* hwcontext_internal: add ff_hwframe_map_replaceRostislav Pehlivanov2018-06-21
| | | | | | Used to fix unmapping when no direct interop exists between APIs. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* hwcontext: Do not call device_init again when deriving an existing deviceMark Thompson2018-05-15
| | | | | | The change in 309d660775e2b47af6723a0477c4d753bc0c54f4 to call device_init when doing derivation missed this case - we should only call it if we actually made a new device.

| * lavu: add new D3D11 pixfmt and hwcontextwm42017-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Diego Biurrun <diego@biurrun.de>
| * hwcontext: Improve allocation in derived contextsMark Thompson2017-04-30
| | | | | | | | | | | | | | 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 Thompson2017-04-30
| | | | | | | | | | | | | | 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 Thompson2017-03-20
| | | | | | | | | | | | 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.
| * hwcontext: Add device derivationMark Thompson2017-03-20
| | | | | | | | | | Creates a new device context from another of a different type which refers to the same underlying hardware.
* | hwcontext: Perform usual initialisation on derived device contextsMark Thompson2017-10-09
| | | | | | | | | | | | | | The initialisation should be common. For libmfx, it was previously happening in the derivation function and this moves it out. For VAAPI, it fixes some failures when deriving from a DRM device because this initialisation did not run.

* | 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.

| * hwcontext: Hardware frame mappingMark Thompson2016-11-03
| | | | | | | | | | | | | | | | | | | | Adds the new av_hwframe_map() function, which allows mapping between hardware frames and normal memory, along with internal support for implementing it. Also adds av_hwframe_ctx_create_derived(), for creating a hardware frames context associated with one device using frames mapped from another by some hardware-specific means.
