贴一下 你的 pause / resume 的代码看一下
//这是我的pause和resume的代码
//这是暂停和继续的函数，我在LVGL的UI界面中调用它们 void player_pause(player_handle_t player) { if(audio_element_get_state(player->i2s_stream_writer) == AEL_STATE_RUNNING) { audio_pipeline_pause(player->pipeline); } }
void player_resume(player_handle_t player) { if(audio_element_get_state(player->i2s_stream_writer) == AEL_STATE_PAUSED) { audio_pipeline_resume(player->pipeline); } }
//link顺序是file->decoder->filter->i2s
//调试发现 //函数audio_event_iface_cmd可以发送所有element暂停消息到队列中 //但函数audio_event_iface_waiting_cmd_msg 只读取到了file和i2s的暂停消息 esp_err_t audio_event_iface_waiting_cmd_msg(audio_event_iface_handle_t evt) { audio_event_iface_msg_t msg; if (evt->internal_queue && (xQueueReceive(evt->internal_queue, (void *)&msg, evt->wait_time) == pdTRUE)) { if (evt->on_cmd) { ESP_LOGW(TAG, "xQueueReceive msg_source[%d] on_cmd[%d]", msg.source_type, evt->on_cmd); return evt->on_cmd((void *)&msg, evt->context); } } return ESP_OK; }
esp_err_t audio_event_iface_cmd(audio_event_iface_handle_t evt, audio_event_iface_msg_t *msg) { if (evt->internal_queue && (xQueueSend(evt->internal_queue, (void *)msg, 0) != pdPASS)) { ESP_LOGW(TAG, "There are no space to dispatch queue"); return ESP_FAIL; } ESP_LOGW(TAG, "xQueueSend msg_source[%d] on_cmd[%d]", msg->source_type, evt->on_cmd); return ESP_OK; }
