direct3d11: use D3D11_MAP_WRITE to update the shader constants Otherwise the other fields are lost when updating one field (cherry picked from commit 73b5de4394f0bc5e076c0514257b4b6417ed179b) Signed-off-by: Jean-Baptiste Kempf <j...@videolan.org> > http://git.videolan.org/gitweb.cgi/vlc/vlc-3.0.git/?a=commit;h=eb1295e704d5a4b794ddffb5bfcf3e2cc0b01b91 --- modules/video_output/win32/direct3d11.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/modules/video_output/win32/direct3d11.c b/modules/video_output/win32/direct3d11.c index 435ad00208..fa50bce6a7 100644 --- a/modules/video_output/win32/direct3d11.c +++ b/modules/video_output/win32/direct3d11.c @@ -1048,7 +1048,7 @@ static void UpdateQuadLuminanceScale(vout_display_t *vd, d3d_quad_t *quad, float if (quad->f_luminance_scale == luminanceScale) return; - HRESULT hr = ID3D11DeviceContext_Map(sys->d3d_dev.d3dcontext, (ID3D11Resource *)quad->pPixelShaderConstants[0], 0, D3D11_MAP_WRITE_DISCARD, 0, &mappedResource); + HRESULT hr = ID3D11DeviceContext_Map(sys->d3d_dev.d3dcontext, (ID3D11Resource *)quad->pPixelShaderConstants[0], 0, D3D11_MAP_WRITE, 0, &mappedResource); if (SUCCEEDED(hr)) { PS_CONSTANT_BUFFER *dst_data = mappedResource.pData; quad->f_luminance_scale = luminanceScale; @@ -2882,7 +2882,7 @@ static void UpdateQuadOpacity(vout_display_t *vd, const d3d_quad_t *quad, float vout_display_sys_t *sys = vd->sys; D3D11_MAPPED_SUBRESOURCE mappedResource; - HRESULT hr = ID3D11DeviceContext_Map(sys->d3d_dev.d3dcontext, (ID3D11Resource *)quad->pPixelShaderConstants[0], 0, D3D11_MAP_WRITE_DISCARD, 0, &mappedResource); + HRESULT hr = ID3D11DeviceContext_Map(sys->d3d_dev.d3dcontext, (ID3D11Resource *)quad->pPixelShaderConstants[0], 0, D3D11_MAP_WRITE, 0, &mappedResource); if (SUCCEEDED(hr)) { PS_CONSTANT_BUFFER *dst_data = mappedResource.pData; dst_data->Opacity = opacity; _______________________________________________ vlc-commits mailing list vlc-commits@videolan.org https://mailman.videolan.org/listinfo/vlc-commits
