private void video_start_Click(object sender, EventArgs e)

//CaptureCamera2();
CaptureCamera();
flog = 1;
}
不管怎麼改都是兩個picture box顯示同一支攝影機的畫面
已嘗試過許多方法 也用測試程式試過兩支攝影機都正常
但是使用opencv capture都只截取到同一隻的畫面
不知道是哪裡出了問題 想請教板上高手能否幫忙開釋一下

3F：推 KLoVeRs: 需要吳德清主任的幫助嗎? 09/08 15:49
4F：→ dsin: 你該不會只是把Item[0]改成Item[1]這樣做吧? 09/15 08:25
