VLCKit on iOS has no fps when playing streaming

When using mobileVLCKit.framework to play a live view streaming via RTSP protocol, I can't get fps info even if the displaying view is correctly shown.

Here is my code

NSLog(@"%.1f FPS", self.player.framesPerSecond);

The result is always "0.0 FPS", and is not reasonable.

I used framesPerSecond since fps is deprecated, as said in http://cocoadocs.org/docsets/MobileVLCKit/2.2.1/Classes/VLCMediaPlayer.html

Tracing to VLC source and I found

- (float)framesPerSecond
{
    return libvlc_media_player_get_fps(_playerInstance);  
}

it looks correct, but I still don't know why the result is wrong.

Could someone give me suggestion or some work around method to get fps info?

Any reply would be appreciated. Thanks!

We don't enable statistics on iOS / within MobileVLCKit by default, so any statistic value will always be 0. To enable it, you need to compile the framework yourself.

To enable stats, remove @"--no-stats" from VLCLibrary.m. Further, after the build script downloaded MobileVLCKit/ImportedSources/vlc, stop its execution, edit MobileVLCKit/ImportedSources/vlc/extras/package/ios/build.sh, remove the line stats from the blacklist, and restart the script.
