Google Chrome	aedc98b0a4	Check submap indexes. 10_vorbis_submap_indexes.patch by chrome. I am applying this even though Reimar had some comments to improve it as it fixes a serious security issue and I do not want to leave such things unfixed. Originally committed as revision 20001 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Google Chrome	36b7e983a6	Check begin/end/partition_size. 23_vorbis_sane_partition.patch by chrome.

Måns Rullgård	01b2214758	Merge FFTContext and MDCTContext Originally committed as revision 19931 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	1de4ba7155	Make sure that values generated for ff_vorbis_len2vlc in vorbis_parse_setup_hdr_codebooks are in the valid range (<=32). Originally committed as revision 19373 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Siarhei Siamashka	373177949f	Use iMDCT output scaling to simplify ffvorbis and make it slightly faster. Originally committed as revision 18879 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Siarhei Siamashka	7dfed8e1dc	Fix for a problem with inverted sign of output data from ffvorbis decoder. Now the sign of audio samples in ffvorbis output is the same as in original uncompressed audio file and this also allows the use of tiny_psnr to compare ffvorbis with libvorbis/tremor. Originally committed as revision 18878 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
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
Siarhei Siamashka	460c0abfbb	Fix for issue #829 ("ffvorbis outputs crackling sound, libvorbis plays fine") This was off-by-one bug which affects floor0 encoded files. Tracked down by valgrind (was reported as the use of uninitialized memory). With this patch applied, tiny_psnr now reports the following when ffvorbis is compared to libvorbis-1.0beta4 output for 'lsp-test.ogg' sample: stddev: 0.76 PSNR: 98.69 bytes: 3498380/ 3498452 Output from libvorbis-1.2 is substantially different: stddev: 132.57 PSNR: 53.87 bytes: 3498424/ 3498496 Originally committed as revision 18821 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 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. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Loren Merritt	5eb0f2a425	float_to_int16_interleave: change src to an array of pointers instead of assuming it's contiguous. this has no immediate effect, but will allow it to be used in more codecs. Originally committed as revision 14252 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
