Herve W	a949360163	* Allocating 16 bytes more for the MEMALIGN_HACK is enough. There's no 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.

Reimar Döffinger	c6bb50e002	Fix initialization of vc1_decoder (the same as wmv3_decoder). Patch by Reimar Doeffinger. Originally committed as revision 5544 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Kostya Shishkov	87dfe848fa	Some optimization and fixes - mostly reworked MC and bitplanes. Originally committed as revision 5543 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Kostya Shishkov	e8ba1cea3c	This should make P-frames decoding work on x86 (by avoiding get_bits(0)) Originally committed as revision 5542 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Justin Ruggles	e71bcc3798	flacenc - rice param search patch by (Justin Ruggles jruggle earthlink net 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	19 years ago
Kostya Shishkov	f26c2ef53b	Added loop filtering as ersatz for overlap filter (improves picture quality for coarse quantization). Originally committed as revision 5535 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Reimar Döffinger	0b52626eb0	Do not read full byte when less than 8 bits are still to be read. Does not make a difference with any of my samples, but current code does not make much sense. Originally committed as revision 5533 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Måns Rullgård	4f8ff17e75	The AAC frame header uses 13 bits for the frame size, so the buffer should have room for such a frame. A frame that large seems unlikely in a valid file, but leaving room for it spares us the need to check it elsewhere. Moving the buffer to the end of the struct made debugging this easier.
