As you might haven’t seen i’ve written an article which measures and compares different media features on Raspberry Pi running an OpenELEC distro. So this test is about the same thing but only comparing video playback over network share.
Continues the same as here.
– Raspberry Pi CPU and Memory usage playing 3D 1080p DTS video over network.
So this confirms what I emphasized on last performance test: Raspberry Pi handles just fine 3D 1080p DTS video over network share. That’s just awesome! Today i’ve seen a whole 3D 1080p DTS movie, paused it, fast forwarded it, etc, and it didn’t crash neither had a buffered scene!
– XBMC.bin process CPU and Memory usage playing 3D 1080p DTS video over network.
This proves us that most of the Raspberry Pi CPU and Memory usage comes from XBMC process. Even so, it isn’t much!
To conclude this small performance test let me show you a comparison between 720p, 1080p and 3D 1080p video playback over network share.
Note: X axis represents seconds of the test.
Through Figure 5 it’s possible to see that something uncommon happened when I played 1080p video: 100% CPU usage during 80 seconds. That didn’t happened with 3D 1080p video. Even so memory usage is within a normal average.
So the previous problem with 1080p playback was obviously caused by XBMC, but i still can’t get why. But 1080p and 3D 1080p video have a very similar average value.
Up until now I could do everything media related with RPi and OpenELEC, except MPEG-2 playback (for now). This test just shows RPi is able to decode any H.264/MPEG-4 AVC video without much effort!
I’ll try to compare all OpenELEC results with lastest Raspbmc version RC4.
