You need to tell ffmpeg via the input file parameters (before "-i" what type of file to expect. In your case, that should probably be "-f s16le": ./ffmpeg -f s16le -i ~/file.raw -acodec mlp -b:a 18m -r 29.97 -strict unofficial -sample_fmt s16 ~/final.mlp (Depending on what sort of file ~/file.raw actually is.) > Please help me out Hope this helps, Moritz _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
