Will converting backdrops to BMP improve performance? (1 Viewer)

[vl002001]

The BasicHome menu runs quite smoothly until it transitions to a new backdrop, after which it will lag at each change and then smooth out until the next transition.

Will converting all backdrops to uncompressed BMP's improve on this? or is there anything else I can do?

Thanks! Great work!

Backdrops should transist very smoothly if you have a well configured and powerfull enough system. What is your current hardware?

Converting to BMP

I have been wondering about this as well.

I have a fairly decent machine (AMD Phenom X3 with 4G mem) with no problems viewing any video.

There isn't much of a delay switching between the fanart, however, the machine works harder when showing the basic homescreen with the fanart than it does showing any other video.

Will converting all of those jpg images to bmp cut down on the apparent workload?

AMD Athlon 64 X2 5200+ Brisbane Dual Core Processor 2.7Ghz
GIGABYTE GA-MA78GM-S2H AMD 780G AMD Phenom Socket AM2+ 5200 MHz PC2-8500
4gb ram
Vista x86

System seems like it would be powerful enough to handle it. but like i wrote earlier, when the transition happens, it gets choppy when you scroll. then it smooths out once you get through all of them, and gets choppy again at the next transition (if that makes any sense).

are there some configuration changes i can make to make it smoother?

I'm not familiar with any settings that should impact this save there may be some backdrop transistion settings in StreamedMP (this is a guess from my side).
Your hardware should certanly be more than able to run this smoothly. Weird problem, loading images really isnt a job that processors over 1000mhz should have problems with Viewing png files with a image viewing program for instance poses no problems i assume?

I would think BMPs would be slower. BMPs tend to be larger than JPG files, so would take longer to load.

But...... Is less compressed, so less CPU time would be required.....

Save one of you backdrops as .bmp then double-click it in Explorer. You'll notice that it'll open faster than a jpeg. Just like any compressed files, they need to be "unpacked" to be viewed.

I know for a fact that having .bmp backdrops is recommended by for example XBMC, so I can't see any reason that MediaPortal should handle pictures differently than any other windows apps.

Emph

i didn't think there is any unpacking, like there is in a zip file.
the compression is used to make the file and is set, the stuff that is thrown away during compression can never be retrieved


although i'm not sure why BMP's would open any quicker, unless as a native windows file format windows handles them better

emphatic is right. bmp would load faster than jpg because it's uncompressed. rendering time is less.
