[Libav-user] Question about g726 codec

[Nicanor Garcia]

Hello,

In ITU-T G.726 Recommendation, it is defined that the input to G.726 codec
should be u-law or A-law PCM audio, which in time is converted to uniform
PCM before the encoding.

Does the same apply if I want to use the g726 codec found in libav (that
is, using avconv), or can I use a normal .wav file directly as input?

On a related note: Where can I find more information about the use of
several audio codecs included in libav, such as the default parameters?

Thank you very much.
