Hi All,

I used the below command to record the video from a UVC CAM, it records. But the size is too large. How to add encoding to this??

gst-launch-0.10 v4l2src device=/dev/video0 ! video/x-raw-yuv,width=352,height=288 ! avimux ! filesink location=test0.avi


Below command i used for streaming a single CAM.. it works fine... How to so streaming and recording at same time... read in the abv link should add "tee".. can someone share any documents regarding this??


gst-launch v4l2src device=/dev/video0 ! video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! mfw_isink disp-width=450 disp-height=300  axis-left=50 axis-top=100


And for $gst-launch v4l2src num-buffers=-1 ! queue ! vpuenc codec=0 ! matroskamux ! filesink location=output.mkv sync=false
