Firstly, make sure that your hardware supports the required video codec. The list of codecs supported by your GPU is available via vainfo and vdpauinfo commands for VAAPI and VDPAU decoding APIs respectively. The codec used in your video file is available in mpv log. If your GPU supports the required codec, but mpv doesn't do hardware decoding, try with --hwdec-codecs=all option.
