Diego Biurrun	92db508307	build: Generate pkg-config files from Make and not from configure This moves work from the configure to the Make stage where it can be parallelized and ensures that pkgconfig files are updated when library versions change. Bug-Id: 449	8 years ago
Wan-Teh Chang	2170017a1c	avutil: fix data race in av_get_cpu_flags() Make the one-time initialization in av_get_cpu_flags() thread-safe. The static variables \|flags\|, \|cpuflags_mask\|, and \|checked\| in libavutil/cpu.c are read and written using normal load and store operations. These are considered as data races. The fix is to use atomic load and store operations. Remove the \|checked\| variable because the invalid value of -1 for \|flags\| can be used to indicate the same condition. Rename \|flags\| to \|cpu_flags\| and move it to file scope. The fix can be verified by running the libavutil/tests/cpu_init.c test program under ThreadSanitizer: ./configure --toolchain=clang-tsan make libavutil/tests/cpu_init libavutil/tests/cpu_init There should be no warnings from ThreadSanitizer. Co-author: Dmitry Vyukov of Google, who suggested the data race fix. Signed-off-by: Wan-Teh Chang <wtc@google.com>	8 years ago
Vittorio Giovara	c70add61d1	lavu: Add AVSphericalMapping type and frame side data While no decoder currently exports spherical information, this type represents a frame property that has to be passed through from container to frames.

Vittorio Giovara	bddd8cbf68	Add transformation matrix API. Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and frame side data (respectively) to describe a display transformation matrix for linear transformation operations on the decoded video. Add functions to easily extract a rotation angle from a matrix and conversely to setup a matrix for a given rotation angle. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 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

Anton Khirnov	c6b25d1d5e	Revert "avutil: Add a copy of ff_sqrt_tab back into avutil to restore ABI compatibility" This reverts commit `d15c21e5fa`. After the major bump this is no longer necessary.	12 years ago
Martin Storsjö	d15c21e5fa	avutil: Add a copy of ff_sqrt_tab back into avutil to restore ABI compatibility Earlier versions of for instance of libavcodec expect this symbol to be present in libavutil. This commit can be reverted after the next major bump. New shared builds of avcodec will link to the internal copy of the table within that library, so those builds won't rely on this table being present in avutil any longer either.

Mans Rullgard	8c0a3d5fe0	avutil: remove inline av_log2 from public API This removes inline av_log2 and av_log2_16bit from the public API, instead exporting them as regular functions.

Mans Rullgard	84e65c763d	build: simplify enabling of compat objects Add a configure function to pull in a compat object and set up redirects in one operation. This avoids duplicating conditions across configure and makefiles. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
