Problem playing LONG file on 5gen IPod

[bpmcgee]

Hi,

My 60GB iPod seems, in general, to work really well with RockBox.  Congrats (and thanks) to everyone for their hard work.

The problem I have is when playing long .mp3 files (about 10 minutes).  It will begin with some short clicks or stutters in the playback, and increase to longer stutters which sound like a record slipping it's groove.

My WPS doesn't use anything fancy like sound meters, and I have the EQ turned off.

Is this a known problem, or would you like me to post more information?

I haven't noticed this with my 5g 60GB iPod.

Some clarifications just in case:

- which generation iPod is it?
- what bitrate are the mp3s and VBR/CBR, etc.
- does the problem happen faster if you turn on EQs?

I don't have an answer, but this info may help others to diagnose what you are experiencing.

- 5gen (I thought I'd mentioned this, sorry).
- 256kbps fixed rate.
- I don't know, I've never turned it on.  Seems like if I DID turn it on, I wouldn't be able to tell the difference between this problem and the problem of skipping when the EQ was on.

A couple of other questions:

Does it happen at the same time for each such file?
What build are you using?
Is this a recent problem or has it persisted across multiple builds?

Sorry, I don't have any useful suggestions other than trying another build to see if the problem goes away.  I used to have issues with some of my AACs pausing intermittently because the codec could not quite decode them real time but I haven't had this problem in quite a while.  The mp3 codec is supposed to be better than real time now so I don't think the same sort of problem is causing this.  Hopefully someone else with more insight will see this.

If it's any consolation I haven't had any problems playing 320kbps mp3s (although they are generally shorter than 10 minutes).  I do have a couple of long mp3s I have just encoded that I will test out and see if I can reproduce this behavior.

Chronon,

No, it doesn't happen at the same point in each file, but it DOES happen at roughly the same spot if the same file is played repeatedly.

CVS-060926

I've only used the one build.

Hmm.  Well, I have listened to some long Pink Floyd mp3s recently with no such stuttering (320kbps CBR).  The easiest thing to do is to just install a newer build and see if the problem persists.  

Good luck.  Sorry I can't explain what you are seeing.
