Incompletely decoded data

[Jekahome]

Good afternoon.
I'm assuming you're cutting off samples too early here. After all, info.frame_bytes is read from the buffer input_buf about 365-366 bytes.
Thus, you cut off the sound without reading input_buf.len()-info.frame_bytes => BUFFER_SIZE=1024 - 365 = 659 bytes i.e. a couple more decoded samples you cut off
