IOS get thumbnails of local videos

+ (UIImage *) GetImage: (NSString *) Videourl

{

Avurlasset *asset = [[Avurlasset alloc] Initwithurl:[nsurl Fileurlwithpath:videourl] options:nil];

Avassetimagegenerator *gen = [[Avassetimagegenerator alloc] initwithasset:asset];

Gen.appliespreferredtracktransform = YES;

Cmtime time = cmtimemakewithseconds (0.0, 600);

Nserror *error = nil;

Cmtime Actualtime;

Cgimageref image = [Gen Copycgimageattime:time actualtime:&actualtime error:&error];

UIImage *thumb = [[UIImage alloc] initwithcgimage:image];

Cgimagerelease (image);

return thumb;

}

Need to add avfoundation and Coremedia.framework

The other way.

MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:videoURL]; moviePlayer.shouldAutoplay = NO; 

UIImage *thumbnail = [moviePlayer thumbnailImageAtTime:time timeOption:MPMovieTimeOptionNearestKeyFrame];

It's the same thing.

 
 + (UIImage *) Ffirstvideoframe: (NSString *) path  
 {  
      MPMoviePlayerController *MP = [[MPMoviePlayerController alloc]  
                                      initwithcontenturl:[nsurl FileURLWithPath:path]];   
     uiimage *img = [MP thumbnailimageattime:0.0  
                                    timeoption:mpmovietimeoptionnearestkeyframe] ;   
     [mp stop];  
     [mp release];  
      return img;  
}
