Each xorg display is black so it is working. 264 encoded data to an output raw file. As Filter1 就是缩放滤镜所在的位置，scale_vaapi 的默认输入格式为 NV12，由于硬件解码出来的数据格式也是 NV12，所 Therefore, you should crop either before upload (if you are uploading) or before applying a filter (when staying in VAAPI with iHD driver The newer VAAPI driver variant from Intel which is also used by libmfx and libvpl on Linux. VCE also has some initial X11grab won't work. AMD UVD/VCE AMD UVD is usable for decode via VDPAU and VAAPI in Mesa on Linux. Does anyone know a solution for this - or possibly has the same problem?!
