This variable is only used once, so setting it there is clearer.

This reduces code duplication and prevents stale pointers from remaining
on the link.

The buffer is passed on to the next filter, so we shouldn't keep any
pointers to it.

Avoid pointless filter ref/unref. Just use the reference passed to
start_frame().

Directly forwarding the input buffer to the next filter means that
drawtext no longer owns any references to it and thus shouldn't refer to
it in any way.

OpenJPEG can decode in lower resolution or decode only a number
of enhancement layers.

It already skips any extra bytes at the end, and apparently there are some
samples in the wild with larger 'kuki' chunks.

Needs to be done separately for each element.

This will make multi-channel implementation simpler.
Based partially on a patch by Andrew D'Addesio <modchipv12@gmail.com>.

Use get_bits_long() in decode_scalar().
Use unsigned int for decoded value.

Avoids unneeded interleaving and allows for reusing the AVFrame output buffer
as the internal buffer for 24-bit and 32-bit sample size.
