gst-launch command to play a video using vaapi hardware acceleration

Question

I need two gst-launch-1.0 command lines

1) The first one is simple to play a video (.mp4) without using any hardware acceleration.

2) The sencond one is to play the video (.mp4) using hardware acceleration, I am using Intel HD graphics with the i965 driver.

I already installed the gstreamer plugins.

Any help would be appreciated.
