* lzo: fix overflow checking in copy_backptr()Xi Wang2013-03-15
| | | | | | | | | | | | | 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.

* Add av_log_{ask_for_sample|missing_feature} replacements to libavutilDiego Biurrun2013-03-13
| | | | | This allows reporting missing features and requesting samples from all libraries in a standard way; with a simplified API.
* atomic: prefer gcc builtins over win32 atomics, if available.Hendrik Leppkes2013-03-11
| | | | | | | 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>
* avframe: copy reordered_opaque in copy_propsJanne Grunau2013-03-11
| | | | Fixes video playback in applications still using reordered_opaque.
* atomic: fix CAS with armcc.Anton Khirnov2013-03-09
| | | | | | 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
* atomic: Exclude the unsupported implementation headers from checkheadersMartin Storsjö2013-03-08

* atomic: Check for __sync_val_compare_and_swap instead of __sync_synchronizeMartin Storsjö2013-03-08
| | | | | | | | | | | | 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>
* atomic: Add include guards to the implementation headersMartin Storsjö2013-03-08
| | | | | | | | 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>

* Move AVFrame from lavc to lavu.Anton Khirnov2013-03-08
| | | | Add AVBuffer-based reference counting API to it.
* lavc: move AVFrame.hwaccel_picture_private to Picture.Anton Khirnov2013-03-08
| | | | | This field is private and should not be present in a public struct. It is only used in DXVA with mpegvideo-based decoders currently.
* AVBuffer: add a new API for buffer poolsAnton Khirnov2013-03-08
|
* lavu: add a new API for reference-counted data buffers.Anton Khirnov2013-03-08
|
* lavu: add support for atomic operations.Ronald S. Bultje2013-03-08
| | | | | | | | | | 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>

* x86: Use simple nop codes for <= sse (rather than <= mmx)Ronald S. Bultje2013-02-19

* avutil: Move emms code to x86-specific headerDiego Biurrun2013-02-14
|
* lavu: avoid clashing definition of ELuca Barbato2013-02-12
| | | | | 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.
* crc: Move static data table from header to .c fileDiego Biurrun2013-02-11
| | | | Having static data tables in header files is a potential source of trouble.
* arm: Fall back to runtime cpu feature detection via /proc/cpuinfoMartin Storsjö2013-02-11
| | | | | | | | | | | | | | | | 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.

* float_dsp: Include config.h for redefining restrictMartin Storsjö2013-01-23
| | | | | | | | 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>
* floatdsp: move scalarproduct_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | This makes the aac decoder and all voice codecs independent of dsputil.
* floatdsp: move butterflies_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.
* floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | | 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.

* x86: Add a Yasm-based emms() replacementMartin Storsjö2013-01-18
