[BUG]: the lengths of the features after FACodecEncoderV2 is not match

bug of FACodecEncoderV2

I have extracted prosody_feature and encoder_output from FACodecEncoderV2. It raise wrong when I use fa_decoder_v2 to extract vq codecs becaucse the lengths of prosody_feature(torch.Size([1, 20, 281])) and encoder_output(torch.Size([1, 256, 282])) is not same.

my code

wav_b = librosa.load(wav_b, sr=16000)[0]
wav_b = torch.from_numpy(wav_b).float()
wav_b = wav_b.unsqueeze(0).unsqueeze(0)
enc_out_b = fa_encoder_v2(wav_b)
prosody_b = fa_encoder_v2.get_prosody_feature(wav_b)
vq_post_emb_b, vq_id_b, _, quantized, spk_embs_b = fa_decoder_v2(
enc_out_b, prosody_b, eval_vq=False, vq=True
)

Hi, you need padding your wav length to multiples of 200 (hopsize)
