I want last frame of video and my code is shown below:

let asset : AVURLAsset = AVURLAsset(URL: videoURL, options: nil)
    let generate : AVAssetImageGenerator = AVAssetImageGenerator(asset: asset)
    generate.appliesPreferredTrackTransform = true

    var err : NSError? = nil
    var lastFrameTime = Int64(CMTimeGetSeconds(asset.duration))
    let time : CMTime = CMTimeMake(lastFrameTime, 30)
    let imgRef : CGImageRef = generate.copyCGImageAtTime(time, actualTime: nil, error: &err)
    let img : UIImage = UIImage(CGImage: imgRef)!

But I am not getting last frame , I am getting first frame, provide me solution for this.


You can get last frame of video in Objective-C as mentioned below:-

    AVURLAsset *asset = [AVURLAsset URLAssetWithURL:videoURL options:nil];
    AVAssetImageGenerator *generate = [AVAssetImageGenerator assetImageGeneratorWithAsset:asset];
    generate.appliesPreferredTrackTransform = YES;

    NSError *error;

    int64_t lastFrameTime = CMTimeGetSeconds(asset.duration)*60.0;
    CMTime time = CMTimeMake(lastFrameTime, 2);
    CGImageRef imgRef = [generate copyCGImageAtTime:time actualTime:nil error:&error];
    UIImage *image = [UIImage imageWithCGImage:imgRef];

Dump last frame of video file using ffmpeg/mencoder/transcode et. al , This isn't a complete solution, but it'll point you along the right path. Use ffprobe -​show_streams IN.AVI to get the number of frames in the video  The video player will change to look like the one shown below. There’s a seek bar at the bottom to navigate to the time in the video you want to capture a still from, two arrows that let you move to the next or previous frame, and a save button at the top that you will click when you’re ready to save the photo.


I used Pooja's code as a starting point but it doesn't get the last frame. it gets something close to the last frame. Here is my solution for getting the actual last frame. If frame accuracy is important, then you have to use:

imageGenerator.requestedTimeToleranceBefore = kCMTimeZero
imageGenerator.requestedTimeToleranceAfter = kCMTimeZero

Be aware that it may take longer to generate this frame accurate last frame so you probably want to do it on a background thread.

Here is the code I am using:

let imageGenerator = AVAssetImageGenerator(asset: asset!)
imageGenerator.appliesPreferredTrackTransform = true
imageGenerator.requestedTimeToleranceAfter = kCMTimeZero
imageGenerator.requestedTimeToleranceBefore = kCMTimeZero

let composition = AVVideoComposition(propertiesOfAsset: asset!)
let time = CMTimeMakeWithSeconds(asset!.duration.seconds, composition.frameDuration.timescale)

do {
    let imageRef = try imageGenerator.copyCGImageAtTime(time, actualTime: nil)
}
catch let error as NSError {
    print("Image generation failed with error \(error)")
}

Hope this helps.

How can I take a snapshot of the last frame of a video?, On the frame you would like to save, press F12 to render (you can also press Render image in Render at the top of the window, or Render in Properties >  I used Pooja's code as a starting point but it doesn't get the last frame. it gets something close to the last frame.

I have solved this , to get only last frame from video the code is following:

  let asset : AVURLAsset = AVURLAsset(URL: videoURL, options: nil)
    let generate : AVAssetImageGenerator = AVAssetImageGenerator(asset: asset)
    generate.appliesPreferredTrackTransform = true

    var err : NSError? = nil
    var lastFrameTime = Int64(CMTimeGetSeconds(asset.duration)*60.0)
    let time : CMTime = CMTimeMake(lastFrameTime, 2)
    let imgRef : CGImageRef = generate.copyCGImageAtTime(time, actualTime: nil, error: &err)
    let img : UIImage = UIImage(CGImage: imgRef)!

This is how I get last image of video in img variable.

Extract last frame of a video file · GitHub, Extract last frame of a video file. lastframe.sh. #!/bin/bash. fn="$1". of=${fn%.*}.jpg​. lf=`ffprobe -show_streams "$fn" 2> /dev/null | awk -F= '/^nb_frames/ { print  The program itself will save frames from a video file to a sequence of JPG images. There are four extraction methods to choose from, extract an image every number of frames, extract an image every number of seconds, take a total number of frames from the video or extract every single frame.


The accepted answer produce the first frame.

This code works (objective-c)

AVAsset* asset = [AVAsset assetWithURL:videoURL];
AVAssetImageGenerator *generate = [AVAssetImageGenerator assetImageGeneratorWithAsset:asset];
generate.requestedTimeToleranceAfter = kCMTimeZero;
generate.requestedTimeToleranceBefore = kCMTimeZero;
generate.appliesPreferredTrackTransform = YES;

NSError *error;
CMTime time = asset.duration;
CGImageRef imgRef = [generate copyCGImageAtTime:time actualTime:nil error:&error];
UIImage *image = [UIImage imageWithCGImage:imgRef];

The main lines here are :

generate.requestedTimeToleranceAfter = kCMTimeZero;
generate.requestedTimeToleranceBefore = kCMTimeZero;

and

CMTime time = asset.duration;

Extract the last frame and check the video info, implay(I). "" 1st Question: how i need to take out my last frame???? if i dont knw what is my frame go on. 2nd Question: how do i check ,the info of my video avi is​  Alternatively, you could use the Extend Frame functionality on the last frame of the video. That would allow you to extend it as long as you need it (just 1 frame if you want), and it should guarantee that the last frame shows up at the end.

How to end video on last frame vs. black screen?, I would like to have the last frame of my video be showing when the video ends rather than the automatic transition to a black screen. I have version 7. Putting the -ss before the -i is faster (and less precise) because ffmpeg does not decode the video to find the frame. I think this has something to do with keyframes. Because of this I have found it to be problematic with some videos that will produce a gray frame, whereas putting the -ss after the -i will work fine (though of course much slower).


How to Extract Frames from Video in Lightroom Classic, A guide on how to save a single frame from a video as a JPG using Lightroom Classic. Freeze a video frame for the duration of a clip You can freeze on the clip’s In point, Out point, or at marker 0 (zero), if present. Select a clip in a Timeline panel. To freeze a frame other than the In or Out point, open the clip in the Source Monitor, and set Marker 0 (zero) to the frame you want to freeze.
