[Libav-user] List of FMT for available decoders

[Ingo Foerster]

Hello Carl Eugen Hoyos,

I'am  sorry, my question was a little bit unclear written. What I ment
is the Sample_fmt of the audioc codec, as sample: AV_SAMPLE_FMT_S16
There  are  many audio codecs available and it will be very helpful to
have a list of the decoders and sample-fmt to write own converters.

Regards,

Ingo
