Swresample.create in_cl ~in_sample_format:in_sf in_sr out_cl

create a Swresample.t with in_cl
channel layout, in_sf
sample format and in_sr
sample rate as input format and out_cl
channel layout, out_sf
sample format and out_sr
sample rate as output format. If a sample format parameter is not provided, the sample format defined by the associated AudioData module is used.
Raise Error "Swresample input/output sample format undefined" if a sample format parameter is not provided and the associated AudioData module does not define a sample format as is the case for Bytes and Frame.

do the same as Swresample.create

audio codec properties as output format.

Swresample.from_codec_to_codec in_ac out_ac
do the same as Swresample.create
with the in_ac
audio codec properties as input format and the out_ac
audio codec properties as output format.
Swresample.convert rsp iad
resample and convert the iad
input audio data to the output audio data according to the rsp
resampler context format.
Raise Error if the conversion failed.
