- * Encode an audio frame from samples into buf.

- * @deprecated Use avcodec_encode_audio2 instead.
- *
- * @note The output buffer should be at least FF_MIN_BUFFER_SIZE bytes large.
- * However, for codecs with avctx->frame_size equal to 0 (e.g. PCM) the user
- * will know how much space is needed because it depends on the value passed
- * in buf_size as described below. In that case a lower value can be used.
- *
- * @param avctx the codec context
- * @param[out] buf the output buffer
- * @param[in] buf_size the output buffer size
- * @param[in] samples the input buffer containing the samples
- * The number of samples read from this buffer is frame_size*channels,
- * both of which are defined in avctx.
- * For codecs which have avctx->frame_size equal to 0 (e.g. PCM) the number of
- * samples read from samples is equal to:
- * buf_size * 8 / (avctx->channels * av_get_bits_per_sample(avctx->codec_id))
- * This also implies that av_get_bits_per_sample() must not return 0 for these
- * codecs.
- * @return On error a negative value is returned, on success zero or the number
- * of bytes used to encode the data read from the input buffer.
