Nicolas George	55cc60cd6d	lavu: add thread message API.	11 years ago
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

James Almer	56572787ae	Add Windows resource file support for shared libraries Originally written by James Almer <jamrial@gmail.com> With the following contributions by Timothy Gu <timothygu99@gmail.com> * Use descriptions of libraries from the pkg-config file generation function * Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser) * Use "FFmpeg" for ProductName as MSDN says "name of the product with which the file is distributed" [1]. * Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1]. * Only build the .rc files when --enable-small is not enabled.

Timothy Gu	82b2e9cb1d	build: rename version.h to libavutil/ffversion.h Also the libavutil/ffversion.h will be installed. Rationale: * Applications might want to know FFmpeg's version besides the individual libraries'. * Avoids file name clash between FFmpeg's ./version.h and lib*/version.h when a library source file includes both and is compiled on an out-of-tree build.

Stefano Sabatini	68590650f0	lavu/avstring: add av_utf8_decode() function	11 years ago
Michael Niedermayer	b382d09d29	avutil: reintroduce lls1 as the 52 ABI needs it lls1 taken from `ff130d7` This is incompatible with libavcodec version 55.18.100 to 55.43.100 except 55.39.101 This incompatibility is caused by these libavcodec versions depending on a libavutil 52 which is ABI incompatible with the previous ABI 52 you can avoid this incompatibility by upgrading your libavcodec so it does no longer depend on the invalid ABI See: `502ab21af0` See: `cc6714bb16` See: `41578f70cf` See: Ticket3136 Tested-by: marillat Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Nicolas George	d5b58f678d	tools: add benchmark for crypto functions. The benchmark tests the speed of the following algorithms: MD5, SHA-1, SHA-256, SHA-512, RIPEMD-160, AES-128. It can optionally be built to perform the same benchmark on other crypto libraries, for comparison purposes. The supported libraries are: - crypto: OpenSSL's libcrypto; - gcrypt: GnuTLS's libgcrypt; - tomcrypt: LibTomCrypt To enable them, use this syntax: make VERSUS=crypto+gcrypt+tomcrypt tools/crypto_bench They do not need to have been enabled in configure.	11 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.
