[udp @ 0x7f7a340032c0] attempted to set receive buffer to size 104857600 but it only ended up set as 33554432

buffer_size=size
Set the maximum UDP socket buffer size in bytes.
fifo_size=units
Set the UDP receiving circular buffer size, expressed as a number of packets with size of 188 bytes. If not specified defaults to 7*4096.
overrun_nonfatal=1|0
Survive in case of UDP receiving circular buffer overrun. Default value is 0.
