[Libav-user] Trying to play audio files, but click sound at the start of mp3 files with a xing header.

[ptrdactyl]

Im trying to play audio files using libav, libswresample, and libao.

It mostly works, except for some mp3 files with a xing header there is a 
click sound at the very start. It doesnt happen for all such files 
though, if i strip a file's xing and id3v2 metadata and then add a xing 
header, theres no more click sound (i dont know why, the only difference 
is theres less metadata and the start_time/start_pts are less). I think 
it should be reproducable by converting something like a song with 
typical amount (for a song) of metadata into mp3.

my code is here: https://0x0.st/H_m4.c

sorry if its a mess, its very difficult to find useful documentation on 
how to do this stuff.
