Bug ID: 772841
Summary: udpsrc: high CPU usage at high packet rate
Classification: Platform
Product: GStreamer
Version: 1.8.3
OS: Linux
Status: NEW
Severity: major
Priority: Normal
Component: gst-plugins-good
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: brain at jikos.cz
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
A simple pipeline:
gst-launch-1.0 udpsrc uri="udp://224.100.1.1:5004" ! fakesink
is causing 30% CPU usage on a Cortex A7 @528MHz at 1000 packets/second
Such a high CPU usage is unacceptable, especially if a C program doing the same
- reading from a socket and discarding the data - needs just 3-4% CPU
This use case is crucial for handling low latency audio.
