I have some long form mp3s (1hr50mins or so) and I was trying to fast forward through them and about 30 minutes or so the time elapsed counter would go from, say "25:18" to "-3:-7" and I could no longer fast forward through the track.
Is this a software bug or perhaps a problem with my phone? (Nokia 6620, oggplay 1.6.1, music is stored on 512 mb mmc card)
A real nice feeature would be either bookmarking times or adding a "Go to time" function...
I suspect this to be a firmware bug. I tried to repeat it with my phone, and I could get up to 65:00 something. Then it jumped back to the start. If it would have jumped at around 30:00 like you told, I wouldn't have been so sure about a possible bug in OggPlay, but since the number differs soo much, there is probably something in the mp3 plugin.
Have you tried if the built-in player was doing the same?
A bit more specific, it seems to happen at almost exactly 35:47 in two different long tracks in oggplay. If I let it, it will keep playing, but if I try and fastforward after the timer has "reset", it will jump back to the beginning.
In the built in player I can't really even fastforward that far, it seems to freeze after tapping the fastforward button so much.
