It is nice to see technical comparisons like this one - and more of them are needed - but a more important discussion, in my opinion, should be about the fact that the VP8 camp is fundamentally about inclusiveness and the H.264 camp about exclusiveness. Cullen's comment in the meeting about the fact that there is only 4 browsers and that they all but Mozilla have a fully paid license for H.264 is symptomatic of the blindness of the H.264 camp to the need of the RTCWeb/Webrtc community at large. OTOH, the VP8 camp consistently demonstrated, as with the OP email, willingness to work with the community and make RTCWeb/Webrtc available and affordable to the whole spectrum of participants. As an independent developer, I do not need to look at the results of the tests to choose my camp. - -- Marc Petit-Huguenin Email: marc@petit-huguenin.org Blog: http://blog.marc.petit-huguenin.org Profile: http://www.linkedin.com/in/petithug -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBCAAGBQJRXabwAAoJECnERZXWan7EYlIQAJjfdocrPpiPNqjQJgG4OpxP lYE62oFsooJBP4a8hI0uxNFLMWLs/DsZC9LSYxXlvjWEs5kriOYrR48zWQHGuDQR W9VWepdHPrgrRTdh67nn0pxILj7zMhDahaeFonPxO9luvzX/1H76DLfXJ/glW1zv 6KBqqUhriHEb4IPN/f1VQ5Xpw5OQoD912/2wimkbzRjBeoDeHZ2olKLYEvpmiOQL /AYCe+xBi7Rr9ciJVksQ1JY2lL67RnKBP/23AYRlN0xNLnGnhafG7OIbBpMLWfCm qU7mdTZtyoz3IxnyLEC4eqQT7pI+rysA4yC2ormJkAbsJbw7qI10U8fzyZkfdPyn uOcVGwKdxjcQgJd1Z7F5QhgbWIAo3EuTIZ3Poa56oIPG4YQJ9dh66Iw8EIfh2GGh r6kYBY+uCkdwALcpa5Cp0iiB4NmmhzWfBVoGurkby2dX2sXh+nKAFPYaKI2vdYDw KfPkOPD2i9dzlEB867nLqzw1hElFvaW0PJAu+9RHuVLUlEda7XVIOCZYgBvy0R9n TZbkkCpJrcr9vD0g8ORSTx3uAUJF0z7c85++HpDD/YwmccQzyhVMuD6YPREtyim+ 9MtmluiI8ta6XEF9Q26KpCjg7Q0uLHhZEhS4jDEXFS3bDi1/bbM/Bw7tuiLAV2cC Y4OvDTukQl0GHTdMCOP6 =gcyM -----END PGP SIGNATURE-----
