  Hello et merci. J'ai testé et je commancait à m'énerver quand j'ai relu la page de man. Et l'option "-aop" n'est valable que pour MPlayer (donc pas pour MEncoder).
  
  Ce que je recherche, c'est amplifier à l'encodage, mais merci quand même, je vais investiguer la dedans.

             -af <plugin1[=options],plugin2,...>
                    Activate a comma separated list of audio filters and their options.
                    Available filters are:
      
                       resample[=srate[:sloppy][:type]]
                            Changes the sample rate of the audio stream to an integer srate (Hz).  It only supports the 16 bit little endian format.
      
                       channels[=nch]
                            Change  the  number of channels to nch output channels.  If the number of output channels is bigger than the number of input channels empty
                            channels are inserted (except mixing from mono to stereo, then the mono channel is repeated in both of the output channels).  If the number
                            of output channels is smaller than the number of input channels the exceeding channels are truncated.
      
                       format[=bps,f]
                            Select  the  format  f  and bytes per sample bps used for output from the filter layer.  The option bps is an integer and denotes Bytes per
                            sample.  The format f is a string containing a concatenated mix of:
                            alaw, mulaw or imaadpcm
                            float or int
                            unsigned or signed
                            le or be (little or big endian)
      
                       volume[=v:sc]
                            Select the output volume level.  This filter is not reentrant and can therefore only be enabled once for every audio stream.
                               v: desired gain in dB for all channels in the stream.  The gain can be set from -200dB to +40dB (where -200dB mutes the sound completely
                               and +40dB equals a gain of 1000).
                               sc: enable soft clipping.
      
                       pan[=n:l01:l02:..l10:l11:l12:...ln0:ln1:ln2:...]
                            Mixes channels arbitrarily, see DOCS/HTML/en/devices.html#audio-dev for details.
                               n: number of output channels (1-6).
                               lij: how much of input channel j is mixed into output channel i.
      
                       sub[=fc:ch]
                            Add sub-woofer channel.
                               fc: Cutoff frequency for low-pass filter (20Hz to 300Hz) default is 60Hz.
                               ch: channel number for the sub-channel.
      
                       surround[=d]
                            Decoder for matrix encoded surround sound, works on many 2 channel files.
                               d: delay time in ms for the rear speakers (0ms to 1000ms) default is 15ms.
      
                       delay[=ch1:ch2:...]
                            Delays the sound output.  Specify the delay separately for each channel in milliseconds (floating point number between 0 and 1000).
      
                       export[=mmapped_file[:nsamples]]
                            Exports the incoming signal to other processes using memory mapping (mmap()).
                               mmapped_file: File to map data to (default: ~/.mplayer/mplayer-af_export).
                               nsamples: number of samples per channel (default: 512)

        Parfait, merci beaucoup !!!!
        
        Le son sature un peu si on augmente beaucoup, mais entre +5 et +10 db c'est très correct.
        
        Merci encore !!!!
