FS#8807 - r16791 introduces playback skipping in ipod 5.5G (80GB)

The changes introduced in r16791 have resulted in choppy playback on the iPod 80GB 5.5G.

This is at its worst when the player is first turned on, while the dircache is building - but also occurs every time the folder changes during playback.

Whilst the playback is suffering these glitches, the playback controls are also unresponsive, making it hard to pause / stop playback - although access to the menus seems unaffected.

I suppose I'll close this as not 100% complete.

Argh. Let’s try this nasty thing again.

This patch makes things much better for me… The unresponsiveness is gone and buffering is much faster :)

MikeS commented on 2008-03-28 17:21

something in that port is being very bad >:-[

I guess I’ll commit this awful thing but I will still find a way to investigate.

I am wondering, is there something wrong with the Ipod Video port?

every so often, a commit seems to break buffering on the device. Don’t get me wrong, I am not complaining, I am realy just wondering :)

I am wondering as well since my test with an H10 running large sector access suffers no I’ll effects - not quite as fast but no problems and supposedly disk reads aren’t any slower on 5g. Do these problems happen if the CPU frequency is forced to 80MHz? Do they occur if a single core build is forced (see config.h to do that)? There’s a huge list of possible checks but debugging remotely turns minutes into days :P.
