It seems the 375.66 drivers can’t produce working vdpau for mpeg2 streams. The GTX 1050 supposedly has vdpau support, but vlc always punts to the CPU when confronted with a mpeg2 stream. Is the 375.66 driver buggy with regards to vdpau? Does something need to be patched? What’s going on? If anyone else has had success with this please reply.
The 375 driver is rather old and unsupported, please upgrade to a current 410/415 driver. Then run vdpauinfo and post the output if it still doesn’t work.
