/** 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 in Hz, use values like 48000 |
|
* for this. |
|
* @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 |
