* lavu/cpu: disable MMX warning on non x86 platformsClément Bœsch2017-06-29
| | | | | We have AV_CPU_FLAG_ARMV8 == AV_CPU_FLAG_SSE3 which causes a trigger of this MMX warning on AArch64.

* dxva: support DXGI_FORMAT_420_OPAQUE decodingwm42017-06-27
| | | | | | | | | | | | | | Some devices (some phones, apparently) will support only this opaque format. Of course this won't work with CLI, because copying data directly is not supported. Automatic frame allocation (setting AVCodecContext.hw_device_ctx) does not support this mode, even if it's the only supported mode. But since opaque surfaces are generally less useful, that's probably ok. Merges Libav commit 5030e3856c2126fb829edb828f5aae011d178eb4. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* hwcontext_d3d11va: allocate staging texture lazilywm42017-06-27
| | | | | | | | | | Makes dealing with formats that can not be used for staging textures easier (DXGI_FORMAT_420_OPAQUE). It also saves memory if the staging texture is never needed, so this is a good thing. Merges Libav commit 98d73e4174333b37d961b79e1182be5a02156c02. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* hwcontext_d3d11va: fix crash on frames_init failurewm42017-06-27
| | | | | | | | | It appears in this case, frames_ininit is called twice (once by av_hwframe_ctx_init(), and again by unreffing the frames ctx ref). Merges Libav commit 086321c612185469ebb85a1887527c8915b488b7. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* d3d11va: Link directly to dxgi.dll and d3d11.dll functions if LoadLibrary is ↵Martin Storsjö2017-06-27
| | | | | | | | | | | | | unavailable When targeting the UWP API subset, the LoadLibrary function is not available (and the fallback, LoadPackagedLibrary, can't be used to load system DLLs). In these cases, link directly to the functions in the DLLs instead of trying to load them dynamically at runtime. Merges Libav commit fd1ffa1f10e940165035ccb79d4a6523da196062.

* 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.

* hwcontext: Improve allocation in derived contextsMark Thompson2017-06-14
| | | | | | | | | Use the flags argument of av_hwframe_ctx_create_derived() to pass the mapping flags which will be used on allocation. Also, set the format and hardware context on the allocated frame automatically - the user should not be required to do this themselves.

* hwcontext: Add frame context mapping for nontrivial contextsMark Thompson2017-06-14
| | | | | | | | | Some frames contexts are not usable without additional format-specific state in hwctx. This change adds new functions frames_derive_from and frames_derive_to to initialise this state appropriately when deriving a frames context which will require it to be set.

* hwcontext: Make it easier to work with device typesMark Thompson2017-06-14
| | | | | | | | Adds functions to convert to/from strings and a function to iterate over all supported device types. Also adds a new invalid type AV_HWDEVICE_TYPE_NONE, which acts as a sentinel value. (cherry picked from commit b7487f4f3c39b4b202e1ea7bb2de13902f2dee45)

* hwcontext_vaapi: Try to support the VDPAU wrapperMark Thompson2017-06-14
| | | | | | | | | | The driver is somewhat bitrotten (not updated for years) but is still usable for decoding with this change. To support it, this adds a new driver quirk to indicate no support at all for surface attributes. Based on a patch by wm4 <nfxjfg@googlemail.com>.

* x86inc: Remove argument from WIN64_RESTORE_XMMAnton Mitrofanov2017-06-09
| | | | | The use of rsp was pretty much hardcoded there and probably didn't work otherwise with stack_size > 0.
* x86inc: Prefer r14/r15 over r12/r13 on x86-64Henrik Gramner2017-06-09
| | | | | | | Due to a peculiarity in the ModR/M addressing encoding, the r12 and r13 registers sometimes requires an additional byte when used as a base register. r14 and r15 doesn't have that issue, so prefer using them.

* | avutil/hwcontext_dxva2: Don't improperly free IDirect3DSurface9 objectsAaron Levinson2017-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add dxva2_pool_release_dummy() and use it in call to av_buffer_create() in dxva2_pool_alloc(). Prior to this change, av_buffer_create() was called with NULL for the third argument, which indicates that av_buffer_default_free() should be used to free the buffer's data. Eventually, it gets to buffer_pool_free() and calls buf->free() on a surface object (which is av_buffer_default_free()). This can result in a crash when the debug version of the C-runtime is used on Windows. While it doesn't appear to result in a crash when the release version of the C-runtime is used on Windows, it likely results in memory corruption, since av_free() is being called on memory that was allocated using IDirectXVideoAccelerationService::CreateSurface().

* | videotoolbox: add hwcontext supportwm42017-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds tons of code for no other benefit than making VideoToolbox support conform with the new hwaccel API (using hw_device_ctx and hw_frames_ctx). Since VideoToolbox decoding does not actually require the user to allocate frames, the new code does mostly nothing. One benefit is that ffmpeg_videotoolbox.c can be dropped once generic hwaccel support for ffmpeg.c is merged from Libav. Does not consider VDA or VideoToolbox encoding. Fun fact: the frame transfer functions are copied from vaapi, as the mapping makes copying generic boilerplate. Mapping itself is not exported by the VT code, because I don't know how to test.
