ESP32-CAM-Video-Recorder-junior
This program records an mjpeg avi video to the sd card of an ESP32-CAM.
It is the junior version of https://github.com/jameszah/ESP32-CAM-Video-Recorder
which has 100 other features of wifi, streaming video, http control, telegram updates, pir control,
touch control, ftp downloads, .... and other things that make it very big and complex.
This one is written in simple arduino code without any semaphores, tasks, priorities, RTOS stuff ....
Just set a few parameters, compile and download, and it will record on power-on, until sd is full, or power-off.
Then pull out the sd and move it to your computer, and you will see all but the last file avi which died during the unplug.
Compile Time Parameters
1. framesize 10,9,7,6,5 for 10 - UXGA (1600x1200 @ 6 fps),
9 - SXGA (1280x1024 @ 6 fps),
7 - SVGA(800x600 @ 24 fps),
6 - VGA(640x480 @ 24 fps),
5 - CIF(400x296 @ 50 fps)
2. quality - 1 to 63 - 10 is a good start, increase to 20 to get more frames per second - must be higher than jpeg_quality below
3. avi_length - seconds for each avi - it closes files, and starts another file after this time - like 60 or 1800
4. devname - a text name for your camera when the files are on your computer
5. If you want internet, set #define IncludeInternet to 1, and put in your ssid and password
If you hold down gpio 12 - the files will be closed, and recording stopped. Web interface still running.
If you hold down gpio 13 during a movie start - it will record at UXGA 6 fps, rather than SVGA 25 fps.
Note that framesize and high quality will produce lots of bytes which have to written to the sd. Those frame rates above are
for the OV2640 camera, and your sd card will have to be able to swallow all that data before the next frame. 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.
