Stefano Sabatini	448524777a	Add the M_PHI constant, contains an approximation of the golden ratio irrational number. Originally committed as revision 24439 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Pettenò	3fc548df28	Make ff_inverse stay with libavutil, and optional copy it to libavcodec. The ff_inverse table is used by FASTDIV macro, defined in libavutil, but up to now the table was defined only in libavcodec. After this change, the main copy of ff_inverse is part of libavutil (just like FASTDIV), but if CONFIG_SMALL is unset, then a different copy is made available to libavcodec, to avoid the performance penalty of using an external look up table. Dynamic linking works, because the libraries are linked with -Bsymbolic, so the local copy of the symbol has priority over the external; static linking works because the table is on a standalone object file in both libraries, so the linker is able to discard one of the two. Tested on Linux/x86-64 and Mac OS X/x86-64. Originally committed as revision 24383 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	e6b22522c9	bswap: change ME to NE in macro names Other parts of FFmpeg use NE (native endian) rather than ME (machine). This makes it consistent. Originally committed as revision 24169 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	7918375f88	intreadwrite: common.h is not needed, attributes.h is sufficient Originally committed as revision 24155 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	9699a96a80	Bump minor after read/write_line() to av_read/write_image_line() rename, done in r24101. Originally committed as revision 24128 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	b65c1ccfe1	Change i to unsigned in get_generic_seed(). This is clearer than comparing against an unsigned number to force an unsigned comparison that we need. Originally committed as revision 24114 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	e51f04968e	Restore array sizes in doxygen parameter names. Originally committed as revision 24108 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	c84d5aa74f	get_generic_seed() for the cases without /dev/random and AV_READ_TIME Originally committed as revision 24102 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	ce1cd1cba2	Rename read/write_line() to av_read/write_image_line(). The old names were not av_ prefixed, and they were causing linking failure on many platforms. The new names are also more descriptive. Patch by Stefano Sabatini. Originally committed as revision 24101 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Diego Biurrun	eee9119ad1	Add parameter names to av_log/av_vlog function declarations. Doxygen gets confused without an explicit parameter name. Originally committed as revision 23972 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	9958096ea2	Reindent Originally committed as revision 23931 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	b7fa5c5abb	random_seed: allow to block on /dev/random If both /dev/random and /dev/urandom failed to return data, an uninitialised value might be returned. Since most systems have a non-blocking /dev/urandom or have /dev/random with similar properties, the chance of blocking is minimal, and the alternative of returning non-random data is worse. Originally committed as revision 23930 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Reimar Döffinger	dd025f25da	Change AES code to be strict-aliasing-safe. Makes it give correct results with e.g. gcc 4.4.
