ESP32-CAM_sd_speed_test
This program tests the speed of the ESP32-CAM SD Writer.
Take 2 picture per avi, and reuses the 2nd picture for entire movie without running the camera.
You can set framezie and quality for you situation.
*****
*
* Sep 15 Quick mod to write a mjpeg file rather than an avi.
* - no headers, no index, no sense of interframe time
* - just plays on computer as fast as it cam
*
*
*
****
edit changes to
- config.frame_size = FRAMESIZE_CIF; // UXGA, SVGA, CIF, etc
- config.jpeg_quality = 1; // 1 to 63 - smaller number is higher quality and more data
... and then the results on the serial monitor, every 100 frames - with avg framesize for last 100.
Small red led on the back blinks with every frame.
