哪个iOS参考可以在iPad mini上播放实时视频？

Question

The iPad mini app needs to live display video only uncompressed grayscale 640x480 pixel data through a TCP/IP socket through USB connection from a Windows-7 computer.

Which is the best iOS framework to do this?

Answer 1

Either AVPlayer or MPMoviePlayerController are baked in and can play video. In your case, I'd recommend MPMoviePlayerController because AVPlayer doesn't come with controls (you'd have to implement your own play/pause buttons, scrub bar, etc).

Both implementations will play streaming content or fixed length files. Since you have streaming content, you'll have to format it (transcode it) in a way iOS will understand. This means HTTP Live Streaming (HLS) .

Converting your pixel data into HLS is by far the hardest part of the problem. There are cloud service providers which can do this such as Zencoder's Live Streaming service . That relies on an incoming RTMP stream, for example from Flash Media Live Encoder .

If you don't want to use HLS for encoding your stream, then you'll have to implement your own video rendering engine in C for your custom pixel data. I'm not exactly sure where to get started with that, but my guess would be somewhere in Core Data . Good luck!
