FPS via GStreamer

[forflafor]

Hello everyone.
Is it possible to show the number of FPS on the OpenGL window when streaming on rtp?
The command I run on the host PC is the following:

gst-launch-1.0 -v udpsrc port=5005 caps = “application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96” ! rtph264depay ! decodebin ! videoconvert ! autovideosink

Thanks!

Hi,
You can run with fpsdisplaysink like:

... ! videoconvert ! fpsdisplaysink text-overlay=0 video-sink=autovideosink -v

Thanks for the reply.
I have already tried to use the command with “fpsdisplaysink” but I get the following error:
WARNING: erroneous pipeline: no element “fpsdisplaysink”

How I can solve?
Thanks.

Hi,
It is in plugins-bad package.
fpsdisplaysink: GStreamer Bad Plugins 1.0 Plugins Reference Manual

By default it is installed. A bit strange it disappears. You may try to re-install it through apt install.

I managed to install the missing plugin, but now the error is this:

WARNING: erroneous pipeline: could not link autovideosink0 to fpsdisplaysink0

By removing autovideosinkand adding fpsdisplaysink I can see the following information in the window: rendered, dropped, current and average.

Unfortunately I still can’t see any information on the current fps.

Hi,

/GstPipeline:pipeline0/GstFPSDisplaySink:fpsdisplaysink0: last-message = rendere
d: 127, dropped: 0, current: 30.00, average: 30.45

Do you see this print? it shows current fps and average fps.

What fps does the current and average information refer to?
From what I understand there are 3 types of fps: input, output and network.
Thanks.

Hi,
current shows fps of current 500ms. average shows fps from beginning.
