* lavc: implement an ATRAC9 decoderRostislav Pehlivanov2018-07-03
| | | | | | | | | | | | | | | | | | | | This commit implements a full ATRAC9 decoder, a simple low-delay codec developed by Sony and used in most PSVita games, some PS3 games and some PS4 games. Its similar to AAC in that it uses Huffman coded scalefactors but instead of vector quantization it just Huffman codes the spectral coefficients (in a way similar to how Opus splits band energy coding into coarse and fine precision). It opts to write rather large Huffman codes by packing several small coefficients into one Huffman coded symbol, though I don't believe this increases efficiency at all. Band extension implements SBC in a simple way, first it mirrors the lower spectrum onto the higher frequencies and then it uses one of 5 filters to shape it. Noise substitution is implemented via 2 of them. Unlike previous ATRAC codecs, there's no QMF, this is a standard MDCT codec. Based off of the reverse engineering work of Alex Barney.

* configure: error out on unsupported MSVC versionsRostislav Pehlivanov2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | The FATE tests for MSVC versions older than 2013 are untested in FATE and apparently are no longer supported. This commit makes the configure process error out in case an older version is used, and suggests to use a supported version of MSVC to compile. This also changes the documentation to reflect this. As discussed on IRC: 2018-05-12 19:45:16 jamrial then again, most of those were for old msvc, and i think we're not supporting versions older than 2013 (first one c99 compliant) anymore 2018-05-12 19:45:43 +JEEB yea, I think 2013 update 2 is needed 22:53 <@atomnuker> nevcairiel: which commit broke/unsupported support for msvc 2013? 23:23 <@atomnuker> okay, it was JEEB 23:25 <+JEEB> which was for 2012 and older 23:25 <+JEEB> and IIRC we no longer test those in FATE so that was my assumption 23:26 <+JEEB> 2013 is when MS got trolled enough to actually update their C part 23:26 <+JEEB> aand actually advertised FFmpeg support 23:26 <+JEEB> (although it was semi-failing until VS2013 update 1 or 2) Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

| | | | | This does require libmysofa with today's latest commit (https://github.com/hoene/libmysofa/commit/08f243d1ec35f6f794aedeb4b187d9f9353bdbc1). They already had a pkg-config file, but the dependencies weren't setup right. Until now.
* configure: fix configure check for lilv-0Niklas Haas2018-05-13
| | | | | | | | | | This should be included as `<lilv/lilv.h>`, same as is done in af_lv2.c. Forcing the extra lilv-0 breaks platforms where the include dir is `/usr/include/lilv/lilv.h` rather than `/usr/include/lilv-0/lilv/lilv.h`. The new include path works for both, because the `pkg-config --cflags` includes `-I/usr/include/lilv-0`.

* avformat: add vapoursynth wrapperwm42018-05-04
| | | | | | | | | | | | | This can "demux" .vpy files. Autodetection of .vpy scripts is intentionally not done, because it would be a major security issue. You need to force the format, for example with "-f vapoursynth" for the FFmpeg CLI tools. Some minor code copied from other LGPL parts of FFmpeg. I did not find a good way to test a few of the more obscure VS features, like VFR nodes, compat pixel formats, or nodes with dynamic size/format changes. These can be easily implemented on demand.

| | | | | | | | | When using clang-cl it expects parameters passed in MSVC-style, so appropriate toolchain should be selected. As soon as both clang and clang-cl report themselfs as "clang" with -v option the only chance to detect clang-cl is passing -? option to both which is valid for clang-cl.exe and not for clang.exe.

* arm: swscale: Only compile the rgb2yuv asm if .dn aliases are supportedMartin Storsjö2018-03-31
| | | | | | | | | | | | | | | Vanilla clang supports altmacro since clang 5.0, and thus doesn't require gas-preprocessor for building the arm assembly any longer. However, the built-in assembler doesn't support .dn directives. This readds checks that were removed in d7320ca3ed10f0d, when the last usage of .dn directives within libav were removed. Alternatively, the assembly could be rewritten to not use the .dn directive, making it available to clang users. Signed-off-by: Martin Storsjö <martin@martin.st>
