 I guess this is more of a question to see if it is a bug or not first.
 I am using the latest git.

 Replying to [comment:2 Tjoppen]:
 > What do you expect this to do? UDP is not an application protocol. Are
 you trying to have it upgrade to QUIC? There's a specific mechanism for
 that, but it's far from being standardized.

 Short explanation:
 I expect ffmpeg to start reading from UDP.

 Long explanation:
 This has nothing to do with QUIC. I am using a "load balancer" for my
 input of sort that gives a 302 redirect. This load balancer may return a
 http://, https:// or udp:// address.

 I expect the following to happen;

 If;

 {{{
 ffmpeg -i http://example.com/?ch=X
 }}}
 returns a 302 that looks like this;

 {{{
 location: udp://239.193.0.188:3301?pkt_size=1316
 }}}

 Then I expect ffmpeg to behave as if I had run,


 {{{
 ffmpeg -i udp://239.193.0.188:3301?pkt_size=1316
 }}}

 Do you see the use case?
