Hi there,
I am dealing with issues of video latency / slow motion when running a build of QGC on a Pi 5. If you have had any similar issues, or have build instructions for this platform, I would love to know! Just putting this out here so the community can get together and improve the software for more platforms.
For more details including build instructions and gstreamer scripts, here is my github issue: Videostreaming delay issues on an ARM64 build of QGC for Raspberry Pi · Issue #12199 · mavlink/qgroundcontrol · GitHub
