* adpcm: Write the proper predictor in trellis mode in IMA QTMartin Storsjö2014-06-10
| | | | | | | | | | | | | | | | | 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.

* adpcm: Avoid reading out of bounds in the IMA QT trellis encoderMartin Storsjö2014-06-06
| | | | | | | | | | | 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].

* adpcmenc: ensure calls to adpcm_ima_compress_sample() are in the right orderJustin Ruggles2012-10-07
| | | | Should fix fate-acodec-adpcm-ima_wav with several compilers.
* adpcmenc: use planar sample format for adpcm_ima_wav and adpcm_ima_qtJustin Ruggles2012-10-06

* adpcmenc: move 'ch' variable to higher scopeJustin Ruggles2012-10-06
| | | | It is used for multiple codecs.

* adpcmenc: Calculate the IMA_QT predictor without overflowMichael Niedermayer2012-09-04
| | | | | | | | | | | | | | 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>

* adpcmenc: Use correct frame_size for Yamaha ADPCM.Justin Ruggles2012-02-20
| | | | | | | | | | | 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

|
* adpcmenc: fix adpcm_ms extradata allocationJustin Ruggles2012-01-30
| | | | | | Add FF_INPUT_BUFFER_PADDING_SIZE. If allocation fails, also free memory which was allocated previously in adpcm_encode_init().
