동영상 스트리밍 (보조 컴퓨터/QGroundControl)

PX4-based vehicles support video streaming using a camera connected to a companion computer.

INFO

You can't video stream directly from a camera connected to PX4.

GStreamer is used to send the video to QGroundControl over an IP link. To support streaming use cases you will need to install GStreamer development packages on both your companion computer and on the system running QGroundControl. QGroundControl uses GStreamer 1.14.4 and a stripped down version of QtGstreamer to support UDP RTP and RSTP video streaming.

General instructions for installing GStreamer and starting the stream on a companion computer are provided in the QGroundControl VideoReceiver README.

The setup of cameras and data links depends on many factors. Examples in this library are listed below (note, these are options, not "recommended"):

• Video Streaming using WFB-ng Wifi (Tutorial): Using RPi and WiFi module in unconnected (broadcast) mode to stream video and as a bidirectional telemetry link.

QGC 설정

QGC로 비디오 스트리밍을 설정하고 사용하려면 :

1. QGC를 실행하기 전에 GStreamer를 설치하십시오. Ubuntu에서는 아래의 명령어로 설치합니다.

   sudo apt install gstreamer1.0-plugins-bad gstreamer1.0-libav gstreamer1.0-gl -y

   For other platforms follow the instructions in QGroundControl VideoReceiver README.

2. Enable video in Fly View: QGroundControl > General Settings (Settings View) > Video

3. 모든 것이 정상적으로 작동하게 되면, QGC 비디오 스위처 (QGC Fly View 왼쪽 하단 모서리)에 비디오 스트림이 표시됩니다. 아래 스크린 샷과 같이 비디오 스위처를 클릭하여 비디오를 전체 화면으로 전환 수 있습니다.
