Hello,
I develop a benchmark and performance test application based on gstreamer. Is there a plugin or a way to display/output real fps from the playback. Any other meaningful metric that can be used for evaluating performance is useful also. Thanks.

You could use identity (which you can insert anywhere in your pipeline), and connect the signals "handoff": * wo a callback incrementing a counter you reset every second, which will give you second-scale fps average measurement * to a callback measuring difference beween consecutive timestamps, which will give you instantaneous fps measure (fps will be 1/difference) If you are only interested in pure display/playback performance measurement, you could take a look at QoS events' timestamps emitted from sinks (see gstreamer/docs/design/part-qos.txt). For memory/cpu usage, you could use standard system calls or /proc parsings. I hope this helps. Maybe there are better ways to do this... Can you elaborate on the kind of performance you would like to measure ?

Thanks, Florent.
FPS is meaningful for me to see when cpu is not able keep it at maximum, I also need a way to measure how much performance I gain with hardware codecs. I used handoff event as you suggested and I had to split the stream into two with tee and feed one to fakesink. So it works :) Then I need to measure what do I get with XV, since colorspace conversions and scaling can be done with it. From here perhaps I can measure cpu usage, but to use FPS wouldn't be fair, because I can't go with gstreamer beyond xvimagesink. I will study what I can do with QoS events. -- Aarto On Thu, Apr 16, 2009 at 4:27 AM, Florent <[hidden email]> wrote:

Atleast I wanted to make the overlay optional.
