1712,Audio precision in lossless and long time to encode.,Danixu,,"Summary of the bug:
Hi, first of all, i'm sorry for my english.
I've tried the last ffmpeg build and i get a problem with Audio precision in lossless audio file, the audio is delayed about 2 seconds.
The audio is passed to another program throught a pipe, but i know that the other program isn't the problem, because with a very old ffmpeg version (SVN 16573, Jan 13 2009) works fine, and i've tried with wav output without pipe and get the same problem.

If you want, here's a test wav files: http://www.mediafire.com/?1ewceliyjhspedk

The command line that i've used is :
ffmpeg_old -i ""input.ape"" -ss 00:59:18.71 -t 00:00:15.55 out_oldffmpeg.wav
ffmpeg -i ""input.ape"" -ss 00:59:18.71 -t 00:00:15.55 out_newffmpeg.wav

How to reproduce:
{{{
% ffmpeg -i input -ss 00:45:25 -t 00:05:25 -ac 2 -f wav -

The output is a pipe to another program.

The other thing that i wan to answer is why the program take a long time to convert a portion of a file, for example:
ffmpeg -i input.ape -ss 00:45:15.42 -t 00:00:15.25 output.wav

the program stay a long time without do anything and then start to convert. I take about 2 minutes to convert 15s of audio.",defect,open,normal,FFmpeg,git-master,,,,,,1,1
