/**
* @file
* libspeex Speex audio encoder
*
* Usage Guide
* This explains the values that need to be set prior to initialization in
* order to control various encoding parameters.
*
* Channels
* Speex only supports mono or stereo, so avctx->channels must be set to
* 1 or 2.
*
* Sample Rate / Encoding Mode
* Speex has 3 modes, each of which uses a specific sample rate.
* narrowband : 8 kHz
* wideband : 16 kHz
* ultra-wideband : 32 kHz
* avctx->sample_rate must be set to one of these 3 values. This will be
* used to set the encoding mode.
*
* Rate Control
* VBR mode is turned on by setting CODEC_FLAG_QSCALE in avctx->flags.
* avctx->global_quality is used to set the encoding quality.
* For CBR mode, avctx->bit_rate can be used to set the constant bitrate.
* Alternatively, the 'cbr_quality' option can be set from 0 to 10 to set
* a constant bitrate based on quality.
* For ABR mode, set avctx->bit_rate and set the 'abr' option to 1.
* Approx. Bitrate Range:
* narrowband : 2400 - 25600 bps
* wideband : 4000 - 43200 bps
* ultra-wideband : 4400 - 45200 bps
*
* Complexity
* Encoding complexity is controlled by setting avctx->compression_level.
* The valid range is 0 to 10. A higher setting gives generally better
* quality at the expense of encoding speed. This does not affect the
* bit rate.
*
* Frames-per-Packet
* The encoder defaults to using 1 frame-per-packet. However, it is
* sometimes desirable to use multiple frames-per-packet to reduce the
* amount of container overhead. This can be done by setting the
* 'frames_per_packet' option to a value 1 to 8.
