Webcaster X2 allows streams of up to 1080p to Facebook. However, we’ve not seen anywhere in the Facebook ecosystem where you can watch 1080p. Anyone else seeing 1080p on FB somewhere?
Facebook has recently enable the 1080 streaming feature, however it appears that Facebook is still working on updating the playback feature to 1080P. I believe the 1080P playback feature will also only be available with 1080P uploaded/streamed content, so that any video previously uploaded or streamed in 720P will still only provide 720 as the highest playback option.
