Re: fpsdisplaysink usage

Hi,

Thanks for the response. I did send that mail to the gst-devel mailing list - but did not get any reply. I am copying this mail to gstreamer-devel as well.

What I need is the rendering fps. It would also be good if I get the max fps of the decoder as well.

My problem with the gst-plugins-bad v0.10.18 is that it gets out of the configure step complaining that it needs gst-launch version greater than 0.10.27. This doesn't happen when I use bad plugins 10.17.

Can I just comment that out in configure and proceed? Would fpsdisplaysink still work?

Thanks,

-Raghavendra

Still you should send those mails to e.g. the gstreamer-devel mailing list or ask on irc.

Yes.

Nothing there checks for the version of gst-launch. What is the error that you are seeing?

What do you want to meassure? The rendering fps? The max achievable fps of a decoder?

regarding max fps, you can use the fakesink sync=false approach I
suggested, given you know the number-of-frames in the video (should be
long enought to shadow pipeline startup time).

I am quite sure that configure does *not* check the version of
get-launch. Please show the error message that you get here.

Re: fpsdisplaysink usage

The error I get when I use ./configure for gst-bad-plugins 10.18 is "Requested gstreamer-0.10 >= 0.10.27" but version of Gstreamer is 10.25".

I will try moving to 10.27 or use other approaches to measure fps.

Regards,

-Raghavendra

Re: fpsdisplaysink usage

Hi Raghu,
there was a post a long time back on this. Search for '[gst-devel] how
to determine fps of a camera pipeline'

Excerpt below:
"Indeed, advised/requested fps might not always be the real one. For
measuring it, i use a trick: i place a videorate with arbitrary caps
after the source, and measure the dropped/duplicated frames to
determine the real framerate. You can see and exemple at [1].
[1] http://code.google.com/p/gst-plugins-elphel/source/browse/trunk/tests/test_elphel_perf.py"

This might do for the time being?
Cheers
-Pierre
