FFmpeg resamples narrowband SILK (TOC configurations 0-3) from 8 kHz and
holds back 24 samples of the first narrowband packet after the decoder
starts or after a packet of another bandwidth: a 20 ms packet decodes to
936 samples and the next wider packet to 984. sceOpusDecDecode required
exactly the packet's duration and threw, so ProsperoRadio aborted on a
narrowband Opus station.
The decoder now keeps FFmpeg's output in a queue and returns exactly the
packet's duration, as libopus does: the first narrowband packet starts
with 24 samples of silence and the held-back samples follow in the next
calls. The new test decodes three libopus 6 kb/s narrowband packets and
a wideband packet after them; it aborts on main.
