Relevant Struct Members
cannam@86:
cannam@86:
version
cannam@86:
Vorbis encoder version used to create this bitstream.
cannam@86:
channels
cannam@86:
Int signifying number of channels in bitstream.
cannam@86:
rate
cannam@86:
Sampling rate of the bitstream.
cannam@86:
bitrate_upper
cannam@86:
Specifies the upper limit in a VBR bitstream. If the value matches the bitrate_nominal and bitrate_lower parameters, the stream is fixed bitrate. May be unset if no limit exists.
cannam@86:
bitrate_nominal
cannam@86:
Specifies the average bitrate for a VBR bitstream. May be unset. If the bitrate_upper and bitrate_lower parameters match, the stream is fixed bitrate.
cannam@86:
bitrate_lower
cannam@86:
Specifies the lower limit in a VBR bitstream. If the value matches the bitrate_nominal and bitrate_upper parameters, the stream is fixed bitrate. May be unset if no limit exists.
cannam@86:
bitrate_window
cannam@86:
Currently unset.
cannam@86:
cannam@86:
codec_setup
cannam@86:
Internal structure that contains the detailed/unpacked configuration for decoding the current Vorbis bitstream.
