If the + sd card cannot take all that data, then the camera will be idle waiting for the sd. Lower the framesize (UXGA -> SVGA), + and lower the quality (10 -> 15 -> 20, higher number is lower quality) to improve framerate to the camera limits. + If you have a fast enough sd card, it will record at the full speed of the camera. + + You can look at the blinking red led on the back of the chip to see the recording rate -- sd chips for video are made to be more predictable. + + The files will have the name such as: + + desklens10.003.avi + + "desklens" is your devname + 10 - is a number stored in eprom that will increase everytime your device boots + 3 - is the 3rd file created during the current boot + + Small red led on the back blinks with every frame. + + + by James Zahary Sep 12, 2020 + jamzah.plc@gmail.com + + - v09 Sep 24, 2020 + - v10 Sep 28, 2020 + + https://github.com/jameszah/ESP32-CAM-Video-Recorder-junior + https://github.com/jameszah/ESP32-CAM-Video-Recorder + + jameszah/ESP32-CAM-Video-Recorder is licensed under the + GNU General Public License v3.0 + + jameszah/ESP32-CAM-Video-Recorder-junior is licensed under the + GNU General Public License v3.0 + + The is Arduino code, with standard setup for ESP32-CAM + - Board ESP32 Wrover Module + - Partition Scheme Huge APP (3MB No OTA) + + Compiled with Arduino 1.8.12, which used these libraries: + + Using library SD_MMC at version 1.0 in folder: C:\Users\James\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\SD_MMC + Using library FS at version 1.0 in folder: C:\Users\James\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\FS + Using library EEPROM at version 1.0.3 in folder: C:\Users\James\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\EEPROM + Using library WiFi at version 1.0 in folder: C:\Users\James\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\WiFi + Using library ESPmDNS at version 1.0 in folder: C:\Users\James\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\ESPmDNS + Using library HTTPClient at version 1.2 in folder: C:\Users\James\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\HTTPClient + Using library WiFiClientSecure at version 1.0 in folder: C:\Users\James\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.4\libraries\WiFiClientSecure + +*/ + +//#define LOG_LOCAL_LEVEL ESP_LOG_VERBOSE +#include "esp_log.h" +#include "esp_http_server.h" +#include "esp_camera.h" + +//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +// user edits here: + +static const char vernum[] = "v11";
