Zane van Iperen 9e89a23eac avcodec/adpcm_swf: remove memory allocation during trellis encoding 
The block size is hardcoded, so the buffer size is always known.
Statically allocate the buffer on the stack.

Dyami Caliri 50833c9f7b Fix buffer_size argument to init_put_bits() in multiple encoders. 
Several encoders were multiplying the buffer size by 8, in order to get
a bit size. However, the buffer_size argument is for the byte size of
the buffer. We had experienced crashes encoding prores (Anatoliy) at
size 4096x4096.

Martin Storsjö 0776e0ef6b adpcm: Write the proper predictor in trellis mode in IMA QT 
The actual predictor value, set by the trellis code, never
was written back into the variable that was written into
the block header. This was accidentally removed in b304244b.

This significantly improves the audio quality of the trellis
case, which was plain broken since b304244b.

Encoding IMA QT with trellis still actually gives a slightly
worse quality than without trellis, since the trellis encoder
doesn't use the exact same way of rounding as in
adpcm_ima_qt_compress_sample and adpcm_ima_qt_expand_nibble.

Martin Storsjö 3d79d0c93e adpcm: Avoid reading out of bounds in the IMA QT trellis encoder 
This was broken in 095be4fb - samples+ch (for the previous
non-planar case) equals &samples_p[ch][0]. The confusion
probably stemmed from the IMA WAV case where it originally
was &samples[avctx->channels + ch], which was correctly
changed into &samples_p[ch][1].
