Description RonHatl 2009-11-26 11:21:42 UTC

Both in web ui and SB3 ui the bitrate and track length is wrongly displayed for 64 kbps bitrate files. The file plays fine, so the biggest problem is FWD/REW on remote, as file length is shorter than correct it is not possible to scan forward to e.g. position 2 minutes and 55 seconds, in e.g. the attached file:

Correct data: 64 kbps, length in minutes 03:49
SbS shown data: 131 kbps, length in minutes 01:51

PS. This was never a problem with the same type of files (same encoder, same bitrate/settings, etc.) on SC 7.3.x.

Fixed bug 15197, frame length calculation for MPEG-2 Layer 3 files was wrong, resulting in wrong bitrate/duration being calculated
