Could iamf-tool support frame based encoding?

encoder_main_lib.cc
IamfEncoder iamf_encoder(user_metadata);
RETURN_IF_NOT_OK(GenerateObus(
user_metadata, input_wav_directory, output_iamf_directory, iamf_encoder,
ia_sequence_header_obu, codec_config_obus, audio_elements,
mix_presentation_obus, audio_frames, parameter_blocks, arbitrary_obus));

RETURN_IF_NOT_OK(WriteObus(user_metadata, output_iamf_directory,
ia_sequence_header_obu.value(), codec_config_obus,
audio_elements, mix_presentation_obus,
audio_frames, parameter_blocks, arbitrary_obus));

The encoding input is wav file, could it support frame based encoding(input PCM with fixed frame size, e.g. 960)?
regarding live cases, I think frame based encoding is necessary.

Yes, I agree that is needed. It is planned.

Do you have the estimated time to support it?
