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>
<br>
