Anton Khirnov	2c328a9079	pixdesc: add a function for counting planes in a pixel format.	12 years ago
Anton Khirnov	4d67ff8e8e	AVOptions: fix using named constants with child contexts. The named constant needs to be searched for in the same object on which the option is set, i.e. target_obj.	12 years ago
Anton Khirnov	9676b9a2cd	AVOption: remove an unused function parameter.	12 years ago
Xi Wang	ca6c3f2c53	lzo: fix overflow checking in copy_backptr() The check `src > dst' in the form `&c->out[-back] > c->out' invokes pointer overflow, which is undefined behavior in C. Remove the check. Also replace `&c->out[-back] < c->out_start' with a safe form `c->out - c->out_start < back' to avoid overflow.

Diego Biurrun	f099d3d1d5	Add av_log_{ask_for_sample\|missing_feature} replacements to libavutil This allows reporting missing features and requesting samples from all libraries in a standard way; with a simplified API.	12 years ago
Hendrik Leppkes	d6d369bf13	atomic: prefer gcc builtins over win32 atomics, if available. The mingw win32 atomics appear to be faulty, so they should not be used if the gcc ones are available. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Janne Grunau	fc8406d01e	avframe: copy reordered_opaque in copy_props Fixes video playback in applications still using reordered_opaque.	12 years ago
Anton Khirnov	6327c10702	atomic: fix CAS with armcc. On the current code, armcc will fail with: "libavutil/atomic_gcc.h", line 52: Error: #2771: first argument must be a pointer to integer or enumeration type	12 years ago
Martin Storsjö	666fe5da47	atomic: Exclude the unsupported implementation headers from checkheaders Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	e460aa3282	atomic: Check for __sync_val_compare_and_swap instead of __sync_synchronize Not all gcc configurations have an implementation of all the atomic operations, and some gcc configurations have some atomic builtins implemented but not all. Thus check for the most essential function, whose presence should indicate that all others are present as well, since it can be used to implement all the other ones. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	2240e92f05	atomic: Add include guards to the implementation headers This makes them pass standalone compilation tests. Previously, they included atomic.h which included themselves again, leading to double definitions. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	0651e892e1	Replace remaining includes of audioconvert.h with channel_layout.h	12 years ago

Anton Khirnov	77b2cd7b41	AVFrame: add side data.	12 years ago
Anton Khirnov	7ecc2d403c	Move AVFrame from lavc to lavu. Add AVBuffer-based reference counting API to it.	12 years ago
Anton Khirnov	ad0c9f2d5d	lavc: move AVFrame.hwaccel_picture_private to Picture. This field is private and should not be present in a public struct. It is only used in DXVA with mpegvideo-based decoders currently.	12 years ago
Anton Khirnov	1cec0624d0	AVBuffer: add a new API for buffer pools	12 years ago
Anton Khirnov	8e401dbe90	lavu: add a new API for reference-counted data buffers.	12 years ago
Ronald S. Bultje	65f1d45dcc	lavu: add support for atomic operations. These could be used for reference counting, or for keeping track of decoding progress in references in multithreaded decoders. Support is provided by gcc/msvc/suncc intrinsics, with a fallback using pthread mutexes. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago

Diego Biurrun	c9ad5f59aa	intreadwrite: tomi: Add missing attributes.h #include for av_always_inline	12 years ago
Ronald S. Bultje	0c0828ecc5	x86: Use simple nop codes for <= sse (rather than <= mmx) The "CentaurHauls family 6 model 9 stepping 8" family of CPUs (flags: fpu vme de pse tsc msr cx8 sep mtrr pge mov pat mmx fxsr sse up rng rng_en ace ace_en) SIGILLs on long nop codes.

Diego Biurrun	ab441e20ff	avutil: Move emms code to x86-specific header	12 years ago
Luca Barbato	fd1abf4269	lavu: avoid clashing definition of E E is usually defined as a shorthand for AV_OPT_FLAG_ENCODING_PARAM. Rename the single expansion E(x) now used in libavutil to E1.	12 years ago
Diego Biurrun	62a43d30cc	crc: Move static data table from header to .c file Having static data tables in header files is a potential source of trouble.	12 years ago
Martin Storsjö	ab8f1a6989	arm: Fall back to runtime cpu feature detection via /proc/cpuinfo On recent android versions, /proc/self/auxw is unreadable (unless the process is running running under the shell uid or in debuggable mode, which makes it hard to notice). See http://b.android.com/43055 and https://android-review.googlesource.com/51271 for more information about the issue. This makes sure e.g. neon optimizations are enabled at runtime in android apps even when built in release mode, if configured to use the runtime detection.

Martin Storsjö	2e4130037c	float_dsp: Include config.h for redefining restrict This makes sure that the restrict keyword is mapped to whatever keyword the compiler prefers/supports. This fixes building on MSVC (and possibly on GCC 2.x as well). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	d56668bd80	floatdsp: move scalarproduct_float from dsputil to avfloatdsp. This makes the aac decoder and all voice codecs independent of dsputil.	12 years ago
Ronald S. Bultje	5959bfaca3	floatdsp: move butterflies_float from dsputil to avfloatdsp. This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.	12 years ago
Ronald S. Bultje	42d3246948	floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.	12 years ago
Ronald S. Bultje	55aa03b9f8	floatdsp: move vector_fmul_add from dsputil to avfloatdsp.	12 years ago
Martin Storsjö	f4facd2ce7	x86: Add a Yasm-based emms() replacement This provides a fallback when building with Yasm enabled, but neither inline assembly, nor the _mm_empty intrinsic are available or enabled. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
