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].

Michael Niedermayer	aa264da5bf	adpcmenc: Calculate the IMA_QT predictor without overflow Previously, the value given to put_bits was 10 bits long for positive predictors, even though 9 bits were to be written. The extra bit could in some cases overwrite existing bits in the bitstream writer cache. This fixes a failed assert in put_bits.h, when running a version built with -DDEBUG. The fate test result gets slightly improved, thanks to getting rid of the overwritten bits in the bitstream writer cache. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Justin Ruggles	5d4ef004bf	adpcm_swf: Use correct sample offsets when using trellis. Fixes invalid reads when encoding mono streams when trellis is used.	13 years ago

Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Justin Ruggles	24e74f0a0f	adpcmenc: update to AVCodec.encode2()	13 years ago
Justin Ruggles	770a5c6d02	adpcmenc: Use correct frame_size for Yamaha ADPCM. Output packet size should match avctx->block_align. The target output packet size is 1024 bytes. Before: mono - 1024 samples -> 512 bytes stereo - 2048 samples -> 2048 bytes After: mono - 2048 samples -> 1024 bytes stereo - 1024 samples -> 1024 bytes	13 years ago
