[Libav-user] Video Quality Analyzer - implement which features?

[Rafael do Nascimento Pereira]

Hi Wesley,

i would include a PSNR, Quantization, Bit Rate, GOP Length, Aspect Ratio,
Color Format. There are some options the are common to any video format and
other are
specific.

I suggest you take a look at this site, maybe you can get some ideas:
