Damn you beat me too it.

Also its not even actually 1080p that video looks to be running in 2.40:1 (movie aspect ratio) so the height isn't taking up all the screen real-estate.

It is full 1080p, but that clip doesn't have content to the edge of the video frame, so you're seeing black bars at either side (which we are decoding, for what it matters!)

I may totally be missing something but 1080px should be the height. So if you're showing it at a movie resolution you're either at something like 2592x1080 which is actually better then 1080p (but kind of unlikely - very few monitors would support a screen res that high) or you're running at something like 1920x800 which is less then 1080.

Its still pretty slick, not sure what SOC you're using but for that kind of media playback it seems to be something in line with what we're seeing in a bunch of our Connected TVs

Actually if you look at Blu-ray, then in most cases those black bars you see, are encoded in the video. Blu-ray doesn't support other aspect ratios than 16:9 (and 4:3 legacy SD resolutions). So from video decoders point of view it's all 1080p even if some of those lines are just filled with black pixels.

usually videos from actual film are a lower (or higher) aspect ratio that the resolution of the monitor. in the 1080p case most often you get less than the full height since it was recorded that way.

p.s. their platform support decoding full 1080p, that demo just included less height.
