      <br>
      You could use fpsdisplaysink, that'll print out the number of
      frames per second. <br>
      <br>
      On the other hand, v4l2src is a live source. If you are not
      planning to synchronize with audio or something similar I don't
      see a problem setting "sync=false" on your sink. You could also
      try increasing "max-lateness", but I'd turn off sync.<br>

          Hello, I'm trying to find a way to measure the number of
          frames provided by<br>
          v4l2src. When I'm testing the pipeline, I use videotestsrc and
          I think that<br>
          videotestsrc is providing a higher amount of frames than
          v4l2src. I know<br>
          that videotestsrc is different from v4l2src because v4l2src is
          actually<br>
          connecting to the hardware. I'm just looking for a way to
          measure the amount<br>
          of frames v4l2src is outputting.<br>
          <br>
          Here is my pipeline:<br>
          v4l2src ! videoconvert ! eglglessink name=videosink<br>
          <br>
          I'm using gstreamer 1.2. I can't upgrade to 1.4 due to my
          current<br>
          requirements.<br>
          Also, when I switch back to v4l2src, eglglessink states in the
          logs that<br>
          frames are being dropped. When I add the property sync=false,
          that stops.<br>
          <br>
          Any suggestions are appreciated.<br>
          <br>
