No; my suggestion is to use your own buffer which is big enough for your
decoder, and use this buffer to fill ALSA's buffer, whenever possible.

If one call to your decoder function needs so much time that ALSA's
buffer can become emptied, you need another thread to re-fill the ALSA
buffer in parallel with the decoding.
