| <dl> |
| <dt><i>version</i></dt> |
| <dd>Vorbis encoder version used to create this bitstream.</dd> |
| <dt><i>channels</i></dt> |
| <dd>Int signifying number of channels in bitstream.</dd> |
| <dt><i>rate</i></dt> |
| <dd>Sampling rate of the bitstream.</dd> |
| <dt><i>bitrate_upper</i></dt> |
| <dd>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.</dd> |
| <dt><i>bitrate_nominal</i></dt> |
| <dd>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.</dd> |
| <dt><i>bitrate_lower</i></dt> |
| <dd>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.</dd> |
| <dt><i>bitrate_window</i></dt> |
| <dd>Currently unset.</dd> |
| |
| <dt><i>codec_setup</i></dt> |
| <dd>Internal structure that contains the detailed/unpacked configuration for decoding the current Vorbis bitstream.</dd> |
