RTSP not Playing in VLCKit

[chrisfauerbach]

Hello all! I'm trying to write a very basic application using VLCKit for a Mac OS application. XCode, Mac OS 10.13, etc.

I can use the bunny URL without issue, audio and video show just fine:

Name output is: https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4

Yet, when I run against an RTSP feel, I get some output in the standard out, but no audio/video

Name output is: rtsp://192.168.10.12:554/2

Any thoughts?

Does playing your stream work with the official macOS VLC app?

[chrisfauerbach]

It does! I should have specified that in the first place. My apologies.

I'm new to Mac OS development (but a 20 year developer).. so I very well may be doing something stupid, but I'm pretty sure I'm not

Just tried my app and VLC against this too, no issues in the VLC app, same behavior in mine.

Figured it out! Debug logs for the win!

My app didn't have network server permissions. Once set, all was good!
