LWIP MULTICAST EXAMPLE
Description:
Join multicast group of 224.0.0.251 and listen on port 5353.
Send packet with the content of received packet to multicast group of 224.0.0.251.
Configuration:
[lwipopts.h]
#define LWIP_UDP 1
#define LWIP_IGMP 1
[platform_opts.h]
#define CONFIG_EXAMPLE_MCAST 1
Execution:
Can make automatical Wi-Fi connection when booting by using wlan fast connect example.
A multicast example thread will be started automatically when booting.

THis is an example for USB Video Capture specifically for motion-jpeg capturing.
Please MAKE SURE to reserve enough heap size for UVC by raising configTOTAL_HEAP_SIZE in freeRTOSconfig.h & turning off some functions (e.g. WPS, JDSMART, ATcmd for internal and system) since image frame storing could consume quite large memory space.
TO switch on UVC example, make sure CONFIG_USB_EN is enabled (in platform_autoconf.h) & set CONFIG_EXAMPLE_UVC to 1 (in platform_opts.h).
TO combine uvc with rtsp server, make sure wlan module is enabled & set UVC_WLAN_TRANSFER to 1 (in example_uvc.h).
