Information needed: how to measure video fps

Hi all,
I have a query on how to measure fps with gstreamer. The version of gst-launch with me is 10.25.

I came across gst-plugins-bad-0.10.18 (release notes say that this has fpsdisplaysink)- but that is not compatible with gst-launch -10.25 that I am forced to use.

I then tried gst-plugins-bad-0.10.17 - I got it built but it looks like it doesn't have fpsdisplaysink. I also couldn't find any documentation on a "videomeasure" plugin.

Can any of you help me get the fps using any method?

Thanks,
-Raghavendra

Hi,

I think the fastest way is to install a probe on the sink pad of the
videosink element you're using then count the buffers arriving e.g.
each 10 seconds (it depends on the granularity you want to measure the
fps).

Regards

I use this hack for gst-launch that adds a probe on any pad:
http://github.com/mrchapp/meta-texasinstruments/blob/for-23.i3.5-pre2/packages/gstreamer/gstreamer/gst-0.10.25-gst-launch-Add-pad-probe.patch

Then you can do:
gst-launch --padprobe videosink0:sink --timer \
videotestsrc ! fakesink name=videosink0

Greetings!
