Revision 2.
</p>
<p>A script evaluating PSNR metric of two YUV420 frames
<strong>usage: psnr.py filename1.yuv filename2.yuv frame_width frame_height</strong></p>
<p>Alternatively if filename1 contains width and height in the form <strong>file-1200x1600.yuv</strong>,
the script will extract width and height of a frame from the filename. Then usage even simplier:
<strong>psnr.py filename1-1200x1600.yuv filename2.yuv</strong></p>
