Question

안녕하세요!! esp32-cam 모듈로 웹소켓을 이용한 실시간 스트리밍을 해보려고하는데 esp를 웹소켓 서버로 두고 데이터를 보내면 실시간으로 잘 보이더라고요!! 지연이 0.1초도 안돼는 것 같아요 데이터도 초당 10개 가까이 송신 되고요! 그런데 esp를 클라로 두고 gcp vm에 서버를 따로 만들어서 서버로 데이터 송신하는건 초당 1개도 안나가더라고요! 서버쪽은 테스트해보니 더큰 이미지도 초당 20개 이상 잘 받더라고요! 머가 문제일까요?? 코드는 아래 링크하겠습니다.esp를 서버로 하는 코드 http://www.iotsharing.com/2020/03/demo-48-using-websocket-for-camera-live.html#include "esp_camera.h" #include #include #define PWDN_GPIO_NUM 32 #define RESET_GPIO_NUM -1 #define XCLK_GPIO_NUM 0 #define SIOD_GPIO_NUM 26 #define SIOC_GPIO_NUM 27 #define Y9_GPIO_NUM 35 #define Y8_GPIO_NUM 34 #define Y7_GPIO_NUM 39 #define Y6_GPIO_NUM 36 #define Y5_GPIO_NUM 21 #define Y4_GPIO_NUM 19 #define Y3_GPIO_NUM 18 #define Y2_GPIO_NUM 5 #define VSYNC_GPIO_NUM 25 #define HREF_GPIO_NUM 23 #define PCLK_GPIO_NUM 22 WebSocketsServer webSocket = WebSocketsServer(81); WiFiServer server(80); uint8_t cam_num; bool connected = false; String index_html = " \ \ WebSockets Client \ \ \ \ \ \ \ "; void configCamera(){ camera_config_t config; config.ledc_channel = LEDC_CHANNEL_0; config.ledc_timer = LEDC_TIMER_0; config.pin_d0 = Y2_GPIO_NUM; config.pin_d1 = Y3_GPIO_NUM; config.pin_d2 = Y4_GPIO_NUM; config.pin_d3 = Y5_GPIO_NUM; config.pin_d4 = Y6_GPIO_NUM; config.pin_d5 = Y7_GPIO_NUM; config.pin_d6 = Y8_GPIO_NUM; config.pin_d7 = Y9_GPIO_NUM; config.pin_xclk = XCLK_GPIO_NUM; config.pin_pclk = PCLK_GPIO_NUM; config.pin_vsync = VSYNC_GPIO_NUM; config.pin_href = HREF_GPIO_NUM; config.pin_sscb_sda = SIOD_GPIO_NUM; config.pin_sscb_scl = SIOC_GPIO_NUM; config.pin_pwdn = PWDN_GPIO_NUM; config.pin_reset = RESET_GPIO_NUM; config.xclk_freq_hz = 20000000; config.pixel_format = PIXFORMAT_JPEG; config.frame_size = FRAMESIZE_QVGA; config.jpeg_quality = 9; config.fb_count = 1; esp_err_t err = esp_camera_init(&config); if (err != ESP_OK) { Serial.printf("Camera init failed with error 0x%x", err); return; } } void liveCam(uint8_t num){ //capture a frame camera_fb_t * fb = esp_camera_fb_get(); if (!fb) { Serial.println("Frame buffer could not be acquired"); return; } //replace this with your own function webSocket.sendBIN(num, fb->buf, fb->len); //return the frame buffer back to be reused esp_camera_fb_return(fb); } void webSocketEvent(uint8_t num, WStype_t type, uint8_t * payload, size_t length) { switch(type) { case WStype_DISCONNECTED: Serial.printf("[%u] Disconnected!

Oh! Thank you for sharing the information. I learned a lot of new information that I never knew before. Papa's freezeria
