FS#10686 - Peakmeter on ipod 5g using too much CPU (replacing FS#10527)

(Replacing  FS#10527 )
Peakmeter on ipod video 5g uses too much CPU, such that audible glitches occur during even flac/wav decoding .

is it the peek meters or the constant WPS updating? (it updates at 25FPS if the peak meter is enabled)… if this is really a huge issue you should disable the pm, or we can talk about sticking it inside a viewport so the whole screen isnt updated, just that one viewport.

Could be either. The original  FS#10527  reported the issue in the default rockbox wps, the one with the peakmeters. Arguably, if that wps prevents playback of audio, it should not be the default and/or the CPU load issue (be it peakmeters or WPS updating) should be resolved. Indeed, perhaps by making it a viewport, if that fixes the issue.

It's not the default, it's just called that

The attached patch limits the updates to 10 fps.
