Video Codec Info

RTCWeb – IETF84

Goal

• The goal of this presentation is to list information that people wish they could have which would help them decide between VP8 and H.264/AVC

• Construct a list of things we wish we knew• See if we can find people willing to track down

that information and send a summary to the list (or as an internet draft) before Oct 15

• Want to agree on way forward

Image Quality

• How does the image quality compare at common bitrates for interactive video – Lack of clarity about comparison to High Profile vs.

Baseline

Software Codecs

• What resolutions / frame rate can be done on in software on some common systems

Power Consumption of Hardware VS Software Implementation

• How much power is used? What resolution/frame rates? Overall impact on battery life of mobile devices

Hardware Support

• List of devices supporting both

IPR Status

• What is actually known about IPR disclosures?• At what point will more information be

available?• What other information could we get?

Going Forward

• Consensus we need at least one MTI video codec

• Information to list or in ID by Oct 15 • Proponents sends pro/con by Oct 15• Try and take consensus call at IETF 85

• If that fails, alternative process• Plan to try and get consensus on which alternative

process before IETF 85
