Stream esp-32 camera to RMTP server like YouTube

I am doing research for a project in which I need to play with camera streams. After multiple hit and trails and googling I am not getting even close to the solution for streaming ESP-32 Camera stream to my own RMTP server directly.

Already tried solutions:

  1. I have tried re-streaming of ESP-32-cam with Raspberry pi, that works well but not something I am looking for

  2. ESP-32-cam: Record and FTP transfer with time triggers (Not tried but believed that it is not a good approach).

Please note: I am not looking at the solution in which ESP-32 cam acts as stream server and browser can connect to it like : https://www.hackster.io/BnBe_Club/9-rtsp-video-streamer-using-the-esp32-cam-board-8832b4

I have already tried it and it works well but not for the usecase which involves streaming to RTMP server without restreaming.

On google, I found a similar thread : https://forum.arduino.cc/index.php?topic=634605.0 The guy with solution is not interested in sharing it.

may be some modification required in below code MAY BE ref: GitHub - espressif/esp32-camera

static esp_err_t stream_handler(httpd_req_t *req){
camera_fb_t * fb = NULL;
esp_err_t res = ESP_OK;
size_t _jpg_buf_len = 0;
uint8_t * _jpg_buf = NULL;
char * part_buf[64];

res = httpd_resp_set_type(req, _STREAM_CONTENT_TYPE);
if(res != ESP_OK){
return res;
}

while(true){
fb = esp_camera_fb_get();
if (!fb) {
Serial.println("Camera capture failed");
res = ESP_FAIL;
} else {
if(fb->width > 400){
if(fb->format != PIXFORMAT_JPEG){
bool jpeg_converted = frame2jpg(fb, 80, &_jpg_buf, &_jpg_buf_len);
esp_camera_fb_return(fb);
fb = NULL;
if(!jpeg_converted){
Serial.println("JPEG compression failed");
res = ESP_FAIL;
}
} else {
_jpg_buf_len = fb->len;
_jpg_buf = fb->buf;
}
}
}
if(res == ESP_OK){
size_t hlen = snprintf((char *)part_buf, 64, _STREAM_PART, _jpg_buf_len);
res = httpd_resp_send_chunk(req, (const char *)part_buf, hlen);
}
if(res == ESP_OK){
res = httpd_resp_send_chunk(req, (const char *)_jpg_buf, _jpg_buf_len);
}
if(res == ESP_OK){

}
