使用i.MX6Q播放视频时，出现GPU报错，之后播放不能停止，像进去while循环！

录制视频脚本如下：

gst-launch-1.0 \
      v4l2src device=/dev/video9 !\
   image/jpeg,width=1280,height=720,framerate=30/1 ! \
      jpegdec ! \
      queue ! \
      videoconvert ! \
v4l2video0h264enc ! \
      h264parse ! \
queue ! \
mux.video_0 \
alsasrc !\
queue ! \
audioconvert ! \
audio/x-raw,rate=44100,bitrate=2048 !\
queue ! \
mux.audio_0 \
      matroskamux name=mux ! \
      filesink -elocation=test.avi

播放脚本如下：

gst-launch-1.0 filesrc location=test.avi ! \
      matroskademux name=mux mux.  ! \
            h264parse ! \
      v4l2video1videodec ! \
            videoconvert ! \
            video/x-raw,format=YUY2 !\
            videoscale ! \
            video/x-raw,width=640,height=480! \
      videoconvert ! \
      fbdevsink

播放之后出现问题（crash log）：
