Michael Niedermayer	9386f334af	avcodec/bitstream: Dont try to free buffers for static VLCs Such buffers are not malloced thus freeing would be bad.

Michael Niedermayer	a9903f7ec1	Revert "bitstream: make vlc init of static tables thread safe." This reverts commit `4b6869d6e0`. Conflicts: libavcodec/bitstream.c This code can cause assertion failures on artificial OOM situations It will be replaced by a solution that doesnt have this issue in the following commits.

Loren Merritt	f39ab2071f	change a variable-length array to a malloc. Originally committed as revision 23103 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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

Måns Rullgård	4c4e746566	Avoid negative shifts in build_table() A shift by a negative amount has undefined behaviour. Even though the result of this shift is never used, the shift itself could cause an exception of some kind. Originally committed as revision 21939 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	587edd6af8	Use more consistent / meaningful parameter names for the ff_copy_bits() function. Originally committed as revision 20663 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	ef530829f8	Remove ff_realloc_static, it is no longer used and since it was declared static there is no reason to wait for a major version bump, removing it does not change ABI in any way, not even the non-public one. Originally committed as revision 20023 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	1e224c5480	Reindent. Originally committed as revision 20022 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	e518a49f34	Remove a piece of code left-over from the removed alloc'd static vlc table code. Originally committed as revision 20021 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	595324e143	Completely remove INIT_VLC_USE_STATIC, it is deprecated since ages and finally no longer used anywhere. Originally committed as revision 20013 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	ec62d942ea	Fix potentially unaligned accesses in ff_copy_bits() A pointer should never be assigned a value which may have less than the required alignment of the target type. Compilers may assume pointer values have the required alignment, and emit normal load/store instructions. Unaligned pointers should use a character type or compiler-specific type modifiers. Originally committed as revision 19318 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	fb53b4a035	Rename pbBufPtr() to put_bits_ptr(). The new name is more readable and consistent with the FFmpeg naming style. Originally committed as revision 18497 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
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
Stefano Sabatini	54b02ccda2	Rename the 'put_zero' parameter of ff_put_string() to 'terminate_string'. Originally committed as revision 18442 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
