Justin Ruggles	4795362660	golomb: check remaining bits during unary decoding in get_ur_golomb_jpegls() Fixes infinite loop in FLAC decoding in case of a truncated bitstream due to the safe bitstream reader returning 0's at the end. Fixes Bug 310. CC:libav-stable@libav.org	13 years ago
Michael Niedermayer	28e4f906fa	golomb: use av_assert Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	46b3fbc30b	golomb: use HAVE_BITS_REMAINING() macro to prevent infloop on EOF. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	52e4018be4	flac: fix infinite loops on all-zero input or end-of-stream. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	c6643fddba	golomb: avoid infinite loop on all-zero input (or end of buffer). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Mans Rullgard	fdba370f8a	h264: fix HRD parameters parsing The bit_rate_value_minus1 and cpb_size_value_minus1 elements allow a wider range than get_ue_golomb() supports. This adds a get_ue_golomb_long() function supporting up to 31 leading zeros, which is the maximum for these syntax elements, and uses it in decode_hrd_parameters().

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Lars Täuber	6fa6c481b9	Make get_ur_golomb capable of reading 16 bit values. Patch by Lars Täuber: firstname taeuber gmx net Originally committed as revision 19821 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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
Stefano Sabatini	b275500706	Split bitstream.h, put the bitstream writer stuff in the new file put_bits.h. Originally committed as revision 18461 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	d4f2a6250a	Fix get_ur_golomb_jpegls() with A32_BITSTREAM_READER If k==0, log==0 can indicate that the coded value uses more than MIN_CACHE_BITS bits. With MIN_CACHE_BITS==32, the fast branch is incorrectly taken in this case unless explicitly forbidden. Originally committed as revision 17550 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	9392863d1b	Clarify get_ue_golomb_31() behavior with >31. Originally committed as revision 17429 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

Michael Niedermayer	631e8afb8c	Correct the threshold of get_ur_golomb_jpegls() at which the optimized case is used. Fix issue245. Originally committed as revision 15334 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	6647ab80e3	bitstream: move put_sbits() from flacenc.c to bitstream.h and use it throughout libavcodec. Originally committed as revision 14204 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	ac2570a8b0	flac fixes: fix data types of residual&decoded fix twos complement bitfields fix utf8 (no, utf8 is not the same as the simple and compact uvlc used in nut) add truncated bitstream support, both ogg and flac demuxers in mplayer cvs provide incomplete frames, and furthermore it isnt possible to find frameboundaries in flac without decoding it completly add escape-less golomb rice decoder (=flac style golomb rice) (ultra efficient, the longest vlc code is just 2^32-1 bits) printf->av_log fix bps for non independant channels fix a few +-1 bugs fix sample order for independant channels fix data_size Originally committed as revision 2791 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
