MPMoviePlayerController : a way to get used bandwidth ?

Question

Hello everyone !

I would like to check used bandwidth when playing a video with MPMoviePlayerController to be able to play a video which matched client bandwidth.

For now, I download a part of my file by using NSURLConnection and I can find bandwidth. But I think it's not a good idea to download more data than expected (and the goal is to use as less bandwidth as possible).

Does a 'current downloaded bytes' property, or something like that, exist ? I hope you can help me.

Thanks a lot !

Take a look at the Reachability sample code, it will help you determine if the client is on WiFi,WWAN (3G/Edge), etc. You can make certain assumptions based on these findings. If you want exact speed, you'll download a file and check the speed.

You may want to look into HTTP video streaming, you can provide different (varying level of quality) versions of the video for each connection speed. The server determines the version to send.

Some docs on HTTP Streaming:
