將視頻分割成幀/圖像

Question

我有要求將5秒視頻分割爲來自iPhone的圖像/幀。

是否有可能使用客觀的C.Any庫可用於此？

幫助非常明顯。

謝謝，

有很多方法可以從視頻中獲取圖像。其中一些是： -

NSURL *videoURL = [NSURL fileURLWithPath:url]; 

MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:videoURL]; 

UIImage *thumbnail = [player thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame]; 

//Player autoplays audio on init 
[player stop]; 
[player release];
