* avfilter: Add blue and violet noise generation filtersGeorge Boyle2017-07-19
| | | | | | | | | For the blue and violet noise, I took the pink and brown noise respectively and subtracted the offsets instead of adding them. When I eyeball the frequency spectrum of the resulting outputs it looks correct to me, i.e. the blue graph appears to be a mirror image of the pink, and the same can be said of the violet and the brown. I did not do anything else to confirm the correctness.

* dxva: add support for new dxva2 and d3d11 hwaccel APIswm42017-06-27
| | | | | | | | | | | | | | | This also adds support to avconv (which is trivial due to the new hwaccel API being generic enough). The new decoder setup code in dxva2.c is significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Merges Libav commit f9e7a2f95a7194a8736cc1416a03a1a0155a3e9f. Also adds untested VP9 support. The check for DXVA2 COBJs is removed. Just update your MinGW to something newer than a 5 year old release. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* lavu: add new D3D11 pixfmt and hwcontextwm42017-06-27
| | | | | | | | | | | | | | | | | | | | | | To be used with the new d3d11 hwaccel decode API. With the new hwaccel API, we don't want surfaces to depend on the decoder (other than the required dimension and format). The old D3D11VA pixfmt uses ID3D11VideoDecoderOutputView pointers, which include the decoder configuration, and thus is incompatible with the new hwaccel API. This patch introduces AV_PIX_FMT_D3D11, which uses ID3D11Texture2D and an index. It's simpler and compatible with the new hwaccel API. The introduced hwcontext supports only the new pixfmt. Frame upload code untested. Significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Merges Libav commit fff90422d181744cd75dbf011687ee7095f02875.

* doc/filters: Correct scale doc regarding w/h <= 0Kevin Mark2017-06-19
| | | | | | | | | | | | | | | | According to libavfilter/scale.c, if the width and height are both less than or equal to 0 then the input size is used for both dimensions. It does not need to be -1. -1:-1 is the same as 0:0 which is the same as -10:-42, etc. if (w < 0 && h < 0) eval_w = eval_h = 0; The documentation for the zscale filter has also been updated since the behavior is identical.

* libavfilter/scale2ref: Add constants for the primary inputKevin Mark2017-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Variables pertaining to the main video are now available when using the scale2ref filter. This allows, as an example, scaling a video with another as a reference point while maintaining the original aspect ratio of the primary/non-reference video. Consider the following graph: scale2ref=iw/6:-1 [main][ref] This will scale [main] to 1/6 the width of [ref] while maintaining the aspect ratio. This works well when the AR of [ref] is equal to the AR of [main] only. What the above filter really does is maintain the AR of [ref] when scaling [main]. So in all non-same-AR situations [main] will appear stretched or compressed to conform to the same AR of the reference video. Without doing this calculation externally there is no way to scale in reference to another input while maintaining AR in libavfilter. To make this possible, we introduce eight new constants to be used in the w and h expressions only in the scale2ref filter: * main_w/main_h: width/height of the main input video * main_a: aspect ratio of the main input video * main_sar: sample aspect ratio of the main input video * main_dar: display aspect ratio of the main input video * main_hsub/main_vsub: horiz/vert chroma subsample vals of main * mdar: a shorthand alias of main_dar Of course, not all of these constants are needed for maintaining the AR, but adding additional constants in line of what is available for in/out allows for other scaling possibilities I have not imagined. So to now scale a video to 1/6 the size of another video using the width and maintaining its own aspect ratio you can do this: scale2ref=iw/6:ow/mdar [main][ref] This is ideal for picture-in-picture configurations where you could have a square or 4:3 video overlaid on a corner of a larger 16:9 feed all while keeping the scaled video in the corner at its correct aspect ratio and always the same size relative to the larger video. I've tried to re-use as much code as possible. I could not find a way to avoid duplication of the var_names array. It must now be kept in sync with the other (the normal one and the scale2ref one) for everything to work which does not seem ideal. For every new variable introduced/removed into/from the normal scale filter one must be added/removed to/from the scale2ref version. Suggestions on how to avoid var_names duplication are welcome. var_values has been increased to always be large enough for the additional scale2ref variables. I do not forsee this being a problem as the names variable will always be the correct size. From my understanding of av_expr_parse_and_eval it will stop processing variables when it runs out of names even though there may be additional (potentially uninitialized) entries in the values array. The ideal solution here would be using a variable-length array but that is unsupported in C90. This patch does not remove any functionality and is strictly a feature patch. There are no API changes. Behavior does not change for any previously valid inputs. The applicable documentation has also been updated.

* lavc: remove libschroedinger encoding and decoding wrappersRostislav Pehlivanov2017-05-29
| | | | | | | | | The library has stopped being developed and Debian has removed it from its repositories citing security issues. The native Dirac decoder supports everything the library has and basic encoding support is still provided via the native vc2 (Dirac Pro, intra only version of Dirac) encoder. Hence, there's no reason to still support linking to the library and potentially leading users into security issues.
