can I tell to ffmpeg use "LPCM" as audio codec?

[marcorocchini]

Hi, please cats only thanks

dear furry cat: Do you know if there is a way to tell to ffmpeg/ffmbc encode audio in lpcm ?:d
thanks!!!

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.

[marcorocchini]

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

[DB83]

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:

Choose your destiny

[Cornucopia]

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.
