* pixdesc: add functions for accessing pixel format descriptors.Anton Khirnov2012-10-12
| | | | | | | | Make av_pix_fmt_descriptors table static on next major bump. Making the table public is dangerous, since the caller has no way to know how large it actually is. It also prevents adding new fields to AVPixFmtDescriptor without a major bump.
* Use the new aes/md5/sha/tree allocation functionsMartin Storsjö2012-10-11

* avutil: Add functions for allocating opaque contexts for algorithmsMartin Storsjö2012-10-11
| | | | | | | | | | | | The current API where the plain size is exposed is not of much use - in most cases it is allocated dynamically anyway. If allocated e.g. on the stack via an uint8_t array, there's no guarantee that the struct's members are aligned properly (unless the array is overallocated and the opaque pointer within it manually aligned to some unspecified alignment).

* parseutils-test: various cleanupsMans Rullgard2012-10-11
| | | | | | | | | - make tables static const - remove useless use of compound literal - break long lines - fix a comma/semicolon typo Signed-off-by: Mans Rullgard <mans@mansr.com>
* parseutils: fix const removal warningMans Rullgard2012-10-11
| | | | | | | | | | The const qualifier is still removed although it happens inside the strtol() function so no warning is generated. Fixes: libavutil/parseutils.c:110:11: warning: assignment discards qualifiers from pointer target type Signed-off-by: Mans Rullgard <mans@mansr.com>

* averror: make error values proper negative valuesJanne Grunau2012-10-11
| | | | Fixes stupid mistake in 25227c3a78fefd74bc6ea34032cd49ec8c8d9d85.
* averror: explicitly define AVERROR_* valuesJanne Grunau2012-10-10

* parseutils-test: do not print numerical error codesMans Rullgard2012-10-10
| | | | | | | The error codes differ between systems so printing the value makes the fate test fail on some systems. Signed-off-by: Mans Rullgard <mans@mansr.com>
* avutil: skip old_pix_fmts.h since it is just a listJanne Grunau2012-10-08

* parseutils: fix parsing of invalid alpha valuesMans Rullgard2012-10-06
| | | | | | | | | | An alpha specifier outside the valid range results in a conversion from double to long with undefined result. Range-checking the double and only converting it after it passes avoids this. Fixes fate-parseutils errors on some systems. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Give all anonymously typedeffed structs in headers a nameDiego Biurrun2012-10-06
| | | | Anonymous structs cannot be forward declared and have no benefit.
* parseutils-test: Drop random colors from parsing testDiego Biurrun2012-10-06
| | | | This guarantees stable output for comparing test results.
* x86: get_cpu_flags: add necessary ifdefs around function bodyDiego Biurrun2012-10-04
| | | | | | | ff_get_cpu_flags_x86() requires cpuid(), which is conditionally defined elsewhere in the file. Surrounding the function body with ifdefs allows building even when cpuid is not defined. An empty cpuflags mask is returned in this case.
* x86: Drop CPU detection intrinsicsDiego Biurrun2012-10-04
| | | | | | Now that there is CPU detection in YASM, there will always be one of inline or external assembly enabled, which obviates the need to fall back on CPU detection through compiler intrinsics.
* x86: Add YASM implementations of cpuid and xgetbv from x264Diego Biurrun2012-10-04
| | | | | This allows detecting CPU features with builds that have neither gcc inline assembly nor the right compiler intrinsics enabled.
* x86: cpu: Break out test for cpuid capabilities into separate functionDiego Biurrun2012-10-04
|
* x86: ff_get_cpu_flags_x86(): Avoid a pointless variable indirectionDiego Biurrun2012-10-04

* samplefmt: make av_samples_alloc() initialize the data to silence.Anton Khirnov2012-10-04
| | | | Right now the buffer is zeroed, which does not represent silence for U8(P).

* Allow use of strncpy()Mans Rullgard2012-10-03
| | | | | | | | There are cases where strncpy() does exactly what is required. A blanket ban forces more convoluted solutions to be used in those cases and has been a cause of bugs. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ARM: use numeric ID for Tag_ABI_align_preservedMans Rullgard2012-10-03

* ARM: bswap: drop armcc version of av_bswap16()Mans Rullgard2012-10-02
| | | | | | | This function causes several versions of armcc to miscompile code, and the performance impact is small. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: set Tag_ABI_align_preserved in all asm filesMans Rullgard2012-10-02
| | | | | | | | All our ARM asm preserves alignment so setting this attribute in a common location is simpler. This removes numerous warnings when linking with armcc. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: fix Thumb PIC on AppleMans Rullgard2012-10-02
| | | | | | | LDR with register offset and PC as base register is not available in the Thumb instruction set so the addition must be done separately. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ARM: use 2-operand syntax for ADD Rd, PC in Apple PIC codeMans Rullgard2012-09-21
| | | | | | | The Apple assembler refuses to assemble the 3-operand form in Thumb2 even though it is valid syntax. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: align PIC offset pools to 4 bytesMans Rullgard2012-09-21
| | | | | | | | | When building Thumb2 code, the end of a function, where the PIC offsets are placed, need not be aligned. Although the values are only accessed with instructions allowing unaligned addresses, keeping them aligned is preferable. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: swap source operands in some add instructionsMans Rullgard2012-09-20
| | | | | | This allows using a 16-bit opcode when generating Thumb2 code. Signed-off-by: Mans Rullgard <mans@mansr.com>

* x86: Replace checks for CPU extensions and flags by convenience macrosDiego Biurrun2012-09-08
| | | | | This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.
* x86: float_dsp: fix ff_vector_fmac_scalar_avx() on Win64Justin Ruggles2012-09-07
