I want to build a MJPEG server via websocket on esp32 in esp idf
The problem is that I am using the mongoose network stack, and `I have to know exactly how would the ws header look like `
After some searching, I found that I need data:image/jpeg;base64,
and I did this :
“` mg_ws_printf(c, WEBSOCKET_OP_TEXT, “data:image/jpeg;base64,”);
mg_ws_send(c, frame_buf->buf, frame_buf->len,WEBSOCKET_OP_BINARY);
mg_ws_send(c, “\r\n”, 2,WEBSOCKET_OP_TEXT);“`
unfortunately, nothing shows up. I have to mention that the basic text communication and the frame read are functioning
thanks I solved it
“` if (frame_buf->buf != NULL)
{
size_t count = mg_ws_printf(c, WEBSOCKET_OP_TEXT, “Content-Type: image/jpeg Content-Length: %lu\r\n\r\n”, frame_buf->len);
ESP_LOGI(TAG,”count : %d”,count);
count = mg_ws_send(c, frame_buf->buf, frame_buf->len,WEBSOCKET_OP_BINARY);
ESP_LOGI(TAG,”count2 : %d”,count);
vTaskDelay(500/portTICK_PERIOD_MS);
esp_camera_fb_return(frame_buf);
} “`
