Do we have vp9? I thought the libvpx in m-c only did vp8. > But the opus in WebM 2.0 spec seems have not defined well already. I'm not happy with the state of the spec, but it is ready for implementation feedback. It would be valuable to have experience with the issues there before WebM 2 gets too far along in other implementations. > If we use the WebM 1.0, we may need to implement vorbis and mux the > vp8+vobris in WebM 1.0. Yes, we'd need to enable the vorbis encoder and add muxing support for vp8+vorbis. My instinct would be to do WebM 1 first, as it's lower risk. Software VP8 encoding uses less cpu and hardware support is better deployed. However it's a shame to not use the Opus encoder we've already implemented, and I intend to have vp9 playback support working for ff28. I'd say it depends on how much do you want to work on the experimental Opus muxing. -r _______________________________________________ dev-media mailing list [email protected] https://lists.mozilla.org/listinfo/dev-media
