Developers told me to pass -e to gst-launch to stop with CTRL+C sending the EOS ... but when I do gst-lauch-0.10 -e, it says "Error initializing: Unknown option -e". How do you do that? 2.- Using this pipeline I save an AVI file: gst-launch-0.10 mfw_v4lsrc capture-width=640 capture-height=480 num-buffers=250 ! video/x-raw-yuv,framerate=25/1,width=640,height=480,format=\(fourcc\)I420 ! mfw_vpuencoder width=640 height=480 codec-type=std_avc qp=25 iinterval=25 ! h264parse ! queue ! avimux ! filesink location=test.avi I get 250 buffers, and I force to 25 fps, so the file (I have checked it) has a lenght of 10 seconds. But the "real time" that I record (recording a chronometer) is more than 25 seconds. How can I check the real frame rate that the source element or the encoder are giving??? Is there some way to check that??? (removing the cap between the source and the encoder, it happens exactly the same). It could be some problem with the gstreamer clock???     THANK YOU VERY MUCH.     All the best.     LD. </body> </html>
