Unable to open preview UDP stream

[ramzesko]

Hi,
I'm using GoPro Hero 13 Black and struggling with implementation of preview feature. Enabling preview with HTTP command seems to work properly but I'm unable to verify because UDP stream is not opening in VLC. I've tried the default 8554 port, 8556 and others in both CoHN mode and camera network with IP 10.5.5.9 - every time without success.

Could you provide an example of proper url to use with VLC or right ffmpeg command? I've seen that it should work in CoHN mode completely fine Issue #601

You can view the Preview Stream in VLC at udp://@:8554.

In the PR linked here, I updated the preview stream demo to print this to console, and also wait for the user to open VLC since once the demo uses OpenCV to display the stream it is no longer viewable in VLC.
