QGroundControl Crashes with H.265 Stream When AutoConnect is Enabled about qgroundcontrol HOT 4 OPEN

Could you enable extra GStreamer debugging in the console and see if it is the same error as in #11244? Has to do with the udpsrc buffer size. I wonder if only udp related autoconnect settings are affecting this for you. We are forced to use an older gstreamer on linux only and maybe that is part of the problem. Maybe I can install Ubuntu 24.04 and try it.

@HTRamsey Hello! Thank you for your response.
It seems to me that in this case, the GStreamer logs won't provide much information.
If you still need to get this information, I can provide it. Here is a more detailed description of the problem I encountered:

1. pymavlink doesn't have a native H265 type, so I'm using mavlink.VIDEO_STREAM_TYPE_RTPUDP.
   

2. As a result, when QGroundControl retrieves the stream information and tries to parse it, the following issue occurs:

In src/VideoManager/VideoManager.cc - QGC sets the prefix "udp://" for the H265 stream, which later causes a crash because the H265 stream is attempted to be read as H264

Additional stream info:

I would appreciate your help and a prompt resolution to the issue.

@HTRamsey Hello!
Are there any updates regarding this bug?
Thank you!

I will look into it deeper over this weekend/next week considering the extra info you provided. GStreamer isn't my expertise so it depends a little bit on if the problem is just QGC setting video up or an actual GStreamer configuration problem. In the worst case scenario, I have another PR that will introduce QtMultimedia as an alternative Video Player (which will use FFMPEG) and that should hopefully resolve the problem with all of the same functionality.
