Hello,
looking at the wider availability of e.g. HD content, the market trend to less power hungry hardware and the many questions on our forum for hardware/codec/performance info, I thought is was time to start a performance thread.
Goal of this thread is to capture performance and experience of the CPU / GPU combination. The results would be three-fold:
1. giving advise on hardware selection;
2. better tweaking of our already installed / purchased hardware in combination with codes and last but not least:
3. ah well, just a show off of our (HTPC's) muscles
When we have enough results they could be collected and put in the wiki.
To get this of the ground I need some initial help in setting up a test script that captures performance in an easy way. Any thoughts / hints are welcome. This is what I have come up with initially.
Used Tools:
* Graphedit (to produce used codecs per test movie) [google for download]
* Procexp (sysinternals) (to capture CPU load during playback)
Test files:
Analog recording: mpeg2 / ts file: to be produced
SD file: The Melancholy of Haruhi Suzumiya ED theme SD video [Watching h.264 videos using DirectX Video Acceleration (DXVA). My collection of short anime reviews test file 1]
HD 720P file: Elfen Lied ED theme 720p [Watching h.264 videos using DirectX Video Acceleration (DXVA). My collection of short anime reviews test file 2]
HD 1080P file: Utawarerumono OP theme 1080p [Watching h.264 videos using DirectX Video Acceleration (DXVA). My collection of short anime reviews test file 3]
Testscript:
1. start graphedit
2. start procexp
3. start MP
4. goto windowed mode (MediaPortal)
5. switch to procexp and select MediaPortal.exe → properties / performance graph
6. switch back to MP and start test file 1
7. switch to graphedit and display running remote graph
8. switch to procexp and register lowest / highest CPU load during playback of the file
9. goto 6
Performance results: (in italics my specs / results)
Windows Version: Windows XP Professional Service Pack 3
CPU brand / type: AMD Geode NX1750
Memory: 1024 MB
Video card brand / type / memory: Nvidia GT8500 256 MB
Video card connection: onboard / agp (speed) / pcie / pci PCI
Renderer: VMR9 / EVR VMR9
MPEG-2 Video Decoder: MPC-MPEG2Video Decoder (Gabest)
H.264 Video Decoder: MPC Video decoder
Audio Decoder: MPC – MPA Decoder filter
Test file HD 720P
remote graph video: MPC - Video Decoder → Video Mixing Renderer 9
remote graph audio:MPC – MPA Decoder filter → Default Direct Sound Device
CPU low / high / average: 7% - 19% -12%
Test file HD 1080P
remote graph video: MPC - Video Decoder → Video Mixing Renderer 9
remote graph audio:MPC – MPA Decoder filter → Default Direct Sound Device
CPU low / high / average: 15% - 24% -19%
Questions:
Is there a better tools to capture more precise the CPU load for an application?
Are the testfiles representative for load / performance testing?
Do we need to register / test other variables in our system?
Looking forward to your feedback!
regards,
Ruud.
