    WTF is this fascination with 'cats' ?

    Sorry no cat here only a dumb dog.

    Doesn't -acodec pcm work ?

    btw lpcm is not, technically a codec since it is uncompressed.

  3. I wonder if ffmpeg can encode in a "declared" lpcm mode ^^

    pcm and lpcm are one and the same.

    So again and with clarification

    Does not "ffmpeg ........... -acodec pcm............." work ?

    Woof !!!!!!!!

    "Normally", or perhaps AFAIR , PCM means *little-endian* and LPCM means *big-endian*

    FWIW, ffmpeg -codecs returns the following:

     D.A..S pcm_bluray           PCM signed 16|20|24-bit big-endian for Blu-ray media
     D.A..S pcm_dvd              PCM signed 20|24-bit big-endian
     DEA..S pcm_f32be            PCM 32-bit floating point big-endian
     DEA..S pcm_f32le            PCM 32-bit floating point little-endian
     DEA..S pcm_f64be            PCM 64-bit floating point big-endian
     DEA..S pcm_f64le            PCM 64-bit floating point little-endian
     D.A..S pcm_lxf              PCM signed 20-bit little-endian planar
     DEA.L. pcm_mulaw            PCM mu-law / G.711 mu-law
     DEA..S pcm_s16be            PCM signed 16-bit big-endian
     DEA..S pcm_s16be_planar     PCM signed 16-bit big-endian planar
     DEA..S pcm_s16le            PCM signed 16-bit little-endian
     DEA..S pcm_s16le_planar     PCM signed 16-bit little-endian planar
     DEA..S pcm_s24be            PCM signed 24-bit big-endian
     DEA..S pcm_s24daud          PCM D-Cinema audio signed 24-bit
     DEA..S pcm_s24le            PCM signed 24-bit little-endian
     DEA..S pcm_s24le_planar     PCM signed 24-bit little-endian planar
     DEA..S pcm_s32be            PCM signed 32-bit big-endian
     DEA..S pcm_s32le            PCM signed 32-bit little-endian
     DEA..S pcm_s32le_planar     PCM signed 32-bit little-endian planar
     DEA..S pcm_s8               PCM signed 8-bit
     DEA..S pcm_s8_planar        PCM signed 8-bit planar
     DEA..S pcm_u16be            PCM unsigned 16-bit big-endian

     DEA..S pcm_u24be            PCM unsigned 24-bit big-endian
     DEA..S pcm_u24le            PCM unsigned 24-bit little-endian
     DEA..S pcm_u32be            PCM unsigned 32-bit big-endian
     DEA..S pcm_u32le            PCM unsigned 32-bit little-endian

    You don't just use "-acodec pcm", you have to use "-acodec pcm_s16be" or "-acodec pcm_s16le", etc. PCM for pcm, S for signed U for unsigned F for Floatingpoint, 16 for 16bit (8, 20, 24, 32 etc.), be for BigEndian and le for LittleEndian (depending on which works for your application). Planar, mu-law/a-law and the bd & dvd presets are the only unusual ones.
