Here's a scheme, I throw away every other frame and duplicate whatever the first frame. Compression can be made arbitrarily easy. Writing is not compression, dont confuse the two. It's a resolution format.ĭid anyone claim anything differently? Guess what? VLC does http streaming in exactly the same way you describe. That's why AirPlay on the Mac is limited to computer who have special hardware to do this encoding in realtime.ġ080p is not an encoding genius. So basically, software encoding of a full 1080p screen + actual work + streaming it, really can't be done well in realtime. Or on a Mac, take Quicktime X and use it to make a recording of all the screen while you do work.

Take your Dell Inspiron Laptop, take your 1080p video in whatever format you choose and use a software like Handbrake to ENCODE it to 1080p x264 and check if you can do it in realtime (which mean that if your movie last 1 hour, can your computer ENCODE the movie in x.264 faster than 1 hour ? If it can, try to do some other work while it does.) The same way it take longer for an author to write a book than it take for you to read it.

It's totally different.Įncoding is really taxing cpu way more than simple decoding. It's very easy to just send the file to another computer and let it decode the thing and show it.Ī feature like Airplay isn't about streaming some files over Wi-Fi (a thing you can already do with iTunes and an AppleTV.), it's about ENCODING the video output on the screen and THEN only stream it in realtime to the AppleTV.

Your 1080p video is already encoded, its an encoded file. You really don't understand the basic technology behind all of this.
