* arm: Use .data.rel.ro for const data with relocationsMartin Storsjö2014-12-09
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: enable vda hwaccel by defaultVittorio Giovara2014-12-03
| | | | | Following the old thread suggestions. Vittorio
* lavf: Use MoveFileEx instead of rename/_wrename on windowsMartin Storsjö2014-11-27
| | | | | | | | | This allows getting the normal unix semantics, where a rename allows replacing an existing file. Based on a suggestion by Reimar Döffinger. Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Fix enabling memalign_hack automaticallyMartin Storsjö2014-11-18
| | | | | | | | | simd_align_16 is a configure item that can be enabled or disabled, it's not a variable containing a list of other configure items as need_memalign previously. This was broken in eba2233b5. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: Add an MPEG-DASH ISOFF segmenting muxerMartin Storsjö2014-11-17
| | | | | | | | | | | | | | | | | | This is mostly to serve as a reference example on how to segment the output from the mp4 muxer, capable of writing the segment list in four different ways: - SegmentTemplate with SegmentTimeline - SegmentTemplate with implicit segments - SegmentList with individual files - SegmentList with one single file per track, and byte ranges The muxer is able to serve live content (with optional windowing) or create a static segmented MPD. In advanced cases, users will probably want to do the segmenting in their own application code. Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Check only for xcbLuca Barbato2014-10-28
| | | | xcb-utils are not needed anymore.
* xcbgrab: XCB-based screen captureLuca Barbato2014-10-26
| | | | Matches the x11grab screen capture by features.
* lavu: Provide fallbacks for gmtime_r and localtime_rMartin Storsjö2014-10-26
| | | | | | | | | | | | This allows writing most code as if they always are is available. These are ok to use from other libraries even though it's not a public header, since they only provide an inline declaration, and doesn't add an actual dependency on lavu internals. (This can be considered more a build system compatibility fallback than a libavutil feature.) Signed-off-by: Martin Storsjö <martin@martin.st>
* w32pthreads: use the CONDITION_VARIABLE typedef if availableJames Almer2014-10-10
| | | | | | | | This silences warnings about passing arguments from incompatible pointer type when targeting Windows Vista or newer. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Add -lrt dependency to avutil's pc file.Josh Allmann2014-10-04
| | | | | | This is needed for clock_gettime. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* configure: Provide a safe default for unknonw libcsLuca Barbato2014-09-27
| | | | | | | Support musl out of box. Amend commit 9d2cee52d37c7340f85a5d41110282aac03e6855 that got wrongly merged in its stead.
* configure: Assume a standard-compliant default libcLuca Barbato2014-09-26
| | | | | Non-standard compliant libc should be supported on a per-case basis anyway.
* configure: Use the right variables in check_host_cppJörg Krause2014-09-17
| | | | | | HOSTCPPFLAGS and HOSTCFLAGS are only set in config.mak. Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Disable i686 for i586 and lower CPUsMikulas Patocka2014-09-16

* configure: Split adding of CFLAGS and CPPFLAGS for hardened toolchainDiego Biurrun2014-09-16
|
* Split off floating point AAN (I)DCT into separate componentsDiego Biurrun2014-09-07
|
* build: Split WMA frequencies into a separate object fileDiego Biurrun2014-09-04
| | | | | These are the only WMA bits shared with binkaudio. Splitting them off reduces the binnkaudio dependency on general WMA code.
* time: Use clock_gettime if the monotonic clock is availableLuca Barbato2014-09-03
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* configure: add --enable-rpathReinhard Tartler2014-08-23
| | | | | | | | | | | | | This option facilitates testing shared libarary builds: for instance fate builders do no longer need to set LD_LIBRARY_PATH as the binaries will get the right search paths hardcoded into their executable file. This option is only meant to be used for testing purposes: The installed libraries must not move around in the file system, and doing so will cause a lot of subtle problems. For more information why using RPATH is dangerous, please refer to https://blog.flameeyes.eu/2010/06/the-why-and-how-of-rpath
* ogg: Provide aliases for Speex, Opus and audio-only oggLuca Barbato2014-08-22
| | | | Since they are aliases for ogg enabling any of them enables ogg as well.
* configure: Suppress "potentially uninitialized variable" warnings from MSVCDiego Biurrun2014-08-21
| | | | The same is done for GCC and clang already.
* configure: Check for nanosleep in headers as well, not only in libsMartin Storsjö2014-08-13
| | | | | | | | | On mingw64 with c++11 support, the link libraries do contain a nanosleep function, while it isn't exposed via the headers. Using check_func_headers instead of a plain check_func fixes this misdetection. Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Don't pass MSVC compiler options -M[TD] to armasmMartin Storsjö2014-08-10
| | | | | | | | | | | The -MD option (for enabling a dynamically linked crt) gets interpreted as a cpp option for generating dependency information (into a file named '-.d', when preprocessing to a pipe). We shouldn't be passing any and all C compiler flags to armasm (which is a plain assembler, only with cpp bolted on via gas-preprocessor), but these are the main conflicting ones. Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Suggest upgrading gas-preprocessor instead of just installingMartin Storsjö2014-08-10
| | | | | | Older versions don't support all the features we test for now. Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Enable gas-preprocessor on all OSes but only if availableDiego Biurrun2014-08-10
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Add probe identification of MS armasmMartin Storsjö2014-08-10
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Only run gas checks on ARM and PowerPCDiego Biurrun2014-08-08
| | | | Standalone GNU assembly is not used on x86.
* configure: Die if gas is unavailable under aarch64 as well as ARMDiego Biurrun2014-08-08

* configure: Include the armcc build number in the compiler identificationMartin Storsjö2014-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | This tries to find the most expressive part of the output of armcc --vsn to include, giving a compiler identification of "ARM Compiler 5.04 update 2 (build 82)" instead of just "ARM Compiler 5.04" for armcc 5.0. 4.x versions of armcc output the following, for "armcc --vsn": ARM C/C++ Compiler, RVCT4.0 [Build 925] For evaluation purposes only Software supplied by: ARM Limited ARM C/C++ Compiler, 4.1 [Build 894] For evaluation purposes only Software supplied by: ARM Limited 5.0 versions output this: Product: ARM Compiler 5.04 Component: ARM Compiler 5.04 update 2 (build 82) Tool: armcc [5040081] For evaluation purposes only Software supplied by: ARM Limited Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: check $as first before using $gas as GNU asJanne Grunau2014-08-05
| | | | | | | | llvm's integrated assembler supports the AArch64 asm on darwin since August 2014. So check $as first before using gas-preprocessor.pl via $gas. Makes the checks specific for that the architecture specific asm needs. PPC Altivec and AArch64 needs on ':vararg' for macro arguments. Arm needs in addition the '.altmacro' directive.
* vc-1: Add platform-specific start code search routine to VC1DSPContext.Ben Avison2014-08-04
| | | | | | | Initialise VC1DSPContext for parser as well as for decoder. Note, the VC-1 code doesn't actually use the function pointer yet. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* h264: Move start code search functions into separate source files.Ben Avison2014-08-04
| | | | | | This permits re-use with parsers for codecs which use similar start codes. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* Add Icecast protocolMarvin Scholz2014-08-04
| | | | | | Icecast is basically a convenience wrapper around the HTTP protocol. Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Globally add ZLIB_CONST to CPPFLAGS if zlib is enabledDiego Biurrun2014-07-30
|
* configure: Use require_pkg_config for SpeexLuca Barbato2014-07-28
| | | | | Distributors and integrators nowadays have less problems by leveraging pkg-config files than having to set custom CFLAGS and LDFLAGS.
* configure: Extend the neon intrinsics checkMartin Storsjö2014-07-22
| | | | | | | Check for an instruction that causes the (very old) Apple GCC 4.2 to error out ("unrecognizable insn"). Signed-off-by: Martin Storsjö <martin@martin.st>
