Python alternative to ctypes, can't figure how to convert a code

NNestarZ2/15/2023
Hello, I am trying to convert a Python ctypes code to Deno using FFI, but can't know why its not working
import ctypes

class WhisperFullParams(ctypes.Structure):
_fields_ = [
("strategy", ctypes.c_int),
#
("n_max_text_ctx", ctypes.c_int),
("n_threads", ctypes.c_int),
("offset_ms", ctypes.c_int),
("duration_ms", ctypes.c_int)

whisper.whisper_init_from_file.restype = ctypes.c_void_p
whisper.whisper_full_default_params.restype = WhisperFullParams
whisper.whisper_full_get_segment_text.restype = ctypes.c_char_p

# initialize whisper.cpp context
ctx = whisper.whisper_init_from_file(fname_model.encode("utf-8"))

# get default whisper parameters and adjust as needed
params = whisper.whisper_full_default_params()
params.print_realtime = True
params.print_progress = False

# load WAV file
samplerate, data = wavfile.read(fname_wav)

# convert to 32-bit float
data = data.astype("float32") / 32768.0

# run the inference
result = whisper.whisper_full(
ctypes.c_void_p(ctx),
params,
data.ctypes.data_as(ctypes.POINTER(ctypes.c_float)),
len(data),
)
import ctypes

class WhisperFullParams(ctypes.Structure):
_fields_ = [
("strategy", ctypes.c_int),
#
("n_max_text_ctx", ctypes.c_int),
("n_threads", ctypes.c_int),
("offset_ms", ctypes.c_int),
("duration_ms", ctypes.c_int)

whisper.whisper_init_from_file.restype = ctypes.c_void_p
whisper.whisper_full_default_params.restype = WhisperFullParams
whisper.whisper_full_get_segment_text.restype = ctypes.c_char_p

# initialize whisper.cpp context
ctx = whisper.whisper_init_from_file(fname_model.encode("utf-8"))

# get default whisper parameters and adjust as needed
params = whisper.whisper_full_default_params()
params.print_realtime = True
params.print_progress = False

# load WAV file
samplerate, data = wavfile.read(fname_wav)

# convert to 32-bit float
data = data.astype("float32") / 32768.0

# run the inference
result = whisper.whisper_full(
ctypes.c_void_p(ctx),
params,
data.ctypes.data_as(ctypes.POINTER(ctypes.c_float)),
len(data),
)
I am looking for a bit of help, any would be gladly welcomed ! For now the code just hang when calling whisper.whisper_full_default_params

Hmm. It's hard to say what is going on as I don't know whisper (library?) nor the ctypes library you're using here.
