Michael Niedermayer	8617bc6ffa	avcodec/golomb: Fix undefined shifts in unsigned rice decoding code Found-by: Clang -fsanitize=shift Reported-by: Thierry Foucu <tfoucu@google.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	b0ae362a21	avcodec/golomb: use NULL for pointers instead of 0 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Diego Biurrun	91d305790e	get_bits: Rename HAVE_BITS_REMAINING --> BITS_AVAILABLE The HAVE_ prefix is reserved for macros set by configure.	10 years ago
Martin Storsjö	508a84e672	golomb: Fix the implementation of get_se_golomb_long This was only used in hevc muxing code so far. This makes the return values match what get_se_golomb returns for the same bitstream reader instances. The logic for producing a signed golomb code out of an unsigned one was based on the corresponding code in get_se_golomb, which operated directly on the bitstream reader buffer - not on the equivalent return value from get_ue_golomb.

Michael Niedermayer	a92816c4eb	get_se_golomb: fix decoding of very large values Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	fd165ace7b	golomb: check log validity before shifting Fixes invalid right shift in fate-cavs Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Janne Grunau	9a2e79116d	golomb: use unsigned arithmetics in svq3_get_ue_golomb() This prevents undefined behaviour of signed left shift if the coded value is larger than 2^31. Large values are most likely invalid and caused errors or by feeding random. Validate every use of svq3_get_ue_golomb() and changed the place there the return value was compared with negative numbers. dirac.c was clean, fixed rv30 and svq3.	12 years ago

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

Nir Ben David	083d9ba448	golomb: Fix overread in get_ur_golomb_jpegls() Fixes Ticket600 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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().

Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
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	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

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
