Make it uniform with the other protocols.

Introduced in 93370d12

This makes sure errors in setting stream parameters are passed
on to the caller. This avoids successfully opening files while
some parameters aren't filled in properly.

We read 2 bytes for 15 out of 16 pixels, therefore we need to
have at least 30 bytes, not 16.

Previously, we returned 0, meaning successful decoding but 0
bytes consumed, leading to an infinite loop.

If the input buffer contains more data after the deflate stream,
the loop previously left running infinitely, with inflate returning
Z_STREAM_END.

This avoids setting a negative number of frames, ending up with a

AVERROR(EAGAIN) and switch back to the audio stream.

an array allocated to hold 'max_samples_per_frame' elements.

Even if the sample rate is valid, an invalid bitrate could

This avoids divisions by zero later (and possibly assertions in
time base scaling), since an invalid rate_flag combined with an
invalid bitrate below could pass the mode combination test.
