+====== GPU Hardware Acceleration ======
+There are different ways to access hardware encoders and decoders. Vendors usually have their own APIs (NVIDIA has CUDA, Intel has QSV, AMD has AMF) and operating systems may also have their own APIs that use whatever HW capabilities are available (Windows has DXVA and D3D11VA, Linux has VAAPI, VDPAU and V4L, macOS has VideoToolbox). By merely adding -c:v h264_qsv to your first command, you're trying to use the VAAPI hardware initialization with the QSV encoder, which won't work for obvious reasons. You either use -hwaccel qsv with -c:v h264_qsv or -hwaccel vaapi with -c:v h264_vaapi.
