I need the internal video streaming address of herelink ground terminal instead of qgcapp. We have developed a new app, but we can’t get the video interface. Can someone tell me the interface?

void VideoStreamControl::_startVideoStreaming() {
    if (_linkInterface == NULL) {
        return;

    int len = mavlink_msg_to_send_buffer(buffer, &msg);

Michael_Oborne · 8 April 2022 08:06

ok here is code from another sample app

github.com

ArduPilot/MissionPlanner/blob/master/plugins/example4-herelink.cs#L171


}

private void but2_Click(object sender, EventArgs e)
{
    var mav = Host.comPort.MAVlist.FirstOrDefault(a =>
        a.compid == (byte)MAVLink.MAV_COMPONENT.MAV_COMP_ID_CAMERA);

    if (mav == null)
        return;

    const int MAV_CMD_VIDEO_STOP_STREAMING = 2503;

    mav.parent.doCommand(mav.sysid, mav.compid, (MAVLink.MAV_CMD)MAV_CMD_VIDEO_STOP_STREAMING, 0, 0, 0, 0, 0, 0, 0, true);

    mav.parent.doCommand(mav.sysid, mav.compid, MAVLink.MAV_CMD.VIDEO_START_STREAMING, 1, 0, 0, 0, 0, 0, 0, true);
}

private void but1_Click(object sender, EventArgs e)
{
    var mav = Host.comPort.MAVlist.FirstOrDefault(a =>
        a.compid == (byte)MAVLink.MAV_COMPONENT.MAV_COMP_ID_CAMERA);

please connect camera to hdmi1. hdmi1 must be valid

wangsu · 9 April 2022 07:05

We are now sending commands in the format you gave us, but we still can’t switch to the hdmi2 source. Here is our code and the information returned by debug.

Michael_Oborne · 9 April 2022 09:01

why is target_sysid 0, and target component

wangsu · 9 April 2022 12:12

MAV. SYSID and MAV. Compid should be?

wangsu · 12 April 2022 02:35

I tried and still couldn’t solve the problem. It’s just a problem

wangsu · 13 April 2022 05:50

I can’t switch the HDMI video source with MP. I asked the manufacturer’s after-sales service, and the after-sales service said that MP can’t switch either. I now refer to the MP code and can’t switch. Is there really no way? This matter has been put on hold for nearly half a month

wangsu · 14 April 2022 05:02

Can you help me solve this problem? I can’t switch videos
