NUM_EXECUTORS="1"
SCREEN_RES="1440x1080x16"

xvfb_vncstart() {
  # dropping the vnc password into a text file for the vnc recording tool
  local PASSWORD_FILE=/tmp/vnc-password.txt
  if [ -f $PASSWORD_FILE ]; then
    rm $PASSWORD_FILE
  fi
  echo "$VNC_PASSWORD" > $PASSWORD_FILE
  export VNC_PASSWORD

  echo "Starting $NUM_EXECUTORS X servers..."
  export NUM_EXECUTORS
  for i in $(seq 1 $NUM_EXECUTORS); do
    echo "Launching X server $i..."
    # Start the X frame buffer implementation
    sudo -i -u ubuntu Xvfb :$i +extension GLX -screen 0 $SCREEN_RES -ac &> xvfb-$i.log &

    # Sleep a little to give programs a chance to start
    sleep 2

    # Start the fluxbox window manager.
    # We need a light window manager that allows maximizing windows
    sudo -i -u ubuntu DISPLAY=:$i fluxbox &> fluxbox-$i.log &

    # Sleep a little to give programs a chance to start
    sleep 2

    # Share the xsession over VNC
    sudo -i -u ubuntu x11vnc -forever -display :$i -N -passwdfile /tmp/vnc-password.txt &> vnc-$i.log &

    # Sleep a little to give programs a chance to start
    sleep 2
  done
}


But video recording doesn't work even when I try to run startx.

I have googled up and I was not able to find a concrete answer to why video was not working.. Any help or hints would help me a world of good.. Thanks in Advance for your reply!!!!!!

Answer 1

现在问题解决了。录制是在java进程中完成的。
pb = new ProcessBuilder（screenRecorderProcessLocation， “-一个”， “-s”，System.getenv（“SCREEN_RES”）， “-f”，“x11grab”， “-i”，“localhost：”+显示， “-vcodec”，“libx264”， “-r”，“24”， screenVideoFile.getAbsolutePath（））;

在环境变量中找不到SCREEN_RES值导致avconv停止录制..使用分辨率录制视频录制后的硬编码...检查的最佳方法是手动运行录制片段进行检查如果它的工作与否..然后实施..我20天后很幸运，不知道出了什么问题！大家欢呼！快乐学习!!!

视频录制无法在ubuntu14.04上运行
