Seeking in mp3 CBR file is very accurate and works fine. Now when lame has
default option to VBR level 4 and there is some problems in seeking.
This bug can be reproduced with ffprobe:
{{{
./ffprobe -show_frames -read_intervals
42.004898%+1,41.090612%42.031020,40.045714%41.116735 test-VBR4.mp3
}}}
Seek times are chosen from normal 'ffprobe -show_frames' without seeking.
So playing from begining is working ok. If everything goes fine those PTS
should be equal when seeking and when playing from start but now they are
not.
