Can FFmpeg crop gif image under 1 second? - swift

I am developing an iOS application about gif.
But I have a problem with gif cropping. Cropping gif spends so many times with FFmpeg.
(updated code)
These are the ffmpeg codes I've tried.
cropped images -> gif
ffmpeg -f image2 -i %d.jpg -vf 'scale=450:-1' output.gif
using concat command (cropped images -> gif)
ffmpeg -f concat -i tmp.txt output.gif
using crop filter
ffmpeg -i in.gif -filter:v "crop=out_w:out_h:x:y" out.gif
These codes are so slow when converting images to gif
or gif to cropped gif.
Is there a way to reduce the time to crop gif less than 1 second?
(updated2)
ffmpeg -i in.gif -filter:v "crop=out_w:out_h:x:y" out.gif

ffmpeg seems to output a video with a wrong codec?

I´m using ffmpeg with flutter and I create a video from a lot of images. The problem: ffmpeg seems to not create a video with a right codec or something else.... please check my description below for concrete informations.
First the code parts:
Creating video from images
-r $settings_fps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -shortest $tempPath/$videoFileName.mp4
Adding audio to the created video
-i ${finalSong.path} -i $videoPath -c:a aac -shortest $tempPath/$newVideoFileName.mp4
This is my video output from console on creating this video:

In general the created video works, but: If i try to save it as video with flutter gallery_saver to the device, this video will not saved. Other videos for example works well. But not the created with ffmpeg.
Can you find any reason for this in the ffmpeg output log? Thank you!

Videos for web playback usually require chroma sampling to be 4:2:0. FFmpeg, by default, will try to preserve the source sampling scheme, so your output is 4:2:2 (see yuvj422p in the output stream).
Use for step 1,
-r $settings_fps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -pix_fmt yuv420p $tempPath/$videoFileName.mp4
And in step 2, avoid re-encoding video
-i ${finalSong.path} -i $videoPath -c:v copy -c:a aac -shortest $tempPath/$newVideoFileName.mp4

GIMP get current image reference number to operate on current image

I have more than one image open, and I'd like to run scrip-fu functions on the currently selected image. How can I get the image reference number to the currently selected image so I can use the reference in other functions (e.g. (gimp-image-width 7))? I'm using GIMP 2.10.12.
Using (gimp-image-list) lists all the image references:
> (gimp-image-list)
(12 #(12 11 10 9 8 7 6 5 4 3 2 1))

I've been using (gimp-image-latest) for this, which should work for the general case

(define (gimp-image-list-items)
(cadr (gimp-image-list)))
(define (gimp-image-latest)
(aref (gimp-image-list-items) 0))
(define img (gimp-image-latest))
Then it's in img. E.g.:
> (gimp-image-get-layers img)

MATLAB Polygon Self Intersection - Delete Zero Volume Parts

I have a MATLAB polygon (below) which self intersects to make the zero volume part (which I will call a sliver) in the image (also below).
I am having a lot of trouble finding and removing the zero volume sliver.
Hope anyone can help. Thanks.

Zero volume slivers may occur when there are three or more consecutive points aligned. In this particular case those were:
366 1049
616 1049
615 1049
since they fall on the same horizontal line.
If you want to automate this, you should check every group of three consecutive points to see if they fall on the same line. If they do, you need to discard the one in the middle, according to appearance order.
In this particular case, the one in the middle is:
616 1049

Perl errors while trying to replace words in a large file

I have a huge 1.1 GB File. It contains only 1 line and 1167889705 characters. I want to replace all the occurences of "LFENT" by "\nLFENT".
I am using
perl 5, version 18, subversion 1 (v5.18.1) built for x86_64-linux –
Perl Script
perl -ne 's/LFENT/\nLFENT/g; print;' queries.txt

Problem
The script will work on the sample that I posted. But when I try it on the whole line I get the following error:
Substitution loop at -e line 1, <> line 1.

It is simplest to use LFENT as the record separator. That reduces the blocks to a more manageable size and ensures that there is no more than one LFENT to be replaced in each block
Command-line perl allows for setting the record separator with the -0 modifier, but the value of the parameter must be the code point in octal of a single character, and you can't specify a string. So here you have to set it once in a BEGIN block
Like this
perl -p -e'BEGIN{$/="LFENT"} s/LFENT/\nLFENT/'

By the way, it is unlikely to cause a problem but LFENT is always preceded by a space character in your example data. You may want to remove it by using s/\s*LFENT/\nLFENT for your substitution
And a look-ahead might be more appropriate too s/\s*(?=LFENT)/\n/ so that you don't have to remove and replace the unchanged part of the match

Try updating your perl to a more current version.
This was a known bug for a long time (fixed in v5.22.0): perl #123071: substitution loop issue with long strings
You can do so with the following commands (assuming you are on linux):
wget http://www.cpan.org/src/5.0/perl-5.22.1.tar.gz
tar -xzf perl-5.22.1.tar.gz
cd perl-5.22.1
./Configure -des -Dprefix=$HOME/localperl
make
make test
make install
Then test it by running $HOME/localperl/bin/perl -v and add it to your PATH using this: export PATH=$HOME/localperl/bin/:$PATH.

Exception when trying to refresh Clojure code in cider

I am using clojure in Emacs with cider and the cider repl (0.7.0). This is pretty fine, but whenever I run cider-referesh (or hit C-c C-x), I get an exception:
ClassNotFoundException clojure.tools.namespace.repl java.net.URLClassLoader$1.run (URLClassLoader.java:372)

What is the reason for this, and how can I fix it?

It seems that this exception was a bug, that has now been fixed in cider.

Try adding [org.clojure/tools.namespace "0.2.5"] to your project.clj
