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	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	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

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.

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
