I tested the fix, it works well now. I tried to review the code logic
but found it hard to figure out this line on my own due to the
unfamiliarity with this module currently:

stream->buffers[stream->queue_size + stream->oldest_buffer_index] =

                InvalidBuffer;

Could you please elaborate on it a little bit more? Thanks.

Best,
