dm368录制音视频时出错

大家好

用如下指令录制音视频文件，时长4h

gst-launch -e v4l2src always-copy=FALSE input-src=component ! 'video/x-raw-yuv,format=(fourcc)NV12,width=(int)1280,height=(int)1024,framerate=(fraction)25/1' ! TIVidenc1 codecName=h264enc engineName=codecServer contiguousInputFrame=TRUE bitRate=500000 rateControlPreset=3 ! queue ! mux. alsasrc  ! 'audio/x-raw-int,rate=8000' ! queue ! avimux name=mux  ! filesink location=filename.avi

发现在录制过程中   dm368会自己停止录制视频   

请问各位知道是什么原因吗

谢谢大家

    你好，

    请问有报什么错误么？是否有尝试打开一些debug选项获得更多的信息？
