Hi guys,

I have a simple uncompressed WAV file, which i want to split. The problem is that i amost never get the precise exact amount of sound i want, as per example:

ffmpeg -i 17203588.wav  -ss 1 -t 1 17203588_cut.wav

should cut out exactly one second from the stream, but:

ffmpeg -i 17203588_cut.wav 

outputs: 
ffmpeg version N-31743-g324b8ad, Copyright (c) 2000-2011 the FFmpeg developers
  built on Aug  3 2011 15:13:54 with gcc 4.5.2
.....
Input #0, wav, from '/home/alexandru-david/Exporter/exportWAV/userclips/17203588_cut.wav':
  Duration: 00:00:00.99, bitrate: 1411 kb/s
    Stream #0.0: Audio: pcm_s16le, 44100 Hz, 2 channels, s16, 1411 kb/s
At least one output file must be specified


This is a pretty happy case though, sometimes i'm missing more millis from the output. And it's very important to get the precise length i need because i'm concatting those WAVs and sometimes i get little pauses at concat time in the final sound.

Any ideas, tips or tricks for me?

Thanks in advance,

Regards,
DAV
