Sometimes putting a gif in a pull request is really helpful for reviewers. If you’ve recorded a movie on an iOS simulator with xcrun simctl or just QuickTime, it’s very simple to convert them to animated .gifs
Example:
ffmpeg -i screen_recording.mov \
-s 415x925 \
-pix_fmt rgb24 \
-r 10 \
-f gif \
screen_recording.gif
Now it would be nice to have a function that could extract the video dimensions automatically 🤔 mdls 🤯
1 function gif-mov() {
2 movie=$1
3 height=$(mdls -name kMDItemPixelHeight ${movie} | grep -o '[0-9]\+')
4 width=$(mdls -name kMDItemPixelWidth ${movie} | grep -o '[0-9]\+')
5 dimensions="${width}x${height}"
6 ffmpeg -i ${movie} -s ${dimensions} -pix_fmt rgb24 -r 10 -f gif ${movie}.gif
7 }
Usage:
$ gif-mov ~/Desktop/cool-screen-recording.mov
