            Node.js: Converting MP4 to GIF (puppeteer-lottie)
            Asked 2022-Feb-20 at 10:06

            I am trying to convert a .mp4 file to .gif using NPM packages, but nothing seems to be working.

            I tried using gifski binary package (NPM) for this, but no luck. It says its a binary package and you can use it by child_process.spawn() or similar. I installed it with -g (global) flag and seems like its not recognized even with global flag. Not sure If you can set PATH or anything. Let me know if its possible.

            As for the other tries, I used gify and its just not doing anything (no file or error).

            I am getting the .mp4 file from puppeteer-lottie NPM package. Here's my code, if needed for testing:

            Fixing abrupt changes/transitions in animated ggplot
            Asked 2022-Jan-21 at 21:16

            I was wanting to make an animated ggplot of daily values for countries over the course of a year. I was able to do that thanks to some helpful questions/answers here.

            While the code below successfully makes a gif, the changes/transitions when countries move up or down/overtake one another is very abrupt (i.e instantaneous). It is not smooth like the examples in the linked post.

            I'm not entirely sure why this is happening and would really appreciate some help. Thanks in advance to anyone who is able to provide some insight. Code is below.

            The temporal resolution of your data is very high, you have 365 timepoints, but only 500 frames in your animation. These smooth switches therefore happen within 500 / 365 = ~1.4 frames and aren't visible.

            Either make your animation much longer, reduce the time resolution of the data, or manually code in transitions. For example, here's what happens if we give data only once a month:

            How to loop through a sequential series of files in a folder in R
            Asked 2021-Sep-27 at 14:44

            I have about 24,000 photos (JPG) saved across a few folders. What I'd like to do is develop an R script that goes through all images of the folder and creates a GIF animation for every sequential group of 8 photos. I already have GIF animation code figured out using the magick library, so I don't need help with that. What I need help with is how to develop the code that steps through the images in the folder and groups them by a factor of 8. For example, If I have a folder of 24 images, I need something that will loop through the folder create 3 GIF files based on the three groups of 8 images as follows: GIF 1: images 1-8 in the folder GIF 2: images 9-16 in the folder GIF 3: images 17-24 in the folder

            Here is the code I have so far, which assembles all images in the folder into a single GIF. I'm hoping there's an easy couple of lines of code that can be added that will step through every group of 8 images in the folder to produce a GIF animation. I would also like to name the output GIF file the same file name as the first image in the sequence.

            Below is an example of animating vehicle moving from A to B. [solved by @mrhellmann here, there are solutions also available]

            I want to animate vehicle moving from A to B and then wait at B for sometime and then return to A. Below is the code which has animations of both the trip (A-B and B-A).

            1. How can we merge osroute_sampled_1 and osroute_sampled_2 to create single animation?

            2. Also, how can we add wait time (make vehicle stationary for few seconds at B?

            Never really worked with sf and friends before, but after reading the docs I could imagine a solution like this to fulfill your needs.

            Idea

            Since sf are in fact extended data.frames they naturally come with an rbind functionality. Having said that, the whole task should be as easy as rbind'ing all the relevant paths together. As for the waiting time, simply repeat the last row in the sf a couple of times, which would give you the impression of the vehicle stopping at B (and A on the way back).

            gganimate object too large to render
            Asked 2021-Mar-23 at 13:55

            I've created a large gganim of a lorenz curve using packages ggplot2, gglorenz, gganimate, transformr and gifski. I've created the gganim plot using 'wealth_lorenz', a df of 5 variables and ~2.5 million rows using the below code,

            lorenz_chart <- ggplot(wealth_lorenz, aes(x = value, color = Limits)) + stat_lorenz() + transition_states(Time) + facet_wrap(~Limits)

            The gganim object created is 103.4MB in size.

            Understandably, it takes too long to render in Rstudio using animate(lorenz_chart). Is there an alternative that could be faster to run out? I understand it's a very large dataset with faceting so it may not be possible. Ideally I'd like to include the animation in a bookdown PDF_2 using the animate package (see here) if possible.

            Thanks for any help!

            The problem here really is the length of the data and the need to capture all of it. To that end, the stat_lorenz() function is a very resource-intensive calculation (which needs repeated many times), so I decided to take another route by calculating the formula of each curve and then plotting as normal using geom_line() - I recommend anyone else using this function for large datasets do the same. Thanks.

            Vulnerabilities

            No vulnerabilities reported

            Install gifski

            See releases page for executables. If you have Homebrew, you can also get it with brew install gifski. If you have Rust 1.49+, you can also build it from source with cargo install gifski.

            Support

            The tool optionally supports decoding video directly, but unfortunately it relies on ffmpeg 4.x, which may be very hard to get working, so it's not enabled by default. You must have ffmpeg and libclang installed, both with their C headers intalled in default system include paths. Details depend on the platform and version, but you usually need to install packages such as libavformat-dev, libavfilter-dev, libavdevice-dev, libclang-dev, clang. Please note that installation of these dependencies may be quite difficult. Especially on macOS and Windows it takes expert knowledge to just get them installed without wasting several hours on endless stupid installation and compilation errors, which I can't help with. If you're cross-compiling, try uncommenting [patch.crates-io] section at the end of Cargo.toml, which includes some experimental fixes for ffmpeg. Once you have dependencies installed, compile with cargo build --release --features=video or cargo build --release --features=video-static. When compiled with video support ffmpeg licenses apply. You may need to have a patent license to use H.264/H.265 video (I recommend using VP9/WebM instead).
