If you want to feed some UDP players, you need to send 1316 bytes lenght packets (highest 7xTS below usual MTU=1500). This is very easy to try, just adding the option "pkt_size" in your UDP url, this way udp://192.168.1.43:12345?pkt_size=1316. However once I did it, I had a wrong response on my UDP player. UDP packets are always sent with a size lower than the ethernet MTU (1500 bytes), otherwise fragmentation is quietly activated by the OS and performance decreases ( see here) UDP packets contain RTP frames; hence RTP frames are built by the publisher (ffmpeg) in a way not to exceed the (1500 bytes - UDP header) threshold. reginald davisApr 02, 2015 · Since UDP does not guarantee delivery, this packet simply gets truncated (or dropped) depending on the implementation.
