Porting arduino-esp32 CameraWebServer to https

[jov58]

Describe Your Goal Running the standard ESP32 CameraWebServer example on an https webserver.

What Does Your Project Look Like The same as the official example except including esp_https_server instead of esp_http_server and changes in startCameraServer(), see below.

ESP32 Module TTGO Camera Plus

Software (please complete the following information if applicable)

• Visual Studio Code with latest Arduino Core and PlatformIO

Additional context

To run the CameraWebServer on https, I have changed the startCameraServer() function as follows:

void startCameraServer(){
#ifndef _ESP_HTTPS_SERVER_H_
  httpd_config_t config = HTTPD_DEFAULT_CONFIG();
#else
  httpd_ssl_config config = HTTPD_SSL_CONFIG_DEFAULT();
  config.cacert_len = cert->getCertLength();
  config.cacert_pem = cert->getCertData();
  config.prvtkey_len = cert->getPKLength();
  config.prvtkey_pem = cert->getPKData();
#endif
  httpd_uri_t index_uri = { .uri = "/", .method = HTTP_GET, .handler = index_handler, .user_ctx = NULL };
  httpd_uri_t status_uri = { .uri = "/status", .method = HTTP_GET, .handler = status_handler, .user_ctx = NULL };
  httpd_uri_t cmd_uri = { .uri = "/control", .method = HTTP_GET, .handler = cmd_handler, .user_ctx = NULL };
  httpd_uri_t capture_uri = { .uri = "/capture", .method = HTTP_GET, .handler = capture_handler, .user_ctx = NULL };
  httpd_uri_t stream_uri = { .uri = "/stream", .method = HTTP_GET, .handler = stream_handler, .user_ctx = NULL };

  ra_filter_init(&ra_filter, 20);
    
  mtmn_config.type = FAST;
  mtmn_config.min_face = 80;
  mtmn_config.pyramid = 0.707;
  mtmn_config.pyramid_times = 4;
  mtmn_config.p_threshold.score = 0.6;
  mtmn_config.p_threshold.nms = 0.7;
  mtmn_config.p_threshold.candidate_number = 20;
  mtmn_config.r_threshold.score = 0.7;
  mtmn_config.r_threshold.nms = 0.7;
  mtmn_config.r_threshold.candidate_number = 10;
  mtmn_config.o_threshold.score = 0.7;
  mtmn_config.o_threshold.nms = 0.7;
  mtmn_config.o_threshold.candidate_number = 1;
   
  face_id_init(&id_list, FACE_ID_SAVE_NUMBER, ENROLL_CONFIRM_TIMES);
    
#ifndef _ESP_HTTPS_SERVER_H_
  Serial.printf("Starting web server on port: '%d'\n", config.server_port);
  if (httpd_start(&camera_httpd, &config) == ESP_OK) {
#else
  Serial.printf("Starting web server on port: '%d'\n", config.port_secure);
  if (httpd_ssl_start(&camera_httpd, &config) == ESP_OK) {
#endif
    httpd_register_uri_handler(camera_httpd, &index_uri);
    httpd_register_uri_handler(camera_httpd, &cmd_uri);
    httpd_register_uri_handler(camera_httpd, &status_uri);
    httpd_register_uri_handler(camera_httpd, &capture_uri);
  }

#ifndef _ESP_HTTPS_SERVER_H_
  config.server_port += 1;
  config.ctrl_port += 1;
  Serial.printf("Starting stream server on port: '%d'\n", config.server_port);
  if (httpd_start(&stream_httpd, &config) == ESP_OK) {
#else
  config.port_secure += 1;
  config.httpd.ctrl_port += 1;
  Serial.printf("Starting stream server on port: '%d'\n", config.port_secure);
  if (httpd_ssl_start(&stream_httpd, &config) == ESP_OK) {
#endif
    httpd_register_uri_handler(stream_httpd, &stream_uri);
  }
}

If I include esp_http_server.h the original code will compile and everything runs fine. If I include esp_https_server.h my changes will compile and the webserver nicely comes up at port 443. The menu shows and I can get a still from the camera. The only thing that doesn't work is what it's all about: the live stream. The window shows but only with a broken image icon. I see no messages in the terminal window in PlatformIO or anything in the browser.

Any ideas how to get this working?

@jov58: This is probably not the correct forum to ask about this, as you are using the web server library from Espressif. This repository is for a completely different HTTP server with a totally different API.

My current project is to port that camera example to this web server (issue #138), but I haven't quite gotten it to work yet.
