Måns Rullgård	4a051891f6	cosmetics: reformat intreadwrite.h Originally committed as revision 19659 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	63826ceb32	intreadwrite: ensure arch-specific versions are always used if defined The per-arch headers can define any combination of B/L/N variants. This ensures that whatever is defined in an arch header gets used for all equivalents not defined there. E.g. on a little-endian machine, AV_RN and AV_RL should give the same code. Originally committed as revision 19658 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Biurrun	75af07495a	Revert addition of '#undef av_always_inline' to config.h in the small case. Instead, #include config.h at the top of common.h so that av_always_inline does not get doubly defined. Originally committed as revision 19553 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	8b4e7c28fb	Mark conditionally used variable T2 as av_unused; avoids the warning: libavutil/sha.c:183: warning: unused variable `T2' Originally committed as revision 19551 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Alex Converse	291fd18a6e	Add a log2 replacement for systems that haven't quite caught up with the C99 standard library. Originally committed as revision 19395 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	451ae25724	Prepare SHA code to handle SHA-2 as well. For now rename files and functions and leave av_sha1_* functions for compatibility until next major bump. Originally committed as revision 19394 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	0d73abb86a	Rename function to sha1_transform so it won't be confused with SHA-2 transform when it's added. Originally committed as revision 19389 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Ramiro Polla	16c2e21488	Move DECLARE_ALIGNED and DECLARE_ASM_CONST back from lavu/internal.h to lavu/mem.h. Originally committed as revision 19384 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	4b2be143cd	Do not throw compiler error if asm code needs alignment, but we do not know how to do it for this compiler. This removes a dependency of config.h on the DECLARE_* macros. Originally committed as revision 19383 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	300ad6c16e	ARM: use gcc inline asm in bswap.h only when available Originally committed as revision 19311 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Carl Eugen Hoyos	a3a55b7848	Icc does not support attribute flatten, do not try to use it. Originally committed as revision 19286 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Carl Eugen Hoyos	06be9d9d8e	Icc 11.1 does not support attributes force_align_arg_pointer, alloc_size and cold. Originally committed as revision 19282 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jeff Downs	d468ff0fdf	Fix cast of byte buffer to uint32 that was disregarding alignment requirements. Now calculates crc byte at a time until aligned, then continues with uint32 optimized calculation. This fixes crashes during mlp decoding on sparc (at least, maybe others). Originally committed as revision 19160 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Stefano Sabatini	bf7e799c9e	Remove '\p', '\c' and '\e' doxygen markup from doxy, as it should improve plain text doxy readability. See the thread: "[RFC] Should we use doxygen markup?". Originally committed as revision 19122 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Michael Niedermayer	6c2a860875	Add 420,422 and 444 planar 16bit per component pix formats. Originally committed as revision 18636 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	cc078b5d8f	PPC: check for x-form asm constraint support Originally committed as revision 18606 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	9f5ff83f2a	PPC asm for AV_RL*() PPC is normally big endian but has special little endian load/store instructions. Using these avoids a separate byteswap. This makes the vorbis decoder about 5% faster. Not much else uses little-endian read/write extensively. GCC generates horrible PPC code for the default AV_[RW]B64 (which uses a packed struct), so we override it with a plain pointer cast. Originally committed as revision 18602 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	3c55ce039d	ARM asm for AV_RN() ARMv6 and later support unaligned loads and stores for single word/halfword but not double/multiple. GCC is ignorant of this and will always use bytewise accesses for unaligned data. Casting to an int32_t pointer is dangerous since a load/store double or multiple instruction might be used (this happens with some code in FFmpeg). Implementing the AV_[RW] macros with inline asm using only supported instructions gives fast and safe unaligned accesses. ARM RVCT does the right thing with generic code. This gives an overall speedup of up to 10%. Originally committed as revision 18601 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	a6783b8961	Reorganise intreadwrite.h This changes intreadwrite.h to support per-arch implementations of the various macros allowing us to take advantage of special instructions or other properties the compiler does not know about. Originally committed as revision 18600 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	64bde1974b	cosmetics: Rename prn variable to prng (Pseudo Random Number Generator). Originally committed as revision 18422 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	985fdd534f	Give liblzo benchmark conditionals more descriptive names and add convenience definitions along with instructions for changing them. Originally committed as revision 18387 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	e467369278	Add a configure check for lzo1x_999_compress() and compile the lzo test program in libavutil when this function is available. Originally committed as revision 18386 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Olivier Guilyardi	7b09db3522	Implement av_fifo_space(). Patch by Olivier Guilyardi list et samalyse DOT c0m. Originally committed as revision 18321 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
