1.0 > vlc > 0.10 > mplayer



Completely unscientific benchmark, just to get you salivating for GStreamer 1.0



X = time, Y = CPU%
gst 0.10 and 0.11 from git, vlc 1.1.12, vlc 2.0.1-0-gf432547, mplayer SVN-r33713-4.6.1
test file: video: H.264 - audio: MPEG-4 AAC

(benchmark created by Wim Taymans)

Whoa, why does VLC 2 perform so poorly, especially compared to VLC 1? Which codec(s) were tested here?

The problem with vlc2 is related to audio: go to settings>advanced>audio>SRC sampler> and choose another type of sample rate converter...I chose Zero Order Hold...you'll see a huge cpu usage decrease

Can you do that again with a bit of rolling average?

However, VLC is the only one in the sample that has a half decent GUI, and that's saying something given how poor it is. So really, all bets are off.

@Scott M. GStreamer is a platform library not a playback app so your point is mute.

@Anónimo: Changing the resampler chopped off the tops a little but overal CPU usage is far above old vlc. I also tried enabling VDPAU (through VAAPI), which was even slower (but cpu usage didn't change much in busy vs calm scenes).
