Slow track skipping

<< < (2/4) > >>

yapper:
Something does seem amiss. On my 2nd Gen iPod it is a bit slow when skipping forward a few tracks, but I'm talking maybe 1-2 seconds delay, not 30 seconds as you mentioned.

I tried skipping forward 10 tracks, and that slowed down to about 10 seconds delay, but again still not anything like your 30 seconds.

My tests were done with typical music tracks (approximately 4 minutes duration, 128k or 256k bit rates). Performance with larger files is likely to be worse.

When was the last time you used your iPod in a similar manner in the original firmware?

You might want to search this Forum, but, I seem to rember a problem relating track skipping and large album art.

I'm not sure what you mean. Apart from the arranging of the files I use it just like that every day while biking. No playlists, no nothing. If there's a track I dont like, I just fumble for the skip button and that's it. Works like a charm - but I didnt like that I cannot just use that ipod like a normal drive (when it comes to putting music on it), so last thursday I gave rockbox a spin.

A what in a what now? Unless that album art is somehow embedded in the mp3s I shouldnt have any. Why would I use diskspace on pictures, that thing is for music ;D (album art IS pictures, right?)

edit: I just tried it with only 6 files in the music folder, and it worked perfectly. With 1600, as it stands right now, its slow as molasses. Oh buffer, why wont you behave? It makes the whole thing pretty much un-usable.

Lear:
As far as I know, the FAT file system just isn't very efficient when dealing with folders with many files in it. However, if you enable the dircache in Rockbox, that isn't a problem any more (provided you let it finish scanning before doing anything; it shouldn't take many seconds anyway). If it was enabled, then the problem is something else...

But if you only had 6 files in the folder, then maybe all of them fit in the buffer, so skipping would indeed be fast then.
