3.5.7 Can I turn off network keys and IV updates when using the ESP32 BLE Mesh application?
3.6 Camera application
3.6.1 What type of camera does the ESP32 series chips support?
3.6.2 Where is the factory firmware of ESP-EYE?
3.6.3 Does ESP32 support the camera with a 12-bit DVP interface?
3.6.4 Does ESP32 support acquiring JPEG images using a camera without JEPG encoding?
3.6.5 Can the 2-megapixel OV2640 camera on the ESP-EYE be changed to only output 0.3-
megapixel images?
3.6.6 Does ESP32 support a global shutter camera?
3.6.7 What is the frame rate when ESP32 transfers 1080P video via RTSP using the DVP camera?
3.6.8 ESP32-S3 only supports MJPEG encoding, but H264/H265 format encoding is needed
when implementing rtsp/rtmp streaming. Is there any encoding that supports H264/H265
format?
3.6.9 Does ESP32/ESP32-S3 have a camera that supports wide-angle?
3.6.10 It takes 5 seconds for ESP32-S2 to display the camera image from power-on. Can it be
improved?
3.6.11 Can ESP32 directly provide 24 MHz frequency to GC0308 camera?
3.6.12 Does ESP32/ESP32-S3 support MMS streaming protocol?
3.6.13 When debugging the GC2145 camera with ESP32-S3, the maximum supported resolution
seems to be 1024x768. If it is adjusted to a larger resolution, such as 1280x720, it will
print cam_hal: EV-EOF-OVF error. How to solve this issue?
3.6.14 Does ESP32-S3 support GB28181 protocol?
3.6.15 Is there any reference for ESP32/ESP32-S2/ESP32-S3 to recognize the QR code through
the camera?
3.6.16 When adding the SD-card interface and camera interface for OV5640 sensor, we found
that some pins of different ESP32 drivers conflicted with each other. Please suggest pins
for the camera interface and SD-card interface.
3.6.17 Can a driver for a specific camera model be added if the currently supported camera sensors
do not meet my requirements?
3.6.18 How to add a custom resolution?
3.6.19 How to modify the register configuration of a camera sensor?
3.6.20 What triggers "cam_hal: EV-VSYNC-OVF"in esp32-camera?
