In io/JpegWriter a variable wasn't freed, this bug is already fixed, but the latest version was released before the fix. This causes my program to crash after ca. 50 calls, because every time va. 64 kb get allocated, but never freed. This makes the latest version in Arduino IDE library marketplace unusable. PLEASE UPDATE to new version, where this bug is fixed, so nobody has to waste houurs trying to find out, where memory is lost.
Hello, im getting this error when running any of the code examples on my ESP32 cam.

Rebooting...
I'm really new so at first I was just testing the examples out of the box. Does this error really mean that the camera that comes with my ESP32 microprocessor is not supported or could be something else? how do I know which versions/models/stuff are supported?
Thanks

The workaround for this error is to include the following line at platformio.ini

build_unflags = -Werror=reorder
I'm aware that the ESP Camera can only serve a single connection at any time.
But closing the stream and then trying to reconnect always fails until i reset the ESP.
I'm using the simple HTTPstream example with an AI-Thinker ESP32CAM devkit.
Attempting to reconnect to the server gives no output on the serial debugger.
When running the Video Streaming Server Example for an AI Thinker camera, rather than getting an image on the web page, I get continually scrolling random looking text. It appears that the browser is not being instructed to interpret the output as an image or the image file is improper.
Thoughts?
I think you have to free the allocated memory by fmt2jpg.
after file.write(jpeg, len);
free(jpeg);
