Frame rate drops to 0.8 fps on increasing load

[Thomas Scheuermann]

Hi Nicolas,

the filters mentioned are caps-filters to get the right format I need.
So there are only standard gstreamer elements in this pipeline, no own written.

I will try to see what I can do with max-lateness.
And I have to read about the 'qos' property because I have no idea about this.
Do you have any links here for the 'qos' topic?

Regards,

Thomas

If I set sync=false, the framerate behaves like expected and goes
down
when I increase the load.
But I need to use sync=true.
What can I do that the pipeline with sync=true behaves the same way?

I use GStreamer 1.4.5



I'm guessing a bit, but I believe you need to set max-lateness property
to something that make sense (usually around the duration of a frame)
and enable "qos" property. You also need to make sure QoS is properly
implemented in your filters. This way, you stream performance should
degrade when the load (processing latency) increase.
