调用esp-adf 出现MP3_DE_LIB: pvmp3_framedecoder.cpp:701 (pvmp3_InitDecoder): Memory exhausted

调用esp-adf 出现MP3_DE_LIB: pvmp3_framedecoder.cpp:701 (pvmp3_InitDecoder): Memory exhausted
加大了MP3的stack size也是出现Memory exhausted的问题！求助各位专家，我的问题如何解决呢？
我的工程设置如下：
使用 ADF 进行VTT（voice to text），之后text发到minimax进行ai大模型交互，返回的txt由百度在线语音合成 (text-to-speech, TTS) 服务生成的音频通过i2s送到音频codec进行播放。
使用的是兼容ESP32_S3_KORVO2_V3_BOARD 板卡，模组是ESP32-S3-WROOM-1，ESP-IDF用的版本是5.2.2，ESP-ADF用的最新的。
工程我放到了gitee上，可以编译下载，https://gitee.com/robot3g/ai_toys，麻烦各位专家帮忙看一下问题！在线等！
初始化函数如下：
baidu_tts_handle_t baidu_tts_init(baidu_tts_config_t *config)
{
// 管道设置
audio_pipeline_cfg_t pipeline_cfg = DEFAULT_AUDIO_PIPELINE_CONFIG();
baidu_tts_t *tts = calloc(1, sizeof(baidu_tts_t));
AUDIO_MEM_CHECK(TAG, tts, return NULL);
tts->pipeline = audio_pipeline_init(&pipeline_cfg);
tts->buffer_size = config->buffer_size;
if (tts->buffer_size <= 0) {
tts->buffer_size = DEFAULT_TTS_BUFFER_SIZE;
}
tts->buffer = malloc(tts->buffer_size);
AUDIO_MEM_CHECK(TAG, tts->buffer, goto exit_tts_init);
tts->sample_rate = config->playback_sample_rate;
// I2S流设置
i2s_stream_cfg_t i2s_cfg = I2S_STREAM_CFG_DEFAULT_WITH_PARA(0, 16000, 16, AUDIO_STREAM_WRITER);
i2s_cfg.std_cfg.slot_cfg.slot_mode = I2S_SLOT_MODE_MONO;
i2s_cfg.std_cfg.slot_cfg.slot_mask = I2S_STD_SLOT_LEFT;
tts->i2s_writer = i2s_stream_init(&i2s_cfg);
// http流设置
http_stream_cfg_t http_cfg = {
.type = AUDIO_STREAM_READER,
.event_handle = _http_stream_reader_event_handle,
.user_data = tts,
.task_stack = BAIDU_TTS_TASK_STACK,
};
tts->http_stream_reader = http_stream_init(&http_cfg);
// MP3流设置
mp3_decoder_cfg_t mp3_cfg = DEFAULT_MP3_DECODER_CONFIG();
tts->mp3_decoder = mp3_decoder_init(&mp3_cfg);
audio_pipeline_register(tts->pipeline, tts->http_stream_reader, "tts_http");
audio_pipeline_register(tts->pipeline, tts->mp3_decoder, "tts_mp3");
audio_pipeline_register(tts->pipeline, tts->i2s_writer, "tts_i2s");
const char *link_tag[3] = {"tts_http", "tts_mp3", "tts_i2s"};
audio_pipeline_link(tts->pipeline, &link_tag[0], 3);
// I2S流采样率 位数等设置
i2s_stream_set_clk(tts->i2s_writer, config->playback_sample_rate, 16, 1);
return tts;
exit_tts_init:
baidu_tts_destroy(tts);
return NULL;
}

加大了MP3的stack size也是出现Memory exhausted的问题！求助各位专家，我的问题如何解决呢？
我的工程设置如下：
使用 ADF 进行VTT（voice to text），之后text发到minimax进行ai大模型交互，返回的txt由百度在线语音合成 (text-to-speech, TTS) 服务生成的音频通过i2s送到音频codec进行播放。
使用的是兼容ESP32_S3_KORVO2_V3_BOARD 板卡，模组是ESP32-S3-WROOM-1，ESP-IDF用的版本是5.2.2，ESP-ADF用的最新的。
工程我放到了gitee上，可以编译下载，https://gitee.com/robot3g/ai_toys，麻烦各位专家帮忙看一下问题！在线等！
初始化函数如下：
baidu_tts_handle_t baidu_tts_init(baidu_tts_config_t *config)
{
// 管道设置
audio_pipeline_cfg_t pipeline_cfg = DEFAULT_AUDIO_PIPELINE_CONFIG();
baidu_tts_t *tts = calloc(1, sizeof(baidu_tts_t));
AUDIO_MEM_CHECK(TAG, tts, return NULL);
tts->pipeline = audio_pipeline_init(&pipeline_cfg);
tts->buffer_size = config->buffer_size;
if (tts->buffer_size <= 0) {
tts->buffer_size = DEFAULT_TTS_BUFFER_SIZE;
}
tts->buffer = malloc(tts->buffer_size);
AUDIO_MEM_CHECK(TAG, tts->buffer, goto exit_tts_init);
tts->sample_rate = config->playback_sample_rate;
// I2S流设置
i2s_stream_cfg_t i2s_cfg = I2S_STREAM_CFG_DEFAULT_WITH_PARA(0, 16000, 16, AUDIO_STREAM_WRITER);
i2s_cfg.std_cfg.slot_cfg.slot_mode = I2S_SLOT_MODE_MONO;
i2s_cfg.std_cfg.slot_cfg.slot_mask = I2S_STD_SLOT_LEFT;
tts->i2s_writer = i2s_stream_init(&i2s_cfg);
// http流设置
http_stream_cfg_t http_cfg = {
.type = AUDIO_STREAM_READER,
.event_handle = _http_stream_reader_event_handle,
.user_data = tts,
.task_stack = BAIDU_TTS_TASK_STACK,
};
tts->http_stream_reader = http_stream_init(&http_cfg);
// MP3流设置
mp3_decoder_cfg_t mp3_cfg = DEFAULT_MP3_DECODER_CONFIG();
tts->mp3_decoder = mp3_decoder_init(&mp3_cfg);
audio_pipeline_register(tts->pipeline, tts->http_stream_reader, "tts_http");
audio_pipeline_register(tts->pipeline, tts->mp3_decoder, "tts_mp3");
audio_pipeline_register(tts->pipeline, tts->i2s_writer, "tts_i2s");
const char *link_tag[3] = {"tts_http", "tts_mp3", "tts_i2s"};
audio_pipeline_link(tts->pipeline, &link_tag[0], 3);
// I2S流采样率 位数等设置
i2s_stream_set_clk(tts->i2s_writer, config->playback_sample_rate, 16, 1);
return tts;
exit_tts_init:
baidu_tts_destroy(tts);
return NULL;
}
