ESP32-LyraT-Mini_V1.2 运行例程 OPUS编码无法重采样无法设置为单声道

[usKNOW]

Code: Select all

    rsp_filter_cfg_t rsp_file_cfg = DEFAULT_RESAMPLE_FILTER_CONFIG();
    rsp_file_cfg.src_rate = SAMPLE_RATE;
    rsp_file_cfg.src_ch = 2;
    rsp_file_cfg.dest_rate = SAMPLE_RATE;
    rsp_file_cfg.dest_ch = 1;
    rsp_file_cfg.complexity = 0; 
    rsp_file_cfg.down_ch_idx = 1;
    audio_element_handle_t resample = rsp_filter_init(&rsp_file_cfg);

重采样处设置为单声道后，程序直接无法运行。大伙有遇到这种情况吗？求指点一二！！！！
