Hello,
I've recently been trying to use GStreamer (of with which I've had little experience) for general playback of video files. I am using Playbin2 for the bulk of my media processing. I began noticed extremely high CPU usage durring video playback in the main application I am working on. To try and narrow down the issue I created a more bare-bones application with just PlayBin2 and a video-sink that outputs to a JFrame. However, I stil experienced CPU usages upwards of 100% CPU when playing an mp4 file (Codecs: H.264, AAC, Resolution: 1280 × 720). Quicktime and VLC handle the same file with ~10-30% and ~55-60% CPU usage, respectively.
I am using the Java wrapper for GStreamer (
http://code.google.com/p/gstreamer-java/) and my setup consists of Playbin2/Pipeline it creates and a VideoComponent as the video-sink (VideoComponent is a Canvas component for drawing within Java and seems to use a autovideosink as its interface to GStreamer).
Any suggestions on how to perform performance with Playbin2 would be greatly appreciated. I'd be happy to provide anymore information if needed.
Thanks,
Sam
