 I am unsure if this is a bug or if it acts as it should be.
 I have a use case where I use,


 {{{
 ffmpeg -i http://example.com/?ch=X
 }}}

 Which returns a 302 redirect to "udp://X:Y?pkt_size=1316"


 {{{
 * Connection state changed (MAX_CONCURRENT_STREAMS == 128)!
 < HTTP/2 302
 < server: nginx
 < date: Wed, 29 Apr 2020 08:10:09 GMT
 < content-type: text/html
 < location: udp://239.193.0.188:3301?pkt_size=1316
 < access-control-allow-origin: *
 }}}

 The issue right now is that ffmpeg will try to establish a TCP connection
 (because the initial http connection was TCP).

 Should a redirect of this kind work and then pull the input from udp:// ?
