I am capturing video it works fine but i want to get thumbnail of that video and show it in ImageView any idea how to get this below is my code.
if ([type isEqualToString:(NSString *)kUTTypeVideo] || [type isEqualToString:(NSString *)kUTTypeMovie])
{
NSURL*videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSLog(#"found a video");
videoData = [[NSData dataWithContentsOfURL:videoURL] retain];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSDateFormatter *dateFormat = [[[NSDateFormatter alloc] init] autorelease];
[dateFormat setDateFormat:#"dd-MM-yyyy_HH:mm:SS"];
NSDate *now = [[[NSDate alloc] init] autorelease];
NSDate* theDate = [dateFormat stringFromDate:now];
NSString*myDate=[dateFormat stringFromDate:theDate];
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"Default Album"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil];
NSString*test=#"test";
NSString*testUser=[test stringByReplacingOccurrencesOfString:#" " withString:#""];
videopath= [[[NSString alloc] initWithString:[NSString stringWithFormat:#"%#/%#.mov",documentsDirectory,testUser]] autorelease];
BOOL success = [videoData writeToFile:videopath atomically:NO];
NSLog(#"Successs:::: %#", success ? #"YES" : #"NO");
NSLog(#"video path --> %#",videopath);
NSURL *movieURL = [NSURL fileURLWithPath:videopath];
AVURLAsset *avUrl = [AVURLAsset assetWithURL:movieURL];
CMTime time = [avUrl duration];
int seconds = ceil(time.value/time.timescale);
// durationTime=[NSString stringWithFormat:#"%d",seconds];
// insertTime=[NSString stringWithFormat:#"%d",seconds];
NSString*messageA=[NSString stringWithFormat:#"You have recorded video of duration of %d seconds ",seconds];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Alert" message:messageA
delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
NSDate* date = [NSDate date];
NSDateFormatter* formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy-MM-dd HH:MM:SS"];
//[formatter setDateFormat:#"MM-dd-yyyy"];
NSString* str = [formatter stringFromDate:date];

Answer 1

Try this one:
#import<AssetsLibrary/AssetsLibrary.h>
#import<AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>
#import <CoreMedia/CoreMedia.h>
#import <MediaPlayer/MediaPlayer.h>
//create thumbnail from video
AVAsset *asset = [AVAsset assetWithURL:url];// url= give your url video here
AVAssetImageGenerator *imageGenerator = [[AVAssetImageGenerator alloc]initWithAsset:asset];
CMTime time = CMTimeMake(1, 5);//it will create the thumbnail after the 5 sec of video
CGImageRef imageRef = [imageGenerator copyCGImageAtTime:time actualTime:NULL error:NULL];
UIImage *thumbnail = [UIImage imageWithCGImage:imageRef];
cell.backGround.image=thumbnail;// whichever imageview you want give this image
it will help you.

Answer 2

add that MPMoviePlayerController (see below) is a much faster option. The code above takes a good 5-10 seconds to generate a thumbnail, and also you can show in UIImageview
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];

Answer 3

#import <AVFoundation/AVFoundation.h>
-(UIImage *)generateThumbImage : (NSString *)filepath {
NSURL *url = [NSURL fileURLWithPath:filepath];
AVAsset *asset = [AVAsset assetWithURL:url];
AVAssetImageGenerator *imageGenerator = [[AVAssetImageGenerator alloc]initWithAsset:asset];
CMTime time = [asset duration];
time.value = 1000; //Time in milliseconds
CGImageRef imageRef = [imageGenerator copyCGImageAtTime:time actualTime:NULL error:NULL];
UIImage *thumbnail = [UIImage imageWithCGImage:imageRef];
CGImageRelease(imageRef); // CGImageRef won't be released by ARC
return thumbnail;
}
