In Search of Better Encoding Quality for WebRTC

Suffice it to say that Web­RTC is finally out of kindergarten and moving into the elementary grades. Which grade exactly? Well, that likely depends on which web browser you're using and which server technology or platform your Web­RTC implementation uses.

New Rules of Codec Development

The game has changed for new codecs entering the market.

It's Time to Retire PSNR

Peak signal-to-noise ratio is poor predictor of subjective video quality. So why are PSNR comparisons used in almost all codec comparisons?
