* build: Support building using clang-usan and disable-optimizationKaterina Barone-Adesi2014-05-16
| | | | | | | | | | Clang Undefined Behaviour Sanitizer seems to make non-constant constant expressions, making the compilation fail when they are used within inline assembly if no optimization is requested. Add -O1 to the cflags to hide the misbehaviour. Bug-Id: 683
* configure: fix enable-libopus help stringTristan Matthews2014-05-15

* lavc: add a native Opus decoder.Anton Khirnov2014-05-15
| | | | | | | | | | | | | Initial implementation by Andrew D'Addesio <modchipv12@gmail.com> during GSoC 2012. Completion by Anton Khirnov <anton@khirnov.net>, sponsored by the Mozilla Corporation. Further contributions by: Christophe Gisquet <christophe.gisquet@gmail.com> Janne Grunau <janne-libav@jannau.net> Luca Barbato <lu_zero@gentoo.org>
* build: handle library dependencies in configureJanne Grunau2014-05-13
| | | | | Instead of setting FFLIBS in each library Makefile configure exports FFLIBS-$library in config.mak.
* lavc: Add new VDA hwaccelAnton Khirnov2014-05-11
| | | | | | | | | It leverages the new hwaccel 1.2 features: - get_buffer2 is never called - the internal context is automatically initialized/deinitialized Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* configure: rework dxva in avconv handlingAnton Khirnov2014-04-28
| | | | | | | Move the dxva check after the dependencies have been detected, make sure the ole32 library exists. Fixes build on non-Windows.

| | | | | | | The first line of the "armcc --vsn" output in one version is "Product: ARM Compiler 5.04". Signed-off-by: Martin Storsjö <martin@martin.st>
* drawtext: Add fontconfig supportLuca Barbato2014-04-17
| | | | | | Introduce the `font` option and make it optional to pass a fontfile. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* libx265: Bump version requirementDerek Buitenhuis2014-03-31
| | | | | | | | | | | Build 13 has a crucial fix which makes x265_encode_headers work as its always been documented. Previous to this, the check was incorrect. Also allows for use of the repeat headers flag. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* build: Add config option for CABAC codeDiego Biurrun2014-03-24
| | | | This allows for more elegant dependency and object declarations.
* configure: Remove dcbzl check for e500v1 and e500v2 architecturesPeter Krefting2014-03-24
| | | | | | | | | | | | The DCBZL instruction is not available for the e500v1 and e500v2 architectures, but may still be recognized by the toolchain, so we need to explicitly disable it for these architectures.

* build: h264 parser depends on full h264 decoderLuca Barbato2014-03-23

* configure: Always use -DOPJ_STATIC when checking for openjpegLuca Barbato2014-03-23
| | | | | | Unbreaks windows systems not providing pkgconf files. Reported-By: Rafaël Carré <funman@videolan.org>
* dsputil: Move thirdpel-related bits into their own contextDiego Biurrun2014-03-22
|
* configure: ppc: Disable ldbrx instruction by defaultDiego Biurrun2014-03-19
| | | | | Only enable it for CPUs that support it. This restores the behavior prior to 7a650caf.
* mpegvideo: move ff_draw_horiz_band() to mpegutils.cVittorio Giovara2014-03-16
| | | | Drop the mpegvideo dependency for svq3 in configure.
* configure: Split some logical blocks off from HAVE_LISTDiego Biurrun2014-03-14

* configure: Split some logical blocks off from CONFIG_LISTDiego Biurrun2014-03-14
|
* configure: Group and sort function/struct/type checksDiego Biurrun2014-03-14
| | | | | Group checks into logical groups and sort alphabetically within those groups unless checks have close coupling. Keep closely coupled checks together.
* Remove all SPARC architecture optimizationsDiego Biurrun2014-03-13
| | | | | SPARC is no longer being used in any multimedia-related fields and the VIS optimizations only represent a maintenance burden.
* build: Record dependency of eatqi decoder on dsputilDiego Biurrun2014-03-13
|
* configure: Add explicit dsputil dependency to mpegvideoencDiego Biurrun2014-03-13
| | | | | Previously, it was an implicit dependency through mpegvideo. Change this, as implicit dependencies can cause all sorts of trouble.
* ffv1: Drop bogus dependency on dsputilDiego Biurrun2014-03-13
| | | | ffv1 does not use any part of the dsputil framework.

* configure: Support older version of openjpeg1Luca Barbato2014-03-12
| | | | | It should work best for debian stable and people not installing the .pc file.
* configure: Group toolchain options together in help outputDiego Biurrun2014-03-12
|
* configure: Provide --pkg-config-flagsLuca Barbato2014-03-11
| | | | | | | Should be used only to pass extra flags to pkgconf invocation, e.g. --static. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* configure: Document --pkg-config optionLuca Barbato2014-03-11

* configure: miscellaneous cosmeticsDiego Biurrun2014-03-10
| | | | | Sort lists of components. Add some whitespace where it helps readability. Consistently use double instead of single quotes around component lists.
* configure: Use the right pkgconf file for openjpegLuca Barbato2014-03-10
| | | | The current release of version 1 uses libopenjpeg1.
* Work around broken floating point limits on some systems.Anton Khirnov2014-03-10
| | | | | | | | | | | | | The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl libc, some BSD flavours) are not exactly representable, i.e. (double)DBL_MAX == DBL_MAX is false This violates (at least some interpretations of) the C99 standard and breaks code (e.g. in vf_fps) like double f = DBL_MAX; [...] if (f == DBL_MAX) { // f has not been changed yet [....] }
* timer: use mach_absolute_time as high resolution clock on darwinJanne Grunau2014-03-09
| | | | | | | | | | Not guaranteed to be in nanosecond resolution. On iOS 7 the duration of one tick is 125/3 ns which is still more than an order of magnitude better then microseconds. Replace decicycles with the neutral UNITS. Decicycles is strange but tenths of a nanosecond and unspecific "deci"-ticks for mach_absolute_time is just silly.

* build: Let the SVQ3 decoder depend on the H.264 decoderDiego Biurrun2014-03-06
| | | | | | | The SVQ3 decoder reuses large parts of the H.264 decoder so it makes no sense to enable the former but not the latter. Also drop unnecessary h263.o object from SVQ3 decoder object list.
* configure: Split x86 SIMD architecture extensions into separate listDiego Biurrun2014-03-06
| | | | | This avoids checking inline/external assembly dependencies for x86 extensions that do not play a role in inline/external assembly.
* configure: enable PIC on s390(x)Reinhard Tartler2014-03-04
| | | | | | | | The s390 architecture requires shared libraries to be built in PIC mode. Otherwise applications will get wrong relocations at run-time, leading to confusing segmentation faults. CC: libav-stable@libav.org
* vf_frei0r: refactor library loading from env variableVittorio Giovara2014-03-04
| | | | strtok_r is not needed any more, so remove it from configure.
