* configure: add linker export script support on DarwinRodger Combs2016-10-04
| | | | | | | | | | | | | | | This isn't a "version script" in the usual sense, since it doesn't set symbol versions directly. Instead, the version for the whole .dylib is set in the linker flags, and we generate a list of symbol patterns to export. This allows us to keep our local symbols (e.g. ff_*) local on the platform. The Darwin linker's exported_symbols_list format is a bit different than the one used by the GNU linker. It doesn't handle local symbols at all, since when a list is provided, all unlisted symbols are local by default; thus, we remove local sections. It doesn't handle per-version sections, so we remove the headers and brackets. It expects symbols to be prefixed with an underscore. It errors if a listed symbol with no wildcards is not present in the output, so we append an asterisk to any symbol that doesn't already end in one.
* configure: define posix source on cygwinTimo Rothenpieler2016-10-02

* lavc: remove libfaac wrapperJosh de Kock2016-10-01
| | | | | | | | | | | There is really no need for two aac wrappers, we already have libfdk-aac which is better. Not to mention that faac doesn't even support HEv1, or HEv2. It's also under a license which is unusable for distribution, so it would only be useful to people who will compile their own ffmpeg, only use it themselves (which at that point should just use fdk-aac).

* cuvid: Use bundled headersPhilip Langdale2016-09-22
| | | | | | | | We need to remove the dynlink fanciness and replace it with normal function prototypes and update the include paths and configure logic. We don't need to explicitly check for PICPARMS now - they're going to be there.

* cuvid: Add hwaccels and decoders for remaining supported formatsPhilip Langdale2016-09-06
| | | | | | | | | | | cuvid/nvdecode also supports mpeg1, mpeg2, h.263/mpeg4-asp and mjpeg. It should, in theory, also support wmv3 via the vc1 support, given that vdpau supports this. However, it failed to play wmv3 samples which vdpau played correctly, so I'm not sure what to make of it.

* configure: check for dlsym as wellTimo Rothenpieler2016-09-03
| | | | | | | | | | | For some reason, when compiling with gcc-asan and a recent enough gcc version(seen on 5.3+ so far), linking dlopen works without -ldl, but dlsym fails with: undefined reference to symbol 'dlsym@@GLIBC_2.2.5' So this patchs checks for both dlopen and dlsym to work for determining if -ldl is needed.

* avcodec/nvenc: include nvEncodeAPI v7 SDK headerTimo Rothenpieler2016-08-28
| | | | | | | | | | | | | As Nvidia has put the most recent Video Codec SDK behind a double registration wall, of which one needs manual approval of a lenghty application, bundling this header saves everyone trying to use NVENC from that headache. The header is still MIT licensed and thus fine to bundle with ffmpeg. Not bundling this header would get ffmpeg stuck at SDK v6, which is still freely available, holding back future development of the NVENC encoder.

* Revert "configure: Enable GCC vectorization on ≥4.9 on x86"James Almer2016-07-09
| | | | | | | | | | | This reverts commit cb8646af24bd8e9627cc5e1c62b049a00fe0b07b. This change has brough more issues than benefits, between compilation time failures depending on flags used and code miscompilation causing runtime crashes. See the "[PATCH 2/2] configure: Enable GCC vectorization on ≥4.9" thread in the ffmpeg-devel mailing list for the relevant discussion.

| | | | | | | | | Visual Studio 2015 Update 3 introduced a new SSA optimizer, however it unfortunately causes miscompilations. Until it is fixed, the new optimizations are disabled and should be re-checked on subsequent compiler releases. Fixes recent FATE failure of fate-lavf-pam on VS2015.
