OMX_VERSIONTYPE OMX_AUDIO_CONFIG_CHANNELVOLUMETYPE::nVersion

OMX specification version information

Definition at line 1039 of file OMX_Audio.h.

OMX_BS32 OMX_AUDIO_CONFIG_CHANNELVOLUMETYPE::sVolume
           Volume linear setting in the 0..100 range, OR

Volume logarithmic setting for this port. The values for volume are in mB (millibels = 1/100 dB) relative to a gain of 1 (e.g. the output is the same as the input level). Values are in mB from nMax (maximum volume) to nMin mB (typically negative). Since the volume is "voltage" and not a "power", it takes a setting of -600 mB to decrease the volume by 1/2. If a component cannot accurately set the volume to the requested value, it must set the volume to the closest value BELOW the requested value. When getting the volume setting, the current actual volume must be returned.
