About how to generate .ogg/opus file when i have data(binary file) by opus_encode(...) function C language API

[LifeMM]

I'm confused
ogg_opus_writer = pyogg.OggOpusWriter(
output_filename,
opus_buffered_encoder
)

why generate ogg file process ，add opus_buffered_encoder ,should become a little more independent. should have a function for generate ogg file(for already opus_encode data).
