<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Hi there;<DIV><BR class="khtml-block-placeholder"></DIV><DIV>I use mplayer to extract audio from MOV files and typically it works wonderfully! However, ones with AAC don't seem to extract properly -- I get a blank WAV. :-( The audio is played just fine when I view the MOV in mplayer. This problem seems platform independent -- I get the same results on Linux and MacOS X. My command line looks like this:</DIV><DIV><I> [localhost]% mplayer my_file.mov -really-quiet -channels 1 -ao pcm:waveheader:file= my_file.wav -vo null -vc dummy</I></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>It seems to work just fine for everything else (RM, WMV, MP3, MOV with other audio codecs, etc). </DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Here's my version info:</DIV><DIV><I> [localhost]% mplayer -ao help</I></DIV><DIV><I>MPlayer 1.0pre7-3.3.3 (C) 2000-2005 MPlayer Team</I></DIV><DIV><I>CPU: Intel Pentium 4/Xeon/Celeron Northwood (Family: 8, Stepping: 3)</I></DIV><DIV><I>Detected cache-line size is 64 bytes</I></DIV><DIV><I>CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1</I></DIV><DIV><I>Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2</I></DIV><DIV><I><BR class="khtml-block-placeholder"></I></DIV><DIV><I>Available audio output drivers:</I></DIV><DIV><I> mpegpes Mpeg-PES audio output</I></DIV><DIV><I> oss OSS/ioctl audio output</I></DIV><DIV><I> alsa ALSA-0.9.x-1.x audio output</I></DIV><DIV><I> arts aRts audio output</I></DIV><DIV><I> esd EsounD audio output</I></DIV><DIV><I> sdl SDLlib audio output</I></DIV><DIV><I> null Null audio output</I></DIV><DIV><I> pcm RAW PCM/WAVE file writer audio output</I></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Any fixes for this?</DIV></BODY></HTML>
