I have followed Arnaut's instructions (thanks a lot) and that seems to be the problem, but it has not been completely fixed.     Using a webcam in my PC, and executing this pipeline the resulting AVI file is 'high-speed' (I record 15 "real life" seconds that are displayed in a video of 10 seconds lentgh): gst-launch-0.10 v4l2src num-buffers=200 ! 'video/x-raw-yuv,format=(fourcc)I420,width=640,height=480,framerate=(fraction)25/1' ! x264enc ! queue ! avimux ! filesink location=webcamtest.avi but just adding videorate before the encoder element (x264enc), it is displayed properly. Fine.     But in the board where I need to record the AVI file, when I add the videorate element, the pipeline hangs up (never finishes although it has the num-buffers property)!! gst-launch-0.10 mfw_v4lsrc capture-width=640 capture-height=480 num-buffers=200 ! video/x-raw-yuv,format=\(fourcc\)I420,width=640,height=480,framerate=\(fraction\)25/1 ! videorate ! mfw_vpuencoder width=640 height=480 codec-type=std_avc qp=25 iinterval=25 ! h264parse ! queue ! avimux ! filesink location=board.avi     Why??? How videorate works???     Thanks a lot.     All the best.     LD. </body> </html>
