Unable to receive H265 stream

[joaoantoniocardoso]

Expected Behavior

QGC should handle the documented "udph265" URI scheme also when received via MAVLink, or it should accept H265 via regular "udp" scheme.

Current Behavior

QGC fails to parse stream URIs using the "udph265" URI scheme.

Steps to Reproduce:

Using mavlink-camera-manger's new H265 feature (available since t3.17.0).

1. Create a fake/ball h265 stream using the udp265://0.0.0.0:5600 endpoint:
   
   

2. Open QGC and check the console:

VideoManagerLog: Configure primary stream: "udp265://192.168.2.1:5600"
VideoManagerLog: New Video URI  "udp://0.0.0.0:udp265://192.168.2.1:5600"
