不知是否与v.to(MDK_NS::PixelFormat::RGB24)得到的高度是 1088有关,只要高度是16的倍数的视频,似乎没有问题

渲染的结果是正确的。d3d11硬解高度为了对齐1080输出为1088，to()的时候没裁掉多余的行

那实际渲染是不是也是 1088

渲染是1080

那就有头疼了,我在计算实际显示高度的时候不加8,我绘制内容始终与视频有偏差

你用软解试试，其他宽高的视频也试试。如果你要知道视频帧上一点在画布上的坐标，不需要自己算，可以用 https://github.com/wang-bin/mdk-sdk/wiki/Player-APIs#void-mappointmapdirection-dir-float-x-float-y-float-z--nullptr-void-vo_opaque--nullptr

比如视频右下角坐标

float x = 1.0f, y = 1.0f;
player.mapPoint(FrameToViewport, &x, &y, ...);

反过来也可以。可以把左上角右下角都获取下作差看看宽高对不对

这个是 m_player->setDecoders(MDK_NS::MediaType::Video, {"FFmpeg"}); 这样的效果

这个是 m_player->setDecoders(MDK_NS::MediaType::Video, {"MFT:d3d=11", "hap", "D3D11", "DXVA", "CUDA", "FFmpeg", "dav1d"});

硬解码的感觉偏差有点大，但是他们实际显示视频的宽高又一致

我是在 onFrame 取得帧数据给到模型，我现在不确定是to的时候有误差还是实际绘制
const auto rgb = v.to(MDK_NS::PixelFormat::RGB24, 1600, 900);

就是方框和方框里面的点或线,软解的点或线都在方框里面, 硬解的某些点和线不在方框里面
