I was trying to exercise the winemp3 builtin codec using a Visual Basic control that essentially implements the Windows Media Player look (MSDXM.OCX). After specifying native quartz.dll for this app, I tested a few AVIs with mp3-encoded soundtracks. What I can notice is that the sound has very annoying jitters, and in addition, it crashes on a seek. Some people have noticed the jitters too (http://bugs.winehq.org/show_bug.cgi?id=3853). However, rather than trying to fix the wine fork of mpeglib, I was toying with the idea of reimplementing the codec as a libmad (GPL) wrapper. Are there any issues I should take into account before trying this?
