Siarhei Siamashka	7d485f165f	Support for getting (i)MDCT output multiplied by a constant scaling factor. Scaling (i)MDCT output has no runtime overhead and can be used to improve performance of audio codecs. All the changes are only needed in 'ff_mdct_init' function and slow down initialization a bit. Originally committed as revision 18855 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	110baa2e99	Remove unused variable from wma_decode_block() found by CSA. Originally committed as revision 18568 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.

Reimar Döffinger	4c1e509c11	wma_decode_superframe always returns s->block_align, so make sure we actually consume exactly that amount. Fixes sound artefacts (mostly blips) that mysteriously disappeared after e.g. remuxing with mencoder. Originally committed as revision 11115 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Benjamin Larsson	e7a6d5f313	Bug fix for crashes when SSE is used on unaligned arrays. No measureable change in speed. This gave random crashes on Win32 and BeOS. The cause for this bug is that gcc doesn't align the stackframe. Linux and glibc always ensure this to be true thus this never affected Linux.
