* * Allocating 16 bytes more for the MEMALIGN_HACK is enough. There's noHerve W2006-06-301-3/+5
| | | | | | | | | | | | | | | | | need for 1 more extra byte. * Checking whether the to be allocated size is larger than INT_MAX, doesn't assure that size+16 bytes for the MEMALIGN_HACK isn't larger than INT_MAX. * malloc might return NULL. Checking for it before using that pointer seems like a good idea. Patch by Herve W.

* flacenc - rice param search patch by (Justin Ruggles jruggle earthlink netJustin Ruggles2006-06-271-101/+305
| | | | | | | | | | | | | | | | | | | | | | | 1) search for optimal rice parameters and partition order. i also modified the stereo method estimation to use this to calculate estimated bit count instead of using just the pure sums. 2) search for the best fixed prediction order 3) constant subframe mode (good for encoding silence) Note that the regression test for the decoded wav file also changed. This is due to FFmpeg's FLAC decoder truncating the file, which it did before anyway...just at a different cutoff point. The generated FLAC files are still 100% lossless. With this update, FFmpeg's FLAC encoder has speed and compression somewhere between "flac -1" and "flac -2". On my machine, it's about 15% faster than "flac -2", and about 10% slower than "flac -1". The encoding parameters are identical to "flac -2" (fixed predictors, 1152 blocksize, partition order 0 to 3). Originally committed as revision 5536 to svn://svn.ffmpeg.org/ffmpeg/trunk
