Hi,

looks like Micro-RTSP is not compatible with the latest version of ESP32 Core.

To fix:

1. Goto C:\Users<username>\AppData\Local\Arduino15\packages\esp32\hardware\esp32<version>

2. Make a copy of platform.txt and rename it to platform.local.txt.

3. Open platform.txt. Change

4. Restart Arduino IDE !!!!
