Lack of Visualizations

Have to agree with all the above. Put something in place, write some tutorials, make it easy to understand. They will come...

I still use R4 the most amazing music visualizations ever....

Hi folks,

New here, but I've been poking on the ProjectM source code for awhile now, so I thought I'd share my work here as there does indeed seem to be interest.

I've mainly been working on the "beat detection", but also have some MilkDrop compat improvements.

The existing projectM sound analysis is based on some statistical energy methods, I've replaced this with an FFT based approach. The results are IMO a dramatic improvement in the standalone version of projectM. I've ported the patch to the XBMC version of ProjectM, however the results are very disappointing..

It seems XBMC does not provide frequent updates of the audio stream to visualizations, so while the viz is running @ 60fps, the audio data is only being refreshed in the area of 10fps. At least thats what I observe.. I've seen one or two mentions of this elsewhere, so I assume its not just on my system.

I'll be looking into fixing this audio refresh issue in XBMC if I can locate its cause and then I'll look at submitting a patch to XBMC. Does anyone have any insight on this?

Anyway, if there's interest I'll definitely arrange to share my code, as I am also interested in having a good viz solution for XBMC.

@kid_meier, also there's a newer ProjectM which supports more and newer presets, have you looked at this ?

Furthermore there's many Milkdrop presets which simply doesn't work correctly

And last, AE (our new audio system) will bring changes to the viz-api I believe so changes are coming

kid_meier,

Welcome to the forums. I'm glad to hear you're working on improving this area of xbmc. Xbmc only supports MilkDrop 1.04 presets, does these MilkDrop compatability improvements you briefly mentioned mean we will finally see 2.0.1 support?

Are you referring to projectM 2.0 with shader support? I am aware of it, and I've actually also shoe-horned this version into XBMC. My reference to my work MilkDrop compat is most in reference to the shader support.

I have no silver bullets, but I think my changes are a definite improvement. I'll take a peek at the new AE and see if that helps. I also saw a reference in the Fische thread that disabling pulseaudio may help...

Thanks,
/mike.

@kid_meier Good luck!

I'm curious. What is the best looking waveform/spectrogram type option available? There's a waveform viz, but it's just an unattractive single line.

Is there no way to have a waveform like this overlayed on the album arm?

I'll leave this deer:
