* libavutil/hwcontext_dxva2: Add check for possible errors from ↵Humberto Ribeiro2018-01-04
| | | | | | | | | | GetAdapterDisplayModeEx This prevents a possible crash in CreateDeviceEx when using faulty response from GetAdapterDisplayModeEx and allows ffmpeg to fallback to classic d3d9. Signed-off-by: wm4 <nfxjfg@googlemail.com>

* 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().

| * hwcontext_dxva2: split transfer_data() into upload/download functionsAnton Khirnov2016-11-18
| | | | | | | | | | | | Just the presence of a hw frames context is not enough to detect whether the transfer is an upload or a download, because hw frames mapped to system memory will have a hw frames context attached.

| | | | | | | | | | | | D3DLOCK_READONLY properly corresponds to the absence of the write flag, not to the presence of the read flag, while D3DLOCK_DISCARD is equivalent to the overwrite flag.
