direct3d11: fix the size of 10 bits I420 planes The pitch is for 16 bits data so we need to reduce the 16 bits texture width by that much. We we using twice too big textures and adjusting for the bug in the sampler. > http://git.videolan.org/gitweb.cgi/vlc.git/?a=commit;h=65d4eb8c6bb752f92f2593ed46275759f5e7d7e1 --- modules/video_chroma/d3d11_fmt.c | 2 +- modules/video_output/win32/d3d_dynamic_shader.c | 14 +++----------- 2 files changed, 4 insertions(+), 12 deletions(-) diff --git a/modules/video_chroma/d3d11_fmt.c b/modules/video_chroma/d3d11_fmt.c index 7a3efaa567..ec89837b78 100644 --- a/modules/video_chroma/d3d11_fmt.c +++ b/modules/video_chroma/d3d11_fmt.c @@ -807,7 +807,7 @@ int AllocateTextures( vlc_object_t *obj, d3d11_device_t *d3d_dev, ID3D11Texture2D_AddRef(slicedTexture); } else { texDesc.Height = planes[plane].i_lines; - texDesc.Width = planes[plane].i_pitch; + texDesc.Width = planes[plane].i_pitch / p_chroma_desc->pixel_size; hr = ID3D11Device_CreateTexture2D( d3d_dev->d3ddevice, &texDesc, NULL, &textures[plane] ); if (FAILED(hr)) { msg_Err(obj, "CreateTexture2D failed for plane %d.
