1 month ago Hmm...need to reset state and then resume. It is recommended that the API documentation be more detailed. If the use of a component's external API requires analyzing the source code for correct usage, then this is truly user-unfriendly.
In audio_element_resume()，if its state is FINISHED，it only report a status to event iface. How to resume an element if its state turned into FINISHED?
esp_err_t audio_element_resume(audio_element_handle_t el, float wait_for_rb_threshold, TickType_t timeout) { if (!el->task_run) { ESP_LOGW(TAG, "[%s] Element has not create when AUDIO_ELEMENT_RESUME", el->tag); return ESP_FAIL; } if (el->state == AEL_STATE_RUNNING) { audio_element_report_status(el, AEL_STATUS_STATE_RUNNING); ESP_LOGW(TAG, "[%s] RESUME: Element is already running, state:%d, task_run:%d, is_running:%d", el->tag, el->state, el->task_run, el->is_running); return ESP_OK; } if (el->task_stack <= 0) { el->is_running = true; audio_element_force_set_state(el, AEL_STATE_RUNNING); audio_element_report_status(el, AEL_STATUS_STATE_RUNNING); return ESP_OK; } if (el->state == AEL_STATE_ERROR) { ESP_LOGE(TAG, "[%s] RESUME: Element error, state:%d", el->tag, el->state); return ESP_FAIL; } if (el->state == AEL_STATE_FINISHED) { ESP_LOGW(TAG, "[%s] RESUME: Element has finished, state:%d", el->tag, el->state); audio_element_report_status(el, AEL_STATUS_STATE_FINISHED); return ESP_OK; } if (wait_for_rb_threshold > 1 || wait_for_rb_threshold < 0) { return ESP_FAIL; } int ret = ESP_OK; xEventGroupClearBits(el->state_event, RESUMED_BIT); if (audio_element_cmd_send(el, AEL_MSG_CMD_RESUME) == ESP_FAIL) { ESP_LOGW(TAG, "[%s] Send resume command failed", el->tag); return ESP_FAIL; } EventBits_t uxBits = xEventGroupWaitBits(el->state_event, RESUMED_BIT, false, true, timeout); if ((uxBits & RESUMED_BIT) != RESUMED_BIT) { ESP_LOGW(TAG, "[%s-%p] RESUME timeout", el->tag, el); ret = ESP_FAIL; } else { if (wait_for_rb_threshold != 0 && el->read_type == IO_TYPE_RB) { ret = audio_element_wait_for_buffer(el, rb_get_size(el->in.input_rb) * wait_for_rb_threshold, timeout); } } return ret; }
