I found a bug Ipod 240 video

<< < (2/3) > >>

Buschel:
The problem with the peakmeter is that it will update the LCD screen lots of times each second. This consumes the CPU (and always did). Other fancy WPS-screens show lots of bitmaps but do not update the screen that often.

Yeah I just looked at the link you sent me it talks about it refreshing 25 times per second. Feels like 10 FPS would work fine too - if thats possible to code in to a future build.

  Close to 2 years ago I discovered they now have 950mah batteries for ipods 5.5 videos. So I bought it thinking it was a Chinese gimmick where they just put a sticker on the 850 battery that says 950 but i was surprised to find out its legit. So i never really had any complaints about the battery life.

In any case you opened my eyes to an interesting fact and I am interested in seeing how much better the ipod will work in none 25FPS mode. I wish this was better documented somewhere for the semi-technical people like me. This and knowing about the "force USB charging " meaning 500ma usb charging would have made my ipod rockbox experience a lot better a lot sooner.

 But in any case i am very grateful to all people involved in rockbox and the contribution that they have made to the mp3 world.

Buschel:
As a first step I added some recommendations to the manual.

rbhawaii:
thanks  :D
Post Merge: December 18, 2011, 08:27:26 AMI removed the peak meter line from my WPS and the EQ works fine with no more stuttering.

It is so disappointing to have to give up the peak meter. 

Do you think trying to tweak the peak meter (in the settings) might help reduce the cpu cycles ? or is it that if its on then its sucking the same amount of extra cpy no matter how its set or what its doing.... do you know?

Buschel:
If you can compile rockbox you might just check the latest patch in http://www.rockbox.org/tracker/task/10686. In case you cannot build rockbox I have uploaded a custom build that includes this patch -> http://www.sendspace.com/file/60hnou

The patch reduces the update to 10 fps and should significantly reduce the CPU load caused by the peak meter.
