/** struct snd_codec
|
|
* @id: Identifies the supported audio encoder/decoder.
|
|
* See SND_AUDIOCODEC macros.
|
|
* @ch_in: Number of input audio channels
|
|
* @ch_out: Number of output channels. In case of contradiction between
|
|
* this field and the channelMode field, the channelMode field
|
|
* overrides.
|
|
* @sample_rate: Audio sample rate of input data
|
|
* @bit_rate: Bitrate of encoded data. May be ignored by decoders
|
|
* @rate_control: Encoding rate control. See SND_RATECONTROLMODE defines.
|
|
* Encoders may rely on profiles for quality levels.
|
|
* May be ignored by decoders.
|
|
* @profile: Mandatory for encoders, can be mandatory for specific
|
|
* decoders as well. See SND_AUDIOPROFILE defines.
|
|
* @level: Supported level (Only used by WMA at the moment)
|
|
* @ch_mode: Channel mode for encoder. See SND_AUDIOCHANMODE defines
|
|
* @format: Format of encoded bistream. Mandatory when defined.
|
|
* See SND_AUDIOSTREAMFORMAT defines.
|
|
* @align: Block alignment in bytes of an audio sample.
|
|
* Only required for PCM or IEC formats.
|
|
* @options: encoder-specific settings
|
|
* @reserved: reserved for future use
