Qsvh264enc not using the dedicated hardware video encoder

Application Development

Hi all,

I’m writing a streaming application using a H264 encoder and I use a 12th Gen Intel CPU (i7-1255U) precisely.
I’m using qsvh264enc and I realized it uses the GPU but the “3D” engine part compared to “d3d12h264enc” or even “qsvjpegenc” that is using the dedicated hardware labeled “Video decode” part. On Windows:

qsvh264enc_vs_d3d12h264enc
qsvh264enc_vs_d3d12h264enc1092×190 47.5 KB

Isn’t it supposed to use the hardware accelerated video encoder?
Is this due to some settings? I tried all the different profiles (even the supported ones from Intel Hardware Accelerated Video Encoder with no change, I use the default plugin settings as well.

Thanks for your insights!
