FS#1705 - files recorded w/ RB play back into negative time

I’m finding that files I’ve recorded on Rockbox play back
normally but are anomalous in the playback times shown.

For example, I have a file for which the total playback
time shown by Rockbox is 46:15. But when played the
actual time (as shown by “time elapsed”) is 47:28, and
“time remaining” runs negative to a total of -1:13. (That
is, after a “time remaining” of zero, each second of
playback adds a second of “negative time.”) The
“progress bar” reaches its end when “time remaining”
shows zero, and sits there till the track actually ends.

Though I haven’t checked all the files I’ve recorded on
Rockbox, I’ve seen this effect with many (perhaps all).

This doesn’t happen with files I’ve collected
elsewhere–that is, non-Rockbox, non-Archos files.

When played with WinAmp 3.0, the common MP3 player
for the PC, the effect is similar–but more pronounced.
The same file mentioned above plays to a time shown by
WinAmp as 51:54. (With the display set to “time
remaining,” it ends at +5:38.)

WinAmp shows the information for this file as follows:

Size: 25655056 byes
Header found at 4096 bytes
Length: 2787 seconds
73kbit (VBR), 106733 frames
22050 Hz Joint Stereo
CRCs: Yes

I’ve seen the same effect with files recorded with a
frequency of 44.1kHz as well. And I’ve seen it on files
recorded with two different Archos recorders.

On my non-Rockbox, non-Archos files, WinAmp displays
times normally.

Archos model: JBR20101
Archos version: 1.28
Rockbox version: CVS-030923 (flashed)

My files are recorded with a quality of 5, “independent
frames” no.

Ok, then I'm closing this report.

Did you try “Update VBR file”?

VBRfix solves the problem. The updated Rockbox manual now
makes it clear that this is what VBRfix is for. Thank you.
