Headers already sent? #1

Hello, I'm running into trouble displaying my stream in VLC using your server, any ideas? I've pasted the code below, it seems like I am able to mount the stream correctly, but then when VLC sends the request it hangs. Any help would be appreciated. See below:

Hi @brennongs, Did you manage to resolve this issue with vlc playback at all?

I'm also having this issue. Using Larix Broadcaster on both Android and iOS to attempt to send an HEVC RTSP stream to the server. Here's my log.

This issue is probably fixed by #5. The describe/setup handlers allowed execution to continue down the success path after the response was sent with an error code.

@brennongs In your case, DESCRIBE wanted to return a 404 because it could not find a mount for the url your client tried. @reedog117 In your case, SETUP wanted to return a 504 because your client requested TCP, which this project doesn't support.

Either way, I'm having another issue with VLC playback now: #4

This should be resolved now - please re-open if it isn't!
