avformat_open_input hangs on non-existent RTSP url

[Max]

I use the 4.2.3 build for Windows in 64Bits

When I use avformat_open_input on a non existant rtsp url it hangs all my code because they are no call back in this case.

Work very good on a working rtsp url, return a callback if the url are malformed but hangs if the url is good formed like : rtsp://login:password@192.168.0.67:554 but do not exist.

For exemple, if this url work and exist : rtsp://login:password@192.168.0.68:554
this will hangs because the good adress are in "554" : rtsp://login:password@192.168.0.68:553

It's a real issue for me because I don't see how to properly make this working wihout a callback from avformat_open_input.

I noticed the same hangs if I have "" in the password, but the first issues is more critical.

Thank you in advance and excuse me if I do a error.

the caracters that hangs the function too in password field are slashs. Think it can be normal but my cam had slash in the passwords...

Please test current FFmpeg git head - the only version supported on this bug tracker - and provide the command line you tested together with the complete, uncut console output to make this a valid ticket.

Excuse my bad english, "command line" so I have to use the static version ? But I use the ffmpeg lib in shared. I'm not on the good place for this reporting ? Or I have to compile the shared lib myself to post the issue ? I download the build on your official link -> ​https://ffmpeg.zeranoe.com/builds/

I see that the same issue for UDP was post and fixed 2 years ago.
I tested on the last build shared/dev for windows 64bits from the 27-07-2020
