I've tried running an mp3 file through mp3parse like this in both 0.6 and 
0.7.x (cvs-head): 
 
gst-launch filesrc location=in.mp3 ! mp3parse ! filesink location=out.mp3 
 
(purpose was to clean mp3 from random rubbish and tags before processing 
it further). 
 
However, the output mp3parse produces contains noticable skips when 
played, so something is not working right. 
 
 
Source 1: 
(has clean mpeg audio frame sync at beginning): 
 
filesize   
4303306   mp3.in      (source, contains ID3v1 tag at the end) 
4302889   mp3.out-0.6 (sounds like source) 
4214403   mp3.out-0.7 (has at least 1 audible skip or error/second) 
 
 
Source 2: 
(first clean mpeg audio frame sync at byte 252): 
 
filesize 
3393919   mpeg.in        (source, has no ID3 tags) 
3393411   mpeg.out-0.6   (sounds like source) 
3320635   mpeg.out-0.7   (constant audible skips) 
 
 
So it looks like there has been a regression since 0.6.4 and 
0.7.x-cvs-HEAD.
