Troubleshooting

“Port 1935 is already in use” or the app quits at start

Another copy of StreamPort, or another RTMP server, is using port 1935. Quit the other copy (Cmd+Q) and open StreamPort again. Only one copy can run at a time.

No signal from Wirecast

• Check the address is rtmp://127.0.0.1:1935/live with a stream name, and that you clicked Stream in Wirecast.
• The Activity bar says if a second source was refused because another source is live (for example the camera).

The preview is black or says “Loading preview”

Wait a few seconds after the signal appears. If it stays, turn Live preview off and on in Settings → General.

A destination says Failed

Almost always a wrong stream key or server URL. For Facebook use the RTMPS server. For YouTube make sure the key belongs to a stream that is enabled. Re-copy the key, with no spaces.

A destination keeps reconnecting

Check your upload speed against the total shown in the header. Lower the bitrate in Wirecast, or re-encode that destination at a lower bitrate.

No sound with the virtual camera

A virtual camera carries video only. Choose an audio device in Settings → Source (macOS may ask for microphone permission), or use RTMP, which carries both.

Camera or microphone permission denied

Open System Settings → Privacy & Security → Camera / Microphone and allow StreamPort.

License will not activate

• Paste the whole key, starting with SR1.
• If it says the license is used on two Macs, press Deactivate on one of them.
• Still stuck? Contact support.
